        }
    }
]
</code></pre>

<p>for example WorkshopId must be changed to workshopid, I have a function in node js that query a collection in mongodb and return the json : </p>

<pre><code>getWorkshops: function (db, response) {
                db.collection('Workshops').find().toArray(function (err, results) {
                    var convertedArr = [];
                    //convert the json.
                    response.send(JSON.stringify(convertedArr));
        });
</code></pre>

<p>any help?</p>
