how to dynamically change whole object (inc. array) in mongodb? - mongodb

Question

I use following code to dynamically update whole object in mongoDB:
module.exports = function(req, res, next){
const Model = require('../models/' + req.body.where)
for(let i=0; i<req.body.array.length; i++){
Model.updateOne({
"_id": req.body.array[i]._id,
"user_ID": req.body.user_ID
},{
$set: req.body.array[i]
}).catch(next)
if(i+1 == req.body.array.length) res.send({})
}
}
but the code is not working, when model own array:
const mongoose = require('mongoose')
const Schema = mongoose.Schema;
const exerciseSchema = new Schema({
title: {
type: String,
required: [true, 'required!']
}
}, { _id : false })
const workout_planSchema = new Schema({
title: {
type: String,
required: [true, 'required!']
},
description: {
type: String
},
user_ID: {
type: String,
required: [true, 'required!']
},
exercises: [exerciseSchema]
})
const workout_plan = mongoose.model('workout_plan', workout_planSchema)
module.exports = workout_plan
I would like to update whole object with totally new values, staying only with the same _id.
For example , I have following value in DB:
"_id": "604a16f6cf847c1810c8fd08",
"title": "1",
"user_ID": "Test",
"exercises": [{
"title": "123"
}],
and I am sending array which looks like this:
"_id": "604a16f6cf847c1810c8fd08",
"title": "2",
"user_ID": "Test",
"exercises": [{
"title": "234"
},{
"title": "235"
}],
and the result should be same as the array I am sending. How can I change my code to reach this?
PS: Basiclly I want to make object in DB = sent object

Answer 1

so the answer is to change the main function like this:
module.exports = function(req, res, next){
const Model = require('../models/' + req.body.where)
for(let i=0; i<req.body.array.length; i++){
Model.replaceOne({
"_id": req.body.array[i]._id,
"user_ID": req.body.user_ID
},
req.body.array[i]
).catch(next)
if(i+1 == req.body.array.length) res.send({})
}
}

Answer 2

Try this one:
for( let elem of req.body.array ) {
let workout_plan = await Model.findById(elem._id);
workout_plan.title = elem.title;
workout_plan.user_ID = elem.user_ID;
workout_plan.exercises = elem.exercises;
await workout_plan.save();
}
