+# Version 0.8
+
+* Fixed a small bug on optional belongs to with namespaced controllers.
+* Allow a parameter to be given to collection_url in polymorphic cases to replace
+  the parent.
+* Allow InheritedResources to be called without inheritance.
+* Ensure that controllers that inherit from a controller with InheritedResources
+  works properly.
+
+# Version 0.7
+
+* Allow procs as default value in has scope to be able to use values from session, for example.
+* Allow blocks with arity 0 or -1 to be given as the redirect url:
+
+    def destroy
+      destroy!{ project_url(@project) }
+    end
+
+* Allow interpolation_options to be set in the application controller.
+* Added has_scope to controller (an interface for named_scopes).
+* Added polymorphic_belongs_to, optional_belongs_to and singleton_belongs_to
+  as quick methods.
+* Only load belongs_to, singleton and polymorphic helpers if they are actually
+  required. base_helpers, class_methods, dumb_responder and url_helpers are loaded
+  when you inherited from base for the first time.
+
+# Version 0.6
+
+* Ensure that the default template is not rendered if the default_template_format
+  is not accepted. This is somehow related with the security breach report:
+
+  http://www.rorsecurity.info/journal/2009/4/24/hidden-actions-render-templates.html
+
+  IR forbids based on mime types. For example: respond_to :html, :except => :index
+  ensures that the index.html.erb view is not rendered, making your IR controllers
+  safer.
+
+* Fixed a bug that happens only when format.xml is given to blocks and then it
+  acts as default, instead of format.html.
+* Fixed a strange bug where when you have create.html.erb or update.html.erb,
+  it makes IE6 and IE7 return unprocessable entity (because they send Mime::ALL).
+* Stop rescueing any error when constantizing the resource class and allow
+  route_prefix to be nil.
+* Cleaned up tests and responder structure. Whenever you pass a block to aliases
+  and this block responds to the request, the other blocks are not parsed improving performance.
+* [BACKWARDS INCOMPATIBLE] By default, Inherited Resources respond only :html requests.
+* Added a quick way to overwrite the redirect to url in :create, :update and :destroy.
+
+# Version 0.5
+
+* Decoupled routes name from :instance_name and :collection_name. This way we
+  have more flexibility. Use route_instance_name and route_collection_name to
+  to change routes.
+* Avoid calling human_name on nil when a resource class is not defined.
+* Only call I18n if it's defined.
+
+# Version 0.4
+
+* Dealing with namespaced controllers out of the box.
+* Added support to namespaced routes through :route_prefix.
+* Added fix when resource_url is not defined.
+* Added better handling for namespaced controllers.
+* Added flash messages scoped by namespaced controllers.
+* Deprecated {{resource}} in I18n, use {{resource_name}} instead.
+* rspec bug fix is not automatically required anymore. User has to do it
+  explicitly.
+* Added a file which fix a rspec bug when render is called inside a method
+  which receives a block.
+* parent? does not take begin_of_association_chain into account anymore
+* Added options to url helpers.
+* Added :optional to belongs_to associations. It allows you to deal with
+  categories/1/products/2 and /products/2 with just one controller.
+* Cleaned up tests.
+
+# Version 0.3
+
+* Minor bump after three bug fixes.
+* Bug fix when showing warning of constant redefinition.
+* Bug fix with ApplicationController not being unloaded properly on development.
+* Bug fix when having root singleton resources. Calling collection_url would
+  raise "NoMethodError _url", not it will call root_url.
+* More comments on UrlHelpers.
+
+# Version 0.2
+
+* Bug fix when ApplicationController is already loaded when we load respond_to.
+* Added support success/failure blocks.
+* Eager loading of files to work properly in multithreaded environments.
+
+# Version 0.1
+
+* Added more helper_methods.
+* Added Rails 2.3.0 and changed tests to work with ActionController::TestCase.
+* First release. Support to I18n, singleton controllers, polymorphic
+controllers, belongs_to, nested_belongs_to and url helpers.

+Inherited Resources
+License: MIT
+Version: 0.8.5
+
+You can also read this README in pretty html at the GitHub project Wiki page:
+
+  http://wiki.github.com/josevalim/inherited_resources
+
+Description
+-----------
+
+Inherited Resources speeds up development by making your controllers inherit
+all restful actions so you just have to focus on what is important. It makes
+your controllers more powerful and cleaner at the same time.
+
+Plus, making your controllers follow a pattern, it helps you to write better
+code by following fat models and skinny controllers convention.
+
+Inherited Resources is tested and compatible with Rails 2.2.x and Rails 2.3.x.
+
+keywords: resources, controller, singleton, belongs_to, polymorphic, named_scope and I18n
+
+Installation
+------------
+
+Install Inherited Resources is very easy. It is stored in GitHub, so just run
+the following:
+
+   gem sources -a http://gems.github.com
+   sudo gem install josevalim-inherited_resources
+
+If you want it as plugin, just do:
+
+   script/plugin install git://github.com/josevalim/inherited_resources.git
+
+rspec-rails <= 1.1.12 known bug
+-------------------------------
+
+InheritedResources has a known bug with rspec-rails. Please upgrade your rspec
+version or use the fix which ships with InheritedResources:
+
+  require 'inherited_resources/spec'
+
+Basic Usage
+-----------
+
+To use Inherited Resources you just have to inherit (duh) it:
+
+   class ProjectsController < InheritedResources::Base
+   end
+
+And all actions are defined and working, check it! Your projects collection
+(in the index action) is still available in the instance variable @projects
+and your project resource (all other actions) is available as @ project.
+
+The next step is to define which mime types this controller provides:
+
+   class ProjectsController < InheritedResources::Base
+     respond_to :html, :xml, :json
+   end
+
+You can also specify them based per action:
+
+   class ProjectsController < InheritedResources::Base
+     respond_to :html, :xml, :json
+     respond_to :js, :only => :create
+     respond_to :iphone, :except => [ :edit, :update ]
+   end
+
+For each request, it first checkes if the "controller/action.format" file is
+available (for example "projects/create.xml") and if it's not, it checks if
+the resource respond to :to_format (in this case, :to_xml). Otherwise returns 404.
