Best Solution i have found for the Extending User model and Update UserProfile.....But can you provide support to change the admin panel "UserProfile object" into some other attribute like "username"

skpace to do that, in the UserProfile class you need to add following codes

def __str__(self):
return self.user.username

By the way, thanks for solution.

Would I access the edit page by entering the user id in the url? If so I get this error:

File "....\views.py", line 32, in edit_user
if request.user.is_authenticated() and request.user.id == user.id:
TypeError: 'bool' object is not callable

thank you

Also another error is
if request.user.is_authenticated() and request.user.id == user.id:
TypeError: 'bool' object is not callable

Also another error is
if request.user.is_authenticated() and request.user.id == user.id:
TypeError: 'bool' object is not callable

@trnguyen1510 I believe you don't need to use "is_authenticated" as a method call but rather a property, i.e. "request.user.is_authenticated"(NOT "request.user.is_authenticated()")
