title: remote form_tag in rails3 without a named route
body: <p>what is the proper incantation to make this actually post asynchronously?</p>
  
  <pre><code>form_tag :controller =&gt; :magic, :action =&gt; :search, :method =&gt; post, :remote =&gt; true do
  </code></pre>
  
  <p>method=post and remote=true just get squashed on the end of the url instead of actually making it an ajax post.</p>
