Question

我对Ember Controller中的计算属性有两个疑问。

如何重新加载模型？
我如何回复承诺？

来自Ember Controller内的计算属性。

App.MyController = Ember.ObjectController.extend({
    poll: function() {
        // Question 1
        // reload the model from server (send GET /stuff).
        return this.get('model.poll');
    }.property('model');


    second: function() {
        // Question 2
        // return a promise 
        return this.find('choices');
    }.property('model');
});

修改

我已经设置了一个使用online fake rest server的jsbin，但我无法让它工作，我将不胜感激。 http://emberjs.jsbin.com/EnOqUxe/155/edit

EDIT2

好吧你的jsbin有效，我在我的电脑上尝试了同样的事情并且ember检查员承诺标签显示了一个未决的请求，任何想法为什么？：

DS:RestAdapter#ajax GET /api/v1/games/1 Pending
