给定这个集合:[{"users":[{"name":"one"},{"name":"two"}]},{"users":[{"name":"one"},{"name":"three"}]},{"users":[{"name":"fifteen"},{"name":"one"}]}]我如何使用值(即“one”和“two”)查询它,以便findOne方法仅返回具有两者"name":"one"和"name":"two"的文档(顺序不相关的)?users数组总是有2个元素,不多也不少。我正在尝试以下方法:Collection.findOne({"users":{$all:["one","two"

我将node.js与typescript@1.7.5、express@4.13.3、mongoose@4.3.7和mongodb@3.2.0一起使用编译错误:TS2345:Argumentoftype'(error:any,document:any)=>void'isnotassignabletoparameteroftype'(err:any)=>void'.行:(error,document)=>{即使出现此编译错误,运行时一切正常。我该如何解决这个错误?importexpress=require("express");importbodyParser=require('body-
这是我的第一次尝试,它非常简单,我只想找到所有具有提供参数(框:“框1”)的文档,并在其中找到具有提供的属性(用品:“清洁”)的所有文档).然后将所有这些文件从盒子:“盒子1”更新到盒子:“盒子2”。结果是所有清洁用品现在都移到了Box2。因此文档将从{box:"Box1",supplies:"Cleaning"}到{box:"Box2",supplies:"Cleaning"}错误"CannotPUT/updatebox/Box%201/Cleaning"//inPostman"404NotFound"//inPostmanlog架构和模型varboxSchema=newmongoo

使用Mongoose@4.2.6,我想连接到一个分片的MongoDB实例。consturl="mongodb://user:pass@localhost:27022,localhost:27023/db";//ThisneverresolvesMongoose.connect(url,(err,db)=>{...});当我使用nativeMongoDB@2.0.48库(与Mongoose使用的版本相同)建立连接时,它可以正常工作。consturl="mongodb://user:pass@localhost:27022,localhost:27023/db";//Thisresolve
我的Mongoose查询返回了这样一个JSON:[{"messages":[{"body":"thisisthebody","sender":"John","_id":"56ffbabb9a984f0804e8b3a0"},{"body":"messagebody","sender":"Jake","_id":"56ffc60c68a75ab835a7e097"}]}]我想得到这个(只有数组的内容,没有它的名字):[{"body":"thisisthebody","sender":"John","_id":"56ffbabb9a984f0804e8b3a0"},{"body":"mes
