Ember model to json

Question

I am looking for an efficient way to translate my Ember object to a json string, to use it in a websocket message below

/*
 * Model
 */

App.node = Ember.Obj

I modified @Kevin-pauli solution to make it works with arrays as well:

App.Jsonable = Ember.Mixin.create({
    getJson: function() {
        var v, json = {}, inspectArray = function (aSome) {
            if (Ember.typeof(aSome) === 'array') {
                return aSome.map(inspectArray);
            }
            if (Jsonable.detect(aSome)) {
                return aSome.getJson();
            } 
            return aSome;
        };
        for (var key in this) {
            if (this.hasOwnProperty(key)) {
                v = this[key];
                if (v === 'toString') {
                    continue;
                } 
                if (Ember.typeOf(v) === 'function') {
                    continue;
                }
                if (Ember.typeOf(v) === 'array') {
                    v = v.map(inspectArray);
                }
                if (App.Jsonable.detect(v))
                    v = v.getJson();
                json[key] = v;
            }
        }
        return json;
    }
});

I also made some further modification to get the best of both worlds. With the following version I check if the Jsonable object has a specific property that informs me on which of its properties should be serialized:

App.Jsonable = Ember.Mixin.create({
    getJson: function() {
        var v, json = {}, base, inspectArray = function (aSome) {
            if (Ember.typeof(aSome) === 'array') {
                return aSome.map(inspectArray);
            }
            if (Jsonable.detect(aSome)) {
                return aSome.getJson();
            } 
            return aSome;
        };
        if (!Ember.isNone(this.get('jsonProperties'))) {
            // the object has a selective list of properties to inspect
            base = this.getProperties(this.get('jsonProperties'));
        } else {
            // no list given: let's use all the properties
            base = this;
        }
        for (var key in base) {
            if (base.hasOwnProperty(key)) {
                v = base[key];
                if (v === 'toString') {
                    continue;
                } 
                if (Ember.typeOf(v) === 'function') {
                    continue;
                }
                if (Ember.typeOf(v) === 'array') {
                    v = v.map(inspectArray);
                }
                if (App.Jsonable.detect(v))
                    v = v.getJson();
                json[key] = v;
            }
        }
        return json;
    }
});

I am using this little tweak and I am happy with it. I hope it'll help others as well!

Thanks to @pangratz and @Kevin-Pauli for their solution!
