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
  

Usage

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 current_user method.

class ApplicationController < ActionController::Base
  audit User, List, Item => {:except => :password}
protected
  def current_user
    @user ||= User.find(session[:user])
  end
end

To get auditing outside of Rails you can explicitly declare acts_as_audited on your models:

class User < ActiveRecord::Base
  acts_as_audited :except => [:password, :mistress]
end

To record a user in the audits when the sweepers are not available, you can use as_user:

Audit.as_user( user ) do
  # Perform changes on audited models
end

See 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 2.1 or later.
