-attachment-fu
-=============
-
-attachment_fu is a plugin by Rick Olson (aka technoweenie <http://techno-weenie.net>) and is the successor to acts_as_attachment.  To get a basic run-through of its capabilities, check out Mike Clark's tutorial <http://clarkware.com/cgi/blosxom/2007/02/24#FileUploadFu>.
-
-
-attachment_fu functionality
-===========================
-
-attachment_fu facilitates file uploads in Ruby on Rails.  There are a few storage options for the actual file data, but the plugin always at a minimum stores metadata for each file in the database.
-
-There are four storage options for files uploaded through attachment_fu:
-  File system
-  Database file
-  Amazon S3
-  Rackspace (Mosso) Cloud Files
-
-Each method of storage many options associated with it that will be covered in the following section.  Something to note, however, is that the Amazon S3 storage requires you to modify config/amazon_s3.yml, the Rackspace Cloud Files storage requires you to modify config/rackspace_cloudfiles.yml, and the Database file storage requires an extra table.
-
-
-attachment_fu models
-====================
-
-For all three of these storage options a table of metadata is required.  This table will contain information about the file (hence the 'meta') and its location.  This table has no restrictions on naming, unlike the extra table required for database storage, which must have a table name of db_files (and by convention a model of DbFile).
-  
-In the model there are two methods made available by this plugins: has_attachment and validates_as_attachment.
-
-has_attachment(options = {})
-  This method accepts the options in a hash:
-    :content_type     # Allowed content types.
-                      # Allows all by default.  Use :image to allow all standard image types.
-    :min_size         # Minimum size allowed.
-                      # 1 byte is the default.
-    :max_size         # Maximum size allowed.
-                      # 1.megabyte is the default.
-    :size             # Range of sizes allowed.
-                      # (1..1.megabyte) is the default.  This overrides the :min_size and :max_size options.
-    :resize_to        # Used by RMagick to resize images.
-                      # Pass either an array of width/height, or a geometry string.
-    :thumbnails       # Specifies a set of thumbnails to generate.
-                      # This accepts a hash of filename suffixes and RMagick resizing options.
-                      # This option need only be included if you want thumbnailing.
-    :thumbnail_class  # Set which model class to use for thumbnails.
-                      # This current attachment class is used by default.
-    :path_prefix      # Path to store the uploaded files in.
-                      # Uses public/#{table_name} by default for the filesystem, and just #{table_name} for the S3 and Cloud Files backend.  
-                      # Setting this sets the :storage to :file_system.
-    :partition        # Whether to partiton files in directories like /0000/0001/image.jpg. Default is true. Only applicable to the :file_system backend.
-    :storage          # Specifies the storage system to use..
-                      # Defaults to :db_file.  Options are :file_system, :db_file, :s3, and :cloud_files.
-    :cloudfront       # If using S3 for storage, this option allows for serving the files via Amazon CloudFront.
-                      # Defaults to false.
-    :processor        # Sets the image processor to use for resizing of the attached image.
-                      # Options include ImageScience, Rmagick, and MiniMagick.  Default is whatever is installed.
-    :uuid_primary_key # If your model's primary key is a 128-bit UUID in hexadecimal format, then set this to true.
-    :association_options  # attachment_fu automatically defines associations with thumbnails with has_many and belongs_to. If there are any additional options that you want to pass to these methods, then specify them here.
-    
-
-  Examples:
-    has_attachment :max_size => 1.kilobyte
-    has_attachment :size => 1.megabyte..2.megabytes
-    has_attachment :content_type => 'application/pdf'
-    has_attachment :content_type => ['application/pdf', 'application/msword', 'text/plain']
-    has_attachment :content_type => :image, :resize_to => [50,50]
-    has_attachment :content_type => ['application/pdf', :image], :resize_to => 'x50'
-    has_attachment :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
-    has_attachment :storage => :file_system, :path_prefix => 'public/files'
-    has_attachment :storage => :file_system, :path_prefix => 'public/files', 
-                   :content_type => :image, :resize_to => [50,50], :partition => false
-    has_attachment :storage => :file_system, :path_prefix => 'public/files',
-                   :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
-    has_attachment :storage => :s3
-    has_attachment :store => :s3, :cloudfront => true
-    has_attachment :storage => :cloud_files
-
-validates_as_attachment
-  This method prevents files outside of the valid range (:min_size to :max_size, or the :size range) from being saved.  It does not however, halt the upload of such files.  They will be uploaded into memory regardless of size before validation.
-  
-  Example:
-    validates_as_attachment
-
-
-attachment_fu migrations
-========================
-
-Fields for attachment_fu metadata tables...
-  in general:
-    size,         :integer  # file size in bytes
-    content_type, :string   # mime type, ex: application/mp3
-    filename,     :string   # sanitized filename
-  that reference images:
-    height,       :integer  # in pixels
-    width,        :integer  # in pixels
-  that reference images that will be thumbnailed:
-    parent_id,    :integer  # id of parent image (on the same table, a self-referencing foreign-key).
-                            # Only populated if the current object is a thumbnail.
-    thumbnail,    :string   # the 'type' of thumbnail this attachment record describes.  
-                            # Only populated if the current object is a thumbnail.
-                            # Usage:
-                            # [ In Model 'Avatar' ]
-                            #   has_attachment :content_type => :image, 
-                            #                  :storage => :file_system, 
-                            #                  :max_size => 500.kilobytes,
-                            #                  :resize_to => '320x200>',
-                            #                  :thumbnails => { :small => '10x10>',
-                            #                                   :thumb => '100x100>' }
-                            # [ Elsewhere ]
-                            # @user.avatar.thumbnails.first.thumbnail #=> 'small'
-  that reference files stored in the database (:db_file):
-    db_file_id,   :integer  # id of the file in the database (foreign key)
-    
-Field for attachment_fu db_files table:
-  data, :binary # binary file data, for use in database file storage
-
-
-attachment_fu views
-===================
-
-There are two main views tasks that will be directly affected by attachment_fu: upload forms and displaying uploaded images.
-
-There are two parts of the upload form that differ from typical usage.
-  1. Include ':multipart => true' in the html options of the form_for tag.
-    Example:
-      <% form_for(:attachment_metadata, :url => { :action => "create" }, :html => { :multipart => true }) do |form| %>
-      
-  2. Use the file_field helper with :uploaded_data as the field name.
-    Example:
-      <%= form.file_field :uploaded_data %>
-
-Displaying uploaded images is made easy by the public_filename method of the ActiveRecord attachment objects using file system, s3, and Cloud Files storage.
-
-public_filename(thumbnail = nil)
-  Returns the public path to the file.  If a thumbnail prefix is specified it will return the public file path to the corresponding thumbnail.
-  Examples:
-    attachment_obj.public_filename          #=> /attachments/2/file.jpg
-    attachment_obj.public_filename(:thumb)  #=> /attachments/2/file_thumb.jpg
-    attachment_obj.public_filename(:small)  #=> /attachments/2/file_small.jpg
-
-When serving files from database storage, doing more than simply downloading the file is beyond the scope of this document.
-
-
-attachment_fu controllers
-=========================
-
-There are two considerations to take into account when using attachment_fu in controllers.
-
-The first is when the files have no publicly accessible path and need to be downloaded through an action.
-
-Example:
-  def readme
-    send_file '/path/to/readme.txt', :type => 'plain/text', :disposition => 'inline'
-  end
-  
-See the possible values for send_file for reference.
-
-
-The second is when saving the file when submitted from a form.
-Example in view:
- <%= form.file_field :attachable, :uploaded_data %>
-
-Example in controller:
-  def create
-    @attachable_file = AttachmentMetadataModel.new(params[:attachable])
-    if @attachable_file.save
-      flash[:notice] = 'Attachment was successfully created.'
-      redirect_to attachable_url(@attachable_file)     
-    else
-      render :action => :new
-    end
-  end
-
-attachement_fu scripting
-====================================
-
-You may wish to import a large number of images or attachments. 
-The following example shows how to upload a file from a script. 
-
-#!/usr/bin/env ./script/runner
-
-# required to use ActionController::TestUploadedFile 
-require 'action_controller'
-require 'action_controller/test_process.rb'
-
-path = "./public/images/x.jpg"
-
-# mimetype is a string like "image/jpeg". One way to get the mimetype for a given file on a UNIX system
-# mimetype = `file -ib #{path}`.gsub(/\n/,"")
-
-mimetype = "image/jpeg"
-
-# This will "upload" the file at path and create the new model.
-@attachable = AttachmentMetadataModel.new(:uploaded_data => ActionController::TestUploadedFile.new(path, mimetype))
-@attachable.save

