Django User Registration with custom user model - django

Question

I want to create a signup form for a Django custom user model using abstractuser. I don't want anything special, just the ability to later on add custom fields if needed.
I understand from the docs that I need to:
set AUTH_USER_MODEL
define a custom user model by subclassing AbstractUser
define a custom model manager by subclassing UserManager
subclass UserCreationForm and UserChangeForm
Here's my current code:
My settings.py:
AUTH_USER_MODEL = 'users.CustomUser'
My models.py:
from django.contrib.auth.models import AbstractUser, UserManager
class CustomUserManager(UserManager):
pass
class CustomUser(AbstractUser):
objects = CustomUserManager()
My forms.py:
from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import CustomUser
class CustomUserCreationForm(UserCreationForm):
class Meta(UserCreationForm.Meta):
model = CustomUser
fields = UserCreationForm.Meta.fields
class CustomUserChangeForm(UserChangeForm):
class Meta:
model = CustomUser
fields = UserChangeForm.Meta.fields
My admin.py:
from django.contrib import admin
from django.contrib.auth import get_user_model
from django.contrib.auth.admin import UserAdmin
from .forms import CustomUserCreationForm, CustomUserChangeForm
from .models import CustomUser
class CustomUserAdmin(UserAdmin):
model = CustomUser
add_form = CustomUserCreationForm
form = CustomUserChangeForm
admin.site.register(CustomUser, CustomUserAdmin)
My views.py:
from django.urls import reverse_lazy
from django.views import generic
from .forms import CustomUserCreationForm
class SignUp(generic.CreateView):
form_class = CustomUserCreationForm
success_url = reverse_lazy('login')
template_name = 'signup.html'
Upon submission of the signup form get the error message:
OperationalError at /users/signup/
no such table: users_customuser
I've nuked my database and done makemigrations and then migrate from scratch. Something is wrong with my form and perhaps admin, too.

See the Django docs about rewriting the User model: Referencing the User Model
However, if your user model extends AbstractBaseUser, you’ll need to define a custom ModelAdmin class.
In admin.py, you should get the user model from django.contrib.auth:
admin.py:
from django.contrib.auth import get_user_model
Class MyCustomModelAdmin...
CustomUser = get_user_model()
admin.site.register(CustomUser, MyCustomModelAdmin)
EDIT: I think the issue may be with your use of UserCreationForm.
My forms.py:
from django import forms
from .models import CustomUser
class CustomUserCreationForm(UserCreationForm):
class Meta:
model = CustomUser
fields = [list fields here]
