Question

我正在通過邁克爾哈特爾Ruby on Rails Tutorial工作，我一直在得到一個我無法弄清楚的失敗測試 這是一個指向代碼的鏈接，如果你倒是像code at github

這是我得到的失敗：

+1提供鏈接到您的Github上的帳戶爲你遺憾的是所提供的代碼不表示問題出在哪裏。

的問題是，在你的應用程序/視圖/佈局/ application.html.erb文件，你也行：

<title><%= full_title(yield(:title)) %></title> 

但在your views under app/views/static_pages，你沒有provide d的:title s表示是yield編輯。例如，在你的應用程序/視圖/ static_pages/about.html.erb文件，你需要添加下面一行：

<% provide(:title, 'About Us') %> 

你還需要到相關行添加到您的其他視圖下app/views/static_pages爲了讓測試通過。詳情請參閱the views under the static_pages directory in Rails Tutorial github repo。
