Django - Overriding the Model.create() method?

Question

The Django docs only list examples for overriding save() and delete(). However, I\'d like to define some extra processing for my models onl

Answer 1

This is old, has an accepted answer that works (Zach's), and a more idiomatic one too (Michael Bylstra's), but since it's still the first result on Google most people see, I think we need a more best-practices modern-django style answer here:

from django.db.models.signals import post_save

class MyModel(models.Model):
    # ...
    @classmethod
    def post_create(cls, sender, instance, created, *args, **kwargs):
        if not created:
            return
        # ...what needs to happen on create

post_save.connect(MyModel.post_create, sender=MyModel)

The point is this:

1. use signals (read more here in the official docs)
2. use a method for nice namespacing (if it makes sense) ...and I marked it as @classmethod instead of @staticmethod because most likely you'll end up needing to refer static class members in the code

Even cleaner would be if core Django would have an actual post_create signal. (Imho if you need to pass a boolean arg to change behavior of a method, that should be 2 methods.)
