How to pass kwargs from save to post_save signal

Question

I\'m wiring up a custom post_save signal and noticed that I can\'t seem to find an easy way to pass a set of kwargs.

During the save itself (inside a custom form)

Answer 1

We can pass additional arguments as below:

def save(self, commit=True):
    user = super(CustomFormThing, self).save(commit=False)
    #set some other attrs on user here ...
    if commit:
        user.save(signal_kwargs={'_some': 'some', '_other': 'other'})

    return user

And you can get it from the post save method like:

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    some_id = kwargs.get('some', None)
    other_id = kwargs.get('other', None)
    if created:
        #do something with the kwargs above...
