How to pass kwargs from save to post_save signal

Built-in signals are sent by Django, so you can’t control their kwargs.

You can:

1. Define and send your own signals.

2. Store additional info in model instance. Like this

   def save(self, commit=True):
       user = super(CustomFormThing, self).save(commit=False)
       #set some other attrs on user here ...
       user._some="some"
       user._other="other"
       if commit:
           user.save()
   
       return user
   
   @receiver(post_save, sender=User)
   def create_profile(sender, instance, created, **kwargs):
       some_id = getattr(instance, '_some', None)
       other_id = getattr(instance, '_other', None)
   
       if created:
           #do something with the kwargs above...
