Change Django Auth Group Ordering

Following on from my last post on changing the behaviour of the Django contrib auth models. Another thing you might like to do is to change the default ordering:

from django.contrib.auth.models import User
User._meta.ordering = ['-email']

from django.contrib.auth.models import Group
Group._meta.ordering = ['-id']

Change Django Auth User Meta

Sometimes it can be helpful to change the default behaviour of the Auth User model or other models built into Django.
One use case might be if you want to change the length of the username field in the Auth User model to allow for longer usernames (e.g. an email address).

There is a simple way to change the max length attribute:

from django.contrib.auth.models import User
User._meta.get_field_by_name('username')[0].max_length=75

Django foo » meta