+
+Another option is to specify which actions the controller will inherit from
+the InheritedResources::Base:
+
+   class ProjectsController < InheritedResources::Base
+     actions :index, :show, :new, :create
+   end
+
+Or:
+
+   class ProjectsController < InheritedResources::Base
+     actions :all, :except => [ :edit, :update, :destroy ]
+   end
+
+In your views, you will get the following helpers:
+
+   resource        #=> @project
+   collection      #=> @projects
+   resource_class  #=> Project
+
+As you might expect, collection (@projects instance variable) is only available
+on index actions.
+
+If for some reason you cannot inherit from InheritedResources::Base, you can
+call inherit_resources or resource_controller in your controller class scope:
+
+  class AccountsController < ApplicationController
+    inherit_resources # or resource_controller
+  end
+
+Overwriting defaults
+--------------------
+
+Whenever you inherit from InheritedResources, several defaults are assumed.
+For example you can have an AccountsController to account management while the
+resource is an User:
+
+   class AccountsController < InheritedResources::Base
+     defaults :resource_class => User, :collection_name, 'users', :instance_name => 'user'
+   end
+
+In the case above, in your views you will have @users and @user variables, but
+the routes used will still be accounts_url and account_url. If you plan also to
+change the routes, you can use :route_collection_name and :route_instance_name.
+
+Namespaced controllers work out of the box, but if you need to specify a
+different route prefix, you can do the following:
+
+   class Administrators::PeopleController < InheritedResources::Base
+     defaults :route_prefix => 'admin'
+   end
+
+Then your named routes will be: 'admin_people_url', 'admin_person_url' instead
+of 'administrators_people_url' and 'administrators_person_url'.
+
+If you want to customize how resources are retrieved you can overwrite
+collection and resource methods. The first is called on index action and the
+second on all other actions. Let's suppose you want to add pagination to your
+projects collection:
+
+   class ProjectsController < InheritedResources::Base
+     protected
+       def collection
+         @projects ||= end_of_association_chain.paginate(params[:page]).all
+       end
+   end
+
+The end_of_association_chain returns your resource after nesting all associations
+and scopes (more about this below).
+
+InheritedResources also introduces another method called begin_of_association_chain.
+It's mostly used when you want to create resources based on the @current_user and
+you have urls like "account/projects". In such cases, you have to do
+@current_user.projects.find or @current_user.projects.build in your actions.
+
+You can deal with it just doing:
+
+   class ProjectsController < InheritedResources::Base
+     protected
+       def begin_of_association_chain
+         @current_user
+       end
+   end
+
+Overwriting actions
+-------------------
+
+Let's suppose that after destroying a project you want to redirect to your
+root url instead of redirecting to projects url. You just have to do:
+
+   class ProjectsController < InheritedResources::Base
+     def destroy
+       super do |format|
+         format.html { redirect_to root_url }
+       end
+     end
+   end
+
+You are opening your action and giving the parent action a new behavior. No
+tricks, no DSL, just Ruby.
+
+On the other hand, I have to agree that calling super is not very readable.
+That's why all methods have aliases. So this is equivalent:
+
+   class ProjectsController < InheritedResources::Base
+     def destroy
+       destroy! do |format|
+         format.html { redirect_to root_url }
+       end
+     end
+   end
+
+Even more, since most of the times when you change a create, update or destroy
+action is because you want to to change to where it redirects, a shortcut is
+provided. So you can do:
+
+   class ProjectsController < InheritedResources::Base
+     def destroy
+       destroy!{ root_url }
+     end
+   end
+
+Now let's suppose that before create a project you have to do something special
+but you don't want to create a before filter for it:
+
+   class ProjectsController < InheritedResources::Base
+     def create
+       @project = Project.new(params[:project])
+       @project.something_special!
+       create!
+     end
+   end
+
+Yes, that simple! The nice part is since you already set the instance variable
+@project, it will not build a project again.
+
+Before we finish this topic, we should talk about one more thing: "success/failure
+blocks". Let's suppose that when we update our project, in case of failure, we
+want to redirect to the project url instead of re-rendering the edit template.
+
+Our first attempt to do this would be:
+
+   class ProjectsController < InheritedResources::Base
+     def update
+       update! do |format|
+         unless @project.errors.empty? # failure
+           format.html { redirect_to project_url(@project) }
+         end
+       end
+     end
+   end
+
+Looks to verbose, right? We can actually do:
+
+   class ProjectsController < InheritedResources::Base
+     def update
+       update! do |success, failure|
+         failure.html { redirect_to project_url(@project) }
+       end
+     end
+   end
+
+Much better! So explaining everything: when you give a block which expects one
+argument it will be executed in both scenarios: success and failure. But If you
+give a block that expects two arguments, the first will be executed only in
+success scenarios and the second in failure scenarios. You keep everything
+clean and organized inside the same action.
+
+Flash messages and I18n
+-----------------------
+
+Flash messages are powered by I18n api. It checks for messages in the following
+order:
+
+   flash.controller_name.action_name.status
+   flash.actions.action_name.status
+
+If none is available, a default message in english set. In a create action
+on projects controller, it will search for:
+
+   flash.projects.create.status
+   flash.actions.create.status
+
+The status can be :notice (when the object can be created, updated
+or destroyed with success) or :error (when the objecy cannot be created
+or updated).
+
+Those messages are interpolated by using the resource class human name, which 
+is also localized and it means you can set:
+
+   flash:
+     actions:
+       create:
+         notice: "Hooray! {{resource_name}} was successfully created!"
+
+It will replace {{resource_name}} by the human name of the resource class,
+which is "Project" in this case.
