PODjango-profiles custom create/edit modelForm not saving properly

copied!<p>Summary:</p> <pre><code>u = self.instance.user </code></pre> <p>in</p> <pre><code>def save(self, *args, **kwargs): u = self.instance.user u.first_name = self.cleaned_data['first_name'] u.last_name = self.cleaned_data['last_name'] u.save() return super(ProfileForm, self).save(*args, **kwargs) </code></pre> <p>is causing a problem because self.instance doesn't exist. But yet this is how it is done in other examples, where it seems to work. What am I missing?</p> <p>Read on for more info -></p> <p>I am using both django-registration and django-profiles. For the purposes of just getting it to work, I have not added any extra fields to the profile model (the one that extends User). So far it looks like this:</p> <pre><code>class sumaConnectUser(models.Model): user = models.ForeignKey(User) def __unicode__(self): return self.user.first_name + " " + self.user.last_name def get_absolute_url(self): return ('profiles_profile_detail', (), { 'username': self.user.username }) get_absolute_url = models.permalink(get_absolute_url) </code></pre> <p>My understanding is as of now, my user "profile" should just include the fields that come with the contrib.auth model User. ( first name, last name etc)</p> <p>In my urls.py, I pass in my custom form for the creation and edit of the profiles-</p> <pre><code>(r'^profiles/edit', 'profiles.views.edit_profile', {'form_class': ProfileForm, }), (r'^profiles/create', 'profiles.views.create_profile', {'form_class': ProfileForm, }), (r'^profiles/', include('profiles.urls')), </code></pre> <p>Finally, here is my profile form-</p> <pre><code>from suma.sumaconnect.models import sumaConnectUser from django import forms from django.contrib.auth.models import User class ProfileForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(ProfileForm, self).__init__(*args, **kwargs) try: self.fields['first_name'].initial = self.instance.user.first_name self.fields['last_name'].initial = self.instance.user.last_name except User.DoesNotExist: pass first_name = forms.CharField(label="First Name") last_name = forms.CharField(label="Last Name") class Meta: exclude = ('user',) model = sumaConnectUser def save(self, *args, **kwargs): u = self.instance.user u.first_name = self.cleaned_data['first_name'] u.last_name = self.cleaned_data['last_name'] u.save() return super(ProfileForm, self).save(*args, **kwargs) </code></pre> <p>My goal is to allow the user to edit their first name and last name as part of the profile edit, but not their username and password.</p> <p>I thought about replacing</p> <pre><code>u = self.instance.user </code></pre> <p>with</p> <pre><code>u = User.objects.get(user = self.cleaned_data['username']) </code></pre> <p>but this would require me to include a username = forms.CharField on the page which I do not want to display. As far as I understand, when I come to the create profile or edit profile page, I should be automatically editing the profile associated with the user which I am logged in as.</p> <p>By the time I come to this create or edit user page, the user model already exists, but the profile doesn't. Is this the cause of the problem? I think I am misunderstanding something major, and I would greatly appreciate any pointers as to where I am going wrong. Thanks!</p>
