Suppose I have 2 Schema's in Mongoose that look like this:
var movieSchema = mongoose.Schema({
name: String,
type: String
});
var moviePlaylistSchema = mongoose.Schema({
name: String,
movies: [{type: mongoose.Schema.Types.ObjectId, ref: 'Movie'}]
});
var Movie = mongoose.model('Movie', movieSchema);
var MoviePlaylist = mongoose.model('MoviePlaylist', moviePlaylistSchema);
If a query was made along the following lines:
MoviePlaylist.find({}).populate('movies').exec(function(err, res) {
if (err) console.log('err', err);
else {
console.log('res', res);
res.forEach(function(elem, index) {
console.log('elem.name', elem.name);
});
}
});
Would the order of the elements in the array be maintained? The objective here is to allow the user to maintain a playlist order of their movies. If, when the "populate" method fires, the array order of Movie object Ids is not maintained, then this will not serve my purpose. Hence thought I'd ask someone who is more knowledgeable in this area.
If this works, then I have another task which is allowing the user to change the order of movies in the playlist, which should be straight forward by allowing the movie object id index to be swapped in the array.
Thanks for your help in advance.
