title: Nested resource and restricting the Routes Created :only and :except
body: <p>Good day all,</p>
  
  <p>Can someone kindly assist me with nested resources and its best practice.</p>
  
  <p>I would like to restrict my <code>:events</code> route to only <code>:show</code> and <code>:index</code>, is this the correct way of doing it?</p>
  
  <pre><code>resources :events do
      resources :registrations, :except =&gt; [:index]
  end
  
  resources :events, :only =&gt; [:index, :show]
  </code></pre>
  
  <p>Is this the best way or the way more Rubyist would handle such thing? I've added two lines of <code>resources :events</code> or is there a way to combine it all in 1 block?</p>
  
  <p>Thanks in advance.</p>
