通过MongoDB中的骨料结构数据

Question

我一直在通过MongoDB中的汇总FREMWORK创建收集的统计信息，我想创建一个包含用户ID的对象，而Arry包含用户拥有的呼叫指示（出站，入站等）方向和在Spesific方向上拨打的总呼叫。

例如：

我有此文档：

{
    "userId" : "628pp9d91ce06ba3ed6cb0pf6",
    "date" : "1655983001341",
    "direction" : "outbound",
    "duration" : 35.0,
    "network" : null,
    "status" : "completed",
    "from" : "src-1",
    "company" : "companyName",
}

我试图通过类似的同意制作统计文档：

db.test.aggregate([
    {$match : { company : "companyName"}},
    {$group : { _id : "$userId", data : { $addToSet : { direction : "$direction", duration : { $sum : "$duration"}, amount :  { $sum : 1} } } } }
])

预期值必须为：

{
    "_id" : "---",
    "data" : [ 
        {
            "direction" : "unanswered",
            "duration" : 26.0,
            "amount" : 3.0
        }, 
        {
            "direction" : "outbound",
            "duration" : 863.0,
            "amount" : 3.0
        }
    ]
}

但是我得到的输出是：

{
    "_id" : "6268f634106db6972be89241",
    "data" : [ 
        {
            "direction" : "unanswered",
            "duration" : 12.0,
            "amount" : 1.0
        }, 
        {
            "direction" : "outbound",
            "duration" : 767.0,
            "amount" : 1.0
        }, 
        {
            "direction" : "outbound",
            "duration" : 41.0,
            "amount" : 1.0
        }, 
        {
            "direction" : "outbound",
            "duration" : 55.0,
            "amount" : 1.0
        }, 
        {
            "direction" : "unanswered",
            "duration" : 1.0,
            "amount" : 1.0
        }, 
        {
            "direction" : "unanswered",
            "duration" : 13.0,
            "amount" : 1.0
        }
    ]
}

我做错了什么？
