Problems updating user profiles.

Question

Working out editing profiles and ran into a little trouble! The following piece of code succesfully updates the mug_shot column in the user profile, but also erases all the other column data for that particular record. It's weird because Django is supposed to automatically distinguish between updates/saves. What's weirder is that everywhere else updates/saves seem to work fine.

I'm kind of at a loss.

@login_required
def add_mugshot(request):
 user = request.user
 profile = UserProfile.objects.get(user=user)
 if request.method == 'POST':
  profile_form = ProfileForm(request.POST, request.FILES, instance=profile)
  if profile_form.is_valid():
   new_profile = profile_form.save(commit=False)
   new_profile.user = user
   new_profile.save()

   return HttpResponseRedirect('/accounts/profile/')
 else:
  profile_form = ProfileForm(instance=profile)

 return render_to_response('accounts/add_mugshot.html', 
  RequestContext(request, {
   'profile_form': profile_form}))

I wonder if this is something in your form template. If you aren't showing all of the fields, Django will interpret them as empty, and save your instance with empty fields.
