Mongoose的model.find()查出来的为啥不是文档呢；求帮助！
发布于 6个月前 作者 jaycreater 652 次浏览

查询出来是一堆没用的东西呢，为啥不是文档呢：

//db.js var mongoose = require(‘mongoose’); mongoose.connect(‘mongodb://localhost/mybooks’); module.exports = mongoose;

//find.js var mongoose = require(‘./db’); var Schema = mongoose.Schema; var booksSchema = new Schema({ name: String, author: String });

var bookModel = mongoose.model('ctbook’, booksSchema); console.log(bookModel.find());

{ _mongooseOptions: {}, mongooseCollection: { collection: null, opts: { bufferCommands: true, capped: false }, name: 'ctbooks’, conn: { base: [Object], collections: [Object], models: {}, replica: false, hosts: null, host: 'localhost’, port: 27017, user: undefined, pass: undefined, name: 'mybooks’, options: [Object], otherDbs: [], _readyState: 2, _closeCalled: false, _hasOpened: false, _listening: false, _events: {}, db: [Object] }, queue: [], buffer: true }, model: { [Function: model] base: { connections: [Object], plugins: [], models: [Object], modelSchemas: [Object], options: [Object] }, modelName: 'ctbook’, model: [Function: model], db: { base: [Object], collections: [Object], models: {}, replica: false, hosts: null, host: 'localhost’, port: 27017, user: undefined, pass: undefined, name: 'mybooks’, options: [Object], otherDbs: [], _readyState: 2, _closeCalled: false, _hasOpened: false, _listening: false, _events: {}, db: [Object] }, discriminators: undefined, schema: { paths: [Object], subpaths: {}, virtuals: [Object], nested: {}, inherits: {}, callQueue: [], _indexes: [], methods: {}, statics: {}, tree: [Object], _requiredpaths: undefined, discriminatorMapping: undefined, _indexedpaths: undefined, options: [Object], _events: {} }, options: undefined, collection: { collection: null, opts: [Object], name: 'ctbooks’, conn: [Object], queue: [], buffer: true } }, op: 'find’, options: {}, _conditions: {}, _fields: undefined, _update: undefined, _path: undefined, _distinct: undefined, _collection: { collection: { collection: null, opts: [Object], name: 'ctbooks’, conn: [Object], queue: [], buffer: true } }, _castError: null }

直接在用mongo能查到吗？ 如果可以的话。那就是你mongoose用的有问题。 我是这样用的 

var meetingSchema = new Schema({
id:Schema.Types.ObjectId,
meetingRoomName: String,
meetingId:String,
meetingSubject:String,
members: Schema.Types.Mixed,
updated: { type: Date, default: Date.now },
startTime:{ type: Date, default: Date.now },
ownerCorpId:String,
ownerName:String
});
var meetingModel = mongoose.model('meetings’, meetingSchema);
var query2 = meetingModel.find(conditions);
query1.exec(）；

你这貌似打出来的是mongoose吧。

@xuwenfei886 少点东西：

var mongoose = require(‘./db’),
_ = require(“underscore”),
Schema = mongoose.Schema;

db.js：

var mongoose = require(‘mongoose’).connect(‘mongodb://localhost/Titan’);
module.exports = mongoose;

Model.find()查出来的就是文档 ，应该是哪里写错了吧 ， 上代码瞧瞧

find查询出来的是mongoose的doc对象，支持update等操作，不是POJO，用doc.toObject()转换成POJO

@kenticny 麻烦您看下，代码贴上来了。

@xuwenfei886 我把代码贴上来啦，麻烦您给看一下吧。

@showen 不知道呢，我直接用mongo给查询出来。

@jaycreater -.-mongoose执行find是异步的…返回值是mongoose本身对象 也可以说在nodejs中大多数都是方法都是异步执行的

bookModel.find(function(err, docs) {
    // err是错误信息，docs就是查询返回的文档，是一个数组
    console.log(docs);
});

bookModel.find({},[],{},function(err,docs){ console.log(docs); })

@kenticny 但是，我要怎么把docs给视图使用呢。

@jiangli373 这样控制台是可以打印出来，可是怎么给视图使用呢？因为，我主要是查出来给视图模板使用的。

@jaycreater 以express中为例

bookModel.find(function(err, docs) {
    if(err) {
        console.error(err);
        return;
    }
    res.render('view', {
        list: docs
    });
});

@kenticny 嗯嗯，谢谢啦。

@jaycreater 楼上有人给出答案了
