I'm new to rails and am trying to work out how to get nested layouts working; I'm assuming they're a bit like .net master pages?
I've followed this guide and I've created an application.erb.html in my layout directory which contains this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="content-type" content="text/html;charset=UTF-8" />
<title><%= @page_title or 'Page Title' %></title>
<%= stylesheet_link_tag 'layout' %>
<style type="text/css"><%= yield :stylesheets %></style>
</head>
<body>
<%= yield(:content) or yield %>
</body>
</html>
and have modified one of my existing layouts to this:
<% content_for :stylesheets do %>
<% end -%>
<% content_for :content do %>
<p style="color: green"><%= flash[:notice] %></p>
<%= yield %>
<% end -%>
<% render :file => 'layouts/application' %>
When I go to one of my views in the browser, absolutely nothing is rendered; when I view source there is no html.
I'm sure there's something elementary I've missed out, can anyone point it out please?!

Nesting layouts is actually quite easy. It uses the content_for method to declare content for a particular named block, and then render the layout that you wish to use. So, that's the normal application layout.
A layout defines the surroundings of an HTML page. It's the place to define a common look and feel of your final output. Layout files reside in app/views/layouts. The process involves defining a layout template and then letting the controller know that it exists and to use it.
By default, if you use the :plain option, the text is rendered without using the current layout. If you want Rails to put the text into the current layout, you need to add the layout: true option and use the . text. erb extension for the layout file.
I've worked out the solution, although it's not what's given in this article
I've replaced this line
<% render :file => 'layouts/application' %>
with
<%= render :file => 'layouts/application' %>
I'm not sure if the article is wrong, or I've found the wrong way to fix it! Please let me know!
Cheers
