Python 如何从身份验证中消除用户名

我想在我的应用程序中消除django auth中用户名的概念。我希望用户的

电子邮件

取代

用户名

。因此，我用下面的代码扩展了

AbstractBaseUser

class AuthUserManager(BaseUserManager):
    def create_user(self, email, password=None):
        if not email:
            raise ValueError("Users must have an email address")

        user = self.model(email=self.normalize_email(email),)
        user.is_active = True
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, password):
        user = self.create_user(email=email, password=password)
        user.is_staff = True
        user.is_superuser = True
        user.save(using=self._db)
        return user


class AuthUser(AbstractBaseUser, PermissionsMixin):
    alphanumeric = RegexValidator(r'^[0-9a-zA-Z]*$', message = "Only alphanumeric characters are allowed")


    email = models.EmailField(verbose_name='email address',unique=True, max_length=255)
    first_name = models.CharField(unique=True, max_length=20, validators=[alphanumeric])
    last_name = models.CharField(unique=True, max_length=20, validators=[alphanumeric])
    date_joined = models.DateTimeField(auto_now_add=True)
    is_active = models.BooleanField(default=True, null=False)
    is_staff = models.BooleanField(default=False, null=False)

    #custom fields
    company_name = models.CharField(max_length=100)
    telephone_number = models.CharField(max_length=100)
    website_url = models.CharField(max_length=100)

    objects = AuthUserManager()
    USERNAME_FIELD = 'email'
    #REQUIRED_FIELDS = ['first_name']

    def get_full_name(self):
        fullname = self.first_name + self.last_name
        return fullname

    def get_short_name(self):
        return self.email

    def __unicode__(self):
        return self.email

在我的serializers.py中，我有这个

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = AuthUser
        fields = ('email', 'first_name', 'last_name')

    def create(self, validated_data):
        user = AuthUser.objects.create(**validated_data)
        return user

    def update(self, instance, validated_data):
        instance.email = validated_data.get('email', instance.email)
        instance.first_name = validated_data.get('first_name', instance.first_name)
        instance.last_name = validated_data.get('last_name', instance.last_name)
        instance.save()
        return instance

但是，当我尝试注册时，会出现以下错误：

{
    "username": [
        "This field is required."
    ]
}

我做错了什么

在序列化程序中，您需要排除

username

字段，因为您是从

AbstractBaseUser

继承的，并且您仍然有“username”字段，所以添加此

exclude=（'username'，）

---

这种错误消息将来自表单。您使用的注册表单仍然依赖于

username

？我正在使用我的应用程序的REST API端点创建新用户。

username

字段不在

AuthUser

@cold中，他从AbstractBaseUser继承了它。

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = AuthUser
        fields = ('email', 'first_name', 'last_name')
        exclude = ('username',)

    def create(self, validated_data):
        user = AuthUser.objects.create(**validated_data)
        return user