-Two methods are available to models: +has_attachment+ and
-+validates_as_attachment+.
-
-== has_attachment(options = {})
-
-This method accepts the options in a hash:
-
-[:content_type]
-    Allowed content types.
-
-    By default, all content types are allowed. Use +:image+ to allow all
-    standard image types.
-
-[:min_size]
-    Minimum file size.
-
-    By default, set to +1.byte+.
-
-[:max_size]
-    Maximum file size.
-
-    By default, set to +1.megabyte+.
-
-[:size]
-    Minimum and maximum file size.
-
-    By default, set to +1..1.megabyte+. Overrides +:min_size+ and
-    +:max_size+.
-
-[:resize_to]
-    Used by RMagick.
-
-    Tells RMagick how to resize images. Pass either an array specifying
-    width and height or a geometry string.  Prefixing the geometry string
-    with a 'c' will crop the image to the specified size.
-
-[:sharpen_on_resize]
-    Used by RMagick.
-
-    If set to true, images are sharpened after being resized.
-
-[:thumbnails]
-    A set of thumbnails to generate.
-
-    This accepts a hash of filename suffixes and RMagick resizing options. This
-    option need only be included if you want thumbnailing.
-
-    If you have a polymorphic parent relationship, you can provide
-    parent-type-specific thumbnail settings by using a pair with the type string
-    as key and a Hash of thumbnail definitions, or a method symbol, as value.
-    The method symbol will call the named method in order to get a
-    dynamically-built Hash of thumbnail definitions, which gives you full
-    flexibility. AttachmentFu automatically detects your first polymorphic
-    +belongs_to+ relationship.
-
-[:thumbnail_class]
-    Which model class to use for thumbnails.
-
-    By default, the current attachment class is used.
-
-[:jpeg_quality]
-    JPEG quality settings for thumbnail resizes.
-
-    Arguments can be in multiple formats:
-
-    * Integer from 0 (basically crap) to 100 (basically lossless, fat files).
-
-    * When relying on tdd-image_science, you can also use one of its +JPEG_xxx+
-      constants for predefined ratios/settings.
-
-    * You can also use a Hash, with keys being either  thumbnail symbols (I
-      repeat: _symbols_) or surface boundaries.  A surface boundary is a string
-      starting with either '<' or '>=', followed by a number of pixels.  This
-      lets you specify per-thumbnail or per-general-thumbnail-"size" JPEG
-      qualities. (which can be useful when you have a _lot_ of thumbnail
-      options). Surface example: <code>{'<2000' => 90, '>=2000' => 75}</code>.
-
-    Defaults vary depending on the processor (ImageScience: 100%,
-    Rmagick/MiniMagick/Gd2: 75%, CoreImage: auto-adjust). Note that only
-    tdd-image_science (available from GitHub) currently supports explicit JPEG
-    quality; the default image_science currently forces 100%.
-
-[:path_prefix]
-    Path to store the uploaded files in. Uses <code>public/#{table_name}</code>
-    by default for the filesystem, and just <code>#{table_name}</code> for the
-    S3 and Cloud Files backend. Setting this sets the +:storage+ to
-    +:file_system+.
-
-[:partition]
-    Whether to partiton files in directories like +/0000/0001/image.jpg+.
-    Default is true. Only applicable to the +:file_system+ backend.
-
-[:storage]
-    Specifies the storage system to use. Defaults to +:db_file+. Options are
-    +:file_system+, +:db_file+, +:s3+, and +:cloud_files+.
-
-[:cloudfront]
-    If using S3 for storage, this option allows for serving the files via Amazon
-    CloudFront. Defaults to false.
-
-[:processor]
-    Sets the image processor to use for resizing of the attached image. Options
-    include ImageScience, Rmagick, MiniMagick, Gd2 and CoreImage. Default is
-    whatever is installed.
-
-[:uuid_primary_key]
-    If your model's primary key is a 128-bit UUID in hexadecimal format, then
-    set this to true.
-
-[:association_options]
-    attachment_fu automatically defines associations with thumbnails with
-    +has_many+ and +belongs_to+. If there are any additional options that you
-    want to pass to these methods, then specify them here.
-
-Examples:
-
-    has_attachment(content_type: 'application/pdf')
-    has_attachment(
-        content_type: ['application/pdf', 'application/msword', 'text/plain']
-    )
-    has_attachment(content_type: ['application/pdf', :image], resize_to: 'x50')
-    has_attachment(content_type: :image, resize_to: [50,50])
-    has_attachment(max_size: 1.kilobyte)
-    has_attachment(size: 1.megabyte..2.megabytes)
-    has_attachment(storage: :cloud_files)
-    has_attachment(storage: :file_system, path_prefix: 'public/files')
-    has_attachment(
-        storage: :file_system,
-        path_prefix: 'public/files',
-        content_type: :image,
-        resize_to: [50, 50],
-        partition: false
-    )
-    has_attachment(
-        storage: :file_system,
-        path_prefix: 'public/files',
-        thumbnails: {thumb: [50, 50], geometry: 'x50'}
-    )
-    has_attachment(storage: :s3)
-    has_attachment(store: :s3, cloudfront: true)
-    has_attachment(thumbnails: {thumb: [50, 50], geometry: 'x50'})
-
-    # Let's say we have a polymorphic belongs_to, e.g. called 'imageable', where
-    # imageable_type (or whatever the :foreign_type option was set to) can be,
-    # among other things, 'Product', 'User' or 'Editorial', each of which should
-    # have extra thumbnails:
-
-    has_attachment(thumbnails: {
-        editorials: {fullsize: '150x100>'},
-        geometry: 'x50',
-        products: {large_thumb: '169x169!', zoomed: '500x500>'},
-        thumb: [50, 50],
-        users: {avatar: '64x64!'}
-    })
-
-    # JPEG qualities…
-
-    has_attachment(jpeg_quality: 75)
-    has_attachment(jpeg_quality: 80 | ImageScience::JPEG_PROGRESSIVE)
-    has_attachment(
-        thumbnails: {thumb: [50, 50], geometry: 'x50'},
-        jpeg_quality: {'<2000' => 90, '>=2000' => 75}
-    )
-    has_attachment(
-        thumbnails: {thumb: [50, 50], geometry: 'x50'},
-        jpeg_quality: {nil => 75, thumb: 90, geometry: 90}
-    )
-
-== validates_as_attachment
-
-This method prevents files outside of the valid range (+:min_size+ to
-+:max_size+, or the +:size+ range) from being saved. It does not however, halt
-the upload of such files. They will be uploaded into memory regardless of size
-before validation.
-
-To perform this validation, simply add +validates_as_attachment+ to your model.

-
-Field for attachment_fu +db_files+ table:
-
-    data, :binary # binary file data, for use in database file storage
-
-= attachment_fu views
-
-There are two main views tasks that will be directly affected by attachment_fu:
-upload forms and displaying uploaded images.
-
-There are two parts of the upload form that differ from typical usage.
-
-1. Include <code>multipart: true</code> in the html options of the +form_for+
-   tag. Example:
-
-        <%=
-        form_for(
-            :attachment_metadata,
-            url: {action: "create"},
-            html: {multipart: true}
-        ) do |form|
-        %>
-
-2. Use the +file_field+ helper with +:uploaded_data+ as the field name. Example:
-
-       <%= form.file_field(:uploaded_data) %>
-
-Displaying uploaded images is made easy by the +public_filename+ method of the
-ActiveRecord attachment objects using file system, s3, and Cloud Files storage.
-
-== public_filename(thumbnail = nil)
-
-Returns the public path to the file.  If a thumbnail prefix is specified it will
-return the public file path to the corresponding thumbnail.  Examples:
-
-    attachment_obj.public_filename         #=> /attachments/2/file.jpg
-    attachment_obj.public_filename(:thumb) #=> /attachments/2/file_thumb.jpg
-    attachment_obj.public_filename(:small) #=> /attachments/2/file_small.jpg
-
-When serving files from database storage, doing more than simply downloading the
-file is beyond the scope of this document.
-
-= attachment_fu controllers
-
-There are two considerations to take into account when using attachment_fu in
-controllers.
-
-The first is when the files have no publicly accessible path and need to be
-downloaded through an action. Example:
-
-    def readme
-        send_file(
-            '/path/to/readme.txt',
-            type: 'plain/text',
-            disposition: 'inline'
-        )
-    end
-
-See the possible values for +send_file+ for reference.
-
-The second is when saving the file when submitted from a form. Example:
-
-In a view:
-
-    <%= form.file_field(:attachable, :uploaded_data) %>
-
-In a controller:
-
-    def create
-        @attachable_file = AttachmentMetadataModel.new(params[:attachable])
-        if @attachable_file.save
-            flash[:notice] = 'Attachment was successfully created.'
-            redirect_to(attachable_url(@attachable_file))
-        else
-            redirect_to(action: 'new')
-        end
-    end
-
-= attachment_fu scripting
-
-You may wish to import a large number of images or attachments. The following
-example shows how to upload a file from a script.
-
-    #!/usr/bin/env ./script/runner
-
-    # required to use ActionController::TestUploadedFile
-    require 'action_controller'
-    require 'action_controller/test_process.rb'
-
-    path = "./public/images/x.jpg"
-
-    # `mimetype` is a string like "image/jpeg". One way to get the mimetype for
-    # a given file on a UNIX system: mimetype = `file -ib #{path}`.gsub(/\n/,"")
-    mimetype = "image/jpeg"
-
-    # This will "upload" the file at path and create the new model.
-    @attachable = AttachmentMetadataModel.new(
-        uploaded_data: ActionController::TestUploadedFile.new(path, mimetype)
-    )
-    @attachable.save

-      # Options:
-      # *  <tt>:content_type</tt> - Allowed content types.  Allows all by default.  Use :image to allow all standard image types.
-      # *  <tt>:min_size</tt> - Minimum size allowed.  1 byte is the default.
-      # *  <tt>:max_size</tt> - Maximum size allowed.  1.megabyte is the default.
-      # *  <tt>:size</tt> - Range of sizes allowed.  (1..1.megabyte) is the default.  This overrides the :min_size and :max_size options.
-      # *  <tt>:resize_to</tt> - Used by RMagick to resize images.  Pass either an array of width/height, or a geometry string.  Prefix geometry string with 'c' to crop image, ex. 'c100x100'
-      # *  <tt>:sharpen_on_resize</tt> - When using RMagick, setting to true will sharpen images after resizing.
-      # *  <tt>:jpeg_quality</tt> - Used to provide explicit JPEG quality for thumbnail/resize saves.  Can have multiple formats:
-      #      * Integer from 0 (basically crap) to 100 (basically lossless, fat files).
-      #      * When relying on ImageScience, you can also use one of its +JPEG_xxx+ constants for predefined ratios/settings.
-      #      * You can also use a Hash, with keys being either  thumbnail symbols (I repeat: _symbols_) or surface boundaries.
-      #        A surface boundary is a string starting with either '<' or '>=', followed by a number of pixels.  This lets you
-      #        specify per-thumbnail or per-general-thumbnail-"size" JPEG qualities. (which can be useful when you have a
-      #        _lot_ of thumbnail options).  Surface example:  +{ '<2000' => 90, '>=2000' => 75 }+.
-      #      Defaults vary depending on the processor (ImageScience: 100%, Rmagick/MiniMagick/Gd2: 75%,
-      #      CoreImage: auto-adjust). Note that only tdd-image_science (available from GitHub) currently supports explicit JPEG quality;
-      #      the default image_science currently forces 100%.
-      # *  <tt>:thumbnails</tt> - Specifies a set of thumbnails to generate.  This accepts a hash of filename suffixes and
-      #      RMagick resizing options.  If you have a polymorphic parent relationship, you can provide parent-type-specific
-      #      thumbnail settings by using a pair with the type string as key and a Hash of thumbnail definitions as value.
-      #      AttachmentFu automatically detects your first polymorphic +belongs_to+ relationship.
-      # *  <tt>:thumbnail_class</tt> - Set what class to use for thumbnails.  This attachment class is used by default.
-      # *  <tt>:path_prefix</tt> - path to store the uploaded files.  Uses public/#{table_name} by default for the filesystem, and just #{table_name}
-      #      for the S3 backend.  Setting this sets the :storage to :file_system.
-
-      # *  <tt>:storage</tt> - Use :file_system to specify the attachment data is stored with the file system.  Defaults to :db_system.
-      # *  <tt>:cloundfront</tt> - Set to true if you are using S3 storage and want to serve the files through CloudFront.  You will need to
-      #      set a distribution domain in the amazon_s3.yml config file. Defaults to false
-      # *  <tt>:bucket_key</tt> - Use this to specify a different bucket key other than :bucket_name in the amazon_s3.yml file.  This allows you to use
-      #      different buckets for different models. An example setting would be :image_bucket and the you would need to define the name of the corresponding
-      #      bucket in the amazon_s3.yml file.
-
-      # *  <tt>:keep_profile</tt> By default image EXIF data will be stripped to minimize image size. For small thumbnails this proivides important savings. Picture quality is not affected. Set to false if you want to keep the image profile as is. ImageScience will allways keep EXIF data.

