= acts_as_audited
acts_as_audited is an ActiveRecord extension that logs all changes to your models in an audits table.
The purpose of this fork is to store both the previous values and the changed value, making each audit record selfcontained.
== Installation
* Install the plugin into your rails app
If you are using Rails 2.1:
script/plugin install git://github.com/collectiveidea/acts_as_audited.git
For versions prior to 2.1:
git clone git://github.com/collectiveidea/acts_as_audited.git vendor/plugins/acts_as_audited
* Generate the migration
script/generate audited_migration add_audits_table
rake db:migrate
== Auditing in Rails
If you're using acts_as_audited within Rails, you can simply declare which models should be audited. acts_as_audited can also automatically record the user that made the change if your controller has a <tt>current_user</tt> method.
class ApplicationController < ActionController::Base
audit User, List, Item
protected
def current_user
@user ||= User.find(session[:user])
end
end
== Customizing
To get auditing outside of Rails, or to customize which fields are audited within Rails, you can explicitly declare <tt>acts_as_audited</tt> on your models:
class User < ActiveRecord::Base
acts_as_audited :except => [:password, :mistress]
end
See http://opensoul.org/2006/07/21/acts_as_audited for more information.
== Caveats
If your model declares +attr_accessible+ after +acts_as_audited+, you need to set +:protect+ to false. acts_as_audited uses +attr_protected+ internally to prevent malicious users from unassociating your audits, and Rails does not allow both +attr_protected+ and +attr_accessible+. It will default to false if +attr_accessible+ is called before +acts_as_audited+, but needs to be explicitly set if it is called after.
class User < ActiveRecord::Base
acts_as_audited :protect => false
attr_accessible :name
end
=== ActiveScaffold
Many users have also reported problems with acts_as_audited and ActiveScaffold, which appears to be caused by a limitation in ActiveScaffold not supporting polymorphic associations. To get it to work with ActiveScaffold:
class ApplicationController < ActionController::Base
audit MyModel, :only => [:create, :update, :destroy]
end
== Compatability
acts_as_audited works with Rails 2.0 or later.
