path from db as string not evaluated

Hey,

my menu is stored in the database like that:
name path
Home root_path
Users users_path

and I create the links with link_to_remote:
<%= link_to_remote navigation.name,
  :url => navigation.target,
  :update => 'contentBody',
  :method => :get %>

The problem is when I load page it looks like:
<a onclick="new Ajax.Updater('contentBody', 'users_path',
{asynchronous:true, evalScripts:true, method:'get'}); return false;"
href="#">Users</a>

Does anyone know how to evaluate that users_path so it's /users instead?
