acts_as_audited is an ActiveRecord extension that logs all changes to your models in an audits table, with optional revision comments.
Rails::Initializer.run do |config| ... config.gem 'acts_as_audited' ... end
At your application root, run:
$ rake gems:install
Generate the migration:
If installing without a previous version of acts_as_audited or you do not mind overwriting your audits table:
$ script/generate audited_migration add_audits_table
If upgrading from a version of acts_as_audited that does not contain comment functionality:
$ script/generate audited_migration_update update_audits_table
After running one of the generators:
$ rake db:migrate
Declare acts_as_audited on your models:
class User < ActiveRecord::Base acts_as_audited :except => [:password, :mistress] end
Within a web request, will automatically record the user that made the change if your controller has a current_user method. Comments can be added to an audit by setting model.audit_comments before create/update/destroy. If the :comment_required option is given to acts_as_audited, the save/update/destroy action will fail with add an error on model.audit_comment and triggering a transaction rollback if model.audit_comment is nil.
To record a user in the audits outside of a web request, you can use as_user:
Audit.as_user(user) do # Perform changes on audited models end
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
acts_as_audited works with Rails 2.1 or later.
