Rails Using Nested Layouts http://guides.rubyonrails.org/layouts_and_rendering.html#using-nested-layouts

	<!--comment words>
	You may find that your application requires a layout that differs slightly from your regular application layout to support one particular controller. Rather than repeating the main layout and editing it, you can accomplish this by using nested layouts (sometimes called sub-templates). Here’s an example:

	Suppose you have the following ApplicationController layout:
	app/views/layouts/application.html.erb
	<-->
	<html>
	<head>
	<title><%= @page_title or 'Page Title' %></title>
	<%= stylesheet_link_tag 'layout' %>

jhjguxin / 404.html.erb

Created August 13, 2012 05:13

exception catch on rails 3(eg, 400, 403, 500), base on BBTangCMS

	<div id="error_page" class="box">
	<h1>Ops, 404</h1>
	<p>
	似乎没有这个页面哦！大哥，去看看别的吧。
	</p>
	</div>
	<!--因为不排除连rails 都无法运行的情况所以添加 'public/STATUS.htm' 还是很有必要的-->
	<!--more>
	Finally, the default exceptions application used by Rails that simply renders a page in `public/STATUS.html` is available here: [action_dispatch/middleware/public_exceptions.rb](https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/middleware/public_exceptions.rb)
	Remember that whatever you do in the errors controller, it should not be anything “fancy”. Keep it simple because something already went wrong with your application!
