Mongoose populate sub-sub document

Question

I have this setup in my MongoDB

Items:

title: String
comments: [] // of objectId\'s

Comments:

user: ObjectId()
item: Ob         


        

Answer 1

One more way (easier) to do this:

Item
  .find({})
  .populate({
	path:     'comments',			
	populate: { path:  'user',
		    model: 'users' }
  })
  .exec(function(err, data){
    if (err) return handleError(err);
    res.json(data);
});
