适当地在 mongoDb 中创建数据

Question

我是 node.js 的新手，正在尝试创建获取服务。涵盖了节点部分，但由于这是我第一次做后端，所以我想在建模数据方面获得一些建议。

我有一个非常简单的 JSON，我想在我的 MongoDB 中使用它。

{
  "names": [
    “xyz",
    “abc",
    “def",
    “wxy",
    “stu",
    “ghi"
  ],
  “xyz": {
    “name": “XYZ",
    “at": “xyzid",
    “bird": “xyzbird",
    "music": “xyzmusic",
    “tube": “xyztube",
    "featured”:true
  },
  “abc": {
    “name": “ABC",
    “at": “abcat",
    “bird": “abcbird",
    “music": “abcmusic",
    "tube": “abctube",
    "featured":false
  },
  “def": {
    “name": “DEF",
    “at": “DEFAT",
    “bird": “DEFbird",
    “music": “defmusic",
    "tube": “deftube",
    "featured":false
  },
  “wxy": {
    “name": “WXY",
    “at": “wxyat",
    “bird": “wxybird",
    “music": “wxymusic",
    "tube": “wxytube",
    "featured":false
  },
 “stu": {
    “name": “STU",
    “at": “stuat",
    “bird": “stubird",
    “music": “stumusic",
    "tube": “stutube",
    "featured":false
 },
“ghi": {
    “name": “GHI",
    “at": “ghiat",
    “bird": “ghibird",
    “music": “ghimusic",
    "tube": “ghitube",
    "featured":false
 }
}

到目前为止，通过在线阅读，我似乎应该创建 2 个不同的集合，一个是 'Names'，另一个是 'Details'。这是正确的吗？

是否有其他最佳方式将此数据存储在 MongoDb 中，并且无需进行过多处理即可轻松访问这些数据。我正在使用 Mongoose 与 mongodb.

当然有。但首先你应该决定你的名字数组中会有多少名字。如果名字很少，那么你可以这样做：

{
"names": [
{
    name: “xyz",
    details: {
        “name": “XYZ",
        “at": “xyzid",
        “bird": “xyzbird",
        "music": “xyzmusic",
        “tube": “xyztube",
        "featured”:true
    }
},
{
    name: “abc",
    details: {
        “name": “ABC",
        “at": “abcat",
        “bird": “abcbird",
        “music": “abcmusic",
        "tube": “abctube",
        "featured":false
    }
},
{
    name: “def",
    details: {
        “name": “DEF",
        “at": “DEFAT",
        “bird": “DEFbird",
        “music": “defmusic",
        "tube": “deftube",
        "featured":false
    }
},
{
    name: “wxy",
    details: {
        “name": “WXY",
        “at": “wxyat",
        “bird": “wxybird",
        “music": “wxymusic",
        "tube": “wxytube",
        "featured":false
    }
},
{
    name: “stu",
    details: {
        “name": “STU",
        “at": “stuat",
        “bird": “stubird",
        “music": “stumusic",
        "tube": “stutube",
        "featured":false
    }
},
{
    name: “ghi",
    details: {
        “name": “GHI",
        “at": “ghiat",
        “bird": “ghibird",
        “music": “ghimusic",
        "tube": “ghitube",
        "featured":false
    }
}
]}

但是如果名称数组中有数百万个名称，那么我建议您为每个文档创建一个 names 集合，例如：

{
    “name": “GHI",
    “at": “ghiat",
    “bird": “ghibird",
    “music": “ghimusic",
    "tube": “ghitube",
    "featured":false
}

我也认为在这种情况下不需要名称字段。
