title: form_tag with date_select in rails3
body: <p>How can I pass the selected date to a date_select in a form_tag</p>
  
  <p>I would like something like </p>
  
  <pre><code>date_select_tag(object_name, value, options = {}, html_options = {})
  </code></pre>
  
  <p>Is that possible?
  Thanks!</p>
