+<div class="para"><p>By default, when you use <tt>map.resources</tt> to create a route, Rails generates routes for seven default actions (index, show, create, new, edit, update, and destroy). But each of these routes takes up memory in your application, and causes Rails to generate additional routing logic. Now you can use the <tt>:only</tt> and <tt>:except</tt> options to fine-tune the routes that Rails will generate for resources. You can supply a single action, an array of actions, or the special <tt>:all</tt> or <tt>:none</tt> options. These options are inherited by nested resources.</p></div>