-module Technoweenie # :nodoc:

-    module Backends
-      # = CloudFiles Storage Backend
-      #
-      # Enables use of {Rackspace Cloud Files}[http://www.mosso.com/cloudfiles.jsp] as a storage mechanism
-      #
-      # Based heavily on the Amazon S3 backend.
-      #
-      # == Requirements
-      #
-      # Requires the {Cloud Files Gem}[http://www.mosso.com/cloudfiles.jsp] by Rackspace
-      #
-      # == Configuration
-      #
-      # Configuration is done via <tt>Rails.root.to_s/config/rackspace_cloudfiles.yml</tt> and is loaded according to the <tt>#{Rails.env}</tt>.
-      # The minimum connection options that you must specify are a container name, your Mosso login name and your Mosso API key.
-      # You can sign up for Cloud Files and get access keys by visiting https://www.mosso.com/buy.htm
-      #
-      # Example configuration (Rails.root.to_s/config/rackspace_cloudfiles.yml)
-      #
-      #   development:
-      #     container_name: appname_development
-      #     username: <your key>
-      #     api_key: <your key>
-      #
-      #   test:
-      #     container_name: appname_test
-      #     username: <your key>
-      #     api_key: <your key>
-      #
-      #   production:
-      #     container_name: appname
-      #     username: <your key>
-      #     apik_key: <your key>
-      #
-      # You can change the location of the config path by passing a full path to the :cloudfiles_config_path option.
-      #
-      #   has_attachment :storage => :cloud_files, :cloudfiles_config_path => (Rails.root.to_s + '/config/mosso.yml')
-      #
-      # === Required configuration parameters
-      #
-      # * <tt>:username</tt> - The username for your Rackspace Cloud (Mosso) account. Provided by Rackspace.
-      # * <tt>:secret_access_key</tt> - The api key for your Rackspace Cloud account. Provided by Rackspace.
-      # * <tt>:container_name</tt> - The name of a container in your Cloud Files account.
-      #
-      # If any of these required arguments is missing, a AuthenticationException will be raised from CloudFiles::Connection.
-      #
-      # == Usage
-      #
-      # To specify Cloud Files as the storage mechanism for a model, set the acts_as_attachment <tt>:storage</tt> option to <tt>:cloud_files/tt>.
-      #
-      #   class Photo < ActiveRecord::Base
-      #     has_attachment :storage => :cloud_files
-      #   end
-      #
-      # === Customizing the path
-      #
-      # By default, files are prefixed using a pseudo hierarchy in the form of <tt>:table_name/:id</tt>, which results
-      # in Cloud Files object names (and urls) that look like: http://:server/:container_name/:table_name/:id/:filename with :table_name
-      # representing the customizable portion of the path. You can customize this prefix using the <tt>:path_prefix</tt>
-      # option:
-      #
-      #   class Photo < ActiveRecord::Base
-      #     has_attachment :storage => :cloud_files, :path_prefix => 'my/custom/path'
-      #   end
-      #
-      # Which would result in public URLs like <tt>http(s)://:server/:container_name/my/custom/path/:id/:filename.</tt>
-      #
-      # === Permissions
-      #
-      # File permisisons are determined by the permissions of the container.  At present, the options are public (and distributed
-      # by the Limelight CDN), and private (only available to your login)
-      #
-      # === Other options
-      #
-      # Of course, all the usual configuration options apply, such as content_type and thumbnails:
-      #
-      #   class Photo < ActiveRecord::Base
-      #     has_attachment :storage => :cloud_files, :content_type => ['application/pdf', :image], :resize_to => 'x50'
-      #     has_attachment :storage => :cloud_files, :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
-      #   end
-      #
-      # === Accessing Cloud Files URLs
-      #
-      # You can get an object's public URL using the cloudfiles_url accessor. For example, assuming that for your postcard app
-      # you had a container name like 'postcard_world_development', and an attachment model called Photo:
-      #
-      #   @postcard.cloudfiles_url # => http://cdn.cloudfiles.mosso.com/c45182/uploaded_files/20/london.jpg
-      #
-      # The resulting url is in the form: http://:server/:container_name/:table_name/:id/:file.
-      # The optional thumbnail argument will output the thumbnail's filename (if any).
-      #
-      # Additionally, you can get an object's base path relative to the container root using
-      # <tt>base_path</tt>:
-      #
-      #   @photo.file_base_path # => uploaded_files/20
-      #
-      # And the full path (including the filename) using <tt>full_filename</tt>:
-      #
-      #   @photo.full_filename # => uploaded_files/20/london.jpg
-      #
-      # Niether <tt>base_path</tt> or <tt>full_filename</tt> include the container name as part of the path.
-      # You can retrieve the container name using the <tt>container_name</tt> method.

-      # = AWS::S3 Storage Backend
-      #
-      # Enables use of {Amazon's Simple Storage Service}[http://aws.amazon.com/s3] as a storage mechanism
-      #
-      # == Requirements
-      #
-      # Requires the {AWS::S3 Library}[http://amazon.rubyforge.org] for S3 by Marcel Molina Jr. installed either
-      # as a gem or a as a Rails plugin.
-      #
-      # == Configuration
-      #
-      # Configuration is done via <tt>#{Rails.root}/config/amazon_s3.yml</tt> and is loaded according to the <tt>#{Rails.env}</tt>.
-      # The minimum connection options that you must specify are a bucket name, your access key id and your secret access key.
-      # If you don't already have your access keys, all you need to sign up for the S3 service is an account at Amazon.
-      # You can sign up for S3 and get access keys by visiting http://aws.amazon.com/s3.
-      #
-      # If you wish to use Amazon CloudFront to serve the files, you can also specify a distibution domain for the bucket.
-      # To read more about CloudFront, visit http://aws.amazon.com/cloudfront
-      #
-      # Example configuration (#{Rails.root}/config/amazon_s3.yml)
-      #
-      #   development:
-      #     bucket_name: appname_development
-      #     access_key_id: <your key>
-      #     secret_access_key: <your key>
-      #     distribution_domain: XXXX.cloudfront.net
-      #
-      #   test:
-      #     bucket_name: appname_test
-      #     access_key_id: <your key>
-      #     secret_access_key: <your key>
-      #     distribution_domain: XXXX.cloudfront.net
-      #
-      #   production:
-      #     bucket_name: appname
-      #     access_key_id: <your key>
-      #     secret_access_key: <your key>
-      #     distribution_domain: XXXX.cloudfront.net
-      #
-      # You can change the location of the config path by passing a full path to the :s3_config_path option.
-      #
-      #   has_attachment :storage => :s3, :s3_config_path => (#{Rails.root} + '/config/s3.yml')
-      #
-      # === Required configuration parameters
-      #
-      # * <tt>:access_key_id</tt> - The access key id for your S3 account. Provided by Amazon.
-      # * <tt>:secret_access_key</tt> - The secret access key for your S3 account. Provided by Amazon.
-      # * <tt>:bucket_name</tt> - A unique bucket name (think of the bucket_name as being like a database name).
-      #
-      # If any of these required arguments is missing, a MissingAccessKey exception will be raised from AWS::S3.
-      #
-      # == About bucket names
-      #
-      # Bucket names have to be globaly unique across the S3 system. And you can only have up to 100 of them,
-      # so it's a good idea to think of a bucket as being like a database, hence the correspondance in this
-      # implementation to the development, test, and production environments.
-      #
-      # The number of objects you can store in a bucket is, for all intents and purposes, unlimited.
-      #
-      # === Optional configuration parameters
-      #
-      # * <tt>:server</tt> - The server to make requests to. Defaults to <tt>s3.amazonaws.com</tt>.
-      # * <tt>:port</tt> - The port to the requests should be made on. Defaults to 80 or 443 if <tt>:use_ssl</tt> is set.
-      # * <tt>:use_ssl</tt> - If set to true, <tt>:port</tt> will be implicitly set to 443, unless specified otherwise. Defaults to false.
-      # * <tt>:distribution_domain</tt> - The CloudFront distribution domain for the bucket.  This can either be the assigned
-      #     distribution domain (ie. XXX.cloudfront.net) or a chosen domain using a CNAME. See CloudFront for more details.
-      #
-      # == Usage
-      #
-      # To specify S3 as the storage mechanism for a model, set the acts_as_attachment <tt>:storage</tt> option to <tt>:s3</tt>.
-      #
-      #   class Photo < ActiveRecord::Base
-      #     has_attachment :storage => :s3
-      #   end
-      #
-      # === Customizing the path
-      #
-      # By default, files are prefixed using a pseudo hierarchy in the form of <tt>:table_name/:id</tt>, which results
-      # in S3 urls that look like: http(s)://:server/:bucket_name/:table_name/:id/:filename with :table_name
-      # representing the customizable portion of the path. You can customize this prefix using the <tt>:path_prefix</tt>
-      # option:
-      #
-      #   class Photo < ActiveRecord::Base
-      #     has_attachment :storage => :s3, :path_prefix => 'my/custom/path'
-      #   end
-      #
-      # Which would result in URLs like <tt>http(s)://:server/:bucket_name/my/custom/path/:id/:filename.</tt>
-      #
-      # === Using different bucket names on different models
-      #
-      # By default the bucket name that the file will be stored to is the one specified by the
-      # <tt>:bucket_name</tt> key in the amazon_s3.yml file.  You can use the <tt>:bucket_key</tt> option
-      # to overide this behavior on a per model basis.  For instance if you want a bucket that will hold
-      # only Photos you can do this:
-      #
-      #   class Photo < ActiveRecord::Base
-      #     has_attachment :storage => :s3, :bucket_key => :photo_bucket_name
-      #   end
-      #
-      # And then your amazon_s3.yml file needs to look like this.
-      #
-      #   development:
-      #     bucket_name: appname_development
-      #     access_key_id: <your key>
-      #     secret_access_key: <your key>
-      #
-      #   test:
-      #     bucket_name: appname_test
-      #     access_key_id: <your key>
-      #     secret_access_key: <your key>
-      #
-      #   production:
-      #     bucket_name: appname
-      #     photo_bucket_name: appname_photos
-      #     access_key_id: <your key>
-      #     secret_access_key: <your key>
-      #
-      #  If the bucket_key you specify is not there in a certain environment then attachment_fu will
-      #  default to the <tt>bucket_name</tt> key.  This way you only have to create special buckets
-      #  this can be helpful if you only need special buckets in certain environments.
-      #
-      # === Permissions
-      #
-      # By default, files are stored on S3 with public access permissions. You can customize this using
-      # the <tt>:s3_access</tt> option to <tt>has_attachment</tt>. Available values are
-      # <tt>:private</tt>, <tt>:public_read_write</tt>, and <tt>:authenticated_read</tt>.
-      #
-      # === Other options
-      #
-      # Of course, all the usual configuration options apply, such as content_type and thumbnails:
-      #
-      #   class Photo < ActiveRecord::Base
-      #     has_attachment :storage => :s3, :content_type => ['application/pdf', :image], :resize_to => 'x50'
-      #     has_attachment :storage => :s3, :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
-      #   end
-      #
-      # === Accessing S3 URLs
-      #
-      # You can get an object's URL using the s3_url accessor. For example, assuming that for your postcard app
-      # you had a bucket name like 'postcard_world_development', and an attachment model called Photo:
-      #
-      #   @postcard.s3_url # => http(s)://s3.amazonaws.com/postcard_world_development/photos/1/mexico.jpg
-      #
-      # The resulting url is in the form: http(s)://:server/:bucket_name/:table_name/:id/:file.
-      # The optional thumbnail argument will output the thumbnail's filename (if any).
-      #
-      # Additionally, you can get an object's base path relative to the bucket root using
-      # <tt>base_path</tt>:
-      #
-      #   @photo.file_base_path # => photos/1
-      #
-      # And the full path (including the filename) using <tt>full_filename</tt>:
-      #
-      #   @photo.full_filename # => photos/
-      #
-      # Niether <tt>base_path</tt> or <tt>full_filename</tt> include the bucket name as part of the path.
-      # You can retrieve the bucket name using the <tt>bucket_name</tt> method.
-      #
-      # === Accessing CloudFront URLs
-      #
-      # You can get an object's CloudFront URL using the cloudfront_url accessor.  Using the example from above:
-      # @postcard.cloudfront_url # => http://XXXX.cloudfront.net/photos/1/mexico.jpg
-      #
-      # The resulting url is in the form: http://:distribution_domain/:table_name/:id/:file
-      #
-      # If you set :cloudfront to true in your model, the public_filename will be the CloudFront
-      # URL, not the S3 URL.

