如何使用django从我选择的特定数据库表中登录用户

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',  # 数据库引擎
        'NAME': 'your_database_name',  # 数据库名
        'USER': 'your_username',  # 数据库用户名
        'PASSWORD': 'your_password',  # 数据库密码
        'HOST': 'your_host',  # 数据库主机
        'PORT': 'your_port',  # 数据库端口
    }
}

python manage.py startapp your_app_name

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager

class CustomUserManager(BaseUserManager):
    def create_user(self, email, password=None):
        if not email:
            raise ValueError('The Email field must be set')
        
        user = self.model(email=self.normalize_email(email))
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, password=None):
        user = self.create_user(email, password)
        user.is_admin = True
        user.save(using=self._db)
        return user

class CustomUser(AbstractBaseUser):
    email = models.EmailField(unique=True)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = CustomUserManager()
