Question

我的_header.html.erb代码：

<header class="navbar navbar-fixed-top navbar-inverse">
  <div class="container">
    <%= link_to "sample app", 'root_path', id: "logo" %>
    <nav>
      <ul class="nav navbar-nav navbar-right">
        <li><%= link_to "Home",   'root_path' %></li>
        <li><%= link_to "Help",   'help_path' %></li>
        <li><%= link_to "Log in", '#' %></li>
      </ul>
    </nav>
  </div>
</header>

＆＃34; root_path＆＃34;以上应评估为＆＃34; /＆＃34;但它并没有。我正在使用michael hartl教程

的routes.rb

Rails.application.routes.draw do
  root 'static_pages#home'
  get  '/help',    to: 'static_pages#help'
  get  '/about',   to: 'static_pages#about'
  get  '/contact', to: 'static_pages#contact'
  get  '/signup',  to: 'users#new'
  post '/signup',  to: 'users#create'
  resources :users
end

rake routes：

Richard:sample_app richard$ rake routes
   Prefix Verb   URI Pattern               Controller#Action
     root GET    /                         static_pages#home
     help GET    /help(.:format)           static_pages#help
    about GET    /about(.:format)          static_pages#about
  contact GET    /contact(.:format)        static_pages#contact

          POST   /signup(.:format)         users#create
    users GET    /users(.:format)          users#index
          POST   /users(.:format)          users#create
 new_user GET    /users/new(.:format)      users#new
edit_user GET    /users/:id/edit(.:format) users#edit
     user GET    /users/:id(.:format)      users#show
          PATCH  /users/:id(.:format)      users#update
          PUT    /users/:id(.:format)      users#update
          DELETE /users/:id(.:format)      users#destroy

Answer 1

您不应将/括在引号中，因为它是一个评估为<%= link_to "sample app", root_path, id: "logo" %>的路径助手方法。这样做：

"#{root_path}"

或者如果您喜欢使用引号，请使用<section id="education" name="education"></section> <div id="myeducation1"> <div class="container"> <div class="row"> <div class="col-xs-6"> <p>Donec id elit non mi porta gravida at eget metus.Donec id elit non mi porta gravida at eget metus.Donec id elit non mi porta gravida at eget metus.</p> </div> <div class="col-xs-6"> <p>Donec id elit non mi porta gravida at eget metus.Donec id elit non mi porta gravida at eget metus.Donec id elit non mi porta gravida at eget metus.</p> </div> </div> </div> </div> </section>

Answer 2

您的root位于http://<host>/而不是http://<host>/root_path。 root_path是返回url而不是路径本身的方法的名称。

Answer 3

我发现了这个问题。在“/views/layout/_header.html.erb”和_footer.html.erb中，我使用“root_path”和“about_path”周围的引号而不仅仅是变量。检查所有类似的变量以确保您没有引用它们

没有路由匹配GET root_path