-# Generic image processor for scaling images based on CoreImage via RubyCocoa.
-#
-# Example usage:
-#
-# p = Processor.new OSX::CIImage.from(path_to_image)
-# p.resize(640, 480)
-# p.render do |result|
-#   result.save('resized.jpg', OSX::NSJPEGFileType)
-# end
-#
-# This will resize the image to the given dimensions exactly, if you'd like to ensure that aspect ratio is preserved:
-#
-# p = Processor.new OSX::CIImage.from(path_to_image)
-# p.fit(640)
-# p.render do |result|
-#   result.save('resized.jpg', OSX::NSJPEGFileType)
-# end
-#
-# fit(size) will attempt its best to resize the image so that the longest width/height (depending on image orientation) will match
-# the given size. The second axis will be calculated automatically based on the aspect ratio.
-#
-# Scaling is performed by first clamping the image so that its external bounds become infinite, this helps when scaling so that any
-# rounding discrepencies in dimensions don't affect the resultant image. We then perform a Lanczos transform on the image which scales
-# it to the target size. We then crop the image to the traget dimensions.
-#
-# If you are generating smaller images such as thumbnails where high quality rendering isn't as important, an additional method is
-# available:
-#
-# p = Processor.new OSX::CIImage.from(path_to_image)
-# p.thumbnail(100, 100)
-# p.render do |result|
-#   result.save('resized.jpg', OSX::NSJPEGFileType)
-# end
-#
-# This will perform a straight affine transform and scale the X and Y boundaries to the requested size. Generally, this will be faster
-# than a lanczos scale transform, but with a scaling quality trade.
-#
-# More than welcome to intregrate any patches, improvements - feel free to mail me with ideas.
-#
-# Thanks to
-# * Satoshi Nakagawa for working out that OCObjWrapper needs inclusion when aliasing method_missing on existing OSX::* classes.
-# * Vasantha Crabb for general help and inspiration with Cocoa
-# * Ben Schwarz for example image data and collaboration during performance testing

+attachment-fu
+=============
+
+attachment_fu is a plugin by Rick Olson (aka technoweenie <http://techno-weenie.net>) and is the successor to acts_as_attachment.  To get a basic run-through of its capabilities, check out Mike Clark's tutorial <http://clarkware.com/cgi/blosxom/2007/02/24#FileUploadFu>.
+
+
+attachment_fu functionality
+===========================
+
+attachment_fu facilitates file uploads in Ruby on Rails.  There are a few storage options for the actual file data, but the plugin always at a minimum stores metadata for each file in the database.
+
+There are four storage options for files uploaded through attachment_fu:
+  File system
+  Database file
+  Amazon S3
+  Rackspace (Mosso) Cloud Files
+
+Each method of storage many options associated with it that will be covered in the following section.  Something to note, however, is that the Amazon S3 storage requires you to modify config/amazon_s3.yml, the Rackspace Cloud Files storage requires you to modify config/rackspace_cloudfiles.yml, and the Database file storage requires an extra table.
+
+
+attachment_fu models
+====================
+
+For all three of these storage options a table of metadata is required.  This table will contain information about the file (hence the 'meta') and its location.  This table has no restrictions on naming, unlike the extra table required for database storage, which must have a table name of db_files (and by convention a model of DbFile).
+  
+In the model there are two methods made available by this plugins: has_attachment and validates_as_attachment.
+
+has_attachment(options = {})
+  This method accepts the options in a hash:
+    :content_type     # Allowed content types.
+                      # Allows all by default.  Use :image to allow all standard image types.
+    :min_size         # Minimum size allowed.
+                      # 1 byte is the default.
+    :max_size         # Maximum size allowed.
+                      # 1.megabyte is the default.
+    :size             # Range of sizes allowed.
+                      # (1..1.megabyte) is the default.  This overrides the :min_size and :max_size options.
+    :resize_to        # Used by RMagick to resize images.
+                      # Pass either an array of width/height, or a geometry string.
+    :thumbnails       # Specifies a set of thumbnails to generate.
+                      # This accepts a hash of filename suffixes and RMagick resizing options.
+                      # This option need only be included if you want thumbnailing.
+    :thumbnail_class  # Set which model class to use for thumbnails.
+                      # This current attachment class is used by default.
+    :path_prefix      # Path to store the uploaded files in.
+                      # Uses public/#{table_name} by default for the filesystem, and just #{table_name} for the S3 and Cloud Files backend.  
+                      # Setting this sets the :storage to :file_system.
+    :partition        # Whether to partiton files in directories like /0000/0001/image.jpg. Default is true. Only applicable to the :file_system backend.
+    :storage          # Specifies the storage system to use..
+                      # Defaults to :db_file.  Options are :file_system, :db_file, :s3, and :cloud_files.
+    :cloudfront       # If using S3 for storage, this option allows for serving the files via Amazon CloudFront.
+                      # Defaults to false.
+    :processor        # Sets the image processor to use for resizing of the attached image.
+                      # Options include ImageScience, Rmagick, and MiniMagick.  Default is whatever is installed.
+    :uuid_primary_key # If your model's primary key is a 128-bit UUID in hexadecimal format, then set this to true.
+    :association_options  # attachment_fu automatically defines associations with thumbnails with has_many and belongs_to. If there are any additional options that you want to pass to these methods, then specify them here.
+    
+
+  Examples:
+    has_attachment :max_size => 1.kilobyte
+    has_attachment :size => 1.megabyte..2.megabytes
+    has_attachment :content_type => 'application/pdf'
+    has_attachment :content_type => ['application/pdf', 'application/msword', 'text/plain']
+    has_attachment :content_type => :image, :resize_to => [50,50]
+    has_attachment :content_type => ['application/pdf', :image], :resize_to => 'x50'
+    has_attachment :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
+    has_attachment :storage => :file_system, :path_prefix => 'public/files'
+    has_attachment :storage => :file_system, :path_prefix => 'public/files', 
+                   :content_type => :image, :resize_to => [50,50], :partition => false
+    has_attachment :storage => :file_system, :path_prefix => 'public/files',
+                   :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
+    has_attachment :storage => :s3
+    has_attachment :store => :s3, :cloudfront => true
+    has_attachment :storage => :cloud_files
+
+validates_as_attachment
+  This method prevents files outside of the valid range (:min_size to :max_size, or the :size range) from being saved.  It does not however, halt the upload of such files.  They will be uploaded into memory regardless of size before validation.
+  
+  Example:
+    validates_as_attachment
+
+
+attachment_fu migrations
+========================
+
+Fields for attachment_fu metadata tables...
+  in general:
+    size,         :integer  # file size in bytes
+    content_type, :string   # mime type, ex: application/mp3
+    filename,     :string   # sanitized filename
+  that reference images:
+    height,       :integer  # in pixels
+    width,        :integer  # in pixels
+  that reference images that will be thumbnailed:
+    parent_id,    :integer  # id of parent image (on the same table, a self-referencing foreign-key).
+                            # Only populated if the current object is a thumbnail.
+    thumbnail,    :string   # the 'type' of thumbnail this attachment record describes.  
+                            # Only populated if the current object is a thumbnail.
+                            # Usage:
+                            # [ In Model 'Avatar' ]
+                            #   has_attachment :content_type => :image, 
+                            #                  :storage => :file_system, 
+                            #                  :max_size => 500.kilobytes,
+                            #                  :resize_to => '320x200>',
+                            #                  :thumbnails => { :small => '10x10>',
+                            #                                   :thumb => '100x100>' }
+                            # [ Elsewhere ]
+                            # @user.avatar.thumbnails.first.thumbnail #=> 'small'
+  that reference files stored in the database (:db_file):
+    db_file_id,   :integer  # id of the file in the database (foreign key)
+    
+Field for attachment_fu db_files table:
+  data, :binary # binary file data, for use in database file storage
+
+
+attachment_fu views
+===================
+
+There are two main views tasks that will be directly affected by attachment_fu: upload forms and displaying uploaded images.
+
+There are two parts of the upload form that differ from typical usage.
+  1. Include ':multipart => true' in the html options of the form_for tag.
+    Example:
+      <% form_for(:attachment_metadata, :url => { :action => "create" }, :html => { :multipart => true }) do |form| %>
+      
+  2. Use the file_field helper with :uploaded_data as the field name.
+    Example:
+      <%= form.file_field :uploaded_data %>
+
+Displaying uploaded images is made easy by the public_filename method of the ActiveRecord attachment objects using file system, s3, and Cloud Files storage.
+
+public_filename(thumbnail = nil)
+  Returns the public path to the file.  If a thumbnail prefix is specified it will return the public file path to the corresponding thumbnail.
+  Examples:
+    attachment_obj.public_filename          #=> /attachments/2/file.jpg
+    attachment_obj.public_filename(:thumb)  #=> /attachments/2/file_thumb.jpg
+    attachment_obj.public_filename(:small)  #=> /attachments/2/file_small.jpg
+
+When serving files from database storage, doing more than simply downloading the file is beyond the scope of this document.
+
+
+attachment_fu controllers
+=========================
+
+There are two considerations to take into account when using attachment_fu in controllers.
+
+The first is when the files have no publicly accessible path and need to be downloaded through an action.
+
+Example:
+  def readme
+    send_file '/path/to/readme.txt', :type => 'plain/text', :disposition => 'inline'
+  end
+  
+See the possible values for send_file for reference.
+
+
+The second is when saving the file when submitted from a form.
+Example in view:
+ <%= form.file_field :attachable, :uploaded_data %>
+
+Example in controller:
+  def create
+    @attachable_file = AttachmentMetadataModel.new(params[:attachable])
+    if @attachable_file.save
+      flash[:notice] = 'Attachment was successfully created.'
+      redirect_to attachable_url(@attachable_file)     
+    else
+      render :action => :new
+    end
+  end
+
+attachement_fu scripting
+====================================
+
+You may wish to import a large number of images or attachments. 
+The following example shows how to upload a file from a script. 
+
+#!/usr/bin/env ./script/runner
+
+# required to use ActionController::TestUploadedFile 
+require 'action_controller'
+require 'action_controller/test_process.rb'
+
+path = "./public/images/x.jpg"
+
+# mimetype is a string like "image/jpeg". One way to get the mimetype for a given file on a UNIX system
+# mimetype = `file -ib #{path}`.gsub(/\n/,"")
+
+mimetype = "image/jpeg"
+
+# This will "upload" the file at path and create the new model.
+@attachable = AttachmentMetadataModel.new(:uploaded_data => ActionController::TestUploadedFile.new(path, mimetype))
+@attachable.save

