Question

Should the state of a backbone.js model be fully stored in it’s attributes?

Can you duplicate a models state by passing its attributes into another model?

Thanks

Answer 1

Yes and Yes.

calling .toJSON() on a model duplicates it’s attributes, and this can be passed into another model:

var m1 = new MyModel({foo: "bar", baz: "widget"});
var attrs = m1.toJSON();
var m2 = new MyModel(attrs);

console.log(m2.get("foo")); //=> "bar"
console.log(m2.get("baz")); //=> "widget"