+
+But sometimes, flash messages are not that simple. Sometimes you want to say
+the title of the project while updating a project. Well, that's easy also:
+
+   flash:
+     projects:
+       update:
+         notice: "Hooray! The project "{{project_title}}" was updated!"
+
+Since :project_title is not available for interpolation by default, you have
+to overwrite interpolation_options.
+
+   def interpolation_options
+     { :project_title => @project.title }
+   end
+
+Then you will finally have:
+
+   "Hooray! The project "Plataforma" was updated!"
+
+By default, resource name is capitalized. If you want to make it lower case, you
+can add to your application controller:
+
+   def interpolation_options
+     { :resource_name => resource_class.human_name.downcase }
+  end
+
+Finally, if your controller is namespaced, for example Admin::ProjectsController,
+the messages will be checked in the following order:
+
+   flash.admin.projects.create.notice
+   flash.admin.actions.create.notice
+   flash.projects.create.notice
+   flash.actions.create.notice
+
+Has Scope
+---------
+
+InheritedResources tries to integrate nicely with your model. In order to do so,
+it also is named_scope fluent. Let's suppose our Project model with the scopes:
+
+  class ProjectsController < ActiveRecord::Base
+    named_scope :featured, :conditions => { :featured => true }
+    named_scope :by_methodology, proc {|methodology| { :conditions => { :methodology => methodology } } }
+    named_scope :limit, proc{|limit| :limit => limit.to_i }
+  end
+
+Your controller:
+
+  class ProjectsController < InheritedResources::Base
+    has_scope :featured, :boolean => true, :only => :index
+    has_scope :by_methodology
+    has_scope :limit, :default => 10
+  end
+
+Then for each request:
+
+  /projects
+  #=> acts like a normal request, but returning 10 projects
+
+  /projects?featured=true
+  #=> calls the featured named scope and bring 10 featured projects
+
+  /projects?featured=true&by_methodology=agile&limit=20
+  #=> brings 20 featured projects with methodology agile
+
+You can retrieve the current scopes in use with :current_scopes method.
+In the last case, it would return:
+
+  { :featured => "true", :by_methodology => "agile", :limit => "20" }
+
+Finally, let's suppose you store on the session how many projects the user sees
+per page. In such cases, you can give a proc as default value:
+
+   has_scope :limit, :default => proc{|c| c.session[:limit] || 10 }
+
+Belongs to
+----------
+
+Finally, our Projects are going to get some Tasks. Then you create a
+TasksController and do:
+
+   class TasksController < InheritedResources::Base
+     belongs_to :project
+   end
+
+belongs_to accepts several options to be able to configure the association.
+For example, if you want urls like /projects/:project_title/tasks, you can
+customize how InheritedResources find your projects:
+
+   class TasksController < InheritedResources::Base
+     belongs_to :project, :finder => :find_by_title!, :param => :project_title
+   end
+
+It also accepts :route_name, :parent_class and :instance_name as options.
+Check the lib/inherited_resources/class_methods.rb for more.
+
+Nested belongs to
+-----------------
+
+Now, our Tasks get some Comments and you need to nest even deeper. Good
+practices says that you should never nest more than two resources, but sometimes
+you have to for security reasons. So this is an example of how you can do it:
+
+   class CommentsController < InheritedResources::Base
+     nested_belongs_to :project, :task
+   end
+
+If you need to configure any of these belongs to, you can nested them using blocks:
+
+   class CommentsController < InheritedResources::Base
+     belongs_to :project, :finder => :find_by_title!, :param => :project_title do
+       belongs_to :task
+     end
+   end
+
+Warning: calling several belongs_to is the same as nesting them:
+
+   class CommentsConroller < InheritedResources::Base
+     belongs_to :project
+     belongs_to :task
+   end
+
+In other words, the code above is the same as calling nested_belongs_to.
+
+Polymorphic belongs to
+----------------------
+
+We can go even further. Let's suppose our Projects can now have Files, Messages
+and Tasks, and they are all commentable. In this case, the best solution is to
+use polymorphism:
+
+   class CommentsController < InheritedResources::Base
+     belongs_to :task, :file, :message, :polymorphic => true
+     # polymorphic_belongs_to :task, :file, :message
+   end
+
+You can even use it with nested resources:
+
+   class CommentsController < InheritedResources::Base
+     belongs_to :project do
+       belongs_to :task, :file, :message, :polymorphic => true
+     end
+   end
+
+The url in such cases can be:
+
+   /project/1/task/13/comments
+   /project/1/file/11/comments
+   /project/1/message/9/comments
+
+When using polymorphic associations, you get some free helpers:
+
+   parent?         #=> true
+   parent_type     #=> :task
+   parent_class    #=> Task
+   parent          #=> @task
+
+Optional belongs to
+-------------------
+
+Later you decide to create a view to show all comments, independent if they belong
+to a task, file or message. You can reuse your polymorphic controller just doing:
+
+  class ProjectsController < InheritedResources::Base
+    belongs_to :task, :file, :message, :optional => true
+    # optional_belongs_to :task, :file, :message
+  end
+
+This will handle all those urls properly:

+
+This is treated as a special type of polymorphic associations, thus all helpers
+are available. As you expect, when no parent is found, the helpers return:
+
+   parent?         #=> false
+   parent_type     #=> nil
+   parent_class    #=> nil
+   parent          #=> nil
+
+Singletons
+----------
+
+Now we are going to add manager to projects. We say that Manager is a singleton
+resource because a Project has just one manager. You should declare it as
+has_one (or resource) in your routes.
+
+To declare an association as singleton, you just have to give the :singleton
+option.
+
+   class ManagersController < InheritedResources::Base
+     belongs_to :project, :singleton => true
+     # singleton_belongs_to :project
+   end
+
+It will deal with everything again and hide the action :index from you.
+
+URL Helpers
+-----------
+
+When you use InheritedResources it creates some URL helpers.
