About workflow_on_mongoid¶ ↑

workflow_on_mongoid lets you use the Workflow gem with your Mongoid documents to add state machine functionality.

How to use it¶ ↑

In your Gemfile, instead of

gem 'workflow'

do

gem 'workflow_on_mongoid'

That is all. Now you can use Workflow with your Mongoid documents. Of course, you can still continue to use Workflow with ActiveRecord, Remodel and plain objects. All that workflow_on_mongoid does is to add Mongoid support. You can use all the features of Workflow with Mongoid models, including reflection of events & states, transition hooks, support for inherited models, etc. Just refer to the Workflow docs.

Versioning¶ ↑

The version numbers of workflow_on_mongoid track the latest supported version of Workflow . The major version number (x.x.x) matches the latest supported version of the Workflow gem, while the minor version number (0.7.0.x) tracks changes to workflow_on_mongoid itself.

The current version is 0.8.0 .

Example¶ ↑

class MongoidImage
  include Mongoid::Document

  field :title
  field :status

  include Workflow

  workflow_column :status

  workflow do
    state :unconverted do
      event :convert, :transitions_to => :converted
    end
    state :converted
  end
end

See the tests for Mongoid for more examples.

Tests¶ ↑

I’ve included all the tests from the original workflow gem and added comprehensive tests for Mongoid support, which is now as well-tested as ActiveRecord support. Including the existing tests ensures that workflow_on_mongoid implements support for Mongoid documents without breaking anything.
