以下のJsonのためにmongodbスキーマを作成するには？

Question

{ 
    "_id" : ObjectId("5a0e77f4b7368f14c088f542"), 
    "folderName" : "team 4", 
    "tag" : "search", 
    "ismainFolder" : true, 
    "innerFolder" : [ 
        { 
         parentfolderId" : null, 
         "ismainFolder" : false, 
         "foldername" : "Onkar 11" 
         "subinnerFolder" : [ 
             { 
              "parentfolderId" : null, 
              "ismainFolder" : false, 
              "foldername" : "Onkar 11" 
              "thirdSubFolder" : [ 
                 { 
                  "parentfolderId" : null, 
                  "ismainFolder" : false, 
                  "foldername" : "Onkar 11" 
                 }, 
                 { 
                  "parentfolderId" : null, 
                  "ismainFolder" : false, 
                  "foldername" : "Onkar 11" 
                 } 
                ] 
             }, 

            ] 
        }, 
       ] 
} 

innerFolder、subinnerFolderなど（内部フォルダ構造がネストされるように）以下のjson形式のmongodbスキーマを作成する必要があります。

Answer 1

を見てみましょう。
ここでの唯一の問題は、ヌル値です。
可能性の1つは、テキストとして保存することです。 null値を格納しないことを検討してください。

const detailFolder = { 
    parentfolderId: { type: String, default: null }, 
    ismainFolder: Boolean, 
    foldername: String 
} 

const schema = { 
    folderName: String, 
    tag: String, 
    ismainFolder: Boolean, 
    innerFolder: [{ 
    detailFolder, 
    subinnerFolder: [{ 
     detailFolder, 
     thirdSubFolder: [ detailFolder ] 
    }] 
    }] 
} 

Answer 2

以下はhttps://jsonschema.net/#/によって生成されたjsonスキーマです。必要に応じて編集することができます。マングースのスキーマの場合は、ここでマングーススタイルでスキーマの例があるhttps://github.com/topliceanu/mongoose-gen
