Please use a state machine like github.com/pluginaweek/state_machine which supports Mongoid. It's been great working on workflow_on_mongoid over the years, but I no longer have the time to support the gem. Since there is no plugin mechanism in the original workflow gem, keeping workflow_on_mongoid up-to-date and tested has become increasingly difficult. At the same time, I've had less and less free time to devote to open source projects. Thanks for your support!
In your Gemfile, instead of
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.
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.y) tracks changes to workflow_on_mongoid itself.
class MongoidImage include Mongoid::Document field :title field :status include Workflow # Note this *must* occur after at least one # Mongoid::* include, otherwise your status will not be persisted. 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. Do ensure your include Workflow line occurs after at least one Mongoid::Include line.
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.
workflow_on_mongoid is hosted on Github: github.com/bowsersenior/workflow_on_mongoid . It's a tiny project, but your contributions, forkings, comments and feedback are definitely appreciated.
