Answer 1

您的申请助手缺少end。

def full_title(page_title) 
    base_title = "Ruby on Rails Tutorials Sample App" 
    if page_title.empty? 
    base_title 
    else 
    "#{base_title} | #{page_title}" 
    end 
end 

您如何定义路线存在问题。 Rails路由都是小写的。

SampleApp::Application.routes.draw do 
    get "home",  :to => "static_pages#home" 
    get "help",  :to => "static_pages#help" 
    get "about", :to => "static_pages#about" 
    get "contacts", :to => "static_pages#contacts" 
end 

因此，你的路线有关网页应about_path代替。
