Several Django signal receivers in one module

I have separate python module for signal receivers, it's called signals.py and imported in ready() method of my AppConfig.

In this module I implemented post_save and post_delete signal receivers for specific model and registered them via decorator:

@receiver(post_save, sender=MyModel)
def generate_smth(sender, instance, created, **kwargs):
    ...

And it works fine. But, when I added to signals.py receivers of same signals in the same manner, but from different specific models:

@receiver(post_save, sender=AnotherModel)
def generate_smth(sender, instance, created, **kwargs):
    ...

My functions stopped to receive signals. But if I move receivers into separate python modules mymodel_signals.py and anothermodel_signals.py and import both modules in ready() then all of them works again.

Why it isn't possible to keep receivers in one module?

@receiver(post_save, sender=MyModel)
@receiver(post_save, sender=AnotherModel)
def generate_smth(sender, instance, created, **kwargs):
    if sender.__name__ = 'MyModel':
       # Bar
    else:
      # Foo

Do you want both functions to have the same behaviour? If yes, you can do:

def do_smth(sender, instance, created, **kwargs):
    ...

@receiver(post_save, sender=MyModel)
def generate_smth(sender, instance, created, **kwargs):
    do_smth(sender, instance, created, **kwargs)

@receiver(post_save, sender=AnotherModel)
def generate_another_smth(sender, instance, created, **kwargs):
    do_smth(sender, instance, created, **kwargs)