+requires you to modify +config/amazon_s3.yml+, the Rackspace Cloud Files storage
+requires you to modify +config/rackspace_cloudfiles.yml+, and the Database file
+storage requires an extra table.
+
+= attachment_fu models
+
+For all three of these storage options a table of metadata is required. This
+table will contain information about the file (hence the 'meta') and its
+location. This table has no restrictions on naming, unlike the extra table
+required for database storage, which must have a table name of +db_files+ (and
+by convention a model of +DbFile+).
+
+Two methods are available to models: +has_attachment+ and
++validates_as_attachment+.
+
+== has_attachment(options = {})
+
+This method accepts the options in a hash:
+
+[:content_type]
+    Allowed content types.
+
+    By default, all content types are allowed. Use +:image+ to allow all
+    standard image types.
+
+[:min_size]
+    Minimum file size.
+
+    By default, set to +1.byte+.
+
+[:max_size]
+    Maximum file size.
+
+    By default, set to +1.megabyte+.
+
+[:size]
+    Minimum and maximum file size.
+
+    By default, set to +1..1.megabyte+. Overrides +:min_size+ and
+    +:max_size+.
+
+[:resize_to]
+    Used by RMagick.
+
+    Tells RMagick how to resize images. Pass either an array specifying
+    width and height or a geometry string.  Prefixing the geometry string
+    with a 'c' will crop the image to the specified size.
+
+[:sharpen_on_resize]
+    Used by RMagick.
+
+    If set to true, images are sharpened after being resized.
+
+[:thumbnails]
+    A set of thumbnails to generate.
+
+    This accepts a hash of filename suffixes and RMagick resizing options. This
+    option need only be included if you want thumbnailing.
+
+    If you have a polymorphic parent relationship, you can provide
+    parent-type-specific thumbnail settings by using a pair with the type string
+    as key and a Hash of thumbnail definitions, or a method symbol, as value.
+    The method symbol will call the named method in order to get a
+    dynamically-built Hash of thumbnail definitions, which gives you full
+    flexibility. AttachmentFu automatically detects your first polymorphic
+    +belongs_to+ relationship.
+
+[:thumbnail_class]
+    Which model class to use for thumbnails.
+
+    By default, the current attachment class is used.
+
+[:jpeg_quality]
+    JPEG quality settings for thumbnail resizes.
+
+    Arguments can be in multiple formats:
+
+    * Integer from 0 (basically crap) to 100 (basically lossless, fat files).
+
+    * When relying on tdd-image_science, you can also use one of its +JPEG_xxx+
+      constants for predefined ratios/settings.
+
+    * You can also use a Hash, with keys being either  thumbnail symbols (I
+      repeat: _symbols_) or surface boundaries.  A surface boundary is a string
+      starting with either '<' or '>=', followed by a number of pixels.  This
+      lets you specify per-thumbnail or per-general-thumbnail-"size" JPEG
+      qualities. (which can be useful when you have a _lot_ of thumbnail
+      options). Surface example: <code>{'<2000' => 90, '>=2000' => 75}</code>.
+
+    Defaults vary depending on the processor (ImageScience: 100%,
+    Rmagick/MiniMagick/Gd2: 75%, CoreImage: auto-adjust). Note that only
+    tdd-image_science (available from GitHub) currently supports explicit JPEG
+    quality; the default image_science currently forces 100%.
+
+[:path_prefix]
+    Path to store the uploaded files in. Uses <code>public/#{table_name}</code>
+    by default for the filesystem, and just <code>#{table_name}</code> for the
+    S3 and Cloud Files backend. Setting this sets the +:storage+ to
+    +:file_system+.
+
+[:partition]
+    Whether to partiton files in directories like +/0000/0001/image.jpg+.
+    Default is true. Only applicable to the +:file_system+ backend.
+
+[:storage]
+    Specifies the storage system to use. Defaults to +:db_file+. Options are
+    +:file_system+, +:db_file+, +:s3+, and +:cloud_files+.
+
+[:cloudfront]
+    If using S3 for storage, this option allows for serving the files via Amazon
+    CloudFront. Defaults to false.
+
+[:processor]
+    Sets the image processor to use for resizing of the attached image. Options
+    include ImageScience, Rmagick, MiniMagick, Gd2 and CoreImage. Default is
+    whatever is installed.
+
+[:uuid_primary_key]
+    If your model's primary key is a 128-bit UUID in hexadecimal format, then
+    set this to true.
+
+[:association_options]
+    attachment_fu automatically defines associations with thumbnails with
+    +has_many+ and +belongs_to+. If there are any additional options that you
+    want to pass to these methods, then specify them here.
+
+Examples:
+
+    has_attachment(content_type: 'application/pdf')
+    has_attachment(
+        content_type: ['application/pdf', 'application/msword', 'text/plain']
+    )
+    has_attachment(content_type: ['application/pdf', :image], resize_to: 'x50')
+    has_attachment(content_type: :image, resize_to: [50,50])
+    has_attachment(max_size: 1.kilobyte)
+    has_attachment(size: 1.megabyte..2.megabytes)
+    has_attachment(storage: :cloud_files)
+    has_attachment(storage: :file_system, path_prefix: 'public/files')
+    has_attachment(
+        storage: :file_system,
+        path_prefix: 'public/files',
+        content_type: :image,
+        resize_to: [50, 50],
+        partition: false
+    )
+    has_attachment(
+        storage: :file_system,
+        path_prefix: 'public/files',
+        thumbnails: {thumb: [50, 50], geometry: 'x50'}
+    )
+    has_attachment(storage: :s3)
+    has_attachment(store: :s3, cloudfront: true)
+    has_attachment(thumbnails: {thumb: [50, 50], geometry: 'x50'})
+
+    # Let's say we have a polymorphic belongs_to, e.g. called 'imageable', where
+    # imageable_type (or whatever the :foreign_type option was set to) can be,
+    # among other things, 'Product', 'User' or 'Editorial', each of which should
+    # have extra thumbnails:
+
+    has_attachment(thumbnails: {
+        editorials: {fullsize: '150x100>'},
+        geometry: 'x50',
+        products: {large_thumb: '169x169!', zoomed: '500x500>'},
+        thumb: [50, 50],
+        users: {avatar: '64x64!'}
+    })
+
+    # JPEG qualities…
+
+    has_attachment(jpeg_quality: 75)
+    has_attachment(jpeg_quality: 80 | ImageScience::JPEG_PROGRESSIVE)
+    has_attachment(
+        thumbnails: {thumb: [50, 50], geometry: 'x50'},
+        jpeg_quality: {'<2000' => 90, '>=2000' => 75}
+    )
+    has_attachment(
+        thumbnails: {thumb: [50, 50], geometry: 'x50'},
+        jpeg_quality: {nil => 75, thumb: 90, geometry: 90}
+    )
+
+== validates_as_attachment
+
+This method prevents files outside of the valid range (+:min_size+ to
++:max_size+, or the +:size+ range) from being saved. It does not however, halt
+the upload of such files. They will be uploaded into memory regardless of size
+before validation.
+
+To perform this validation, simply add +validates_as_attachment+ to your model.

+
+Field for attachment_fu +db_files+ table:

+    data, :binary # binary file data, for use in database file storage
+
+= attachment_fu views
+
+There are two main views tasks that will be directly affected by attachment_fu:
+upload forms and displaying uploaded images.
+
+There are two parts of the upload form that differ from typical usage.
+
+1. Include <code>multipart: true</code> in the html options of the +form_for+
+   tag. Example:
+
+        <%=
+        form_for(
+            :attachment_metadata,
+            url: {action: "create"},
+            html: {multipart: true}
+        ) do |form|
+        %>
+
+2. Use the +file_field+ helper with +:uploaded_data+ as the field name. Example:
+
+       <%= form.file_field(:uploaded_data) %>
+
+Displaying uploaded images is made easy by the +public_filename+ method of the
+ActiveRecord attachment objects using file system, s3, and Cloud Files storage.
+
+== public_filename(thumbnail = nil)
+
+Returns the public path to the file.  If a thumbnail prefix is specified it will
+return the public file path to the corresponding thumbnail.  Examples:
+
+    attachment_obj.public_filename         #=> /attachments/2/file.jpg
+    attachment_obj.public_filename(:thumb) #=> /attachments/2/file_thumb.jpg
+    attachment_obj.public_filename(:small) #=> /attachments/2/file_small.jpg
+
+When serving files from database storage, doing more than simply downloading the
+file is beyond the scope of this document.
+
+= attachment_fu controllers
+
+There are two considerations to take into account when using attachment_fu in
+controllers.
+
+The first is when the files have no publicly accessible path and need to be
+downloaded through an action. Example:
+
+    def readme
+        send_file(
+            '/path/to/readme.txt',
+            type: 'plain/text',
+            disposition: 'inline'
+        )
+    end
+
+See the possible values for +send_file+ for reference.
+
+The second is when saving the file when submitted from a form. Example:
+
+In a view:
+
+    <%= form.file_field(:attachable, :uploaded_data) %>
+
+In a controller:
+
+    def create
+        @attachable_file = AttachmentMetadataModel.new(params[:attachable])
+        if @attachable_file.save
+            flash[:notice] = 'Attachment was successfully created.'
+            redirect_to(attachable_url(@attachable_file))
+        else
+            redirect_to(action: 'new')
+        end
+    end
+
+= attachment_fu scripting
+
+You may wish to import a large number of images or attachments. The following
+example shows how to upload a file from a script.
+
+    #!/usr/bin/env ./script/runner
+
+    # required to use ActionController::TestUploadedFile
+    require 'action_controller'
+    require 'action_controller/test_process.rb'
+
+    path = "./public/images/x.jpg"
+
+    # `mimetype` is a string like "image/jpeg". One way to get the mimetype for
+    # a given file on a UNIX system: mimetype = `file -ib #{path}`.gsub(/\n/,"")
+    mimetype = "image/jpeg"
+
+    # This will "upload" the file at path and create the new model.
+    @attachable = AttachmentMetadataModel.new(
+        uploaded_data: ActionController::TestUploadedFile.new(path, mimetype)
+    )
+    @attachable.save

