Change status if the task is assigned to a participant from the testing group?

Question

Ruby on Rails

Good afternoon!
There is a project, in which the task is transferred to users, each user has his own role - development, testing, etc.
Those. after the task is completed by the developer, he assigns the task to the tester, let's say V.V. Volodin.
How can I set up automatic status changes, depending on who is assigned as responsible?
Thank you!

Answer 1

I would insert a callback into the model:

before_update :change_status
def change_status
self.status = :testing if self.user.type.tester?
end
