Cannot see JSON field in GET (mongoose) response

Question

I have this JSON document (as shown in mongolab ):

{
    "_id": {
        "$oid": "566e8673eb862d165fef7171"
    },
    "street": "Dizingof",
    "buildingNumber": 33,
    "apartmentNumber": 63,
    "beds": 3,
    "owner": {
        "_id": {
            "$oid": "564374944cb813541afc193a"
        },
        "local": {
            "password": "$2a$08$PtZrvLY7MWSi44gMDSjLJ.u4x.IOXIkRFZYfQhAwt.5vSIXpCYjX6",
            "email": "[e-mail]"
        },
        "__v": 0
    }
}

Which field ownerin his scheme is defined as:

owner           :  {
                type: Schema.ObjectId,
                ref: 'User'
        }

And when I execute http.getto get a listing, I get back:

{
  "_id": "566e8673eb862d165fef7171",
  "street": "Dizingof",
  "buildingNumber": 33,
  "apartmentNumber": 63,
  "beds": 3,
  "imagesAndCount": [],
  "UsersAndQuestions": []
}

Why can't I see / use the field owner? I need this to manipulate my HTML document.

Edit: this is the corresponding GET in routes.js:

app.get('/api/listing/:street/:buildingNumber/:apartmentNumber', function (req, res) {
        Listing.findOne(
            {
                "street": req.params.street,
                "buildingNumber": req.params.buildingNumber,
                "apartmentNumber": req.params.apartmentNumber
            }
            , function (err, listing) {
                if (err) { return next(err); }
                res.json(listing);
            });
    });

In addition, I filled out the field ownerby doing the following:

var myUser = db.users.findOne()
db.listings.insert({"street" : "Dizingof", "buildingNumber" : 33, "apartmentNumber" : 63, "beds": 3, "owner": myUser})

Your problem is this

owner :{
    type: Schema.ObjectId,
    ref: 'User'
}

Mongoose , , populate ( ), .

, 4.2 , - :

http://mongoosejs.com/docs/subdocs.html#altsyntax

var ownerSchema= new Schema({ name: 'string', otherProperty: 'string' });

var parentSchema = new Schema({
  owner: ownerSchema
});
