class CustomUserAuth(object):

            if user.check_password(password):

    def get_user(self, user_id):

                return user
            return None
        except CustomUser.DoesNotExist:
            return None

我在settings.py文件中包含了以下行

    AUTH_USER_MODEL = 'user_management.CustomUser'

    AUTHENTICATION_BACKENDS = ('user_management.manager.CustomUserAuth',)

现在，为了进行故障排除，我运行python manage.py shell并导入表单

CustomUserCreationForm并将数据传递给它并尝试保存它。我也有同样的错误

Answer 1

不确定这是否相关，但您是否在def get_full_name(self)中正确获取了用户配置文件：

a=UserProfile.objects.get(email_id=self.id)

但是，我没有看到在您的类userprofile中指定email_id。您指定了email，并且这个类是从models.model子类的，默认情况下，我希望只有一个id列而不是email_id，除非您更改了它。

只是一个想法。
