Model Inheritance - And Signals

[Vitaly Babiy]

if I define a model called CustomModel and I attach attach a pre_save signal to it. Is there any way to have that signal be called any time model that extends CustomModel is being saved has that method saved.

I know i could do this by overriding the save method on CustomeModel but I was wondering if there is any way to do it with signals.

Thanks,

Try to connection handler without `sender` specified. And filter needed models inside it.

def my_handler(sender, **kwargs):
    if not isinstance(sender, CustomModel):
       return

signals.pre_save.connect(my_handler)
