backbone.js models pointing to same instance of nested model

Question

Using backbone.js, here is a quick test to demonstrate the problem I am facing with nested models.

Preface I have a Obj Model that

Answer 1

With:

var Obj = Backbone.Model.extend({
    defaults: {
        obj1    : new Obj1(),
        obj2    : new Obj2()
    }
})

You are saying that you want all objects created with "Obj" to have the same "obj1" and "obj2" values, use:

var Obj = Backbone.Model.extend({
    initialize: function() {
        this.obj1 = new Obj1();
        this.obj2 = new Obj2();
    }
});
