在 Javascript 上使用 Mongoose 将对象数组保存到 MongoDB

Question

I have this data (json):

 var unique = [ {"name":"John", "number":"4132321234"}, {"name":"Jack", "number":"451232421234"}, {"name":"Maddy", "number":"12314124"}, {"name":"Alex", "number":"213468316"} ]

What I want to do, is save this data to my mongoDB collection, with the following schema (using mongoose):

 const mongoose = require('mongoose') const Schema = mongoose.Schema const nameSchema = new Schema({ name: { type: String, required: true, }, number: { type: String, required: true, }, }); const Name_db = mongoose.model('Name_db', nameSchema) module.exports = Name_db;

I wrote a loop, to attempt to do this:

 for (var k = 1; k < unique.length; k++) { var name_mongo = new Name_db({ name: unique[k].name, number: unique[k].number, }, ) console.log(unique[k].name) } name_mongo.save().then(results => { res.send(results) }).catch(err => { console.log(err);})

This doesn't work because right now it is only sending data once to mongo DB, meaning only of the arrays is actually being sent over, instead of all 3 of them being sent to mongoDB.

Would appreciate any help, thank you for the time.

Answer 1

Name_db.insertMany(unique)
    .then((result) => console.log("Inserted", result))
    .catch((error) console.log(error));

or

const result = await Name_db.insertMany(unique); // remember to decorate the function async
