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

Question

I have a model with several object:

//Model
Friend = Backbone.Model.extend({
    //Create a model to hold friend attribute
    name: null,
}); 

//objects
va         


        

Answer 1

The simplest way is to use "idAttribute" option of Backbone Model to let Backbone know the that you want to use "name" as your Model Id.

 Friend = Backbone.Model.extend({
      //Create a model to hold friend attribute
      name: null,
      idAttribute: 'name'
 });

Now you can directly use Collection.get() method to retrieve a friend using his name. This way Backbone does not loop through all of your Friend models in the Collection but can directly fetch a model based on its "name".

var lee = friends.get('Lee');
