What would you like to do?
Example to illustrate a problem I'm having with multi-table inheritance for user profiles in django and Userena
# This is the form to sign up a Spam Type Person
from django import forms
from userena.forms import SignupFormTos
from . models import CommonProfile, SpamProfile
class SpamSignupForm(SignupFormTos):
"""signup a Spam Person"""
common_field = forms.CharField(label='what is your quest')
spam_field = forms.CharField(label='what kind of spam are you')
def clean(self):
cleaned_data = super(SpamSignupForm,self).clean()
#do stuf, same idea for clean_<field>
return cleaned_data
def save(self):
"""Save the SpamProfile"""
user = super(SpamSignupForm,self).save()
common_profile = user.get_profile()
spam_profile = SpamProfile(commonprofile_ptr=common_profile)
spam_profile.spam_field = self.cleaned_data['spam_field']
return spam_profile
# This is an example of how i've attempted to get
# multiple user profiles working with Userena
from django.contrib.auth.models import User
from django.db import models
from userena.models import UserenaLanguageBaseProfile
class CommonProfile(UserenaLanguageBaseProfile):
"""Common fields for 2 user profiles: Spam and Eggs"""
user = models.OneToOneField(User)
common_field = models.CharField(max_length=100)
def is_spam(self):
"""Find out if this is a Spam user"""
return True
except SpamProfile.DoesNotExist:
return False
def get_real_type(self):
"""return the real model"""
if self.is_spam:
return self.spamprofile
return self.eggsprofile
class SpamProfile(CommonProfile):
spam_field = models.CharField(max_length=20)
class EggsField(CommonProfile):
eggs_field = models.SmallIntegerField()

Example code for a problem I'm having using Userena and multi-table inheritance to have multiple profile types. When I do this, no data gets populated in the SpamProfile table, and all users are of type CommonProfile, which should not be aloud.

I've seen you asked this on SO:
Could you please tell us if you have found a solution? If positive it would be very kind of you to share it.
I'm also struggling with it!
