Getting list of states/events from a model that AASM

Question

I successfully integrated the most recent AASM gem into an application, using it for the creation of a wizard. In my case I have a model order

class Order < ActiveRecord::Base

  belongs_to :user
  has_one :billing_plan, :dependent => :destroy
  named_scope :with_user, ..... <snip>

  include AASM

  aasm_column :aasm_state
  aasm_initial_state :unauthenticated_user

  aasm_state :unauthenticated_user, :after_exit => [:set_state_completed]
  aasm_state : <snip>

  <and following the event definitions>

end

Now I would like to give an administrator the possibility to create his own graphs through the AASM states. Therefore I created two additional models called OrderFlow and Transition where there order_flow has many transitions and order belongs_to order_flow.

No problem so far. Now I would like to give my admin the possibility to dynamically add existing transitions / events to an order_flow graph.

The problem now is, that I do not find any possibility to get a list of all events / transitions out of my order model. aasm_states_for_select seems to be the correct candidate, but I cannot call it on my order model.

Can anyone help?

Thx in advance. J.

With version 3.0.18, you can should use ClassName.aasm.states
