我遵循了有关如何通过使用电子邮件而不是普通用户名来允许Django身份验证的教程，但是，他们没有提到如何在管理页面中注册新的自定义用户模型！我是Django的真正初学者，所以我将尽可能多地提供详细信息！到目前为止，这是我的代码：

managers.py

from django.contrib.auth.models import BaseUserManager

class CustomUserManager(BaseUserManager):

    def create_user(self,email,password=None,**kwargs):
        if not email:
            raise ValueError('Email field is required')

        email = self.normalize_email(email)
        user = self.model(email=email,**kwargs)
        user.set_password(password)
        user.save()
        return user

    def create_superuser(self,password,**extra_fields):
        extra_fields.setdefault('is_staff',True)
        extra_fields.setdefault('is_superuser',True)
        extra_fields.setdefault('is_active',True)
        return self.create_user(email,**extra_fields)

models.py

from django.db import models
from django.contrib.auth.models import AbstractBaseUser
from django.contrib.auth.models import PermissionsMixin
from django.utils.translation import gettext_lazy as _

from .managers import CustomUserManager

class CustomUser(AbstractBaseUser,PermissionsMixin):
    email = models.EmailField(unique=True,null=True)
    is_staff = models.BooleanField(
        _('staff status'),default=False,help_text=_('Designates whether the user can log into this admin site.'),)
    is_active = models.BooleanField(
        _('active'),default=True,help_text=_(
            'Designates whether this user should be treated as active. ''unselect this instead of deleting accounts.'
        ),)

    username_FIELD = 'email'
    objects = CustomUserManager()

    class Meta:
        verbose_name = _('user')
        verbose_name_plural = _('users')

    def get_full_name(self):
        return self.email

    def get_short_name(self):
        return self.get_full_name()

    def __str__(self):
        return self.email

admin.py

from django.contrib import admin

# Register your models here.
