How to access mongoose data : Nodejs - node.js

Question

I am getting data like this:
This is the code :
User.find({ Username: user }, function(err, found_user) {
console.log('user data'+ found_user );
if(found_user.length > 0){
console.log('inside found user');
var recordings = found_user.recordings;
console.log(recordings)
for (var singleRecords in recordings){
console.log("Single record :"+singleRecords);
if(!singleRecords.isPlayed){
console.log(singleRecords.playingUrl);
twiml.play(singleRecords.playingUrl);
found_user.recordings[singleRecords].isPlayed = true;
found_user.save(function (err) {
if(err)
throw err
});
}
}
}
And this is the value of found User :
user data { Username: 'B',
__v: 2,
_id: 58ac15e4b4e1232f6f118ba3,
recordings:
[ { isPlayed: false,
playingUrl: 'http://localhost:8000/public/toplay/playing_file_1487672817599.mp3' },
{ isPlayed: false,
playingUrl: 'http://localhost:8000/public/toplay/playing_file_1487672827411.mp3' } ]
}
inside found user
in variable found_user. But it is not giving me any data inside it. Like found_user.Username gives undefined value.
I want to store that recordings array inside a variable. Any idea how to do it ?

Answer 1

find() returns an array of docs that match the criteria in the callback hence the line
var recordings = found_user.recordings;
will not work as it's expecting a Document not an array.
You could use findOne() method which returns a document as:
User.findOne({ Username: user }.exec(function(err, found_user) {
console.log('user data'+ found_user );
if (found_user) {
console.log('inside found user');
var recordings = found_user.recordings;
console.log(recordings);
}
});