+And they handle everything for you. :)
+
+   # /posts/1/comments
+   resource_url               # => /posts/1/comments/#{@comment.to_param}
+   resource_url(comment)      # => /posts/1/comments/#{comment.to_param}
+   new_resource_url           # => /posts/1/comments/new
+   edit_resource_url          # => /posts/1/comments/#{@comment.to_param}/edit
+   edit_resource_url(comment) #=>  /posts/1/comments/#{comment.to_param}/edit
+   collection_url             # => /posts/1/comments
+
+   # /projects/1/tasks
+   resource_url               # => /projects/1/tasks/#{@task.to_param}
+   resource_url(task)         # => /projects/1/tasks/#{task.to_param}
+   new_resource_url           # => /projects/1/tasks/new
+   edit_resource_url          # => /projects/1/tasks/#{@task.to_param}/edit
+   edit_resource_url(task)    # => /projects/1/tasks/#{task.to_param}/edit
+   collection_url             # => /projects/1/tasks
+
+   # /users
+   resource_url               # => /users/#{@user.to_param}
+   resource_url(user)         # => /users/#{user.to_param}
+   new_resource_url           # => /users/new
+   edit_resource_url          # => /users/#{@user.to_param}/edit
+   edit_resource_url(user)    # => /users/#{user.to_param}/edit
+   collection_url             # => /users
+
+Those urls helpers also accepts a hash as options, just as in named routes.
+
+   # /projects/1/tasks
+   collection_url(:page => 1, :limit => 10) #=> /projects/1/tasks?page=1&limit=10
+
+Another nice thing is that those urls are not guessed during runtime. They are
+all created when your application is loaded (except for polymorphic
+associations, that relies on Rails polymorphic_url).

+  # = polymorphic associations
+  #
+  # In some cases you have a resource that belongs to two different resources
+  # but not at the same time. For example, let's suppose you have File, Message
+  # and Task as resources and they are all commentable.
+  #
+  # Polymorphic associations allows you to create just one controller that will
+  # deal with each case.
+  #
+  #   class Comment < InheritedResources::Base
+  #     belongs_to :file, :message, :task, :polymorphic => true
+  #   end
+  #
+  # Your routes should be something like:
+  #
+  #   m.resources :files,    :has_many => :comments #=> /files/13/comments
+  #   m.resources :tasks,    :has_many => :comments #=> /tasks/17/comments
+  #   m.resources :messages, :has_many => :comments #=> /messages/11/comments
+  #
+  # When using polymorphic associations, you get some free helpers:
+  #
+  #   parent?         #=> true
+  #   parent_type     #=> :task
+  #   parent_class    #=> Task
+  #   parent          #=> @task
+  #
+  # This polymorphic controllers thing is a great idea by James Golick and he
+  # built it in resource_controller. Here is just a re-implementation.
+  #
+  # = optional polymorphic associations
+  #
+  # Let's take another break from ProjectsController. Let's suppose we are
+  # building a store, which sell products.
+  #
+  # On the website, we can show all products, but also products scoped to
+  # categories, brands, users. In this case case, the association is optional, and
+  # we deal with it in the following way:
+  #
+  #   class ProductsController < InheritedResources::Base
+  #     belongs_to :category, :brand, :user, :polymorphic => true, :optional => true
+  #   end
+  #
+  # This will handle all those urls properly:
+  #
+  #   /products/1
+  #   /categories/2/products/5
+  #   /brands/10/products/3
+  #   /user/13/products/11
+  #
+  # = nested polymorphic associations
+  #
+  # You can have polymorphic associations with nested resources. Let's suppose
+  # that our File, Task and Message resources in the previous example belongs to
+  # a project.
+  #
+  # This way we can have:
+  #
+  #   class CommentsController < InheritedResources::Base
+  #     belongs_to :project {
+  #       belongs_to :file, :message, :task, :polymorphic => true
+  #     }

+  #
+  #   class CommentsController < InheritedResources::Base
+  #     nested_belongs_to :project
+  #     nested_belongs_to :file, :message, :task, :polymorphic => true
+  #   end
+  #
+  # Choose the syntax that makes more sense to you. :)
+  #
+  # Finally your routes should be something like:
+  #
+  #   map.resources :projects do |m|
+  #     m.resources :files,    :has_many => :comments #=> /projects/1/files/13/comments
+  #     m.resources :tasks,    :has_many => :comments #=> /projects/1/tasks/17/comments
+  #     m.resources :messages, :has_many => :comments #=> /projects/1/messages/11/comments

	1	+# Version 0.8
	2	+
	3	+* Fixed a small bug on optional belongs to with namespaced controllers.
	4	+* Allow a parameter to be given to collection_url in polymorphic cases to replace
	5	+ the parent.
	6	+* Allow InheritedResources to be called without inheritance.
	7	+* Ensure that controllers that inherit from a controller with InheritedResources
	8	+ works properly.
	9	+
	10	+# Version 0.7
	11	+
	12	+* Allow procs as default value in has scope to be able to use values from session, for example.
	13	+* Allow blocks with arity 0 or -1 to be given as the redirect url:
	14	+
	15	+ def destroy
	16	+ destroy!{ project_url(@project) }
	17	+ end
	18	+
	19	+* Allow interpolation_options to be set in the application controller.
	20	+* Added has_scope to controller (an interface for named_scopes).
	21	+* Added polymorphic_belongs_to, optional_belongs_to and singleton_belongs_to
	22	+ as quick methods.
	23	+* Only load belongs_to, singleton and polymorphic helpers if they are actually
	24	+ required. base_helpers, class_methods, dumb_responder and url_helpers are loaded
	25	+ when you inherited from base for the first time.
	26	+
	27	+# Version 0.6
	28	+
	29	+* Ensure that the default template is not rendered if the default_template_format
	30	+ is not accepted. This is somehow related with the security breach report:
	31	+
	32	+ http://www.rorsecurity.info/journal/2009/4/24/hidden-actions-render-templates.html
	33	+
	34	+ IR forbids based on mime types. For example: respond_to :html, :except => :index
	35	+ ensures that the index.html.erb view is not rendered, making your IR controllers
	36	+ safer.
