Question

我正在开发一个向用户显示中文字符的flashcard应用程序。我有一个包含所有属性的App.User类设置，但是我很难跟踪试用属性，它跟踪用户暴露于特定字符/正弦图的次数。

应用程序控制器应该将当前登录的用户及其详细信息存储为属性。但我似乎无法掌握试验属性中的对象或如何在ember和ember数据中执行此操作。我读了一些关于扩展支持的属性类型的内容，但老实说我不知道如何使其工作。（http://www.kaspertidemann.com/representing-objects-in-ember-data）最终REST-api php-backend将提供数据，但是现在我使用ember数据的fixtures.adapter在我的应用程序中测试它。非常感谢任何帮助！提前完成。

PS：我尽量做到尽可能完整，但如果有什么不清楚，请告诉我，我会提供更多细节！

// application controller
    App.ApplicationController = Ember.ArrayController.extend({

    login: function(){
        if ((this.get('particularUser').getEach('hed_password') == _password)){
        // Code to store all the App.user info on the controller.
        // I figured I just set the currentUser property to the object, 
        // but I don't know how to get to the currentUser.trials property.
        this.set('currentUser', this.get('particularUser'));
        var _trialsObject = this.get('currentUser').getEach('trials');
        for (var key in _trialsObject) {

// Router and Routes

    model: function () {
        return this.store.find('user');

// The trials property is an object which should keep count of the number fo times the user has seen the flashcard with this character/sinogram
(function () {
    'use strict';

    App.User = DS.Model.extend({
        id: DS.attr('number'),
        username: DS.attr('string'),
