= acts_as_versioned
This library adds simple versioning to an ActiveRecord module. ActiveRecord is required.
== Resources
Install
* gem install acts_as_versioned
Rubyforge project
* http://rubyforge.org/projects/ar-versioned
RDocs
* http://ar-versioned.rubyforge.org
Subversion
* http://techno-weenie.net/svn/projects/acts_as_versioned
Collaboa
* http://collaboa.techno-weenie.net/repository/browse/acts_as_versioned
Special thanks to Dreamer on ##rubyonrails for help in early testing. His ServerSideWiki (http://serversidewiki.com)
was the first project to use acts_as_versioned <em>in the wild</em>.

vendor/plugins/acts_as_versioned/RUNNING_UNIT_TESTS vendored
View File

@ -1,41 +0,0 @@
== Creating the test database
The default name for the test databases is "activerecord_versioned". If you
want to use another database name then be sure to update the connection
adapter setups you want to test with in test/connections/<your database>/connection.rb.
When you have the database online, you can import the fixture tables with
the test/fixtures/db_definitions/*.sql files.
Make sure that you create database objects with the same user that you specified in i
connection.rb otherwise (on Postgres, at least) tests for default values will fail.
== Running with Rake
The easiest way to run the unit tests is through Rake. The default task runs
the entire test suite for all the adapters. You can also run the suite on just
one adapter by using the tasks test_mysql_ruby, test_ruby_mysql, test_sqlite,
or test_postresql. For more information, checkout the full array of rake tasks with "rake -T"
Rake can be found at http://rake.rubyforge.org
== Running by hand
Unit tests are located in test directory. If you only want to run a single test suite,
or don't want to bother with Rake, you can do so with something like:
cd test; ruby -I "connections/native_mysql" base_test.rb
That'll run the base suite using the MySQL-Ruby adapter. Change the adapter
and test suite name as needed.
== Faster tests
If you are using a database that supports transactions, you can set the
"AR_TX_FIXTURES" environment variable to "yes" to use transactional fixtures.
This gives a very large speed boost. With rake:
rake AR_TX_FIXTURES=yes
Or, by hand:
AR_TX_FIXTURES=yes ruby -I connections/native_sqlite3 base_test.rb

# Specify this act if you want to save a copy of the row in a versioned table. This assumes there is a
# versioned table ready and that your model has a version field. This works with optimistic locking if the lock_version
# column is present as well.
#
# The class for the versioned model is derived the first time it is seen. Therefore, if you change your database schema you have to restart
# your container for the changes to be reflected. In development mode this usually means restarting WEBrick.
#
# class Page < ActiveRecord::Base
# # assumes pages_versions table
# acts_as_versioned

#
# Example:
#
# page = Page.create(:title => 'hello world!')
# page.version # => 1
#
# page.title = 'hello world'
# page.save
# page.version # => 2
# page.versions.size # => 2
#
# page.revert_to(1) # using version number
# page.title # => 'hello world!'
#
# page.revert_to(page.versions.last) # using versioned instance
# page.title # => 'hello world'
#
# page.versions.earliest # efficient query to find the first version
# page.versions.latest # efficient query to find the most recently created version
#
#
# Simple Queries to page between versions
#
# page.versions.before(version)
# page.versions.after(version)
#
# Access the previous/next versions from the versioned model itself

def self.included(base) # :nodoc:

end
module ClassMethods
# == Configuration options
#
# * <tt>class_name</tt> - versioned model class name (default: PageVersion in the above example)
# * <tt>table_name</tt> - versioned model table name (default: page_versions in the above example)
# * <tt>foreign_key</tt> - foreign key used to relate the versioned model to the original model (default: page_id in the above example)
# * <tt>inheritance_column</tt> - name of the column to save the model's inheritance_column value for STI. (default: versioned_type)
# * <tt>version_column</tt> - name of the column in the model that keeps the version number (default: version)
# * <tt>sequence_name</tt> - name of the custom sequence to be used by the versioned model.
# * <tt>limit</tt> - number of revisions to keep, defaults to unlimited
# * <tt>if</tt> - symbol of method to check before saving a new version. If this method returns false, a new version is not saved.
# For finer control, pass either a Proc or modify Model#version_condition_met?
#
# acts_as_versioned :if => Proc.new { |auction| !auction.expired? }
#
# or...
#
# class Auction
# def version_condition_met? # totally bypasses the <tt>:if</tt> option
# !expired?
# end
# end
#
# * <tt>if_changed</tt> - Simple way of specifying attributes that are required to be changed before saving a model. This takes
# either a symbol or array of symbols. WARNING - This will attempt to overwrite any attribute setters you may have.
# Use this instead if you want to write your own attribute setters (and ignore if_changed):
#
# def name=(new_name)
# write_changed_attribute :name, new_name
# end
#
# * <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
# to create an anonymous mixin:
#
# class Auction
# acts_as_versioned do
# def started?
# !started_at.nil?
# end
# end
# end
#
# or...
#
# module AuctionExtension
# def started?
# !started_at.nil?
# end
# end
# class Auction
# acts_as_versioned :extend => AuctionExtension
# end
#
# Example code:
#
# @auction = Auction.find(1)
# @auction.started?
# @auction.versions.first.started?
#
# == Database Schema
#
# The model that you're versioning needs to have a 'version' attribute. The model is versioned
# into a table called #{model}_versions where the model name is singlular. The _versions table should
# contain all the fields you want versioned, the same version column, and a #{model}_id foreign key field.
#
# A lock_version field is also accepted if your model uses Optimistic Locking. If your table uses Single Table inheritance,
# then that field is reflected in the versioned model as 'versioned_type' by default.
#
# Acts_as_versioned comes prepared with the ActiveRecord::Acts::Versioned::ActMethods::ClassMethods#create_versioned_table
# method, perfect for a migration. It will also create the version column if the main model does not already have it.
#
# class AddVersions < ActiveRecord::Migration
# def self.up
# # create_versioned_table takes the same options hash
# # that create_table does
# Post.create_versioned_table
# end
#
# def self.down
# Post.drop_versioned_table
# end
# end
#
# == Changing What Fields Are Versioned
#
