title: Ruby on Rails routes: resources on collection
body: <p>I need a link, which would point to all jobs, tagged as PHP. This structure makes sense to me:</p>
  
  <blockquote>
    <p>site.com/jobs/skills/php</p>
  </blockquote>
  
  <p>How do I do this in Rails?</p>
  
  <pre><code>  resources :jobs do
      collection do
        resources :skills, as: :find_by_skill
      end
    end
  </code></pre>
  
  <p>However, this does not work, when I try to call the jobs_find_by_skill(skill) helper. Where is a problem? If this cannot be done, could you suggest a better URL structure for this kind of purpose?</p>
