ActsAsStatusChangable

This gem provides the facility to automatically track history of changes in +activerecord+ models built around the concept of state machine.

Model

Firstly, enable tracking in the model(s):

  class Gizmo < ActiveRecord::Base
    acts_as_status_changeable :status, :other_status
  end

  class Thingamabob < ActiveRecord::Base
    acts_as_status_changeable :status
  end

Changes of these attributes will be persisted in status_changes table.

Examples

  Gizmo.with_past_status(:other_status, "broken").count

  gizmo = Gizmo.create!(:status => :new)
  gizmo.status_changes.last.inspect # => #<ActsAsStatusChangeable::StatusChange id: 1, status_changeable_id: 1,
                                    # status_changeable_type: "Gizmo", status_name: "status", status: "new",
                                    # created_at: "2012-11-01 17:58:15", updated_at: "2012-11-01 17:58:15">

  gizmo.was_in_status?(:status, :new) # => true
  gizmo.status_date(:status, :new) # => time of most recent transition to given status