+      # Options:
+      # *  <tt>:content_type</tt> - Allowed content types.  Allows all by default.  Use :image to allow all standard image types.
+      # *  <tt>:min_size</tt> - Minimum size allowed.  1 byte is the default.
+      # *  <tt>:max_size</tt> - Maximum size allowed.  1.megabyte is the default.
+      # *  <tt>:size</tt> - Range of sizes allowed.  (1..1.megabyte) is the default.  This overrides the :min_size and :max_size options.
+      # *  <tt>:resize_to</tt> - Used by RMagick to resize images.  Pass either an array of width/height, or a geometry string.  Prefix geometry string with 'c' to crop image, ex. 'c100x100'
+      # *  <tt>:sharpen_on_resize</tt> - When using RMagick, setting to true will sharpen images after resizing.
+      # *  <tt>:jpeg_quality</tt> - Used to provide explicit JPEG quality for thumbnail/resize saves.  Can have multiple formats:
+      #      * Integer from 0 (basically crap) to 100 (basically lossless, fat files).
+      #      * When relying on ImageScience, you can also use one of its +JPEG_xxx+ constants for predefined ratios/settings.
+      #      * You can also use a Hash, with keys being either  thumbnail symbols (I repeat: _symbols_) or surface boundaries.
+      #        A surface boundary is a string starting with either '<' or '>=', followed by a number of pixels.  This lets you
+      #        specify per-thumbnail or per-general-thumbnail-"size" JPEG qualities. (which can be useful when you have a
+      #        _lot_ of thumbnail options).  Surface example:  +{ '<2000' => 90, '>=2000' => 75 }+.
+      #      Defaults vary depending on the processor (ImageScience: 100%, Rmagick/MiniMagick/Gd2: 75%,
+      #      CoreImage: auto-adjust). Note that only tdd-image_science (available from GitHub) currently supports explicit JPEG quality;
+      #      the default image_science currently forces 100%.
+      # *  <tt>:thumbnails</tt> - Specifies a set of thumbnails to generate.  This accepts a hash of filename suffixes and
+      #      RMagick resizing options.  If you have a polymorphic parent relationship, you can provide parent-type-specific
+      #      thumbnail settings by using a pair with the type string as key and a Hash of thumbnail definitions as value.
+      #      AttachmentFu automatically detects your first polymorphic +belongs_to+ relationship.
+      # *  <tt>:thumbnail_class</tt> - Set what class to use for thumbnails.  This attachment class is used by default.
+      # *  <tt>:path_prefix</tt> - path to store the uploaded files.  Uses public/#{table_name} by default for the filesystem, and just #{table_name}
+      #      for the S3 backend.  Setting this sets the :storage to :file_system.
+
+      # *  <tt>:storage</tt> - Use :file_system to specify the attachment data is stored with the file system.  Defaults to :db_system.
+      # *  <tt>:cloundfront</tt> - Set to true if you are using S3 storage and want to serve the files through CloudFront.  You will need to
+      #      set a distribution domain in the amazon_s3.yml config file. Defaults to false
+      # *  <tt>:bucket_key</tt> - Use this to specify a different bucket key other than :bucket_name in the amazon_s3.yml file.  This allows you to use
+      #      different buckets for different models. An example setting would be :image_bucket and the you would need to define the name of the corresponding
+      #      bucket in the amazon_s3.yml file.
+
+      # *  <tt>:keep_profile</tt> By default image EXIF data will be stripped to minimize image size. For small thumbnails this proivides important savings. Picture quality is not affected. Set to false if you want to keep the image profile as is. ImageScience will allways keep EXIF data.

+      # = CloudFiles Storage Backend
+      #
+      # Enables use of {Rackspace Cloud Files}[http://www.mosso.com/cloudfiles.jsp] as a storage mechanism
+      #
+      # Based heavily on the Amazon S3 backend.
+      #
+      # == Requirements
+      #
+      # Requires the {Cloud Files Gem}[http://www.mosso.com/cloudfiles.jsp] by Rackspace
+      #
+      # == Configuration
+      #
+      # Configuration is done via <tt>Rails.root.to_s/config/rackspace_cloudfiles.yml</tt> and is loaded according to the <tt>#{Rails.env}</tt>.
+      # The minimum connection options that you must specify are a container name, your Mosso login name and your Mosso API key.
+      # You can sign up for Cloud Files and get access keys by visiting https://www.mosso.com/buy.htm
+      #
+      # Example configuration (Rails.root.to_s/config/rackspace_cloudfiles.yml)
+      #
+      #   development:
+      #     container_name: appname_development
+      #     username: <your key>
+      #     api_key: <your key>
+      #
+      #   test:
+      #     container_name: appname_test
+      #     username: <your key>
+      #     api_key: <your key>
+      #
+      #   production:
+      #     container_name: appname
+      #     username: <your key>
+      #     apik_key: <your key>
+      #
+      # You can change the location of the config path by passing a full path to the :cloudfiles_config_path option.
+      #
+      #   has_attachment :storage => :cloud_files, :cloudfiles_config_path => (Rails.root.to_s + '/config/mosso.yml')
+      #
+      # === Required configuration parameters
+      #
+      # * <tt>:username</tt> - The username for your Rackspace Cloud (Mosso) account. Provided by Rackspace.
+      # * <tt>:secret_access_key</tt> - The api key for your Rackspace Cloud account. Provided by Rackspace.
+      # * <tt>:container_name</tt> - The name of a container in your Cloud Files account.
+      #
+      # If any of these required arguments is missing, a AuthenticationException will be raised from CloudFiles::Connection.
+      #
+      # == Usage
+      #
+      # To specify Cloud Files as the storage mechanism for a model, set the acts_as_attachment <tt>:storage</tt> option to <tt>:cloud_files/tt>.
+      #
+      #   class Photo < ActiveRecord::Base
+      #     has_attachment :storage => :cloud_files
+      #   end
+      #
+      # === Customizing the path
+      #
+      # By default, files are prefixed using a pseudo hierarchy in the form of <tt>:table_name/:id</tt>, which results
+      # in Cloud Files object names (and urls) that look like: http://:server/:container_name/:table_name/:id/:filename with :table_name
+      # representing the customizable portion of the path. You can customize this prefix using the <tt>:path_prefix</tt>
+      # option:
+      #
+      #   class Photo < ActiveRecord::Base
+      #     has_attachment :storage => :cloud_files, :path_prefix => 'my/custom/path'
+      #   end
+      #
+      # Which would result in public URLs like <tt>http(s)://:server/:container_name/my/custom/path/:id/:filename.</tt>
+      #
+      # === Permissions
+      #
+      # File permisisons are determined by the permissions of the container.  At present, the options are public (and distributed
+      # by the Limelight CDN), and private (only available to your login)
+      #
+      # === Other options
+      #
+      # Of course, all the usual configuration options apply, such as content_type and thumbnails:
+      #
+      #   class Photo < ActiveRecord::Base
+      #     has_attachment :storage => :cloud_files, :content_type => ['application/pdf', :image], :resize_to => 'x50'
+      #     has_attachment :storage => :cloud_files, :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
+      #   end
+      #
+      # === Accessing Cloud Files URLs
+      #
+      # You can get an object's public URL using the cloudfiles_url accessor. For example, assuming that for your postcard app
+      # you had a container name like 'postcard_world_development', and an attachment model called Photo:
+      #
+      #   @postcard.cloudfiles_url # => http://cdn.cloudfiles.mosso.com/c45182/uploaded_files/20/london.jpg
+      #
+      # The resulting url is in the form: http://:server/:container_name/:table_name/:id/:file.
+      # The optional thumbnail argument will output the thumbnail's filename (if any).
+      #
+      # Additionally, you can get an object's base path relative to the container root using
+      # <tt>base_path</tt>:
+      #
+      #   @photo.file_base_path # => uploaded_files/20
+      #
+      # And the full path (including the filename) using <tt>full_filename</tt>:
+      #
+      #   @photo.full_filename # => uploaded_files/20/london.jpg
+      #
+      # Niether <tt>base_path</tt> or <tt>full_filename</tt> include the container name as part of the path.
+      # You can retrieve the container name using the <tt>container_name</tt> method.

