[Question] Is there an easy way to rollback a transition?

[leandrofinger]

Hi guys!

After transitioning and depending on the record I should run an integration call and depending on this response I need rollback the last transition. Is there an easy way to do that, or should I allow the transition backward and transition it again?

At least what I know:

• Destroy the last transition via state_machine.last_transition.destroy; please make sure you have after_destroy :update_most_recent, if: :most_recent? code, which updates the previous most recent transition's row value most_recent to true.
• Add a backwards transition to the state machine, which is preferred if you would like to make the logic on rollback.
