i get this error when i try to access my version of 'CustomUser' model on the admin site(i have shortened it for clarity): no such column: app_name_publicprofile.user_ptr_id. Here is my model:

class PublicProfile(User):
    sex = models.CharField(max_length=100,choices=settings.SEX_CHOICES,
verbose_name='sex')
    phone_num = models.IntegerField(verbose_name='phone number')
    id_num = models.IntegerField(verbose_name='id number')
    age = models.DateField(verbose_name='date of birth')
    occupation = models.CharField(max_length= 20,
verbose_name='occupation')
    picture = models.ImageField(upload_to ='user_profile_images',
verbose_name='user photo')

    objects = UserManager()

but i can add users in the admin site. Any ideas?

Hi Scott, liked the inheritance but can anyone suggest how I can make an attribute of the child model required, if it is inheriting the User class without saving the user if the instance of the child model is not saved? eg.

class Customer(User):
organization = models.CharField(max_length=80, unique = True)
address = models.CharField(max_length=80)
.
..
objects = UserManager()

If in the admin.py, model Customer is registered, on execution, we get the user creation form, with password after saving it, we exit from the module. We are able to see that the user exists in the django Auth, even if the Customer is not yet created. How do I override the save of the User class. Also I need to create other users for the application the normal way. Please suggest

Ammara – see this post for a variation that deals with the Pasword not being encrypted and also the admin user not using this class but instead the original User.
http://www.kolios.dk/2010/01/22/how-to-extend-django-user-class-and-change-authentication-middleware/
Also see here for a more elegant solution for User override using User classname instead of CustomUser and Admin fix.
http://nigel.jp/2011/06/django-user-authentication-and-extending-the-user-model/

However you need to mix all three approaches to solve the problems in any one of them.
Would be great if this post was updated (or a new post replacing it) to reflect the best way to do all of this… (IMHO)
Thanks Scott for getting this started… Please consider doing an update and straighteneing all the wiggles out…

I have used the inheritence method to build a CustomUser class. Apparently its working absolutely fine but when I create a new user from admin, its password is not being encoded and as a result, I am unable to login with the newly created user. However, login action do not produce any error on the screen but the user is not being redirected to its home page. When I try to update the user from admin site. the password is being displayed in plain text and not in the encded format.

thanks in advance for any help. I am really stuck!!!

Hi all!
As the user comment 36, i got the problem with the passwords. They are not encryptated, so i had to override the save method.
Btw, i´m adding users only in admin interface, so, i´ve created a defaultAdmin to this.

In admin.py:

class defaultAdminModel(admin.ModelAdmin):
	def save_model(self, request, obj, form, change):
		obj.set_password(obj.password)
		obj.save()

Now, the others admin classes:
class AdminLocaisAtendimento(defaultAdminModel):

Thanks ! ;)
