admin.py:

from django.contrib import admin .models import profile # register models here.  admin.site.register(profile) # register models here.

any appreciated.

you have set relation manually view should this:

    if form.is_valid() , profile_form.is_valid():         user_object = form.save()         = profile_form.save(commit=false)         a.user = user_object         a.save()         return redirect('login')
