django - Consolidating multiple post_save signals with one receiver

Question

So I read the Django source code (post 1.5) that you can now register multiple multiple signals to a receiver function:

def receiver(signal, **kwargs):
    """
    A decorator for connecting receivers to signals. Used by passing in the
    signal (or list of signals) and keyword arguments to connect::

        @receiver(post_save, sender=MyModel)
        def signal_receiver(sender, **kwargs):
            ...

        @receiver([post_save, post_delete], sender=MyModel)
        def signals_receiver(sender, **kwargs):
            ...

    """
    ... implementation code...

However, I want to register multiple post_save signals from different senders to the same function. Right now, I just call

post_save.connect(fn_name, model_name)

for each model that I have. Is there a better way to do this with the new Django 1.5 @receiver decorator capability?

Answer 1

You can do that using the @receiver decorator:

from django.dispatch import receiver

@receiver(post_save, sender=Model1)
@receiver(post_save, sender=Model2)
@receiver(post_save, sender=Model3)
def my_signal_handle(sender , **kwargs)
    # some code here
