Django User model, adding function

Question

I want to add a new function to the default User model of Django for retrieveing a related list of Model type.

Such Foo model:

class Foo(models.Model):
    owner = models.ForeignKey(User, related_name="owner")
    likes = models.ForeignKey(User, related_name="likes")

........

    #at some view
    user = request.user
    foos= user.get_related_foo_models()

How can this be achieved?

Answer 1

You can add a method to the User

from django.contrib import auth
auth.models.User.add_to_class('get_related_foo_models', get_related_foo_models)

Make sure, you have this code within the models.py or some other file which gets imported in the startup of django.
