我正在嘗試運(yùn)行一個(gè)$graphLookup類似下面所示的示例：目的是在給定特定記錄（$match在此處有注釋）的情況下，通過immediateAncestors屬性檢索其完整的“路徑” 。如您所見，這沒有發(fā)生。我$convert在這里介紹了_idfrom的處理方式，因?yàn)閟tring相信可以與_idfrom immediateAncestors記錄列表（是string）進(jìn)行“匹配” 。因此，我確實(shí)使用不同的數(shù)據(jù)運(yùn)行了另一個(gè)測試（不ObjectId涉及）：db.nodos.insert({"id":5,"name":"cinco","children":[{"id":4}]})db.nodos.insert({"id":4,"name":"quatro","ancestors":[{"id":5}],"children":[{"id":3}]})db.nodos.insert({"id":6,"name":"seis","children":[{"id":3}]})db.nodos.insert({"id":1,"name":"um","children":[{"id":2}]})db.nodos.insert({"id":2,"name":"dois","ancestors":[{"id":1}],"children":[{"id":3}]})db.nodos.insert({"id":3,"name":"três","ancestors":[{"id":2},{"id":4},{"id":6}]})db.nodos.insert({"id":7,"name":"sete","children":[{"id":5}]})和查詢：db.nodos.aggregate( [  { $match: { "id": 3 } },  { $graphLookup: {      from: "nodos",      startWith: "$ancestors.id",      connectFromField: "ancestors.id",      connectToField: "id",      as: "ANCESTORS_FROM_BEGINNING"    }  },  { $project: {      "name": 1,      "id": 1,      "ANCESTORS_FROM_BEGINNING": "$ANCESTORS_FROM_BEGINNING.id"    }  }] )...輸出了我期望的結(jié)果（這5條記錄直接或間接與id3 條記錄相關(guān)）：{    "_id" : ObjectId("5afe270fb4719112b613f1b4"),    "id" : 3.0,    "name" : "três",    "ANCESTORS_FROM_BEGINNING" : [         1.0,         4.0,         6.0,         5.0,         2.0    ]}問題是：有沒有一種方法可以實(shí)現(xiàn)我一開始提到的對(duì)象？我正在運(yùn)行Mongo 3.7.9（來自官方Docker）提前致謝！
