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):
    \         


        

Answer 1

You can skip model_name and you will connect to all models post_save. Then you can filter if you are in right model in the handler:

post_save.connect(foo)

def foo(sender, **kwargs):
    if sender not in [FooModel, BarModel]:
        return
    ... actual code ...

or you can filter based on field in model:

def foo(sender, **kwargs):
    if not getattr(sender, 'process_by_foo', False):
        return
    ... actual code ...
