Here's my setup on django 3.0.10:
{{{
class MyModel(models.Model):
pass
@receiver(post_save, sender=MyModel)
@receiver(post_delete, sender=MyModel)
def process_stuff(sender, instance, **kwargs):
# to some magic
pass
}}}
When I want to disconnect the post_save signal like this:
{{{
from django.db.models import signals
signals.post_save.disconnect(
receiver=process_stuff,
sender=MyModel,
}}}
... it does not work.
If I comment out the second decorator with `post_delete`, it works.
If I split this up and use two different functions, it works as well.
I posted at StackOverflow (https://stackoverflow.com/q/64102708/1331671)
and in some django groups, but no replies yet.
Seems like a bug to me :(
