Michael Hartl教程v。3.2第5.1章用户中的NoMethodError＃new Line 4

我是一个新手，我正在通过Hartl慢慢地工作。刚刚开始在Ch5上。到了5.1并将新的样式代码添加到application.html.erb中，并且我在浏览器中收到了“Static_pages＃home中的NoMethodError”。Michael Hartl教程v。3.2第5.1章用户中的NoMethodError＃new Line 4

这里的终端读出：

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

什么都没有成功完成Ch.3改变。所以我回去了，再次工作了第3章，所有的测试通过都是绿色的，所有的浏览器测试都OK，我跳回了第5章。将Hartls新代码剪切并粘贴到views/layouts/application.html.erb中，保存该文件并获得相同的No Method Error。

它看起来像full_title帮手是在Chapter 4开头正确引入的。
