根据ViewSet中的模型@property过滤元素列表-Django Rest Framework

Question

下面是一个数据结构，可以通过使用 Django Rest Framework 构建的端点进行访问：

template <typename T>
void func(int start_size, int idx)
{
    cout << start_size << " " << idx << endl;
}

template <typename T, typename T2, typename... Args> // Addition of T2, and change sizeof...
void func(int start_size, int idx)
{
    if ((idx + 1) == int(start_size - int(1 + sizeof...(Args)))) {
        cout << start_size << " " << idx << endl;
        return;
    }
    func<T2, Args...>(start_size, idx);
}

我的模型如下：

配置

"sites": [{
    "id": 1,
    "configs": [
        {
            "id": 1,
            "subconfigs": [
                {
                    "id": 1,
                    "name": "subconfig_1",
                    "macro_subconfigs": [1, 2]
                    "flag": true
                },
                {
                    "id": 2,
                    "name": "subconfig_2",
                    "macro_subconfigs": [1]
                    "flag": false
                },
                {
                    "id": 3,
                    "name": "subconfig_3",
                    "macro_subconfigs": [2]
                    "flag": false
                },
            ],
            "macro_subconfigs": [
                {
                    "id": 1,
                    "flag": true,
                    "subconfigs": [
                        {
                            "id": 1,
                            "name": "subconfig_1",
                            "macro_subconfigs": [1, 2]
                            "flag": true
                        },
                        {
                            "id": 2,
                            "name": "subconfig_2",
                            "macro_subconfigs": [1]
                            "flag": false
                        },
                    ],
                    "name": "macro_subconfig_1"
                },
                {
                    "id": 2,
                    "flag": false,
                    "subconfigs": [
                        {
                            "id": 1,
                            "name": "subconfig_1",
                            "macro_subconfigs": [1, 2]
                            "flag": true
                        },
                        {
                            "id": 3,
                            "name": "subconfig_3",
                            "macro_subconfigs": [2]
                            "flag": false
                        },
                    ],
                    "name": "macro_subconfig_2"
                },
            ]
        }
    ]
}]

SubConfig

class Config(TimeStampedModel):
    site = models.ForeignKey("site.Site", related_name="configs")
    @property
    def macro_subconfigs(self):
        try:
            return MacroSubConfig.objects.filter(subconfigs__config__pk=self.pk).distinct()
        except MacroSubConfig.DoesNotExist:
            return tuple()

MacroSubConfig

class SubConfig(TimeStampedModel):
    name = models.CharField(max_length=200)
    config = models.ForeignKey(
        "Config", related_name="subconfigs", on_delete=models.CASCADE
    )
    flag = models.BooleanField(default=True)

还有我的序列化器：

class MacroSubConfig(TimeStampedModel):
    name = models.CharField(max_length=100)
    subconfigs = models.ManyToManyField(SubConfig, related_name="macro_subconfigs")
    flag = models.BooleanField(default=True)

在我的class SiteConfigSerializer(serializers.HyperlinkedModelSerializer): configs = ConfigSerializer(many=True) class Meta: model = Site fields = ("name", "configs") class SubConfigSerializer(serializers.ModelSerializer): class Meta: model = SubConfig fields = ("name") class ConfigSerializer(serializers.ModelSerializer): subconfigs = SubConfigSerializer(many=True) macro_subconfigs = MacroSubConfigSerializer(many=True) class Meta: model = Config fields = ("name", "subconfigs", "macro_subconfigs") class MacroSubConfigSerializer(serializers.HyperlinkedModelSerializer): subconfigs = serializers.PrimaryKeyRelatedField( many=True, queryset=SubConfig.objects.all() ) class Meta: model = MacroSubConfig fields = ["subconfigs", "name"] 中，我想在具有SiteViewSet的macro_subconfigs列表中过滤macro_subconfigs。我已经设法对子配置列表中的flag: true做同样的事情。

预期结果如下：

subconfigs

如何从"sites": [{ "id": 1, "configs": [ { "id": 1, "subconfigs": [ { "id": 1, "name": "subconfig_1", "macro_subconfigs": [1, 2] "flag": true } ], "macro_subconfigs": [ { "id": 1, "flag": true, "subconfigs": [ { "id": 1, "name": "subconfig_1", "macro_subconfigs": [1, 2] "flag": true }, { "id": 2, "name": "subconfig_2", "macro_subconfigs": [1] "flag": false }, ], "name": "macro_subconfig_1" } ] } ] }] 的Config对象的列表中过滤元素？

如有需要，随时问我更多的精度。谢谢
