The fix is to adjust 1.11 django.contrib.auth.forms as follows:
Line 12 - comment it right out
Line 88 - change User to UserModel
Line 128 - change User to UserModel

I have a custom user based on AbstractUser plus a UserProfile model as
follows:
#common.models from django.conf import settings from
django.contrib.auth.models import AbstractUser, Group, UserManager
from django.db import models from django.utils.encoding import
python_2_unicode_compatible @python_2_unicode_compatible class
User(AbstractUser): objects = UserManager() class Meta: abstract =
False def __str__(self): grps = u'' superuser = u'' if self.is_staff:
superuser = u' [Staff]' if self.is_superuser: superuser = u'
[Superuser]' if not self.is_active: superuser += u' [Inactive]' groups
= Group.objects.filter(user=self).order_by('name') if groups: grps =
u', '.join(grp.name for grp in groups) if grps: grps = u' (%s)' % grps
grps += superuser return u'%s%s' % (self.username, grps) def
save(self, *args, **kwargs): super(User, self).save(*args, **kwargs) #
not sure whether to use the post-save signal or just save it here
profile = UserProfile.objects.get_or_create(user=self)[0]
profile.save() @python_2_unicode_compatible class
UserProfile(models.Model): user = models.OneToOneField(
settings.AUTH_USER_MODEL, related_name='userprofile',
on_delete=models.CASCADE, ) ... created =
models.DateTimeField(auto_now_add=True) modified =
models.DateTimeField(auto_now=True) class Meta: verbose_name = 'user
profile' verbose_name_plural = 'user profile' def __str__(self):
return u'%s' % self.user
The error occurs when I click [Register] with a new user via the
following view:
#common.views from django.contrib.auth import login, authenticate from
django.contrib.auth.forms import UserCreationForm from
django.shortcuts import render, redirect def register(request): if
request.method == 'POST': form = UserCreationForm(request.POST) if
form.is_valid(): form.save() username =
form.cleaned_data.get('username') raw_password =
form.cleaned_data.get('password1') user =
authenticate(username=username, password=raw_password) login(request,
user) return redirect('common.views.homepage') else: form =
UserCreationForm() return render(request, 'register.html', {'form':
form})
For completeness here is the template:
#register.html {% extends 'base_site.html' %} {% block content %}
<h2>Register</h2> <form method="post"> {% csrf_token %} {{ form.as_p
}} <button type="submit">Register</button> </form> {% endblock %}
