Arrays MongoDB阵列副本,arrays,mongodb,count,duplicates,Arrays,Mongodb,Count,Duplicates,我有下面的查询，它使用lookup创建一个新数组，以便“连接”两个集合，一旦合并了数据，y按“group”数据分组，并显示events字段，正如您可以看到的，它有重复项，例如“times this issues events”（此问题发生的次数），这就是它的意思。我想展示一些东西，比如： Group1 { Event 1 : 120 Times Event 2 : 2478 Times Event 3 : 120 Times } Group2 { Event 1 : 455 Times Eve

我有下面的查询，它使用lookup创建一个新数组，以便“连接”两个集合，一旦合并了数据，y按“group”数据分组，并显示events字段，正如您可以看到的，它有重复项，例如“times this issues events”（此问题发生的次数），这就是它的意思。我想展示一些东西，比如：

Group1
{
Event 1 : 120 Times
Event 2 : 2478 Times
Event 3 : 120 Times
}

Group2
{
Event 1 : 455 Times
Event 2 : 24  Times
Event 3 : 146 Times
}
我的代码

 db.events.aggregate([

   { $match : { netcode : "N000362" } },

    {
      $lookup:
        {
          from: "nodes",
          localField: "name",
          foreignField: "name",
          as: "event_joined"


        }

   },


  { $unwind:  {path: "$event_joined"}},


  { $project : { name : 1, event : 1, "event_joined.group": 1 ,_id:0} },

  { $unwind:  {path: "$event_joined"}},

  { $group : { _id : "$event_joined.group", eventos: { $push: "$event"} } },


])
输出：

我在MongoDB文档中进行了搜索和尝试，但我认为它缺少很多示例和语法

使用
{$addToSet:$event}
而不是
{$push:$event}
。看起来你的
$project+$unwind
阶段是多余的。再次感谢你，我会很快尝试，请不要离开：DinDect它是多余的，我只是在测试，有没有办法看看每一个我有多少？我不想删除重复的，但是，我想看看每一个我有多少抱歉误解了你的帖子。请尝试
{$group:{\u id:{group:$event\u joined.group]，event:$event}，count:{$sum:1}}
