how to use nested object as a ref in mongoose - mongodb

Question

I have two schemas user and note-
user schema
import mongoose from 'mongoose';
const userSchema = mongoose.Schema({
id: {
type: String,
},
name: {
type: String,
required: true,
},
email: {
type: String,
required: true,
unique: true,
},
password: {
type: String,
required: true,
},
notes: [
{
type: mongoose.Types.ObjectId,
ref: 'Note',
},
],
folders: {
type: [
{
name: {
type: String,
},
notes: [
{
type: mongoose.Types.ObjectId,
ref: 'Note',
},
],
},
],
default: [
{ name: 'My Notes', notes: [] },
{ name: 'Todos', notes: [] },
{ name: 'Projects', notes: [] },
{ name: 'Journals', notes: [] },
{ name: 'Reading list', notes: [] },
],
},
});
const User = mongoose.model('User', userSchema);
export default User;
note schema
import mongoose from 'mongoose';
const noteSchema = new mongoose.Schema({
id: {
type: String,
required: true,
},
modify_date: {
type: String,
required: true,
},
modify_time: {
type: String,
required: true,
},
tags: [
{
id: {
type: String,
required: true,
},
text: {
type: String,
required: true,
},
},
],
created_by: {
type: mongoose.Types.ObjectId,
ref: 'User',
required: true,
},
folder: {
type: String, //can I use ref from user?
},
title: {
type: String,
},
body: {
type: String,
required: true,
},
time_stamp: {
type: Date,
required: true,
},
});
const Note = mongoose.model('Note', noteSchema);
export default Note;
I have searched but could not find anything. I want to use the nested folder object from user schema as a ref in note schema; so, whenever I change or update a folders name all the notes get the updated value. Is it possible?
If not should I make a separate folder schema and add ref of folder schema in both note and user? How can I achieve that, any suggestion might be very helpful?
