python - 如何修复 'Meta.fields'不得包含非模型字段名称: username for django graphene authentication endpoint

Question

在我的 Django 应用程序中，我创建了使用电子邮件作为用户名的客户用户模型。

class UserManager(BaseUserManager):
    """Define a model manager for User model with no username field."""

    use_in_migrations = True

    def _create_user(self, email, password, **extra_fields):
        """Create and save a User with the given email and password."""
        if not email:
            raise ValueError('The given email must be set')
        email = self.normalize_email(email)
        user = self.model(email=email, **extra_fields)
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_user(self, email, password=None, **extra_fields):
        """Create and save a regular User with the given email and password."""
        extra_fields.setdefault('is_staff', False)
        extra_fields.setdefault('is_superuser', False)
        return self._create_user(email, password, **extra_fields)

    def create_superuser(self, email, password, **extra_fields):
        """Create and save a SuperUser with the given email and password."""
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)

        if extra_fields.get('is_staff') is not True:
            raise ValueError('Superuser must have is_staff=True.')
        if extra_fields.get('is_superuser') is not True:
            raise ValueError('Superuser must have is_superuser=True.')

        return self._create_user(email, password, **extra_fields)


class User(AbstractUser):
    username = None
    email = models.EmailField(_('email address'), unique=True,)

    user_id = models.UUIDField(
        default=uuid4,
        unique=True,
    )

我正在使用 Graphite 烯作为 API。对于身份验证端点，我遵循以下步骤， https://django-graphql-auth.readthedocs.io/en/latest/quickstart/

我一直遇到以下错误，

sports_league-web-1  |   File "/usr/local/lib/python3.10/site-packages/django_filters/filterset.py", line 71, in __new__
sports_league-web-1  |     new_class.base_filters = new_class.get_filters()

sports_league-web-1  |     raise TypeError(
sports_league-web-1  | TypeError: 'Meta.fields' must not contain non-model field names: username

请告诉我我在这里做错了什么。如果需要任何其他详细信息，请告诉我。

这就是我解决这个问题的方法。

通过添加以下内容来修改应用设置文件，

from graphql_auth.settings import DEFAULTS

DEFAULTS['LOGIN_ALLOWED_FIELDS'] = ['email']
DEFAULTS['REGISTER_MUTATION_FIELDS'] = ['email']
DEFAULTS['USER_NODE_FILTER_FIELDS'] = {
    'email': ['exact'],
    'is_active': ['exact'],
    'status__archived': ['exact'],
    'status__verified': ['exact'],
    'status__secondary_email': ['exact'],
}
GRAPHQL_AUTH = DEFAULTS
