Question

在我的application.html.erb中，我有这个：

      <% if current_page?(controller: "questions", action: "index") || current_page?(controller: "jobs", action: "index") %>
        <%= "This is the IF for #{controller_name} and #{controller.action_name}" %>
            <%= yield %>
      <% elsif current_page?(controller: "jobs", action: "show") %>
        <%= "This is the ELSIF for #{controller_name} and #{controller.action_name}" %>
          <div class="wrapper wrapper-content article">
            <%= yield %>
          </div>
      <% else %>
      <% end %>

特别注意elsif current_page?...行。这就是产生错误的地方。

我访问Question#Index，我在服务器日志中收到此错误（错误位于底部）：

ActionController::UrlGenerationError - No route matches {:action=>"show", :controller=>"jobs"}:

然而，在我的routes.rb我有这个：

resources :jobs

我的rails/info/routes（又名rake routes的网络版）就是这样：

jobs_path   GET /jobs(.:format) jobs#index    
           POST /jobs(.:format) jobs#create
new_job_path GET /jobs/new(.:format) jobs#new 
edit_job_path GET /jobs/:id/edit(.:format) jobs#edit
job_path    GET /jobs/:id(.:format) jobs#show
          PATCH /jobs/:id(.:format) jobs#update
          PUT   /jobs/:id(.:format) jobs#update
         DELETE /jobs/:id(.:format) jobs#destroy

我在JobsController.rb

中有这个

  def show
  end

我已经重启了我的服务器几次，但仍然没有骰子。

思想？

为什么这是current_page？打电话给我一条存在路线的无路线错误？
