django signals: receiver and proxy model?

Question

I set a receiver on a post_save signal and I was hoping catching the signals for all the proxy of my Model by setting the sender to the main Model but it does not seem to work:

class MyObject(models.Model):
    ....

class MyObjectProxy(MyObject):

    class Meta:
        proxy = True

# The receiver
# How to avoid writing another one for sender=MyObjectProxy ?
@receiver(post_save, sender=MyObject)
...

My receiver is not triggered when that happens:

obj = MyObjectProxy()
obj.save()

Is that normal? I have to set a receiver for each proxy? Can I set sender to a list of models?

Thanks.

Umm. Signals fire when you save an instance of the model. Why are you calling save() on the model class? — Bibhas Debnath, Mar 18 '14 at 05:03
@Michael Did you solve this issue at that time? I got the same issue here. — Perfect, Jul 26 '20 at 03:02

As of now, I think that a list of models is the only working way. There is an open discussion about that specific issue.

so I can have ``sender=[]`` ? Thanks – Michael Mar 20 '14 at 00:33
Actually no, you cannot. The `receiver` decorator accepts only a signal (or a list of signals) and a single sender as kwarg. – Germano Mar 20 '14 at 08:52
