如何使用 node.js 将 json 数组插入 mongodb？

Question

当我尝试将我的 json 数组保存到 mongodb 时遇到问题，我没有显示任何想法， app.js

var express = require('express');
var path = require('path');
var mongoose = require('mongoose');

var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var NodeGeocoder = require('node-geocoder');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));


var promise = mongoose.connect('mongodb://localhost/sirketler')

var Company = require('./app/models/company');

app.get('/', function (req, res) {
    var newCompany = Company({
      json:"sirketler" [
            {"Cityname":"Adana",
	     "OSBname":"4 K PLASTİK AMB.TURZ.TAŞ.PET.ÜRÜN.DAY.TÜK.MAL.TEKS.GIDA VE TAR.ÜRÜN.İNŞ.İTH.İHR.SAN.TİC.LTD.ŞTİ.", 
	     "Address":"A.H.S. ORGANİZE SANAYİ BÖLGESİ OSB LOKMAN HEKİM CADDESİ NO:2 ", 
	     "Phone":123123123,
	     "Fax":234234234,
	     "Sector":"KAUÇUK VE PLASTİK ÜRÜNLERİN İMALATI ", 		
	     "Email":"gokhan@4kplastik.com", "Website":"www.4kplastik.com"},
	    {"Cityname":"Ankara", "OSBname":"ABDİOĞULLARI PLASTİK VE AMB.SAN. A.Ş.",
	    "OSBname":"ABDİOĞULLARI PLASTİK VE AMB.SAN. A.Ş.",
	    "Address":"A.H.S. ORGANİZE SANAYİ BÖLGESİ OSB SABANCI CADDESİ NO: 8 ",
	    "Phone":432143123,
	    "Fax":243243243,
	    "Sector":"KAUÇUK VE PLASTİK ÜRÜNLERİN İMALATI ",
	    "Email":"info@abco.com.tr",
	    "Website":"www.abco.com.tr"}

]});


    // save the user
    newCompany.save(function(err) {
      if (err) throw err;

      console.log('User created!');
    });
})
app.listen (3000, function () {
  console.log('Example app listening on port 3000!')
})

company.js 来自 /home/furkan/companies/app/models/company.js

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

// create a schema
var companySchema = new Schema({

  Cityname: String,
  OSBname: { type: String},
  Address:{ type: String},
  Phone:{ type:Number},
  Fax:{ type:Number},
  Sector: { type: String},
  Email: {type: String},
  Website: { type: String},
  location: Number,
  meta: {
    age: Number,
    website: String
  },
  created_at: Date,
  updated_at: Date
});

// the schema is useless so far
// we need to create a model using it
var Company = mongoose.model('furkan', companySchema);

// make this available to our companys in our Node applications
module.exports = Company;

我看 对不起我的提问风格，我不知道如何问清楚，但我的问题是这样的，请帮助我解决这个问题。 我尝试在此处添加我的代码，但 cod 看起来不太好。

*如何更改我的架构？

Answer 1

您的架构没有json 字段，也没有sirketler。

当您使用架构时，您必须遵循其结构。

你想要类似的东西

app.get('/', function (req, res) {
    var newCompany = Company({
        Cityname: "Adana", 
        OSBname: "4 K PLASTİK AMB.TURZ.TAŞ.PET.ÜRÜN.DAY.TÜK.MAL.TEKS.GIDA VE TAR.ÜRÜN.İNŞ.İTH.İHR.SAN.TİC.LTD.ŞTİ.", 
        Address: "A.H.S. ORGANİZE SANAYİ BÖLGESİ OSB LOKMAN HEKİM CADDESİ NO:2 ", 
        Phone: 123123123,
        Fax: 234234234,
        Sector: "KAUÇUK VE PLASTİK ÜRÜNLERİN İMALATI ", 
        Email: "gokhan@4kplastik.com", 
        Website: "www.4kplastik.com"
    });

    // save the user
    newCompany.save(function(err) {
        if (err) throw err;
        console.log('User created!');
    });
})

编辑

只需使用Model.create。但同样，每个公司都必须遵循架构中指定的结构。

Company.create([
    // company 1
    {
        Cityname: "Adana",
        OSBname: "4 K PLASTİK AMB.TURZ.TAŞ.PET.ÜRÜN.DAY.TÜK.MAL.TEKS.GIDA VE TAR.ÜRÜN.İNŞ.İTH.İHR.SAN.TİC.LTD.ŞTİ.", 
        Address: "A.H.S. ORGANİZE SANAYİ BÖLGESİ OSB LOKMAN HEKİM CADDESİ NO:2 ", 
        Phone: 123123123,
        Fax: 234234234,
        Sector: "KAUÇUK VE PLASTİK ÜRÜNLERİN İMALATI ",
        Email: "gokhan@4kplastik.com", 
        Website: "www.4kplastik.com"
    },
    // company 2
    {
        Cityname: "Ankara", 
        OSBname: "ABDİOĞULLARI PLASTİK VE AMB.SAN. A.Ş.",
        OSBname: "ABDİOĞULLARI PLASTİK VE AMB.SAN. A.Ş.",
        Address: "A.H.S. ORGANİZE SANAYİ BÖLGESİ OSB SABANCI CADDESİ NO: 8 ",
        Phone: 432143123,
        Fax: 243243243,
        Sector: "KAUÇUK VE PLASTİK ÜRÜNLERİN İMALATI ",
        Email: "info@abco.com.tr",
        Website: "www.abco.com.tr"
    }
], function (err, companies) {
    // ...
});

如果您有一个存储此数据的对象，您只需这样做

Company.create(obj.json.sirketler, function (err, companies) {
    // ...
})

如果要保存 json 或 sirketler 字段，则需要更改架构。您可能需要将strict 设置为false。