	37	+
	38	+* Fixed a bug that happens only when format.xml is given to blocks and then it
	39	+ acts as default, instead of format.html.
	40	+* Fixed a strange bug where when you have create.html.erb or update.html.erb,
	41	+ it makes IE6 and IE7 return unprocessable entity (because they send Mime::ALL).
	42	+* Stop rescueing any error when constantizing the resource class and allow
	43	+ route_prefix to be nil.
	44	+* Cleaned up tests and responder structure. Whenever you pass a block to aliases
	45	+ and this block responds to the request, the other blocks are not parsed improving performance.
	46	+* [BACKWARDS INCOMPATIBLE] By default, Inherited Resources respond only :html requests.
	47	+* Added a quick way to overwrite the redirect to url in :create, :update and :destroy.
	48	+
	49	+# Version 0.5
	50	+
	51	+* Decoupled routes name from :instance_name and :collection_name. This way we
	52	+ have more flexibility. Use route_instance_name and route_collection_name to
	53	+ to change routes.
	54	+* Avoid calling human_name on nil when a resource class is not defined.
	55	+* Only call I18n if it's defined.
	56	+
	57	+# Version 0.4
	58	+
	59	+* Dealing with namespaced controllers out of the box.
	60	+* Added support to namespaced routes through :route_prefix.
	61	+* Added fix when resource_url is not defined.
	62	+* Added better handling for namespaced controllers.
	63	+* Added flash messages scoped by namespaced controllers.
	64	+* Deprecated {{resource}} in I18n, use {{resource_name}} instead.
	65	+* rspec bug fix is not automatically required anymore. User has to do it
	66	+ explicitly.
	67	+* Added a file which fix a rspec bug when render is called inside a method
	68	+ which receives a block.
	69	+* parent? does not take begin_of_association_chain into account anymore
	70	+* Added options to url helpers.
	71	+* Added :optional to belongs_to associations. It allows you to deal with
	72	+ categories/1/products/2 and /products/2 with just one controller.
	73	+* Cleaned up tests.
	74	+
	75	+# Version 0.3
	76	+
	77	+* Minor bump after three bug fixes.
	78	+* Bug fix when showing warning of constant redefinition.
	79	+* Bug fix with ApplicationController not being unloaded properly on development.
	80	+* Bug fix when having root singleton resources. Calling collection_url would
	81	+ raise "NoMethodError _url", not it will call root_url.
	82	+* More comments on UrlHelpers.
	83	+
	84	+# Version 0.2
	85	+
	86	+* Bug fix when ApplicationController is already loaded when we load respond_to.
	87	+* Added support success/failure blocks.
	88	+* Eager loading of files to work properly in multithreaded environments.
	89	+
	90	+# Version 0.1
	91	+
	92	+* Added more helper_methods.
	93	+* Added Rails 2.3.0 and changed tests to work with ActionController::TestCase.
	94	+* First release. Support to I18n, singleton controllers, polymorphic
	95	+controllers, belongs_to, nested_belongs_to and url helpers.

	16	+Plus, making your controllers follow a pattern, it helps you to write better
	17	+code by following fat models and skinny controllers convention.
	18	+
	19	+Inherited Resources is tested and compatible with Rails 2.2.x and Rails 2.3.x.

	21	+keywords: resources, controller, singleton, belongs_to, polymorphic, named_scope and I18n
	22	+
	23	+Installation
	24	+------------
	25	+
	26	+Install Inherited Resources is very easy. It is stored in GitHub, so just run
	27	+the following:
	28	+
	29	+ gem sources -a http://gems.github.com
	30	+ sudo gem install josevalim-inherited_resources
	31	+
	32	+If you want it as plugin, just do:
	33	+
	34	+ script/plugin install git://github.com/josevalim/inherited_resources.git
	35	+
	36	+rspec-rails <= 1.1.12 known bug
	37	+-------------------------------
	38	+
	39	+InheritedResources has a known bug with rspec-rails. Please upgrade your rspec
	40	+version or use the fix which ships with InheritedResources:
	41	+
	42	+ require 'inherited_resources/spec'
	43	+
	44	+Basic Usage
	45	+-----------
	46	+
	47	+To use Inherited Resources you just have to inherit (duh) it:
	48	+
	49	+ class ProjectsController < InheritedResources::Base
	50	+ end
	51	+
	52	+And all actions are defined and working, check it! Your projects collection
	53	+(in the index action) is still available in the instance variable @projects
	54	+and your project resource (all other actions) is available as @ project.
	55	+
	56	+The next step is to define which mime types this controller provides:
	57	+
	58	+ class ProjectsController < InheritedResources::Base
	59	+ respond_to :html, :xml, :json
	60	+ end
	61	+
	62	+You can also specify them based per action:
	63	+
	64	+ class ProjectsController < InheritedResources::Base
	65	+ respond_to :html, :xml, :json
	66	+ respond_to :js, :only => :create
	67	+ respond_to :iphone, :except => [ :edit, :update ]
	68	+ end
	69	+
	70	+For each request, it first checkes if the "controller/action.format" file is
	71	+available (for example "projects/create.xml") and if it's not, it checks if
	72	+the resource respond to :to_format (in this case, :to_xml). Otherwise returns 404.
	73	+
	74	+Another option is to specify which actions the controller will inherit from
	75	+the InheritedResources::Base:
	76	+
	77	+ class ProjectsController < InheritedResources::Base
	78	+ actions :index, :show, :new, :create
	79	+ end
	80	+
	81	+Or:
	82	+
	83	+ class ProjectsController < InheritedResources::Base
	84	+ actions :all, :except => [ :edit, :update, :destroy ]
	85	+ end
	86	+
	87	+In your views, you will get the following helpers:
	88	+
	89	+ resource #=> @project
	90	+ collection #=> @projects
	91	+ resource_class #=> Project
	92	+
	93	+As you might expect, collection (@projects instance variable) is only available
	94	+on index actions.
