I have a model with several object:

//Model

Friend = Backbone.Model.extend({

    //Create a model to hold friend attribute

    name: null,

}); 



//objects

var f1 = new Friend({ name: Lee });

var f2 = new Friend({ name: David});

var f3 = new Friend({ name: Lynn});

and also, I will add these friends object to a collection:

//Collection

Friends = Backbone.Collection.extend({

    model: Friend,

});



Friends.add(f1);

Friends.add(f2);

Friends.add(f3);

and now I want to get a model according to the name of the Friend. I know that I can add an ID attribute to achieve this. But I think there should have some more simple way to do this.
