title: Pass Parameters in Link_to
body: <p>I would like to pass a parameter through a <code>link_to</code> method in Rails. I know there is a way to do it via the URL but I really don't want to do that. Is there any way to pass a param via a link without adding it to the link itself?</p>
  
  <p>I know in PHP you can post and then retrieve that value by using the post variable. Is there something similar in Rails?</p>