	95	+
	96	+If for some reason you cannot inherit from InheritedResources::Base, you can
	97	+call inherit_resources or resource_controller in your controller class scope:
	98	+
	99	+ class AccountsController < ApplicationController
	100	+ inherit_resources # or resource_controller
	101	+ end
	102	+
	103	+Overwriting defaults
	104	+--------------------
	105	+
	106	+Whenever you inherit from InheritedResources, several defaults are assumed.
	107	+For example you can have an AccountsController to account management while the
	108	+resource is an User:
	109	+
	110	+ class AccountsController < InheritedResources::Base
	111	+ defaults :resource_class => User, :collection_name, 'users', :instance_name => 'user'
	112	+ end
	113	+
	114	+In the case above, in your views you will have @users and @user variables, but
	115	+the routes used will still be accounts_url and account_url. If you plan also to
	116	+change the routes, you can use :route_collection_name and :route_instance_name.
	117	+
	118	+Namespaced controllers work out of the box, but if you need to specify a
	119	+different route prefix, you can do the following:
	120	+
	121	+ class Administrators::PeopleController < InheritedResources::Base
	122	+ defaults :route_prefix => 'admin'
	123	+ end
	124	+
	125	+Then your named routes will be: 'admin_people_url', 'admin_person_url' instead
	126	+of 'administrators_people_url' and 'administrators_person_url'.
	127	+
	128	+If you want to customize how resources are retrieved you can overwrite
	129	+collection and resource methods. The first is called on index action and the
	130	+second on all other actions. Let's suppose you want to add pagination to your
	131	+projects collection:
	132	+
	133	+ class ProjectsController < InheritedResources::Base
	134	+ protected
	135	+ def collection
	136	+ @projects \|\|= end_of_association_chain.paginate(params[:page]).all
	137	+ end
	138	+ end
	139	+
	140	+The end_of_association_chain returns your resource after nesting all associations
	141	+and scopes (more about this below).
	142	+
	143	+InheritedResources also introduces another method called begin_of_association_chain.
	144	+It's mostly used when you want to create resources based on the @current_user and
	145	+you have urls like "account/projects". In such cases, you have to do
	146	+@current_user.projects.find or @current_user.projects.build in your actions.
	147	+
	148	+You can deal with it just doing:
	149	+
	150	+ class ProjectsController < InheritedResources::Base
	151	+ protected
	152	+ def begin_of_association_chain
	153	+ @current_user
	154	+ end
	155	+ end
	156	+
	157	+Overwriting actions
	158	+-------------------
	159	+
	160	+Let's suppose that after destroying a project you want to redirect to your
	161	+root url instead of redirecting to projects url. You just have to do:
	162	+
	163	+ class ProjectsController < InheritedResources::Base
	164	+ def destroy
	165	+ super do \|format\|
	166	+ format.html { redirect_to root_url }
	167	+ end
	168	+ end
	169	+ end
	170	+
	171	+You are opening your action and giving the parent action a new behavior. No
	172	+tricks, no DSL, just Ruby.
	173	+
	174	+On the other hand, I have to agree that calling super is not very readable.
	175	+That's why all methods have aliases. So this is equivalent:
	176	+
	177	+ class ProjectsController < InheritedResources::Base
	178	+ def destroy
	179	+ destroy! do \|format\|
	180	+ format.html { redirect_to root_url }
	181	+ end
	182	+ end
	183	+ end
	184	+
	185	+Even more, since most of the times when you change a create, update or destroy
	186	+action is because you want to to change to where it redirects, a shortcut is
	187	+provided. So you can do:
	188	+
	189	+ class ProjectsController < InheritedResources::Base
	190	+ def destroy
	191	+ destroy!{ root_url }
	192	+ end
	193	+ end
	194	+
	195	+Now let's suppose that before create a project you have to do something special
	196	+but you don't want to create a before filter for it:
	197	+
	198	+ class ProjectsController < InheritedResources::Base
	199	+ def create
	200	+ @project = Project.new(params[:project])
	201	+ @project.something_special!
	202	+ create!
	203	+ end
	204	+ end
	205	+
	206	+Yes, that simple! The nice part is since you already set the instance variable
	207	+@project, it will not build a project again.
	208	+
	209	+Before we finish this topic, we should talk about one more thing: "success/failure
	210	+blocks". Let's suppose that when we update our project, in case of failure, we
	211	+want to redirect to the project url instead of re-rendering the edit template.
	212	+
	213	+Our first attempt to do this would be:
	214	+
	215	+ class ProjectsController < InheritedResources::Base
	216	+ def update
	217	+ update! do \|format\|
	218	+ unless @project.errors.empty? # failure
	219	+ format.html { redirect_to project_url(@project) }
	220	+ end
	221	+ end
	222	+ end
	223	+ end
	224	+
	225	+Looks to verbose, right? We can actually do:
	226	+
	227	+ class ProjectsController < InheritedResources::Base
	228	+ def update
	229	+ update! do \|success, failure\|
	230	+ failure.html { redirect_to project_url(@project) }
	231	+ end
	232	+ end
	233	+ end
	234	+
	235	+Much better! So explaining everything: when you give a block which expects one
	236	+argument it will be executed in both scenarios: success and failure. But If you
	237	+give a block that expects two arguments, the first will be executed only in
	238	+success scenarios and the second in failure scenarios. You keep everything
	239	+clean and organized inside the same action.
	240	+
	241	+Flash messages and I18n
	242	+-----------------------
	243	+
	244	+Flash messages are powered by I18n api. It checks for messages in the following
	245	+order:
	246	+
	247	+ flash.controller_name.action_name.status
	248	+ flash.actions.action_name.status
	249	+
	250	+If none is available, a default message in english set. In a create action
	251	+on projects controller, it will search for:
	252	+
	253	+ flash.projects.create.status
	254	+ flash.actions.create.status
	255	+
	256	+The status can be :notice (when the object can be created, updated
	257	+or destroyed with success) or :error (when the objecy cannot be created
	258	+or updated).
