Answer 1

This is an update of @Lakshman Prasad's answer. But a full example:

create a file monkey_patching.py in any of your apps::

#app/monkey_patching.py
from django.contrib.auth.models import User 

def get_user_name(self):
    if self.first_name or self.last_name:
        return self.first_name + " " + self.last_name
    return self.username

User.add_to_class("get_user_name",get_user_name)

and import it in app's __init__.py file. ie::

#app/__init__.py
import monkey_patching
