貓鼬 - 創建並將數據插入新集合

Question

現在我是MEAN.io中的初學者。我正在使用mongoose將數據插入數據庫。於是我跟着從here.

代碼在我app.js

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 
var ObjectId = Schema.ObjectId; 
var Factory = require('./module.factory.js'); 
mongoose.connect('mongodb://localhost/angular'); 
var db = mongoose.connection; 
var dbCollection = db.collections; 
var factory = new Factory(Schema,mongoose); 
factory.createSchemas(); 

在module.factory.js

var Factory = function(Schema,mongoose) { 
this.Schema = Schema; 
this.mongoose = mongoose; 
this.Item = null; 

this.createSchemas = function() { 

    var PersonSchema = new this.Schema({ 
     first_name: String, 
     last_name: String, 
     city: String, 
     state: String 
    }); 
    this.Person = mongoose.model('Person',PersonSchema); 
}; 

this.getPerson = function(query,res) { 
    this.Person.find(query,function(error,output) { 
     res.json(output); 
    }); 
}; 

this.doLogin = function(query,res) { 
    this.Person.findOne(query,function(error,output) { 
    console.log(query); 
     res.json(output); 
    console.log(output); 
    }); 
}; 
}; 
module.exports = Factory; 

插入數據：

app.post('/insert', function (req, res) { 
req.addListener('data', function(message) 
    { 
     var command = JSON.parse(message); 
     var document = {first_name: command.fname, 
      last_name: command.lname, 
      city: command.city, 
      state: command.state}; 
     dbCollection.user.insert(document,function(err, records){ 
     res.send('Inserted'); 
     }); 
    }); 
}); 

它拋出的TypeError: Cannot call method 'insert' of undefined

0123錯誤

但是，如果我把dbCollection.people.insert，它工作正常。任何人都可以告訴我如何創建新的集合並在其中插入數據。

我做了這些改變來解決這個問題：

而是在蒙戈外殼製作收藏，我把下面的代碼module.factory.js

this.Person = mongoose.model('Person',PersonSchema); 
this.Person.db.collection("user", { .... });