	259	+
	260	+Those messages are interpolated by using the resource class human name, which
	261	+is also localized and it means you can set:
	262	+
	263	+ flash:
	264	+ actions:
	265	+ create:
	266	+ notice: "Hooray! {{resource_name}} was successfully created!"
	267	+
	268	+It will replace {{resource_name}} by the human name of the resource class,
	269	+which is "Project" in this case.
	270	+
	271	+But sometimes, flash messages are not that simple. Sometimes you want to say
	272	+the title of the project while updating a project. Well, that's easy also:
	273	+
	274	+ flash:
	275	+ projects:
	276	+ update:
	277	+ notice: "Hooray! The project "{{project_title}}" was updated!"
	278	+
	279	+Since :project_title is not available for interpolation by default, you have
	280	+to overwrite interpolation_options.
	281	+
	282	+ def interpolation_options
	283	+ { :project_title => @project.title }
	284	+ end
	285	+
	286	+Then you will finally have:
	287	+
	288	+ "Hooray! The project "Plataforma" was updated!"
	289	+
	290	+By default, resource name is capitalized. If you want to make it lower case, you
	291	+can add to your application controller:
	292	+
	293	+ def interpolation_options
	294	+ { :resource_name => resource_class.human_name.downcase }
	295	+ end
	296	+
	297	+Finally, if your controller is namespaced, for example Admin::ProjectsController,
	298	+the messages will be checked in the following order:
	299	+
	300	+ flash.admin.projects.create.notice
	301	+ flash.admin.actions.create.notice
	302	+ flash.projects.create.notice
	303	+ flash.actions.create.notice
	304	+
	305	+Has Scope
	306	+---------
	307	+
	308	+InheritedResources tries to integrate nicely with your model. In order to do so,
	309	+it also is named_scope fluent. Let's suppose our Project model with the scopes:
	310	+
	311	+ class ProjectsController < ActiveRecord::Base
	312	+ named_scope :featured, :conditions => { :featured => true }
	313	+ named_scope :by_methodology, proc {\|methodology\| { :conditions => { :methodology => methodology } } }
	314	+ named_scope :limit, proc{\|limit\| :limit => limit.to_i }
	315	+ end
	316	+
	317	+Your controller:
	318	+
	319	+ class ProjectsController < InheritedResources::Base
	320	+ has_scope :featured, :boolean => true, :only => :index
	321	+ has_scope :by_methodology
	322	+ has_scope :limit, :default => 10
	323	+ end
	324	+
	325	+Then for each request:
	326	+
	327	+ /projects
	328	+ #=> acts like a normal request, but returning 10 projects
	329	+
	330	+ /projects?featured=true
	331	+ #=> calls the featured named scope and bring 10 featured projects
	332	+
	333	+ /projects?featured=true&by_methodology=agile&limit=20
	334	+ #=> brings 20 featured projects with methodology agile
	335	+
	336	+You can retrieve the current scopes in use with :current_scopes method.
	337	+In the last case, it would return:
	338	+
	339	+ { :featured => "true", :by_methodology => "agile", :limit => "20" }
	340	+
	341	+Finally, let's suppose you store on the session how many projects the user sees
	342	+per page. In such cases, you can give a proc as default value:
	343	+
	344	+ has_scope :limit, :default => proc{\|c\| c.session[:limit] \|\| 10 }
	345	+
	346	+Belongs to
	347	+----------
	348	+
	349	+Finally, our Projects are going to get some Tasks. Then you create a
	350	+TasksController and do:
	351	+
	352	+ class TasksController < InheritedResources::Base
	353	+ belongs_to :project
	354	+ end
	355	+
	356	+belongs_to accepts several options to be able to configure the association.
	357	+For example, if you want urls like /projects/:project_title/tasks, you can
	358	+customize how InheritedResources find your projects:
	359	+
	360	+ class TasksController < InheritedResources::Base
	361	+ belongs_to :project, :finder => :find_by_title!, :param => :project_title
	362	+ end
	363	+
	364	+It also accepts :route_name, :parent_class and :instance_name as options.
	365	+Check the lib/inherited_resources/class_methods.rb for more.
	366	+
	367	+Nested belongs to
	368	+-----------------
	369	+
	370	+Now, our Tasks get some Comments and you need to nest even deeper. Good
	371	+practices says that you should never nest more than two resources, but sometimes
	372	+you have to for security reasons. So this is an example of how you can do it:
	373	+
	374	+ class CommentsController < InheritedResources::Base
	375	+ nested_belongs_to :project, :task
	376	+ end
	377	+
	378	+If you need to configure any of these belongs to, you can nested them using blocks:
	379	+
	380	+ class CommentsController < InheritedResources::Base
	381	+ belongs_to :project, :finder => :find_by_title!, :param => :project_title do
	382	+ belongs_to :task
	383	+ end
	384	+ end
	385	+
	386	+Warning: calling several belongs_to is the same as nesting them:
	387	+
	388	+ class CommentsConroller < InheritedResources::Base
	389	+ belongs_to :project
	390	+ belongs_to :task
	391	+ end
	392	+
	393	+In other words, the code above is the same as calling nested_belongs_to.
