'UserProfile' object has no attribute 'id' - django

Question

I have an update form, whem i press updated for the form to update the user profile it I get the error "'UserProfile' object has no attribute 'id'"
my models is:
from django.db import models
from django.db.models.signals import post_save
from django.dispatch import receiver
class UserProfile(models.Model):
user = models.OneToOneField(User, related_name="custom_user_profile", primary_key=True)
organization = models.CharField(max_length=100, default='', blank=True)
address_line_1 = models.CharField(max_length=100, default='', blank=True)
address_line_2 = models.CharField(max_length=100, default='', blank=True)
city = models.CharField(max_length=100, default='', blank=True)
state = models.CharField(max_length=100, default='', blank=True)
post_code = models.CharField(max_length=100, default='', blank=True)
country = models.CharField(max_length=100, default='', blank=True)
def __unicode__(self):
return self.user.username
#receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
if created:
profile, new = UserProfile.objects.get_or_create(user=instance)
and my views is:
from django.shortcuts import render_to_response
from django.shortcuts import HttpResponseRedirect
from django.template import RequestContext
from django.core.context_processors import csrf
from django.contrib.auth.decorators import login_required
from user_profile.models import UserProfile
from django.contrib.auth.models import User
from forms import UserProfileForm
from django.shortcuts import redirect
#login_required
def update_profile(request):
userProfile = UserProfile.objects.get(user=request.user)
form = UserProfileForm(initial={
'organization':userProfile.organization,
'address_line_1':userProfile.address_line_1,
'address_line_2':userProfile.address_line_2,
'city':userProfile.city,
'state':userProfile.state,
'post_code':userProfile.post_code,
'country':userProfile.country,
})
return render_to_response('user_profile/update_profile.html', {'form':form}, RequestContext(request))
#login_required
def profile(request, profile_id):
if profile_id == "0":
if request.user.is_authenticated:
userProfile = UserProfile.objects.get(user=request.user)
else:
userProfile = UserProfile.objects.get(pk=profile_id)
return render_to_response('user_profile/profile.html', {'userProfile':userProfile}, RequestContext(request))
#login_required
def send_update_profile(request):
if request.method == 'POST':
form = UserProfileForm(request.POST)
if form.is_valid():
userProfile = UserProfile.objects.get(user=request.user)
organization = form.cleaned_data['organization']
userProfile.organization = organization
address_line_1 = form.cleaned_data['address_line_1']
userProfile.address_line_1 = address_line_1
address_line_2 = form.cleaned_data['address_line_2']
userProfile.address_line_2 = address_line_2
city = form.cleaned_data['city']
userProfile.city = city
state = form.cleaned_data['state']
userProfile.state = state
post_code = form.cleaned_data['post_code']
userProfile.post_code = post_code
country = form.cleaned_data['country']
userProfile.country = country
userProfile.save()
return redirect('/user/profile/' + str(userProfile.id))
else:
form = UserProfileForm()
return redirect('/user/send_update_profile/')
I can not work out why. One thing is that in admin.py, if i try to add 'id' as list display. An error occurs saying that there is no id in the user profile I am creating. Though, i thought an id field is automatically created when a model is created.
Any suggestions?

Django gives each model an automatic primary key field named id, unless you specify a primary key yourself. In your case, your model does not have an id field, because you have made user the primary key.
class UserProfile(models.Model):
user = models.OneToOneField(User, related_name="custom_user_profile", primary_key=True)
You could change the code to use the userProfile.user_id. Another option is to use the pk shortcut to access the primary key.
return redirect('/user/profile/' + str(userProfile.pk))
