How to save a model without sending a signal?

Question

How can I save a model, such that signals arent sent. (post_save and pre_save)

Answer 1

If you have mutual relations on models and their signals still you can decouple signal's logic to have more signals of same type, and handle your logic in more sophisticated way:

You can check in signals, the state of object:

kwargs['created']

You can check the state of any pasted extra value: So in one signal, you will read at first:

if `kwargs['instance'].skip_signals`:
   return

and in another place, before save() you will just set that skip_signals on the specific object, in specific situation. (there is no need to define it as model field)

You can also do not emit signals:

• by overriding method(s) on models,
• or by adding own save_without_signals(),
• or just as mentioned already, doing filter(pk=<>).update(...)
