title: Button_to uses POST Link_to uses GET, why? ROR
body: <p>I've ran into a ror problem using the link_to. Why does my link to use the GET method and my button_to use the POST method, after I specified my "method"=>"post" within the link_to parameters? </p>
  
  <p>View:</p>
  
  <pre><code>&lt;%= button_to "pdf", :action =&gt; 'getquote' %&gt;
  &lt;%= link_to 'pdf', {:controller =&gt; 'inventories', :action =&gt; 'getquote', :method =&gt; :post } %&gt;
  </code></pre>
  
  <p>Controller Method:</p>
  
  <pre><code>def getquote
  @cart = find_cart
  respond_to do |format|
  format.pdf
  end
  end
  </code></pre>
  
  <p>Terminal Output (Button/Link, respectively): </p>
