I've just started my first Rails 3 stable app from scratch and still
looking at all the changes. Most things are wonderful. However, I
can't figure out what happened to the layout structure.
In my controller:
class ApplicationController < ActionController::Base
And in app/views/layouts/application.html.erb:
<%= yield %>
This is the way I did it in Rails 2.3.x. I can't find what's changed
in Rails 3.0. All my actions are showing up without the layout.
