所以我正在阅读Manning的GettingMean书，并按照第5章中的步骤进行操作，我正在尝试使用Mongolab上的数据库作为Heroku的附加组件。当我运行这段代码(在本地和Heroku上)它返回这个错误:MongoError:getaddrinfoENOTFOUNDundefinedundefined:27017这是我当前的代码:varmongoose=require('mongoose');vardbURI="mongodb://localhost/loc8r";if(process.env.NODE_ENV==='production'){dbURI=process.env
我有Node.js服务，我在其中使用mongo-API与Document/CosmosDB进行通信。我的服务运行良好并执行了所有的crud操作，但1分钟后从服务中抛出了一些mongo错误。/document-db-service/node_modules/mongodb/lib/utils.js:123process.nextTick(function(){throwerr;});^MongoError:pooldestroyedatPool.write(/document-db-service/node_modules/mongodb-core/lib/connection/pool

我最近将Play升级到2.3.5版并尝试将其与ReactiveMongo一起使用。但是，每次我尝试从mongoDB读取数据时都会发生异常。这是我的build.sbt:name:="""ReactiveMongoRestExample"""version:="1.0-SNAPSHOT"lazyvalroot=(projectinfile(".")).enablePlugins(PlayScala)scalaVersion:="2.11.1"libraryDependencies++=Seq(jdbc,anorm,cache,ws,"org.reactivemongo"%%"play2-r

我有一个简单的node.js代码，它试图获取对象、填充字段然后更新同一个对象:varMongoClient=require('mongodb').MongoClient,Db=require('mongodb').Db,Server=require('mongodb').Server,ObjectID=require('mongodb').ObjectID;vardb=newDb('testing',newServer('localhost',27017));db.open(function(err,db){varUsers=db.collection('users');Users.f

我想更新一个数组并返回文档。我的findAndModify语法是否正确？this.becomeFollower=function(title,username,callback){"usestrict"posts.findAndModify({query:{"title":title,"roster":"yes"},update:{"$addToSet":{"followers":username}},new:true,upsert:true},function(err,doc){console.log('findandmodified'+doc);});}我用这个没问题:posts.
