Unable to update mongodb document with nested object property from node api - node.js

Question

I have the following mongodb document:
{
"_id" : ObjectId("5ee95b41ca023a3deb252ef2"),
"uid" : "jdoe",
"name" : "John Doe",
"employee_hire_date" : "2012-06-20",
"three_month_review_target" : "2012-09-20",
"six_month_review_target" : "2012-12-20",
"three_month_review_status" : {
"is_scheduled" : null,
"is_team_member_emailed" : null,
"is_review_executed" : null,
},
"six_month_review_status" : {
"is_scheduled" : null,
"is_team_member_emailed" : null,
"is_review_executed" : null,
}
}
I would like to update the three_month_review_status.is_scheduled nested property to true. I am using a put request to accomplish this:
const mongoose = require('mongoose');
const Reviews = require('../modules/reviews/models/reviews');
module.exports = (app) => {
app.put('/api/reviews/isScheduled', async (req, res) => {
console.log('body', req.body)
console.log('uid', req.body.uid)
console.log('is_scheduled', req.body.three_month_review_status.is_scheduled)
Reviews.findOneAndUpdate( { 'uid': req.body.uid }, { $set: { 'three_month_review_status.is_scheduled': req.body.is_scheduled }}, (err, result) => {
if (err) {
console.log('error', err)
}
else {
console.log('updated', result);
res.status(200).send(result);
}
} )
});
}
To test this, I execute this PUT request through Postman with the following request body:
{
"uid": "jdoe",
"three_month_review_status": {
"is_scheduled": "true"
}
}
However, when the request gets executed, the other two nested objects are removed and is_scheduled remains null. This is the document after the request is executed:
{
"_id" : ObjectId("5ee95b41ca023a3deb252ef2"),
"uid" : "jdoe",
"name" : "John Doe",
"employee_hire_date" : "2012-06-20",
"three_month_review_target" : "2012-09-20",
"six_month_review_target" : "2012-12-20",
"three_month_review_status" : {
"is_scheduled" : null
},
"six_month_review_status" : {
"is_scheduled" : null,
"is_team_member_emailed" : null,
"is_review_executed" : null,
}
}
What am I doing wrong? Here is my reviewsSchema for more context:
const { Schema, model } = require('mongoose');
const reviewsSchema = new Schema({
uid: String,
name: String,
employee_hire_date: String,
three_month_review_target: String,
six_month_review_target: String,
three_month_review_status: {
is_scheduled: Boolean,
is_team_member_emailed: Boolean,
is_review_executed: Boolean,
},
six_month_review_status: {
is_scheduled: Boolean,
is_team_member_emailed: Boolean,
is_review_executed: Boolean,
},
})
const Reviews = model('review', reviewsSchema);
module.exports = Reviews;

Answer 1

In Mongoose you don't need to specify the $set. Also based on the sample JSON that you send from the postman instead of req.body.is_scheduled you need to provide req.body.three_month_review_status.is_scheduled in the query. Also, need to add {new: true} if you want the findOneAndUpdate to return the updated document
So you can update the query like
Reviews.findOneAndUpdate(
{ uid: req.body.uid },
{
"three_month_review_status.is_scheduled":
req.body.three_month_review_status.is_scheduled,
},
{ new: true },
(err, result) => {
if (err) {
console.log("error", err);
} else {
console.log("updated", result);
res.status(200).send(result);
}
}
);
