Form submitting to /foo/bar

Hi guys. I have a form which submits to the “show” action of a
controller. However, when the form is submitted, it directs the
browser to URLs in this format:
/foo/show?id=bar

Is it possible to configure a form to direct the browser to URLs in
this format instead?:
/foo/bar

Here’s how I’m currently creating my form:

<% form_tag ‘/maps/show’, :method => :get do %>

Thanks for any suggestions!
