mongoose sub document array change value
I got a mongoose query where I want to change a comment. I receive the commentid from a react app. But it doesn't work, what could be the problem?
An example comment array follows
"comments": [
{
"createdAt": "2018-11-22T08:28:36.881Z",
"_id": "5bf668b4001de72dc089c849", // commentid
"comment": "111111111111",
"username": "kohahn21"
},
....
]
What I have tried:
edit = await Post.update(
{ 'comments._id' : commentid },
{ '$set' : { 'comments.$.comment' : comment } },
{ new: true }
);
ctx.body = edit;
ctx.body
{
"n": 1,
"nModified": 1,
"ok": 1
}
Post Schema
const Comment = new Schema({
createdAt: { type: Date, default: Date.now },
username: String,
comment: String
});
const Post = new Schema({
username: String,
comments: {
type: [Comment],
default:
},
});
module.exports = mongoose.model('Post',Post);
I would like to receive comments, which is a modified comment layout. What should I do?

Your syntax looks correct. But instead of 'items' it should be 'comments'.
Try Post.update( { 'comments._id' : commentid }, {'$set' : { 'comments.$.comment' : comment } });
btw the new flag is only available for find-and operators.

Use findAndModify instead of update.
