在dailykey中添加条目时，有两种情况需要处理a)添加新的一天-:{"day":6,"sessions":300}b)更新特定日期的字段，例如重新计算session并将第2天更改为105示例架构{_id:"201010/site-1/apache_pb.gif",metadata:{date:ISODate("2000-10-00T00:00:00Z"),site:"site-1",page:"/apache_pb.gif"},daily:[{"day":1,"sessions":300,"bounces":10},{"day":2,"sessions":100,"bounces"
我在MongoDB中有一个文档集合，其结构如下(有多个容器文档，每个容器文档包含Sessions，每个session包含1个订单，每个订单包含多个项目):{"Sessions":[{"ID":"1882a092-d395-45d1-b36b-e2fa3df81b95","Order":{"Items":[{"_id":"a9c94a5e-10ef-433d-9c63-f4555eb7c2a7","Title":"UPDATETHIS",}]}}],"_id":"1b640bc4-fdb4-49b1-9c60-e4c6f1bd0405"}我想更新session中订单中给定Item的Tit
{"_id":ObjectId("57693a852956d5301b348a99"),"First_Name":"SriRam","Last_Name":"Bandi","Email":"chinni001sriram@gmail.com","Sessions":[{"Class":"facebook","ID":"1778142655749042","Login_Time":ISODate("2016-06-21T13:00:53.867Z"),"Logout_Time":ISODate("2016-06-21T13:01:04.640Z"),"Duration":null}],"
我尝试将用户httpsession存储在mongodb中。我找到了这个不错的gem:https://github.com/biilmann/mongo_sessions并尝试使用它。我得到undefinedmethod`master'forMongoid:Module比我改旧了:collection=>lambda{Mongoid.master.collection('sessions')}一些应该工作并带来session集合的东西:Mongoid::Sessions.default.collections.find{|i|i.name=='sessions'}但我得到:Moped::
假设我有一些MongoDB事件文档，每个文档都有许多在不同日期发生的session。我们可以将其表示为:db.events.insert([{_id:'5be9860fcb16d525543cafe1',name:'Past',host:'5be9860fcb16d525543daff1',sessions:[{date:newDate(Date.now()-1e8)},{date:newDate(Date.now()+1e8)}]},{_id:'5be9860fcb16d525543cafe2',name:'Future',host:'5be9860fcb16d525543daff2
{"_id":ObjectId("576155a6cd87b68f7e6e42c9"),"First_Name":"ok","Last_Name":"jaao","Email":"xyz@gmail.com","Sessions":[{"Last_Login":"Wed,Jun14,20166:48PM","Class":"fb","ID":"123"},{"Last_Login":"Wed,Jun15,20166:48PM","ID":"111","Class":"fb"}],"Count":2},{"_id":ObjectId("576155ccf6d8979e7e77df27")
我的mongodb是3.6，我的nodejs应用程序使用的是mongo客户端3.0。下面是使用mongoclientsession保证因果关系的源码:constsession=client.startSession();constcol=client.db('test').collection('test');col.insert({a:true},{w:0,j:false,session}).then(()=>{returncol.count({session});}).then(ret=>{console.log(ret);}).catch(err=>console.error(e
我有这个简单的更新api调用:这是我的文档:{"_id":ObjectId("577a5b9a89xxx32a1"),"oid":{"a":0,"b":0,"c":NumberLong("1260351143035")},"sessions":[{}]}然后我尝试将1个元素插入session数组:db.getCollection('CustomerInfo').update({"oid.c":1260351143035},{$push:{"sessions.$.asessionID":"test123"}})但是我得到这个错误:WriteResult({"nMatched":0,"nU
