Why is this current_page? call giving me a no route error for a route that exists?

Question

In my application.html.erb, I have this:

      <% 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 %>

Pay special attention the elsif current_page?... line. That's where the error is being generated.

I visit Question#Index, and I get this error in my server log (error is at the bottom):

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

However, in my routes.rb I have this:

resources :jobs

And my rails/info/routes (aka web version of rake routes) has this:

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

I have this in my JobsController.rb

  def show
  end

I have restarted my server a few times, and still no dice.

Thoughts?
