Passing variables to Rails StateMachine gem transitions

Question

Is it possible to send variables in the the transition? i.e.

@car.crash!(:crashed_by => current_user)

I have callbacks in my model but I nee

Answer 1

I don't think you can pass params to events with that gem, so maybe you could try storing the current_user on @car (temporarily) so that your audit callback can access it.

In controller

@car.driver = current_user

In callback

after_crash do |car, transition|
   create_audit_log car.driver, transition
end

Or something along those lines.. :)
