  1 +== Creating the test database
  2 +
  3 +The default name for the test databases is "activerecord_versioned". If you
  4 +want to use another database name then be sure to update the connection
  5 +adapter setups you want to test with in test/connections/<your database>/connection.rb.
  6 +When you have the database online, you can import the fixture tables with
  7 +the test/fixtures/db_definitions/*.sql files.
  8 +
  9 +Make sure that you create database objects with the same user that you specified in i
  10 +connection.rb otherwise (on Postgres, at least) tests for default values will fail.
  11 +
  12 +== Running with Rake
  13 +
  14 +The easiest way to run the unit tests is through Rake. The default task runs
  15 +the entire test suite for all the adapters. You can also run the suite on just
  16 +one adapter by using the tasks test_mysql_ruby, test_ruby_mysql, test_sqlite,
  17 +or test_postresql. For more information, checkout the full array of rake tasks with "rake -T"
  18 +
  19 +Rake can be found at http://rake.rubyforge.org
  20 +
  21 +== Running by hand
  22 +
  23 +Unit tests are located in test directory. If you only want to run a single test suite,
  24 +or don't want to bother with Rake, you can do so with something like:
  25 +
  26 + cd test; ruby -I "connections/native_mysql" base_test.rb
  27 +
  28 +That'll run the base suite using the MySQL-Ruby adapter. Change the adapter
  29 +and test suite name as needed.
  30 +
  31 +== Faster tests
  32 +
  33 +If you are using a database that supports transactions, you can set the
  34 +"AR_TX_FIXTURES" environment variable to "yes" to use transactional fixtures.
  35 +This gives a very large speed boost. With rake:
  36 +
  37 + rake AR_TX_FIXTURES=yes
  38 +
  39 +Or, by hand:
  40 +
  41 + AR_TX_FIXTURES=yes ruby -I connections/native_sqlite3 base_test.rb

  75 + # == Configuration options
  76 + #
  77 + # * <tt>class_name</tt> - versioned model class name (default: PageVersion in the above example)
  78 + # * <tt>table_name</tt> - versioned model table name (default: page_versions in the above example)
  79 + # * <tt>foreign_key</tt> - foreign key used to relate the versioned model to the original model (default: page_id in the above example)
  80 + # * <tt>inheritance_column</tt> - name of the column to save the model's inheritance_column value for STI. (default: versioned_type)
  81 + # * <tt>version_column</tt> - name of the column in the model that keeps the version number (default: version)
  82 + # * <tt>sequence_name</tt> - name of the custom sequence to be used by the versioned model.
  83 + # * <tt>limit</tt> - number of revisions to keep, defaults to unlimited
  84 + # * <tt>if</tt> - symbol of method to check before saving a new version. If this method returns false, a new version is not saved.
  85 + # For finer control, pass either a Proc or modify Model#version_condition_met?
  86 + #
  87 + # acts_as_versioned :if => Proc.new { |auction| !auction.expired? }

  98 + # either a symbol or array of symbols.
  99 + #
  100 + # * <tt>extend</tt> - Lets you specify a module to be mixed in both the original and versioned models. You can also just pass a block

  104 + # acts_as_versioned do

  129 + #
  130 + # The model that you're versioning needs to have a 'version' attribute. The model is versioned
  131 + # into a table called #{model}_versions where the model name is singlular. The _versions table should
  132 + # contain all the fields you want versioned, the same version column, and a #{model}_id foreign key field.
  133 + #
  134 + # A lock_version field is also accepted if your model uses Optimistic Locking. If your table uses Single Table inheritance,
  135 + # then that field is reflected in the versioned model as 'versioned_type' by default.
  136 + #
  137 + # Acts_as_versioned comes prepared with the ActiveRecord::Acts::Versioned::ActMethods::ClassMethods#create_versioned_table
  138 + # method, perfect for a migration. It will also create the version column if the main model does not already have it.
  139 + #
  140 + # class AddVersions < ActiveRecord::Migration
