如何在IndexController中更新/编辑特定的Person？

App.Person=DS.Model.extend({
        name:DS.attr('string'),
        iminus:DS.attr(),
        iplus:DS.attr()
    });

    App.Person.FIXTURES=[
        {
            id:1,
            name:'M',
            iminus:[{amount:50,pers:'A'}],
            iplus:[]
        },
        {
            id:2,
            name:'An',
            iminus:[{amount:20,pers:'Mo'}],
            iplus:[]
        }
    ];
    App.IndexRoute=Ember.Route.extend({
        model:function(){
            return this.store.findAll('person');
        }
    });
    App.IndexController=Ember.ArrayController.extend({
    actions:{
        createNew:function(){
            //Access and Update a person record based on name
        }
    }
    });

如何基于IndexController中的名称访问和更新人员记录

var App = Ember.Application.create();

App.FixtureAdapter = DS.FixtureAdapter.extend({
    queryFixtures: function (records, query, type) {
        return records.filter(function (record) {
            for (var key in query) {
                if (!query.hasOwnProperty(key)) {
                    continue;
                }
                var value = query[key];
                if (record[key] !== value) {
                    return false;
                }
            }
            return true;
