用猫鼬插入多个文档

Question

I made an API with express.js, and i use mongoDB for my database and mongoose as my ODM

I really confused when i want to insert multiple document to my collection in once post request.

Here my model :

const modul = require('../config/require');
const Schema = modul.mongoose.Schema;

let TeleponSchema = new Schema({
    _pelanggan : {type: String},
    telepon: {type: String, required: true}
});

module.exports = modul.mongoose.model('telepon', TeleponSchema, 'telepon');

and here my controller

const Telepon = require('../models/telepon.model')

exports.create = (req,res) => {
    let telepon = new Telepon({
        _pelanggan : req.body.pel,
        telepon: req.body.telepon
    });

    telepon.save((err,data) => {
        if(err){
            res.send({message:'eror', detail: err});
        }else{
            res.send({message:'success', data: data})
        }
    });

}

Then i post my request with postman like this :

but the result in my document is :

that's the problem, the value of 'telepon' is in the same row and separated by comma instead of insert a new row and create a new _id

i want the result of my collection like this :

(example)

Any help and suggestion would be much appreciated

Thank you!

1) Per .save call you will only affect one document, check out insertMany to do multiple.

2) req.body.telepon is either an array of numbers, or is already just the comma delimited list of numbers; if it is an array the .toString will result in a comma delimited list anyways. So when you new up the Telepon it has both values in one property, which is what you see in the result.
