您沒有任何'content_for更多信息：title'在contact.html.erb，所以你的標題標籤不應該包含蝨你期望 – apneadiving

我是不跟隨你抱歉。你可以請嘗試再解釋一次嗎？ – lfkwtz

你的'yield（：title）'不會做任何事情，除非你在'contact.html.erb'中添加'content_for：title' – apneadiving

你的測試失敗了，因爲你的應用程序佈局得到題，但你是不是在任何地方設置標題。當您在視圖中看到yield :something時，例如對於標題，這意味着該視圖將呈現所知道的有關「：something」的任何內容。在你的情況，標題正在通過yieled如下：

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

爲了告訴Rails你想要什麼樣的內容「稱號」屈服，你需要設置它在你的觀點：

content_for(:title) { 'My Title'}

它可以是乏味的在每個視圖重複這一點，所以很多人會爲標題幫手：

module ApplicationHelper 
    def title(page_title = '') 
    content_for(:title) { page_title } 
    end 
end

然後在你看來，你可以這樣做：

<%= title 'My Title' %>

退房Railscast #30對這種技術
