我在海上，如果有最新版本的 Ember 帮助，我将不胜感激。使用todo 示例，我尝试在以下改编的http://jsfiddle.net/5HMzu/3/中包含路由和 DS 模型
当我在车把模板中使用#each 控制器时，输出如预期的那样；用 CollectionView 替换它并尝试将其绑定到数据源，没有任何输出。
插入的代码：
App.PersonCollectionView = Ember.CollectionView.extend({
itemViewClass: "App.ListOfPeopleTemplateView",
emptyView: Ember.View.extend({
template: Ember.Handlebars.compile("Oh dear, the collectionView is empty")
}),
contentBinding: "App.listOfpeopleTemplateController"
});
结果：“天哪，collectionView 是空的”
模板
<body>
<script type="text/x-handlebars">
<!-- an attempt to show the data template 'listOfPeopleTemplate' using a CollectionView -->
{{view App.PersonCollectionView}}
</script>
<script type="text/x-handlebars" data-template-name="listOfPeopleTemplate">
{{test}}
<!-- This was working before I removed the #each and tried to use a CollectionView -->
<!-- {{#each controller}} -->
<fieldset>
<label {{bindAttr for="view.tbFullName.elementId"}}>Full Name</label>
{{view App.DetailTextField viewName="tbFullName" placeholder="Full Name" valueBinding="fullName" readonly="readonly"}}
<br/>
<label {{bindAttr for="view.tbFirstName.elementId"}} class="RequiredLabel">First Name</label>
{{view App.DetailTextField viewName="tbFirstName" valueBinding="firstName"}}
<br/>
<label {{bindAttr for="view.tbSurname.elementId"}} class="RequiredLabel">Surname</label>
{{view App.DetailTextField viewName="tbSurname" placeholder="surname" valueBinding="surname"}}
<br/>
</fieldset>
<!-- {{/each}} -->
</script>
