OAuth2 custom basic user model - django

Question

I am using rest_framework_social_oauth2
I want to make a minimum change in oauth.User. Search to exchange AbstractBaseUser by AbstractUser and add PermissionMixin. But nothing works.
My app> models.py:
from django.db import models
from django.contrib.auth.models import AbstractUser, PermissionsMixin, UserManager
class MyUser(AbstractUser, PermissionsMixin):
country_code = models.CharField(max_length=10, blank=True)
objects = UserManager()
My settings.py:
AUTH_USER_MODEL ='userTest.MyUser'
As indicated by tutorials, not did makemigrations and migrate.
ERRO:
File "/Users/luisdemarchi/Git/django/.env/lib/python3.5/site-packages/django/db/models/manager.py", line 277, in get
self.model._meta.swapped,
AttributeError: Manager isn't available; 'auth.User' has been swapped for 'userTest.MyUser'

Answer 1

We managed. I'll put here a complete example for those who want to make an improvement in OAuth2.user. In our case we created the username automatically.
PS: Need create class AuthManager()
userTest(myApp) > models.py
import uuid as uuid
from django.contrib.auth.models import BaseUserManager, AbstractUser
from django.db import models
from rest_framework import exceptions
class AuthManager(BaseUserManager):
def create_user(self, email, username=None, password=None):
if not email:
raise exceptions.AuthenticationFailed('Users must have an username')
username = email.split("#")[0]
user = self.model(username=username)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, password, username=None):
user = self.create_user(email=email, password=password)
user.is_admin = True
user.save(using=self._db)
return user
class User(AbstractUser):
uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
is_test = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
objects = AuthManager()
userTest(myApp) > views.py
from rest_framework import viewsets
from apps.userTest.models import User
from apps.userTest.serializers import UserSerializer
class UserViewSet(viewsets.ReadOnlyModelViewSet):
queryset = User.objects.all()
serializer_class = UserSerializer
