title: Why does "link_to" work but not "button_to"
body: <p>Why would this work?</p>
  
  <pre><code>&lt;%= link_to "New Item", new_site_care_path, {:class =&gt; "button_bottom"} %&gt;
  </code></pre>
  
  <p>And this (the only change is from link_to to button_to)... </p>
  
  <pre><code>&lt;%= button_to "New Item", :url =&gt; new_site_care_path, {:class =&gt; "button_bottom"} %&gt;
  </code></pre>
  
  <p>...produces:</p>
  
  <pre><code>No route matches "/site_cares/new"
  </code></pre>
  
  <p><em><strong>UPDATE - ROUTE INFO -</em></strong> 
  route file:</p>
  
  <pre><code>resources :site_cares, :except =&gt; :show
  </code></pre>
  
  <p>rake routes:</p>
  
  <pre><code>new_site_care GET /site_cares/new(.:format) {:action=&gt;"new", :controller=&gt;"site_cares"}
