Question

这里我已经为图表中的节目计数日期创建了一个查询。我用过mongodb。我有一个表集合，并在表集合中存储多个文档，在文档中一个归档是Action。我想显示计数日期明智行动像评论，像动作计数想要show.but我创建一个查询使用group by但我返回查询中的所有文档没有在查询中获得日期明智的过滤数据。我不知道在查询中我的错误在哪里，任何人都知道，请告诉我。我想要从开始到结束日期之间的日期。

这是我的文件=＆gt;

我当前的o / p =＆gt;

  { _id: '1507020728000', CommentCount: 1 ,Likecount:0},
  { _id: '1507099928000', CommentCount: 1 ,Likecount:0},
  { _id: '1507099928000', CommentCount: 1 ,Likecount:0},
  { _id: '1507186328000', CommentCount: 1,Likecount:0 },
  { _id: '1507186328000', CommentCount: 1,Likecount:0 },
  { _id: '1507279928000', CommentCount: 1,Liekcount:1},
  { _id: '1507279928000', CommentCount: 1,Liekcount:1},
  { _id: '1504256404000', CommentCount: 0,Liekcount:1},

我的例外情况o / p =＆gt;

  { _id: '1507020728000', CommentCount: 1 ,Likecount:0},
  { _id: '1507099928000', CommentCount: 2 ,Likecount:0},
  { _id: '1507186328000', CommentCount: 2,Likecount:0 },
  { _id: '1507279928000', CommentCount: 2,Liekcount:1},

这是我的查询=＆gt;

            ActivityHistory.aggregate([
          {
              "$match": {
                  "InId": ObjectId("595e3b2033961713940442cd"),                     
                  "datetime": {
                      "$lte": parseInt("1507280404000"), "$gte": parseInt("1507021204000")
                  },
                  "Action": {                          
                      $in: ["Comment", "Like"]
                  }
              }
          },      
          {              
              "$group": {
                  "_id": "$datetime",                               
                  "CommentCount": { $sum: { $cond: [{ $eq: ["$Action", "Comment"] }, 1, 0] } },
                  "Likecount": { $sum: { $cond: [{ $eq: ["$Action", "Like"] }, 1, 0] } },                
              },
                  },
                   { '$sort': { '_id': 1 } }
            ]).exec(function (err, data) {
                if (err) {
                    console.log(err);            
                }
                else {            
                    console.log("Final=>",data);            
                }
        });

使用mongodb通过日期获取错误数据使用Group？
