Audit activerecord models like a boss. Tested in rails 4 and ruby 2.0.0.
This project is heavily based in audited gem.
In your gemfile
gem "espinita"
In console
$ rake espinita:install:migrations
$ rake db:migrate
class Post < ActiveRecord::Base
auditable
end
@post.create(title: "an awesome blog post" )
Espinita will create an audit by default on creation , edition and destroy:
@post.audits.size #=> 1
Espinita provides options to include or exclude columns to trigger the creation of audit.
class Post < ActiveRecord::Base
auditable only: [:title] # except: [:some_column]
end
And lets you declare the callbacks you want for audit creation:
class Post < ActiveRecord::Base
auditable on: [:create] # on: [:create, :update]
end
You can find the audits records easily:
@post.audits.first #=> #<Espinita::Audit id: 1, auditable_id: 1, auditable_type: "Post", user_id: 1, user_type: "User", audited_changes: {"title"=>[nil, "MyString"], "created_at"=>[nil, 2013-10-30 15:50:14 UTC], "updated_at"=>[nil, 2013-10-30 15:50:14 UTC], "id"=>[nil, 1]}
Espinita will save the model changes in a serialized column called audited_changes:
@post.audits.first.audited_changes #=> {"title"=>[nil, "MyString"], "created_at"=>[nil, 2013-10-30 15:50:14 UTC], "updated_at"=>[nil, 2013-10-30 15:50:14 UTC], "id"=>[nil, 1]}
Espinita will detect the current user when records saved from rails controllers. By default Espinita uses current_user method but you can change it:
Espinita.current_user_method = :authenticated_user
