Javascript 流星及；铁路由器{{>；产量}未拉入模板

编辑：我运行了流星添加ejson，这就解决了它

我松散地跟随DiscoveryMeteor来构建我自己的应用程序。我刚刚实现了iron router，现在我的模板没有拉入数据。我检查了数据库，数据就在那里。答案可能是显而易见的，但我已经把代码读了100遍了，还是弄不明白。如果我将{{>yield}改回{{>dealsList}，效果很好

Layout.html

<template name="layout">
  <div class="container">
    <header class="navbar navbar-default" role="navigation">
      <div class="navbar-header">
        <a class="navbar-brand" href="{{pathFor 'dealsList'}}">swigFU</a>
      </div>
    </header>
    <div id="main">
      {{> yield}}
    </div>
  </div>
</template>

deals\u list.html

<template name="dealsList">
  <div class="posts page">
    {{#each deals}}
      {{> dealItem}}
    {{/each}}
  </div>
</template>

您必须在控制台中执行此操作：meteor add ejson。看看这个：谢谢，伙计，是的，我把头发拔了几个小时后才发现。你觉得我的评论有用吗？那样的话，你能标记一下吗？谢谢

<template name="dealsList">
  <div class="posts page">
    {{#each deals}}
      {{> dealItem}}
    {{/each}}
  </div>
</template>
