How to Append key: value pairs to existing Mongodb objects using Mongoose - node.js

Question

const express = require('express');
const bcrypt = require('bcryptjs');
const passport = require('passport');
const { ensureAuthenticated } = require('../config/auth');
const router = express.Router();
//User/Post model
const User = require('../models/DBmusevista');
//Welcome/register page
router.get('/', (req, res) => res.render('register'));
//Login page
router.get('/login', (req, res) => res.render('login'));
//Home page
router.get('/home', ensureAuthenticated, (req, res) => res.render('home', {user_mv: req.user}));
//Create topic page
router.get('/create-topic', ensureAuthenticated, (req, res) => res.render('create-topic', {user_mv: req.user}));
//Register handle
router.post('/', (req, res) => {
const {firstname, lastname, username, email, password} = req.body;
let errors =[];
if(!firstname || !lastname || !username || !email || !password) {
errors.push({msg: 'Please check all fields.'});
};
//Check password length
if(password.length < 6) {
errors.push({msg: 'Password should be at least 6 characters.'});
};
if(errors.length > 0){
res.render('register', {
errors,
firstname,
lastname,
username,
email,
password
});
}else {
//Validation passed
User.findOne({email: email})
.then(user => {
if(user){
//User exists
errors.push({msg: 'Email is already registered.'})
res.render('register', {
errors,
firstname,
lastname,
username,
email,
password
});
} else {
const newUser = new User({ //Check User
firstname,
lastname,
username,
email,
password
});
//Hash password
bcrypt.genSalt(10, (err, salt) =>
bcrypt.hash(newUser.password,salt, (err, hash) => {
if(err) throw err;
//Set password to hash
newUser.password = hash;
//Save user
newUser.save()
.then(user => {
req.flash('success_msg', 'You are now registered and can now log in');
res.redirect('/login');
})
.catch(err => console.log(err));
}))
}
});
}
});
//Post handle
router.post('/create-topic', (req, res) => {
let newObj = {
title: req.body.title,
category: req.body.category,
vista: req.body.vista,
description: req.body.description
}
User.updateOne({username: user_mv.username}, { $set: {post: newObj}});
res.send('Hello');
//This is the code that does not work. Anything else I've tried has not worked.
});
//Login handle
router.post('/login', (req, res, next) => {
passport.authenticate('local', {
successRedirect: '/home',
failureRedirect: '/login',
failureFlash: true
})(req, res, next);
});
module.exports = router;
const mongoose = require('mongoose');
const DBmusevistaSchema = mongoose.Schema({
firstname: {
type: String,
required: false
},
lastname: {
type: String,
required: false
},
username: {
type: String,
required: false
},
email: {
type: String,
required: false
},
password: {
type: String,
required: false
},
date: {
type: Date,
default: Date.now
}
});
const DBmusevista = mongoose.model('DBmusevista', DBmusevistaSchema);
module.exports = DBmusevista;
When an individual comes to my website the beginning page ('/') is a registration for for my site. I have a post request for my MongoDB collection that creates a 'user register' object (fname, lname, username, email, pass). Once logged in ('/home') a user can then create a new post(s) form that is located in my create-topic.ejs file('/create-topic'). I'm new to using MongoDB so my question is how can I append the post submitted (title, category, vista, description) to an array for the users' object.
I'm not sure if I should add an array (posts: []) to DBmusevistaSchema and create a Post.Schema({key: value}) in my DBmusevista file? I tried using User.findOne but I cannot get it to work. Please help.

try {
const pirs = await Pir.find();
pirs.forEach(async (pir) => {
let pir2 = new Pir();
pir.isSubmitted = false;
pir2 = pir;
const out = await pir2.save();
console.log(out);
});
} catch (err) {
next(err);
}
