MongoDB聚合-在一个数组中显示来自不同数组的值

我有这类数据

{ 
"_id" : 6444, 
"name" : [
    {
        "name" : "John", 
        "sourcesID" : [
            1, 
            2
        ]
    }, 
    {
        "name" : "Jack", 
        "sourcesID" : [
            3, 
            4 
        ]
    }       
    ],
"address" : [
    {
        "city" : "Chicago", 
        "sourcesID" : [
            3, 
            4 
        ]
    }, 
    {
        "city" : "Boston", 
        "sourcesID" : [
            5, 
            6
        ]
    }       
]       

}

我希望聚合数据，以便能够匹配某个sourcesID，并找到来自此源的所有信息类型

这就是我希望实现的目标

{"type" : "name", "sourceID" : 1}
{"type" : "name", "sourceID" : 2}
{"type" : "name", "sourceID" : 3}
{"type" : "name", "sourceID" : 4}
{"type" : "address", "sourceID" : 3}
{"type" : "address", "sourceID" : 4}
{"type" : "address", "sourceID" : 5}
{"type" : "address", "sourceID" : 6}

感谢您的帮助。

假设始终存在

sourceID

字段，您可以运行转换，以便能够动态读取对象键，然后运行三次以获取每个

sourceID

的单个文档：

db.collection.aggregate([
    {
        $project: {
            data: {
                $filter: {
                    input: { $objectToArray: "$$ROOT" },
                    cond: {
                        $ne: [ "$$this.k", "_id" ]
                    }
                }
            }
        }
    },
    { $unwind: "$data" },
    { $unwind: "$data.v" },
    { $unwind: "$data.v.sourcesID" },
    {
        $project: {
            _id: 0,
            type: "$data.k",
            sourceID: "$data.v.sourcesID"
        }
    }
])

它总是

sourcesID

还是有时

sources

有时

sourcesID

或者完全不可预测？很好！在我的例子中这是一个错误。都应该是sourcesID。我现在就修。
