acts_as_revisioned v0.1a

acts_as_revisioned is a change auditing system for ruby_on_rail applications. It uses a NoSQL Key-Value store to create records of changes. It generates copies of records after changes in NoSQL with matching :id keys, but has additional keys to support versioning.

Example

item.rb

class Item << ActiveRecord:Base
  acts_as_revisioned :except => [:created_at,:updated_at]
end

irb:

item = Item.create!({:name => "Test Item"})
item.id # 1
item.revisions # [{:version => 1, :name => "Test Item"}]
item.name = "an_extremely_unlikely_name"
item.save
item.revisions # [{:version => 2, :name => "an_extremely_unlikely_name"}, {:version => 1, :name => "Test Item"}]

Requirements

ruby >= 1.9.2
rails >= 3.x
MongoDB

Installation

1) Put it in your Gemfile and run ‘bundle install`

OR `gem install acts_as_revisioned`

2) rails generate acts_as_revisioned:install

Usage

In your ActiveRecord model, set acts_as_revisioned:

class Item < ActiveRecord:Base
  acts_as_revisioned :except => [:created_at, :udpated_at]
end

IMPORTANT NOTES

This is not a guarantee for logging changes and revision control. Actual revision control can be created, but it’s up to you to create the logic. Since it is located in a separate NoSQL database, there is no guarantee for data consistency. This is just useful gem to search because other revision gems can’t search the actual changes.
