How to add an object in array in MongoDB?
0
I have this schema:
var PostSchema = new Schema({
title: String,
description: String,
content: String,
image: String,
category: String,
url: String,
views: {
type: Number,
default: 0
},
comments: [
{
username: String,
email: String,
comment: String
}
]
});
Now I need to put new objects in comments array. I've made this method, but obviously it doesn't work :)
router.put('/blog/:url/add-comment', (req, res) => {
let db = req.db
Post.updateOne({ 'url': req.params.url }, {$push: {comments: {
'username': req.body.comments.username,
'email': req.body.comments.email,
'comment': req.body.comments.comment
}}})
Where did I go wrong?

Presumablyreq.body.commentsis possibly an "array" within the content being sent/received. In this case it would bereq.body.comments[0].usernameetc for each element. Or just{ $push: { comments: { $each: req.body.comments } } }. But the necessary detail is really missing from the question, so it should be updated to show what is being sent.
