我创建了一个自定义用户模型，用电子邮件替换用户名，并希望将其与Djoser和React一起使用。
但当我尝试进行迁移时，我会遇到这个错误(更多详细信息如下(：
TypeError: Abstract base class containing model fields not permitted for proxy model 'TokenProxy'.
models.py:
from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin
class UserAccountManager(BaseUserManager):
def create_user(self, email, name, password=None):
if not email:
raise ValueError('Users must have an email address')
email = self.normalize_email(email)
user = self.model(email=email, name=name)
user.set_password(password)
user.save()
return user
def create_superuser(self, email, password, name, **extra_fields):
"""Create and save a SuperUser with the given email and password."""
extra_fields.setdefault('is_staff', True)
extra_fields.setdefault('is_superuser', True)
if extra_fields.get('is_staff') is not True:
raise ValueError('Superuser must have is_staff=True.')
if extra_fields.get('is_superuser') is not True:
raise ValueError('Superuser must have is_superuser=True.')
serializers.py
from djoser.serializers import UserCreateSerializer, UserSerializer
from django.contrib.auth import get_user_model
User = get_user_model()
class UserCreateSerializer(UserCreateSerializer):
class Meta(UserCreateSerializer.Meta):
model = User
fields = ('id', 'email', 'name', 'password')
urls.py
urlpatterns = [
path('auth/', include('djoser.urls')),
path('auth/', include('djoser.urls.jwt')),
]
urlpatterns += [re_path(r'^.*', TemplateView.as_view(template_name='index.html'))]
当我尝试进行迁移时，会出现以下错误：

请检查django-rest-framework中的以下PR。
作为修复程序，您可以在djoser之前将rest_framework.authtoken添加到INSTALLED_APPS中。
