But which still acts as an ajax form? You would simply handle the response for ajax and non ajax requests using Rails' responds_to function.PHP Code:
<% form_remote_tag :controller => 'foo', :action => 'bar', :unobtrusive => true %>
# which produces
<form id="form_foo_bar" action="/foo/bar" method="post">
Sorry to tease. Stay tuned, we have something very cool to show off in the next day or two.
