Question

我的收藏将如下所示，

{
"_id" : ObjectId("591c5971240033283736860a"),
"status" : "Done",
"createdDate" : ISODate("2017-05-17T14:09:20.653Z")
"communications" : [ 
    {
        "communicationUUID" : "df07948e-4a14-468e-beb1-db55ff72b215",
        "communicationType" : "CALL",
        "recipientId" : 12345,
        "createdDate" : ISODate("2017-05-18T14:09:20.653Z")
        "callResponse" : {
            "Status" : "completed",
            "id" : "dsd45554545ds92a9bd2c12e0e6436d",
        }
    }
]}
{
"_id" : ObjectId("45sdsd59124003345121450a"),
"status" : "ToDo",
"createdDate" : ISODate("2017-05-17T14:09:20.653Z")
"communications" : [ 
    {
        "communicationUUID" : "45sds55-4a14-468e-beb1-db55ff72b215",
        "communicationType" : "CALL",
        "recipientId" : 1234,
        "createdDate" : ISODate("2017-05-18T14:09:20.653Z")
        "callResponse" : {
            "Status" : "completed",
            "id" : "84fe862f1924455dsds5556436d",
        }
    }
]}

目前我正在编写两个聚合查询来实现我的要求，我的查询将在
下面

db.collection.aggregate(
{ $project: {
      dayMonthYear: { $dateToString: { format: "%d/%m/%Y", date: "$createdDate" } },
      status: 1,
}},
{ $group: { 
    _id: "$dayMonthYear",
    Pending: { $sum: { $cond :  [{ $eq : ["$status", "ToDo"]}, 1, 0]} },
    InProgress: { $sum: { $cond :  [{ $eq : ["$status", "InProgress"]}, 1, 0]} },
    Done: { $sum: { $cond : [{ $eq : ["$status", "Done"]}, 1, 0]} },
    Total: { $sum: 1 }
}}

我的输出将是，

{"_id" : "17/05/2017", "Pending" : 1.0, "InProgress" : 0.0, "Done" : 1.0, "Total" : 2.0 }

使用上面的查询我可以计算，但我需要根据通信状态找到计数，所以我写了另外一个查询来实现，

db.collection.aggregate(
{"$unwind":"$communications"},
{ $project: {
    dayMonthYear: { $dateToString: { format: "%d/%m/%Y", date: "$createdDate" } },
    communications: 1
}},
{ "$group": { 
    _id: "$dayMonthYear",
    "total_call": { $sum: { $cond :  [{ $or : [ { $eq: [ "$communications.callResponse.Status", "failed"] },
                                                { $eq: [ "$communications.callResponse.Status", "busy"] },
                                                { $eq: [ "$communications.callResponse.Status", "completed"] },
                                                { $eq: [ "$communications.callResponse.Status", "no-answer"] }
                                      ]}, 1, 0 ] }},
    "engaged": { $addToSet: { $cond :  [{ $eq : ["$communications.callResponse.Status", "completed"]}, 
                                                "$communications.recipientId", "null" ]} },
    "not_engaged": { $addToSet: { $cond: [{ $or : [ { $eq: [ "$communications.callResponse.Status", "failed"] },
                                                             { $eq: [ "$communications.callResponse.Status", "busy"] },
                                                             { $eq: [ "$communications.callResponse.Status", "no-answer"] } ]}, 
                                                "$communications.recipientId", "null" ] }}
}},
{ "$project": {
    "_id": 1,
    "total_call": 1,
    "engaged": { "$setDifference": [ "$ngaged", ["null"] ] },
    "not_engaged": { "$setDifference": [ "$not_engaged", ["null"] ] },
}},
{ "$project": {
    "total_call": 1,
    "engaged": { "$size": "$engaged" },
    "not_engaged": { "$size": { "$setDifference": [ "$not_engaged", "$engaged" ] }},
}})

我的输出将是，

{"_id" : "18/05/2017", "total_call" : 2.0, "engaged" : 2, "not_engaged" : 0}

使用上面的查询我可以计算，但我想在单个查询中实现它

我正在寻找类似

的输出

{"_id":"17/05/2017", "Pending" : 1.0, "InProgress" : 0.0, "Done" : 1.0, "total_call" : 0, "engaged" : 0, "not_engaged" : 0}
{"_id":"18/05/2017", "Pending" : 0.0, "InProgress" : 0.0, "Done" : 0.0, "total_call" : 2, "engaged" : 2, "not_engaged" : 0}

任何人都可以建议或提供我获得上述结果的好方法。
