node.js - 使用nodejs将多个值插入mongodb中的属性

Question

您好，我使用以下代码将值插入到我的 mongodb 中

var mongoose = require('mongoose');
var db = mongoose.createConnection('mongodb://localhost/TruJuncSVC1');
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function callback () {

console.log('connection opened in Mongodb with SAMPLE TESTING Database')
var schema = new mongoose.Schema({Response: String,Id:String,Name:String,News:String,Details:String});

var SvcOrch = db.model('SvcOrch', schema);
var data = new SvcOrch({ 'Response': 'DailyLoad','Id':'S3000981','Name':'Stears','News':'Mens Boutiques Try New Tactics for Winning Loyal CustomersTradition Finds New Biz in Old Font','Details':'Stears Roebuck and Co. or Stears, is an American chain of department stores,[2] which was founded by Richard Warren Sears and Alvah Curtis Roebuck in the late 19th century. Formerly a component of the Dow Jones Industrial Average, Stears bought out Kmart[3] in early 2005, creating the Stears Holdings Corporation.'});


                        data.save(function (err) {
                        if (err) return handleError(err);
                        // saved!
                        console.log('\nResponse data saved in MongoDB')
                        })
                        });
                        });

我能够为每个属性插入一个值，我需要为单个属性保存多个值，比如 id 应该有 2 或 3 个值，所有属性都相同。任何关于如何进一步进行的想法都会很多有帮助。提前致谢

如果需要存储单个属性的多个值，请将其声明为数组。

例如，如果您想在每个文档中存储多个 news 项，您可以将架构更改为:

var schema = new mongoose.Schema({
    Response: String,
    Id: String,
    Name: String,
    News: [String],
    Details: String
});

并创建具有多个新闻值的新项目，如下所示:

var data = new SvcOrch({
    Response: 'DailyLoad',
    Id: 'S3000981',
    Name: 'Stears',
    News: ['News item 1', 'News item 2'],
    Details: 'More details...'
});
