Answer 1

You need to specify the model attribute (or the queryset or get_queryset) of the CreateView:

class SignUpView(CreateView):
    model = User
    from_class = SignUpForm
    success_url = reverse_lazy('home')
    template_name = 'common/register.html'

Answer 2

Form is wrongly spelt in the SignUpView class.Fix it and it should work fine.

Answer 3

Check the spelling of the information after class instantiation.

from django.contrib.auth.forms import UserCreationForm
from django.urls import reverse_lazy
from django.views import generic

class SignUpView(generic.CreateView):
    form_class = UserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'registration/signup.html'

I made the mistake of spelling "form_class" as "from_class".
