Post a whole form contents back in an AJAX call in Ruby on Rails

Rails has a ready made call which facilitates passing the contents of all the elements in a form in an AJAX call with the call form_remote_tag

form_remote_tag :html => { :action => url_for(:controller => "some", :action => "place") }

However, the problem with the above method is you can not pass the name of the form into the call, so if you have multiple forms on your page, this is the way to do it:

<form name='logon' id='logon'>
<input name='name' />
<input type='password' name='pass' />
<%= link_to_remote "Log me in",
:url => { :action => 'authenticate' },
:with => "Form.serialize($('logon'))",
