Javascript ember教程入门：在'；显示模型数据'；引起错误

所以请提前原谅我，我对ember显然是全新的（对JS来说也是全新的。我正在一行一行地学习增强版入门教程，（除非我错过了什么）当我的浏览器决定只渲染背景时。我回过头来，注意到它在按照此处的指示更改路由器后立即发生：

我在这里提交并推送到github：

^如果希望看到差异，则在浏览器中呈现的第一次提交将很好，第二次提交将被中断

这是我的控制台输出：

Uncaught ReferenceError: Todos is not defined todo.js:1

This is the router.js that breaks the code:
Todos.Router.map(function () {
  this.resource('todos', { path: '/' });
});

Todos.TodosRoute = Ember.Route.extend({
  model: function () {
    return this.store.find('todo');
  }
});

非常感谢您的任何想法。

这是该版本的余烬数据（可能是余烬/余烬数据）中的一个缺陷

Todos.Todo = DS.Model.extend({
  title: DS.attr('string'),
  isCompleted: DS.attr('boolean')
});

Todos.Todo.FIXTURES = [
 {
   id: 1,
   title: 'Learn Ember.js',
   isCompleted: true
 },
 {
   id: 2,
   title: '...',
   isCompleted: false
 },
 {
   id: 3,
   title: 'Profit!',
   isCompleted: false
 }
];
