Pass a parameter to aasm event

I am using aasm statemachine. I have the below event. What this does is changes the state from order_created to payment_response_received. So after changing this I want to call a method verify_payment_response(data). I can make this state change by calling @booking.move_to_payment_response_received! , but how can I pass parameters for use in the after callback?

event :move_to_payment_response_received do
  after_commit do
         self.verify_payment_response(data) #How can I pass this data param from my controller
  end
  transitions from: :order_created, to: :payment_response_received
end

You can assign the data to a local variable before firing the event:

# in your model

attr_accessor :payment_response_data

event :move_to_payment_response_received, :after_commit => :verify_payment_response do
  transitions from: :order_created, to: :payment_response_received
end

private

def verify_payment_response
  data = payment_response_data

  # already existing code to verify `data`
end

And use this in your controller like this:

@booking.payment_response_data = data
@booking.move_to_payment_response_received!
