As Jason implies: both tasks of the observer, not the dispatcher. If a dispatcher does not call all registered observers as part of the API contract, you have no way to debug it (given that a signal dispatcher should be a black box to you) or at best you'd have 2 places where things can go wrong instead of just one. You thought up some use cases, but given the tone of your mail you mybe spent some time trying to shoehorn some code into a signal/observer pattern? Perhaps it's not the right fit for your problem. -- Melvyn Sopacua [1] https://docs.djangoproject.com/en/2.0/topics/signals/#preventing-duplicate-signals -- You received this message because you are subscribed to the Google Groups "Django users" group.

deciding whether to act or not is really part of the signal handler, to be honest. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Is there any way to disable dispatching of signals?
Is there any way to disable dispatching of signals? If not, I truly truly think there should be a way to do it :) Possible use cases: - Prevent signals being called recursively because the signal code dispatched the same signal. - Disable for scripts or management commands - Just bypass the signals on specific actions. -- You received this message because you are subscribed to the Google Groups "Django users" group.
