Question

How do I go about calling a method on state change in AASM?

I’d like to call update_foo when the state transitions to paid in the following model:

class Foo < ActiveRecord::Base   include AASM    # State Machine   aasm_initial_state :incomplete   aasm_state :incomplete   aasm_state :paid    aasm_event :pay do     transitions :from => :incomplete, :to => :paid   end    def update_foo   ...   end end 

Answer 1

Nevermind – figured it out:

aasm_state :paid, :enter => :update_foo
