当我尝试登录时，sed密码和电子邮件id。它获取两个字段数据，但authenticate方法不返回任何数据。为此，我在设置文件中写入了

AUTH\u USER\u MODEL='register.Consultants'

，然后出现另一个错误，显示

AttributeError:type对象“Consultants”没有属性“REQUIRED\u FIELDS”

如何通过身份验证方法登录。为什么它不起作用

请在这方面帮助我

您有名为

MyUser

的自定义用户模型，但是在您的配置中，您引用了完全不同的

注册。顾问

-使用

MyUser

模型

从我可以看到的情况来看，每个用户都是顾问，所以为什么不简化所有代码并创建一个模型类

Consultants

，它将处理用户和配置文件信息：

class Consultant(AbstractBaseUser):
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,
    )

    first_name = models.CharField(max_length=255, blank=True, null=True)
    last_name = models.CharField(max_length=255, blank=True, null=True)
    username = models.CharField(max_length=255, blank=True, null=True)
    consul_pic = models.ImageField(upload_to="/homeDocuments/pro//Registration/consul_pic", blank=True, null=True)
    mobile_no = models.CharField(max_length=255, blank=True, null=True)
    country = models.IntegerField(validators=[MaxLengthValidator(11)], blank=True, null=True)
    state = models.IntegerField(validators=[MaxLengthValidator(11)], blank=True, null=True)
    city = models.IntegerField(validators=[MaxLengthValidator(11)], blank=True, null=True)
    experience = models.IntegerField(default=0, blank=True, null=True)
    skills = models.CharField(max_length=255, blank=True, null=True)
    education = models.CharField(max_length=255, blank=True, null=True)
    linkedin_id = models.CharField(max_length=255, blank=True, null=True)

    created_on = models.DateTimeField(auto_now_add=True, blank=True, null=True)
    last_updated_on = models.DateTimeField(auto_now=True, blank=True, null=True)
    last_login = models.DateTimeField(auto_now_add=True, blank=True, null=True)

    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = MyUserManager()

    USERNAME_FIELD = 'email'
    # REQUIRED_FIELDS = ['date_of_birth']

    def get_full_name(self):
        # The user is identified by their email address
        return self.email

    def get_short_name(self):
        # The user is identified by their email address
        return self.email

    def __unicode__(self):              # __unicode__ on Python 2
        return self.email

    def has_perm(self, perm, obj=None):
        "Does the user have a specific permission?"
        # Simplest possible answer: Yes, always
        return True

    def has_module_perms(self, app_label):
        "Does the user have permissions to view the app `app_label`?"
        # Simplest possible answer: Yes, always
        return True

    @property
    def is_staff(self):
        "Is the user a member of staff?"
        # Simplest possible answer: All admins are staff
        return self.is_admin

很少有离题评论：

is_staff标志在默认管理员实现中用于限制非超级用户对管理员的访问；如果您希望使用任何权限，例如某些用户将无法编辑其他用户数据，或者您希望删除其中某些用户的某些记录的权限（仅使用超级用户标志），则这一点非常重要-每个用户都可以做任何事
为什么决定手动管理主键？这不仅是错误的代码，而且在同时有多个请求时可能会产生错误
按照惯例，类名应该是单数的——一个记录就是一个顾问
如果您使用一对一-将其用作主键-只是为了简化代码并更好地理解其中的内容
如果您引用其他模型作为外键或一对一-您仍然引用整个模型，而不是它的属性，因此
```
user\u name=models.OneToOneField（MyUser）
```
应该是
```
user=models.OneToOneField（MyUser）
```
，这样您访问
```
consultant\u x.user.name
```
我不知道你为什么把国家、州和城市作为整型字段。。。加上MaxLengthValidator将无法处理整数整数没有len（）方法
对于日期时间字段，有
```
auto\u now\u add
```
和
```
auto\u now
```
标志-比
```
default
```

您是否尝试将必填字段添加到该模型中？如果通过添加必填文件来完成身份验证，则我肯定要添加必填文件我要验证我的用户在您的模型中取消注释

必填字段=['出生日期]

。你需要有那个领域。
