Answer 1

First of all, you need to save your object.

Model form views provide a form_valid() implementation that saves the model automatically or simple save your form.

So call first form.save().

def form_valid(self,form):
    user = form.save()
    login(self.request, user, backend='django.contrib.auth.backends.ModelBackend')
    return redirect('company:home')
