Django models with OneToOne relationships?

Question

Let\'s say I\'m using the default auth.models.User plus my custom Profile and Address models which look like this:

class P         


        

Answer 1

What about using 3 separate ModelForm. One for Address, one for User, and one for Profile but with :

class ProfileForm(ModelForm):
  class Meta:
    model = Profile
    exclude = ('user', 'address',)

Then, process these 3 forms separately in your views. Specifically, for the ProfileForm use save with commit=False to update user and address field on the instance :

# ...
profile_form = ProfileForm(request.POST)
if profile_form.is_valid():
  profile = profile_form.save(commit=False)
  # `user` and `address` have been created previously
  # by saving the other forms
  profile.user = user
  profile.address = address

Don't hesitate to use transactions here to be sure rows get inserted only when the 3 forms are valid.
