Question

I have an attribute for my users called :last_request_at, :null => false

I need to set this attribute to the current time on sign up / create. But I don’t know how?

a hidden field in the sign up form maybe? If yes how would that look like? Or how does Devise set his trackable attributes on signup/create to the current time?

EDIT

I put this in the user model:

before_save :set_last_request

def set_last_request
  self.update_attribute(:last_request_at, Time.now)
end

but then I get:

stack level too deep

Answer 1

I would set the attribute in your controller action. Your stack level too deep error is because update_attribute calls save at the end. You are infinitely calling set_last_request.

I would just call @record.last_request_at = Time.now in your controller action, or modify your before_save hook to just do self.last_request_at = Time.now.
