Enhance the django user admin with enforced unique emails, better filters and list items, and user profiles editable inline.
from django.contrib import admin

def upgrade_user_admin(UserProfile=None, unique_email=False,

"""This helper function enhances the built in auth.user admin as follows:
- If given a UserProfile class, allow it to be edited inline in the
user admin.
- Add "make active" and "make inactive" actions to the actions dropdown
- Alters list_display if provided
- Add date joined and last login filters
- Add the email field to the first step when creating a user
- Optionally enforce unique emails at the form level
Usage:
from upgrade_user_admin import upgrade_user_admin
from myapp.models import MyUserProfile
upgrade_user_admin(
UserProfile=MyUserProfile, unique_email=True,
list_display=['email', 'first_name', 'last_name'])
