improve how ActiveRecord::Observer defines callbacks on observed models
Instead of using a single notify_observers call for
every callback type,
each observer now registers a unique callback for itself.
Example:
before_save :_notify_user_observer_for_before_save
def _notify_user_observer_for_before_save
observer.update(:before_save, self)
end
Benefit: "before" callbacks halt when
observer.update returns false.
This way, ActiveRecord observers can prevent records from
saving.
