node.js - Strapi 关系不返回正确的层次结构

Question

我正在尝试创建以下关系模型：

Section has many categories
Categories has many sub-categories

所以基本上我们在这里有三个集合：

1. 部分
2. 类别
3. 子类别

首先，我定义了Section和之间的关系Category：

然后，我创建了Categoryand之间的关系SubCategory：

我也填充了这些集合，当我打电话时，http://localhost:3002/sections我得到：

        "subcategories": [

                "category": 1,
                "description": null
            },
            {
                "id": 2,
                "name": "Estate 21",
                "published_at": "2020-12-03T11:54:42.000Z",
                "created_at": "2020-12-03T11:54:36.000Z",
                "updated_at": "2020-12-03T15:14:04.000Z",
                "category": 1,
                "description": null
            }
        ]
    }
]

从响应中可以看出，Section和之间的关系工作正常，但和Category之间的关系不正常。事实上，我已经定义了这些模型之间的 1:n 关系，但我得到：CategorySubCategory

{
    "id": 4,
    "name": "creativity",
    "published_at": "2020-11-20T10:21:36.000Z",
    "created_at": "2020-11-20T11:21:34.000Z",
    "updated_at": "2020-12-04T10:53:32.000Z",
    "description": null,
    "featured_image": null,
    "categories": [
        {
            "id": 1,
            "name": "Archivio",
            "published_at": "2020-11-20T10:57:34.000Z",
            "created_at": "2020-11-20T11:22:48.000Z",
            "updated_at": "2020-12-04T10:50:50.000Z",
            "subcategory": null,
            "feature_image": null
        },

另一个奇怪的事情是，在仪表板中，我实际上可以将子类别与 selected 相关联Category，请参阅：

所以我应该有回应：

{
    "id": 4,
    "name": "creativity",
    "published_at": "2020-11-20T10:21:36.000Z",
    "created_at": "2020-11-20T11:21:34.000Z",
    "updated_at": "2020-12-04T10:53:32.000Z",
    "description": null,
    "featured_image": null,
    "categories": [
        {
            "id": 1,
            "name": "Archivio",
            "published_at": "2020-11-20T10:57:34.000Z",
            "created_at": "2020-11-20T11:22:48.000Z",
            "updated_at": "2020-12-04T10:50:50.000Z",
            "subcategories": [
                ...
            ],
            "feature_image": null
        },

我做错了什么还是 Strapi 的关系引擎有问题？
