灰烬嵌套路线和模型完全不渲染

Question

我可以显示“帮助主题”标题​​，但是没有定义的“ FIXTURES 。 {{#each model}}不会呈现。 这是我第一次使用Ember，因此任何事情（实际上是任何事情）都将有所帮助，因为我没有在浏览器调试器中收到任何错误消息。

App.js

App.Router.map(function () {
    this.resource('home', { path: "/Index" });
    this.resource('agents', { path: "/Agents" });
    this.resource('topics',  function() {
        this.resource('topic', {path: '/topic/:topic_id'})
    });  
    this.resource('contacts', { path: "/Contacts" });
});

App.TopicRoute = Ember.Route.extend({
    model: function () {
        return App.Topic.find();
    }
})

App.Topic = DS.Model.extend({
    title: DS.attr('string'),
    info: DS.attr('string')
});

App.Topic.FIXTURES = [{
    id: 1,
    title: "Periscope",
    info: "Periscope is a read-only application pulling information from D3."
}, {
    id: 2,
    title: "Second post",
    info: "ASP.NET MVC 4 is a framework for building scalable, standards-based web applications using well-established design patterns and the power of ASP.NET and the .NET Framework."
}, {
    id: 3,
    title: "Ember.js",
    info: "Ember.js is designed to help developers build ambitiously large web applications that are competitive with native apps."
}];

尝试像这样更改路线：

App.TopicsRoute = Ember.Route.extend({
  model: function () {
    return App.Topic.find();
});

希望能帮助到你。
