How to find a model from a collection according to some attribute other than the ID?

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.

Backbone collections support the underscorejs find method, so using that should work.

things.find(function(model) { return model.get('name') === 'Lee'; });
