1. Remove user field from rendered form (using exclude or fields, https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#selecting-the-fields-to-use )

   class CandidateForm(forms.ModelForm):
       class Meta:
           model = Candidate
           exclude = ["user"]
   

2. Find user profile and set user field in the create view.

   class CandidateCreateView(CreateView):
       ...
       def form_valid(self, form):
           candidate = form.save(commit=False)
           candidate.user = UserProfile.objects.get(user=self.request.user)  # use your own profile here
           candidate.save()
           return HttpResponseRedirect(self.get_success_url())
