Rails AASM; How to do some action if the specific transition is occured

I use state machine gem called AASM on rails.

There are an event which has two types of transitions.

Three three types of state

state pending
state past_due
state paid

pending can be changed into paid past_due can be changed into paid 

  event :pay do
      transitions from: [:pending, :past_due], to: :paid
  end

So here I'd love to do some action only if past_due goes paid.

Any idea?

Solution

  • One way to do this is to define transitions in two separate statements:

    event :pay do
  transitions from: :pending, to: :paid
  transitions from: :past_due, to: :paid, after: :do_your_custom_action
end

    See more about callbacks in the docs.
