Relationship id return to server a String and not a Int!

Okay, I tried it on my own using a serializer object:

export default DS.RESTSerializer.extend({
    serialize: function(snapshot, options) {
        var json = this._super(snapshot, options);
        json.entity = parseInt(json.entity);
        return json;
    }
});

However, I do not know if this is the best solution … should also be noted that the documentation of code seems out of date, since the id displayed as numbers and not as strings.

:wink:
