Michael Hartl教程v。3.2第5.1章用戶中的NoMethodError＃new Line 4

我是一個新手，我正在通過Hartl慢慢地工作。剛剛開始在Ch5上。到了5.1並將新的樣式代碼添加到application.html.erb中，並且我在瀏覽器中收到了「Static_pages＃home中的NoMethodError」。Michael Hartl教程v。3.2第5.1章用戶中的NoMethodError＃new Line 4

這裏的終端讀出：

Started GET "/static_pages/home" for 127.0.0.1 at 2012-05-31 14:02:03 +0100

的static_pages_controller

class StaticPagesController < ApplicationController 

    def home 
    end 

    def help 
    end 

    def about 
    end 

    def contact 
    end 
end

什麼都沒有成功完成Ch.3改變。所以我回去了，再次工作了第3章，所有的測試通過都是綠色的，所有的瀏覽器測試都OK，我跳回了第5章。將Hartls新代碼剪切並粘貼到views/layouts/application.html.erb中，保存該文件並獲得相同的No Method Error。

它看起來像full_title幫手是在Chapter 4開頭正確引入的。