+      # = AWS::S3 Storage Backend
+      #
+      # Enables use of {Amazon's Simple Storage Service}[http://aws.amazon.com/s3] as a storage mechanism
+      #
+      # == Requirements
+      #
+      # Requires the {AWS::S3 Library}[http://amazon.rubyforge.org] for S3 by Marcel Molina Jr. installed either
+      # as a gem or a as a Rails plugin.
+      #
+      # == Configuration
+      #
+      # Configuration is done via <tt>#{Rails.root}/config/amazon_s3.yml</tt> and is loaded according to the <tt>#{Rails.env}</tt>.
+      # The minimum connection options that you must specify are a bucket name, your access key id and your secret access key.
+      # If you don't already have your access keys, all you need to sign up for the S3 service is an account at Amazon.
+      # You can sign up for S3 and get access keys by visiting http://aws.amazon.com/s3.
+      #
+      # If you wish to use Amazon CloudFront to serve the files, you can also specify a distibution domain for the bucket.
+      # To read more about CloudFront, visit http://aws.amazon.com/cloudfront
+      #
+      # Example configuration (#{Rails.root}/config/amazon_s3.yml)
+      #
+      #   development:
+      #     bucket_name: appname_development
+      #     access_key_id: <your key>
+      #     secret_access_key: <your key>
+      #     distribution_domain: XXXX.cloudfront.net
+      #
+      #   test:
+      #     bucket_name: appname_test
+      #     access_key_id: <your key>
+      #     secret_access_key: <your key>
+      #     distribution_domain: XXXX.cloudfront.net
+      #
+      #   production:
+      #     bucket_name: appname
+      #     access_key_id: <your key>
+      #     secret_access_key: <your key>
+      #     distribution_domain: XXXX.cloudfront.net
+      #
+      # You can change the location of the config path by passing a full path to the :s3_config_path option.
+      #
+      #   has_attachment :storage => :s3, :s3_config_path => (#{Rails.root} + '/config/s3.yml')
+      #
+      # === Required configuration parameters
+      #
+      # * <tt>:access_key_id</tt> - The access key id for your S3 account. Provided by Amazon.
+      # * <tt>:secret_access_key</tt> - The secret access key for your S3 account. Provided by Amazon.
+      # * <tt>:bucket_name</tt> - A unique bucket name (think of the bucket_name as being like a database name).
+      #
+      # If any of these required arguments is missing, a MissingAccessKey exception will be raised from AWS::S3.
+      #
+      # == About bucket names
+      #
+      # Bucket names have to be globaly unique across the S3 system. And you can only have up to 100 of them,
+      # so it's a good idea to think of a bucket as being like a database, hence the correspondance in this
+      # implementation to the development, test, and production environments.
+      #
+      # The number of objects you can store in a bucket is, for all intents and purposes, unlimited.
+      #
+      # === Optional configuration parameters
+      #
+      # * <tt>:server</tt> - The server to make requests to. Defaults to <tt>s3.amazonaws.com</tt>.
+      # * <tt>:port</tt> - The port to the requests should be made on. Defaults to 80 or 443 if <tt>:use_ssl</tt> is set.
+      # * <tt>:use_ssl</tt> - If set to true, <tt>:port</tt> will be implicitly set to 443, unless specified otherwise. Defaults to false.
+      # * <tt>:distribution_domain</tt> - The CloudFront distribution domain for the bucket.  This can either be the assigned
+      #     distribution domain (ie. XXX.cloudfront.net) or a chosen domain using a CNAME. See CloudFront for more details.
+      #
+      # == Usage
+      #
+      # To specify S3 as the storage mechanism for a model, set the acts_as_attachment <tt>:storage</tt> option to <tt>:s3</tt>.
+      #
+      #   class Photo < ActiveRecord::Base
+      #     has_attachment :storage => :s3
+      #   end
+      #
+      # === Customizing the path
+      #
+      # By default, files are prefixed using a pseudo hierarchy in the form of <tt>:table_name/:id</tt>, which results
+      # in S3 urls that look like: http(s)://:server/:bucket_name/:table_name/:id/:filename with :table_name
+      # representing the customizable portion of the path. You can customize this prefix using the <tt>:path_prefix</tt>
+      # option:
+      #
+      #   class Photo < ActiveRecord::Base
+      #     has_attachment :storage => :s3, :path_prefix => 'my/custom/path'
+      #   end
+      #
+      # Which would result in URLs like <tt>http(s)://:server/:bucket_name/my/custom/path/:id/:filename.</tt>
+      #
+      # === Using different bucket names on different models
+      #
+      # By default the bucket name that the file will be stored to is the one specified by the
+      # <tt>:bucket_name</tt> key in the amazon_s3.yml file.  You can use the <tt>:bucket_key</tt> option
+      # to overide this behavior on a per model basis.  For instance if you want a bucket that will hold
+      # only Photos you can do this:
+      #
+      #   class Photo < ActiveRecord::Base
+      #     has_attachment :storage => :s3, :bucket_key => :photo_bucket_name
+      #   end
+      #
+      # And then your amazon_s3.yml file needs to look like this.
+      #
+      #   development:
+      #     bucket_name: appname_development
+      #     access_key_id: <your key>
+      #     secret_access_key: <your key>
+      #
+      #   test:
+      #     bucket_name: appname_test
+      #     access_key_id: <your key>
+      #     secret_access_key: <your key>
+      #
+      #   production:
+      #     bucket_name: appname
+      #     photo_bucket_name: appname_photos
+      #     access_key_id: <your key>
+      #     secret_access_key: <your key>
+      #
+      #  If the bucket_key you specify is not there in a certain environment then attachment_fu will
+      #  default to the <tt>bucket_name</tt> key.  This way you only have to create special buckets
+      #  this can be helpful if you only need special buckets in certain environments.
+      #
+      # === Permissions
+      #
+      # By default, files are stored on S3 with public access permissions. You can customize this using
+      # the <tt>:s3_access</tt> option to <tt>has_attachment</tt>. Available values are
+      # <tt>:private</tt>, <tt>:public_read_write</tt>, and <tt>:authenticated_read</tt>.
+      #
+      # === Other options
+      #
+      # Of course, all the usual configuration options apply, such as content_type and thumbnails:
+      #
+      #   class Photo < ActiveRecord::Base
+      #     has_attachment :storage => :s3, :content_type => ['application/pdf', :image], :resize_to => 'x50'
+      #     has_attachment :storage => :s3, :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
+      #   end
+      #
+      # === Accessing S3 URLs
+      #
+      # You can get an object's URL using the s3_url accessor. For example, assuming that for your postcard app
+      # you had a bucket name like 'postcard_world_development', and an attachment model called Photo:
+      #
+      #   @postcard.s3_url # => http(s)://s3.amazonaws.com/postcard_world_development/photos/1/mexico.jpg
+      #
+      # The resulting url is in the form: http(s)://:server/:bucket_name/:table_name/:id/:file.
+      # The optional thumbnail argument will output the thumbnail's filename (if any).
+      #
+      # Additionally, you can get an object's base path relative to the bucket root using
+      # <tt>base_path</tt>:
+      #
+      #   @photo.file_base_path # => photos/1
+      #
+      # And the full path (including the filename) using <tt>full_filename</tt>:
+      #
+      #   @photo.full_filename # => photos/
+      #
+      # Niether <tt>base_path</tt> or <tt>full_filename</tt> include the bucket name as part of the path.
+      # You can retrieve the bucket name using the <tt>bucket_name</tt> method.
+      #
+      # === Accessing CloudFront URLs
+      #
+      # You can get an object's CloudFront URL using the cloudfront_url accessor.  Using the example from above:
+      # @postcard.cloudfront_url # => http://XXXX.cloudfront.net/photos/1/mexico.jpg
+      #
+      # The resulting url is in the form: http://:distribution_domain/:table_name/:id/:file
+      #
+      # If you set :cloudfront to true in your model, the public_filename will be the CloudFront
+      # URL, not the S3 URL.

1	-attachment-fu
2	-=============
3	-
4	-attachment_fu is a plugin by Rick Olson (aka technoweenie <http://techno-weenie.net>) and is the successor to acts_as_attachment. To get a basic run-through of its capabilities, check out Mike Clark's tutorial <http://clarkware.com/cgi/blosxom/2007/02/24#FileUploadFu>.
5	-
6	-
7	-attachment_fu functionality
8	-===========================
9	-
10	-attachment_fu facilitates file uploads in Ruby on Rails. There are a few storage options for the actual file data, but the plugin always at a minimum stores metadata for each file in the database.
11	-
12	-There are four storage options for files uploaded through attachment_fu:
13	- File system
14	- Database file
15	- Amazon S3
16	- Rackspace (Mosso) Cloud Files
17	-
18	-Each method of storage many options associated with it that will be covered in the following section. Something to note, however, is that the Amazon S3 storage requires you to modify config/amazon_s3.yml, the Rackspace Cloud Files storage requires you to modify config/rackspace_cloudfiles.yml, and the Database file storage requires an extra table.
19	-
20	-
21	-attachment_fu models
22	-====================
23	-
24	-For all three of these storage options a table of metadata is required. This table will contain information about the file (hence the 'meta') and its location. This table has no restrictions on naming, unlike the extra table required for database storage, which must have a table name of db_files (and by convention a model of DbFile).
25	-
26	-In the model there are two methods made available by this plugins: has_attachment and validates_as_attachment.
27	-
28	-has_attachment(options = {})
29	- This method accepts the options in a hash:
30	- :content_type # Allowed content types.
31	- # Allows all by default. Use :image to allow all standard image types.
32	- :min_size # Minimum size allowed.
33	- # 1 byte is the default.
34	- :max_size # Maximum size allowed.
35	- # 1.megabyte is the default.
36	- :size # Range of sizes allowed.
37	- # (1..1.megabyte) is the default. This overrides the :min_size and :max_size options.
38	- :resize_to # Used by RMagick to resize images.
39	- # Pass either an array of width/height, or a geometry string.
40	- :thumbnails # Specifies a set of thumbnails to generate.
41	- # This accepts a hash of filename suffixes and RMagick resizing options.
42	- # This option need only be included if you want thumbnailing.
43	- :thumbnail_class # Set which model class to use for thumbnails.
44	- # This current attachment class is used by default.
45	- :path_prefix # Path to store the uploaded files in.
46	- # Uses public/#{table_name} by default for the filesystem, and just #{table_name} for the S3 and Cloud Files backend.
47	- # Setting this sets the :storage to :file_system.
48	- :partition # Whether to partiton files in directories like /0000/0001/image.jpg. Default is true. Only applicable to the :file_system backend.
49	- :storage # Specifies the storage system to use..
50	- # Defaults to :db_file. Options are :file_system, :db_file, :s3, and :cloud_files.
51	- :cloudfront # If using S3 for storage, this option allows for serving the files via Amazon CloudFront.
52	- # Defaults to false.
53	- :processor # Sets the image processor to use for resizing of the attached image.
54	- # Options include ImageScience, Rmagick, and MiniMagick. Default is whatever is installed.
55	- :uuid_primary_key # If your model's primary key is a 128-bit UUID in hexadecimal format, then set this to true.
56	- :association_options # attachment_fu automatically defines associations with thumbnails with has_many and belongs_to. If there are any additional options that you want to pass to these methods, then specify them here.
57	-
58	-
59	- Examples:
60	- has_attachment :max_size => 1.kilobyte
61	- has_attachment :size => 1.megabyte..2.megabytes
62	- has_attachment :content_type => 'application/pdf'
63	- has_attachment :content_type => ['application/pdf', 'application/msword', 'text/plain']
64	- has_attachment :content_type => :image, :resize_to => [50,50]
65	- has_attachment :content_type => ['application/pdf', :image], :resize_to => 'x50'
66	- has_attachment :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
67	- has_attachment :storage => :file_system, :path_prefix => 'public/files'
68	- has_attachment :storage => :file_system, :path_prefix => 'public/files',
69	- :content_type => :image, :resize_to => [50,50], :partition => false
70	- has_attachment :storage => :file_system, :path_prefix => 'public/files',
71	- :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
72	- has_attachment :storage => :s3
73	- has_attachment :store => :s3, :cloudfront => true
74	- has_attachment :storage => :cloud_files
75	-
76	-validates_as_attachment
77	- This method prevents files outside of the valid range (:min_size to :max_size, or the :size range) from being saved. It does not however, halt the upload of such files. They will be uploaded into memory regardless of size before validation.
78	-
79	- Example:
80	- validates_as_attachment
81	-
82	-
83	-attachment_fu migrations
84	-========================
85	-
86	-Fields for attachment_fu metadata tables...
87	- in general:
88	- size, :integer # file size in bytes
89	- content_type, :string # mime type, ex: application/mp3
90	- filename, :string # sanitized filename
91	- that reference images:
92	- height, :integer # in pixels
93	- width, :integer # in pixels
94	- that reference images that will be thumbnailed:
95	- parent_id, :integer # id of parent image (on the same table, a self-referencing foreign-key).
96	- # Only populated if the current object is a thumbnail.
97	- thumbnail, :string # the 'type' of thumbnail this attachment record describes.
98	- # Only populated if the current object is a thumbnail.
99	- # Usage:
100	- # [ In Model 'Avatar' ]
101	- # has_attachment :content_type => :image,
102	- # :storage => :file_system,
103	- # :max_size => 500.kilobytes,
104	- # :resize_to => '320x200>',
105	- # :thumbnails => { :small => '10x10>',
106	- # :thumb => '100x100>' }
107	- # [ Elsewhere ]
108	- # @user.avatar.thumbnails.first.thumbnail #=> 'small'
109	- that reference files stored in the database (:db_file):
110	- db_file_id, :integer # id of the file in the database (foreign key)
111	-
112	-Field for attachment_fu db_files table:
113	- data, :binary # binary file data, for use in database file storage
114	-
115	-
116	-attachment_fu views
117	-===================
118	-
119	-There are two main views tasks that will be directly affected by attachment_fu: upload forms and displaying uploaded images.
120	-
121	-There are two parts of the upload form that differ from typical usage.
122	- 1. Include ':multipart => true' in the html options of the form_for tag.
123	- Example:
124	- <% form_for(:attachment_metadata, :url => { :action => "create" }, :html => { :multipart => true }) do \|form\| %>
125	-
126	- 2. Use the file_field helper with :uploaded_data as the field name.
127	- Example:
128	- <%= form.file_field :uploaded_data %>
129	-
130	-Displaying uploaded images is made easy by the public_filename method of the ActiveRecord attachment objects using file system, s3, and Cloud Files storage.
131	-
132	-public_filename(thumbnail = nil)
133	- Returns the public path to the file. If a thumbnail prefix is specified it will return the public file path to the corresponding thumbnail.
134	- Examples:
135	- attachment_obj.public_filename #=> /attachments/2/file.jpg
136	- attachment_obj.public_filename(:thumb) #=> /attachments/2/file_thumb.jpg
137	- attachment_obj.public_filename(:small) #=> /attachments/2/file_small.jpg
138	-
139	-When serving files from database storage, doing more than simply downloading the file is beyond the scope of this document.
140	-
141	-
142	-attachment_fu controllers
143	-=========================
144	-
145	-There are two considerations to take into account when using attachment_fu in controllers.
146	-
147	-The first is when the files have no publicly accessible path and need to be downloaded through an action.
148	-
149	-Example:
150	- def readme
151	- send_file '/path/to/readme.txt', :type => 'plain/text', :disposition => 'inline'
152	- end
153	-
154	-See the possible values for send_file for reference.
155	-
156	-
157	-The second is when saving the file when submitted from a form.
158	-Example in view:
159	- <%= form.file_field :attachable, :uploaded_data %>
160	-
161	-Example in controller:
162	- def create
163	- @attachable_file = AttachmentMetadataModel.new(params[:attachable])
164	- if @attachable_file.save
165	- flash[:notice] = 'Attachment was successfully created.'
166	- redirect_to attachable_url(@attachable_file)
167	- else
168	- render :action => :new
169	- end
170	- end
171	-
172	-attachement_fu scripting
173	-====================================
174	-
175	-You may wish to import a large number of images or attachments.
176	-The following example shows how to upload a file from a script.
177	-
178	-#!/usr/bin/env ./script/runner
179	-
180	-# required to use ActionController::TestUploadedFile
181	-require 'action_controller'

187	-# mimetype = `file -ib #{path}`.gsub(/\n/,"")
188	-
189	-mimetype = "image/jpeg"
190	-
191	-# This will "upload" the file at path and create the new model.

