我想为我在Mongoid中的分组提供一个条件，但是如何为条件哈希中的一个属性发送多个值？这就是我想做的:PageViews.collection.group(cond:{page_id:['4e6912618083ab383e000010','4e6912618083ab383e000009']},key:'timestamp',initial:{count:0},reduce:"function(x,y){y.count+=x.count;}")因此，任何带有page_id的PageView都将是查询的一部分，但我似乎无法获得条件哈希(cond)工作!我在这里做错了什么，我真的很困惑
这是我的文档架构:{"_id":ObjectId("5203c8b91afdd7160c6ecfd3"),"answer_calls":"","start":"10:00","end":"10:30","VDN_name":"SP_SYNDICATED_7","total_calls":"1","date":"01/07/2013","abandoned_calls":"","voicemail_calls":""}我尝试通过聚合框架:>dir.aggregate([{$group:{_id:{fecha:"$date",hora:"$start"},llamadas:{$sum:"$
在下面的查询中{$group:{_id:{success:'$success',responseCode:'$responseCode',label:'$label'},max_timeStamp:{$timeStamp:1},count_responseCode:{$sum:1},avg_value:{$sum:"$value"},count_success:{$sum:1}}}_id:{success:'$success',responseCode:'$responseCode',label:'$label'},如何翻译成在javamongodb驱动中使用。我试过了BasicDBL
我有以下文档结构{"app_id":"DHJFK67JDSJjdasj909","date":ISODate("2014-08-07T00:00:00.000Z"),"event_count":100,"events":[{"type":0,"value":12},{"type":10,"value":24},{"type":20,"value":36},{"type":30,"value":43}],"unique_events":[{"type":0,"value":5},{"type":10,"value":8},{"type":20,"value":12},{"type":30
我有两个系列。其中一个我希望添加对另一个的引用并在返回时填充它。这是我试图实现的示例json:{"title":"SomeTitle","uid":"some-title","created_at":"1412159926","updated_at":"1412159926","id":"1","metadata":{"date":"2016-10-17","description":"adescription"},"tags":[{"name":"Tag1","uid":"tag-1"},{"name":"Tag2","uid":"tag-2"},{"name":"Tag3","ui
(1)我已将以下内容添加到集合中:{"_id":1,"hitsPerOneSecond":[2,3,5,4,1,2,3,4,1,2],"startTime":ISODate("2012-04-07T10:41:33.380Z"),"returnCodeHits":{"300":5,"200":12},"xxxServer":"xxx:8100","statsSummarizedToSeconds":10,"pathStats_xxx_api_get_version":[0.2280779683225852,0.030849283020361273,0.9947690473370484]
我已经开始使用MEANStack创建Nodejs应用程序，因此我按照以下URL中的步骤使用MEAN初始化Nodejs应用程序。Link当我在终端中提供GRUNT或启动Nodejs应用程序时，我收到以下错误。events.js:72thrower;//Unhandled'error'event^Error:ENOENT,open'/home/vigneshmoha/Documents/node/branding/public/system/lib/bootstrap/dist/css/bootstrap.css'[nodemon]appcrashed-waitingforfilechan
这是我的查询，db.product.aggregate([{$match:{categoryID:4}},{"$group":{"_id":{"productID":"$productID","articleID":"$articleID","colour":"$colour","set&size":{"sku":"$skuID","size":"$size"},},}},{"$group":{"_id":{"productID":"$_id.productID","colour":"$_id.colour"},"size":{"$addToSet":{"sku":"$_id.set&
我使用mongodb2.6。我以这种形式存储了我的数据:{"_id":"my-sensor-1","points":[{"timeStamp":NumberLong("1453468362174"),"value":41},{"timeStamp":NumberLong("1453468483297"),"value":66},{"timeStamp":NumberLong("1453468485568"),"value":49},...]}为了聚合文档，我进行如下查询:db.pointsTest.aggregate([{$match:{$and:[{"points.timeStamp
我正在使用一个脚本来删除mongo上的重复项，它在一个包含10个项目的集合中工作，我将其用作测试，但是当我用于包含600万个文档的真实集合时，我得到了一个错误。这是我在Robomongo中运行的脚本(现在称为Robo3T):varbulk=db.getCollection('RAW_COLLECTION').initializeOrderedBulkOp();varcount=0;db.getCollection('RAW_COLLECTION').aggregate([//Grouponuniquevaluestoring_idvaluestoarrayandcount{"$grou
