Django multiple User profiles/subprofiles

Question

I am trying to create an intranet/extranet with internal/external user-specific profiles, with a common generic profile. I've looked at several answers on this site, but none specifically address what I'm looking to do. Below are the (stripped down) files I have so far.

What's the best way to create a profile model, with subprofiles for each user type? I'm trying not to require a custom authentication backend if at all possible.

I have a solution I dont Know if its the best but see it:

models.py

from django.db import models
from django.contrib.auth.models import User

class Pollster(models.Model):
    """docstring for Polister"""
    user   = models.OneToOneField(User, related_name = 'polister', unique=True)
    cedule = models.CharField( max_length = 100 ) 

class Respondent(models.Model):
    """ """
    born_date   = models.DateField( verbose_name=u'fecha de nacimiento' )
    cedule      = models.CharField( max_length = 100, verbose_name=u'cedula' ) 
    comunity    = models.CharField( max_length = 100, verbose_name=u'comunidad')
    phone       = models.CharField( max_length = 50, verbose_name=u'telefono')
    sanrelation = models.TextField( verbose_name =u'Relacion con SAN')
    user        = models.OneToOneField( User, related_name = 'respondent')

I create a MiddleWare: so

i create middleware.py

from django.contrib.auth.models import User
from encuestas.models import Pollster, Respondent

class RequestMiddleWare(object):
    """docstring for """
    def process_request(self,request):
        if isPollster(request.user):
            request.user.userprofile = Pollster.objects.get( user = request.user.id)
        elif isRespondent(request.user):
            request.user.userprofile = Respondent.objects.get(user = request.user.id)   
        return None   

def isPollster(user):
    return Pollster.objects.filter(user=user.id).exists()

def isRespondent(user):
    return Respondent.objects.filter(user=user.id).exists()

and you need to configure settings.py for the middleware: add to MIDDLEWARE_CLASSES atribute:

'encuestas.middleware.RequestMiddleWare'

encuestas is my_app name middleware is the Middleware file RequestMiddleWare is the middleware class

You need a combination of storing additional information about users and model inheritance.

Basically, you'll need the generic User models we all know and either love or hate, and then you need a generic profile model that is your AUTH_PROFILE_MODULE setting.

That profile model will be a top-level model, with model subclasses for internal and extrernal users. You probably don't want an abstract model in this case since you'll need a common profile table to load user profiles from with User.get_profile().

So...I think the major thing you want to change is to make your Associate, External, etc. models inherit from your Profile model.
