实现自定义用户模型后无法登录 Django 管理面板

Question

我已经完成了自定义用户模型，但我无法使用我创建的超级用户帐户登录管理面板。是什么原因导致此问题？我该如何解决？任何帮助或指导将不胜感激。

用户/user.py

from django.contrib.auth.models import AbstractUser
from django.db import models
from ..managers.user import UserManager

class User(AbstractUser):
    objects = UserManager()

经理/用户.py

from django.contrib.auth.models import BaseUserManager


class UserManager(BaseUserManager):

    def create_superuser(self, username, email=None, password=None, **extra_fields):
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)

        return self.create_user(username, email, password, **extra_fields)

    def create_user(self, email, username=None, password=None, **extra_fields):
        if not username:
            raise ValueError('The username field must set')

        email = self.normalize_email(email)
        user = self.model(username=username, email=email, **extra_fields)
        user.set_password(password)
        user.save(using=self.db)

        return user

用户/序列化器.py

from django.contrib.auth import get_user_model
from django.contrib.auth.password_validation import validate_password
from rest_framework import serializers  # type: ignore # noqa: I201

User = get_user_model()


class UserReadSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = ('id', 'username')


class UserWriteSerializer(serializers.ModelSerializer):
    password = serializers.CharField(validators=[validate_password], write_only=True)

    class Meta:
        model = User
        fields = ('password', 'username')

    def create(self, validated_data):
        password = validated_data.pop('password')
        username = validated_data.get('username')
        user = User.objects.create_user(username=username, password=password)

        return user

问题可能出在这里，您是否尝试过使用电子邮件作为用户名登录

    return self.create_user(username, email, password, **extra_fields)

def create_user(self, email, username=None, password=None, **extra_fields):

根据上面的代码，您在调用方法 self.create_user 时交换了用户名和电子邮件字段。 解决方案：

    return self.create_user(email, username, password, **extra_fields)

def create_user(self, email, username=None, password=None, **extra_fields):