	394	+
	395	+Polymorphic belongs to
	396	+----------------------
	397	+
	398	+We can go even further. Let's suppose our Projects can now have Files, Messages
	399	+and Tasks, and they are all commentable. In this case, the best solution is to
	400	+use polymorphism:
	401	+
	402	+ class CommentsController < InheritedResources::Base
	403	+ belongs_to :task, :file, :message, :polymorphic => true
	404	+ # polymorphic_belongs_to :task, :file, :message
	405	+ end
	406	+
	407	+You can even use it with nested resources:
	408	+
	409	+ class CommentsController < InheritedResources::Base
	410	+ belongs_to :project do
	411	+ belongs_to :task, :file, :message, :polymorphic => true
	412	+ end
	413	+ end
	414	+
	415	+The url in such cases can be:
	416	+
	417	+ /project/1/task/13/comments
	418	+ /project/1/file/11/comments
	419	+ /project/1/message/9/comments
	420	+
	421	+When using polymorphic associations, you get some free helpers:
	422	+
	423	+ parent? #=> true
	424	+ parent_type #=> :task
	425	+ parent_class #=> Task
	426	+ parent #=> @task
	427	+
	428	+Optional belongs to
	429	+-------------------
	430	+
	431	+Later you decide to create a view to show all comments, independent if they belong
	432	+to a task, file or message. You can reuse your polymorphic controller just doing:
	433	+
	434	+ class ProjectsController < InheritedResources::Base
	435	+ belongs_to :task, :file, :message, :optional => true
	436	+ # optional_belongs_to :task, :file, :message
	437	+ end
	438	+
	439	+This will handle all those urls properly:
	440	+
	441	+ /comment/1
	442	+ /tasks/2/comment/5
	443	+ /files/10/comment/3
	444	+ /messages/13/comment/11
	445	+
	446	+This is treated as a special type of polymorphic associations, thus all helpers
	447	+are available. As you expect, when no parent is found, the helpers return:
	448	+
	449	+ parent? #=> false
	450	+ parent_type #=> nil
	451	+ parent_class #=> nil
	452	+ parent #=> nil
	453	+
	454	+Singletons
	455	+----------
	456	+
	457	+Now we are going to add manager to projects. We say that Manager is a singleton
	458	+resource because a Project has just one manager. You should declare it as
	459	+has_one (or resource) in your routes.
	460	+
	461	+To declare an association as singleton, you just have to give the :singleton
	462	+option.
	463	+
	464	+ class ManagersController < InheritedResources::Base
	465	+ belongs_to :project, :singleton => true
	466	+ # singleton_belongs_to :project
	467	+ end
	468	+
	469	+It will deal with everything again and hide the action :index from you.
	470	+
	471	+URL Helpers
	472	+-----------
	473	+
	474	+When you use InheritedResources it creates some URL helpers.
	475	+And they handle everything for you. :)
	476	+
	477	+ # /posts/1/comments
	478	+ resource_url # => /posts/1/comments/#{@comment.to_param}
	479	+ resource_url(comment) # => /posts/1/comments/#{comment.to_param}
	480	+ new_resource_url # => /posts/1/comments/new
	481	+ edit_resource_url # => /posts/1/comments/#{@comment.to_param}/edit
	482	+ edit_resource_url(comment) #=> /posts/1/comments/#{comment.to_param}/edit
	483	+ collection_url # => /posts/1/comments
	484	+
	485	+ # /projects/1/tasks
	486	+ resource_url # => /projects/1/tasks/#{@task.to_param}
	487	+ resource_url(task) # => /projects/1/tasks/#{task.to_param}
	488	+ new_resource_url # => /projects/1/tasks/new
	489	+ edit_resource_url # => /projects/1/tasks/#{@task.to_param}/edit
	490	+ edit_resource_url(task) # => /projects/1/tasks/#{task.to_param}/edit
	491	+ collection_url # => /projects/1/tasks
	492	+
	493	+ # /users
	494	+ resource_url # => /users/#{@user.to_param}
	495	+ resource_url(user) # => /users/#{user.to_param}
	496	+ new_resource_url # => /users/new
	497	+ edit_resource_url # => /users/#{@user.to_param}/edit
	498	+ edit_resource_url(user) # => /users/#{user.to_param}/edit
	499	+ collection_url # => /users
	500	+
	501	+Those urls helpers also accepts a hash as options, just as in named routes.
	502	+
	503	+ # /projects/1/tasks
	504	+ collection_url(:page => 1, :limit => 10) #=> /projects/1/tasks?page=1&limit=10
	505	+
	506	+Another nice thing is that those urls are not guessed during runtime. They are
	507	+all created when your application is loaded (except for polymorphic
	508	+associations, that relies on Rails polymorphic_url).
	509	+

	11	+ #
	12	+ # belongs_to accepts several options to be able to configure the association.
	13	+ # For example, if you want urls like /projects/:project_title/tasks, you
	14	+ # can customize how InheritedResources find your projects:
	15	+ #
	16	+ # class TasksController < InheritedResources::Base
	17	+ # belongs_to :project, :finder => :find_by_title!, :param => :project_title
	18	+ # end
	19	+ #
	20	+ # It also accepts :route_name, :parent_class and :instance_name as options.
	21	+ # Check the lib/inherited_resources/class_methods.rb for more.
	22	+ #
	23	+ # = nested_belongs_to
	24	+ #
	25	+ # Now, our Tasks get some Comments and you need to nest even deeper. Good
	26	+ # practices says that you should never nest more than two resources, but sometimes
	27	+ # you have to for security reasons. So this is an example of how you can do it:
	28	+ #
	29	+ # class CommentsController < InheritedResources::Base
	30	+ # nested_belongs_to :project, :task
	31	+ # end
	32	+ #
	33	+ # If you need to configure any of these belongs to, you can nested them using blocks:
	34	+ #
	35	+ # class CommentsController < InheritedResources::Base
	36	+ # belongs_to :project, :finder => :find_by_title!, :param => :project_title do
	37	+ # belongs_to :task
	38	+ # end
	39	+ # end
	40	+ #
	41	+ # Warning: calling several belongs_to is the same as nesting them:
	42	+ #
	43	+ # class CommentsController < InheritedResources::Base
	44	+ # belongs_to :project
	45	+ # belongs_to :task
	46	+ # end
	47	+ #
	48	+ # In other words, the code above is the same as calling nested_belongs_to.