41	-
42	-[:content_type]
43	- Allowed content types.
44	-
45	- By default, all content types are allowed. Use +:image+ to allow all
46	- standard image types.
47	-
48	-[:min_size]
49	- Minimum file size.
50	-
51	- By default, set to +1.byte+.
52	-
53	-[:max_size]
54	- Maximum file size.
55	-
56	- By default, set to +1.megabyte+.
57	-
58	-[:size]
59	- Minimum and maximum file size.
60	-
61	- By default, set to +1..1.megabyte+. Overrides +:min_size+ and
62	- +:max_size+.
63	-
64	-[:resize_to]
65	- Used by RMagick.
66	-
67	- Tells RMagick how to resize images. Pass either an array specifying
68	- width and height or a geometry string. Prefixing the geometry string
69	- with a 'c' will crop the image to the specified size.
70	-
71	-[:sharpen_on_resize]
72	- Used by RMagick.
73	-
74	- If set to true, images are sharpened after being resized.
75	-
76	-[:thumbnails]
77	- A set of thumbnails to generate.
78	-
79	- This accepts a hash of filename suffixes and RMagick resizing options. This
80	- option need only be included if you want thumbnailing.
81	-
82	- If you have a polymorphic parent relationship, you can provide
83	- parent-type-specific thumbnail settings by using a pair with the type string
84	- as key and a Hash of thumbnail definitions, or a method symbol, as value.
85	- The method symbol will call the named method in order to get a
86	- dynamically-built Hash of thumbnail definitions, which gives you full
87	- flexibility. AttachmentFu automatically detects your first polymorphic
88	- +belongs_to+ relationship.
89	-
90	-[:thumbnail_class]
91	- Which model class to use for thumbnails.
92	-
93	- By default, the current attachment class is used.
94	-
95	-[:jpeg_quality]
96	- JPEG quality settings for thumbnail resizes.
97	-
98	- Arguments can be in multiple formats:
99	-
100	- * Integer from 0 (basically crap) to 100 (basically lossless, fat files).
101	-
102	- * When relying on tdd-image_science, you can also use one of its +JPEG_xxx+
103	- constants for predefined ratios/settings.
104	-
105	- * You can also use a Hash, with keys being either thumbnail symbols (I
106	- repeat: _symbols_) or surface boundaries. A surface boundary is a string
107	- starting with either '<' or '>=', followed by a number of pixels. This
108	- lets you specify per-thumbnail or per-general-thumbnail-"size" JPEG
109	- qualities. (which can be useful when you have a _lot_ of thumbnail
110	- options). Surface example: <code>{'<2000' => 90, '>=2000' => 75}</code>.
111	-
112	- Defaults vary depending on the processor (ImageScience: 100%,
113	- Rmagick/MiniMagick/Gd2: 75%, CoreImage: auto-adjust). Note that only
114	- tdd-image_science (available from GitHub) currently supports explicit JPEG
115	- quality; the default image_science currently forces 100%.
116	-
117	-[:path_prefix]
118	- Path to store the uploaded files in. Uses <code>public/#{table_name}</code>
119	- by default for the filesystem, and just <code>#{table_name}</code> for the
120	- S3 and Cloud Files backend. Setting this sets the +:storage+ to
121	- +:file_system+.
122	-
123	-[:partition]
124	- Whether to partiton files in directories like +/0000/0001/image.jpg+.
125	- Default is true. Only applicable to the +:file_system+ backend.
126	-
127	-[:storage]
128	- Specifies the storage system to use. Defaults to +:db_file+. Options are
129	- +:file_system+, +:db_file+, +:s3+, and +:cloud_files+.
130	-
131	-[:cloudfront]
132	- If using S3 for storage, this option allows for serving the files via Amazon
133	- CloudFront. Defaults to false.
134	-
135	-[:processor]
136	- Sets the image processor to use for resizing of the attached image. Options
137	- include ImageScience, Rmagick, MiniMagick, Gd2 and CoreImage. Default is
138	- whatever is installed.
139	-
140	-[:uuid_primary_key]
141	- If your model's primary key is a 128-bit UUID in hexadecimal format, then
142	- set this to true.
143	-
144	-[:association_options]
145	- attachment_fu automatically defines associations with thumbnails with
146	- +has_many+ and +belongs_to+. If there are any additional options that you
147	- want to pass to these methods, then specify them here.
148	-
149	-Examples:
150	-
151	- has_attachment(content_type: 'application/pdf')
152	- has_attachment(
153	- content_type: ['application/pdf', 'application/msword', 'text/plain']
154	- )
155	- has_attachment(content_type: ['application/pdf', :image], resize_to: 'x50')
156	- has_attachment(content_type: :image, resize_to: [50,50])
157	- has_attachment(max_size: 1.kilobyte)

204	-

206	-+:max_size+, or the +:size+ range) from being saved. It does not however, halt
207	-the upload of such files. They will be uploaded into memory regardless of size
208	-before validation.

214	-Fields for attachment_fu metadata tables…
215	-
216	-In general:
217	-
218	- size, :integer # file size in bytes
219	- content_type, :string # mime type, ex: application/mp3
220	- filename, :string # sanitized filename
221	-
222	-That reference images:
223	-
224	- height, :integer # in pixels
225	- width, :integer # in pixels
226	-
227	-That reference images that will be thumbnailed:
228	-
229	- parent_id, :integer # id of parent image (on the same table, a
230	- # self-referencing foreign-key). Only populated if
231	- # the current object is a thumbnail.
232	- thumbnail, :string # The type of thumbnail this attachment record
233	- # describes. Only populated if the current object is
234	- # a thumbnail. Example:
235	- #
236	- # (In Model 'Avatar')
237	- # has_attachment(
238	- # :content_type => :image,
239	- # :storage => :file_system,
240	- # :max_size => 500.kilobytes,
241	- # :resize_to => '320x200>',
242	- # :thumbnails => {
243	- # :small => '10x10>',
244	- # :thumb => '100x100>'
245	- # }
246	- # )
247	- #
248	- # (Elsewhere)
249	- # @user.avatar.thumbnails.first.thumbnail # => 'small'
250	- #
251	- db_file_id, :integer # ID of the file in the database (foreign key) that
252	- # reference files stored in the database (:db_file).
253	-
254	-Field for attachment_fu +db_files+ table:
255	-
256	- data, :binary # binary file data, for use in database file storage
257	-
258	-= attachment_fu views
259	-
260	-There are two main views tasks that will be directly affected by attachment_fu:
261	-upload forms and displaying uploaded images.
262	-
263	-There are two parts of the upload form that differ from typical usage.
264	-
265	-1. Include <code>multipart: true</code> in the html options of the +form_for+
266	- tag. Example:
267	-
268	- <%=
269	- form_for(
270	- :attachment_metadata,
271	- url: {action: "create"},
272	- html: {multipart: true}
273	- ) do \|form\|
274	- %>
275	-
276	-2. Use the +file_field+ helper with +:uploaded_data+ as the field name. Example:
277	-
278	- <%= form.file_field(:uploaded_data) %>
279	-
280	-Displaying uploaded images is made easy by the +public_filename+ method of the
281	-ActiveRecord attachment objects using file system, s3, and Cloud Files storage.
282	-
283	-== public_filename(thumbnail = nil)
284	-
285	-Returns the public path to the file. If a thumbnail prefix is specified it will
286	-return the public file path to the corresponding thumbnail. Examples:
287	-
288	- attachment_obj.public_filename #=> /attachments/2/file.jpg
289	- attachment_obj.public_filename(:thumb) #=> /attachments/2/file_thumb.jpg
290	- attachment_obj.public_filename(:small) #=> /attachments/2/file_small.jpg
291	-
292	-When serving files from database storage, doing more than simply downloading the
293	-file is beyond the scope of this document.
294	-
295	-= attachment_fu controllers
296	-
297	-There are two considerations to take into account when using attachment_fu in
298	-controllers.
299	-
300	-The first is when the files have no publicly accessible path and need to be
301	-downloaded through an action. Example:
302	-
303	- def readme
304	- send_file(
305	- '/path/to/readme.txt',
306	- type: 'plain/text',
307	- disposition: 'inline'
308	- )
309	- end
310	-
311	-See the possible values for +send_file+ for reference.
312	-
313	-The second is when saving the file when submitted from a form. Example:
314	-
315	-In a view:
316	-
317	- <%= form.file_field(:attachable, :uploaded_data) %>
318	-
319	-In a controller:
320	-
321	- def create
322	- @attachable_file = AttachmentMetadataModel.new(params[:attachable])
323	- if @attachable_file.save
324	- flash[:notice] = 'Attachment was successfully created.'
325	- redirect_to(attachable_url(@attachable_file))
326	- else
327	- redirect_to(action: 'new')
328	- end
329	- end
330	-
331	-= attachment_fu scripting
332	-
333	-You may wish to import a large number of images or attachments. The following
334	-example shows how to upload a file from a script.
335	-
336	- #!/usr/bin/env ./script/runner
337	-
338	- # required to use ActionController::TestUploadedFile
339	- require 'action_controller'
340	- require 'action_controller/test_process.rb'
341	-
342	- path = "./public/images/x.jpg"
343	-
344	- # `mimetype` is a string like "image/jpeg". One way to get the mimetype for
345	- # a given file on a UNIX system: mimetype = `file -ib #{path}`.gsub(/\n/,"")
346	- mimetype = "image/jpeg"
347	-
348	- # This will "upload" the file at path and create the new model.
349	- @attachable = AttachmentMetadataModel.new(
350	- uploaded_data: ActionController::TestUploadedFile.new(path, mimetype)
351	- )
352	- @attachable.save
