Django Rest Framework：如何通过non_field_errors设置自定义名称？

Question

我正在验证在我的网站上注册的用户是否给我唯一的地址（城市，街道，街道号码等），如果该地址不是唯一的，那么我正在提出serializers.ValidationError：

class UserSerializer(serializers.ModelSerializer):
   def validate(self, attrs):
        city = attrs['city']
        street = attrs['street']
        street_number = attrs['street_number']
        apartment_number = attrs['apartment_number'] if 'apartment_number' in attrs else None
        unique = check_address_unique(city, street, street_number, apartment_number)
        if not unique:
            raise serializers.ValidationError(_('Another user has already been registered under this address.'))
        return attrs

问题是传递错误的字段名称是以下标准non_field_errors：

{"non_field_errors":["Another user has already been registered under this address."]}

我想以某种方式为该错误指定一个自定义名称，因此所需的输出将是：

{"address":["Another user has already been registered under this address."]}

如何做到这一点？

Answer 1

对于单个ValidationError，您可以这样做：

raise serializers.ValidationError({
    'address': _('Another user has already been registered under this address.')
})

如果要全局覆盖此名称，则可以使用NON_FIELD_ERRORS_KEYREST框架设置。
