Django post_save signal on parent class with multi-table inheritance

post_save.connect(my_handler, ParentClass)
# connect all subclasses of base content item too
for subclass in ParentClass.__subclasses__():
    post_save.connect(my_handler, subclass)

have a nice day!

Check out: https://code.djangoproject.com/ticket/9318 It appears that most propagate the signal to the super in the subclass.
