Rails - Apr 2007 - What does this mean?

Holds the template files for layouts to be used with views. This
models the common
  header/footer method of wrapping views. In your views, define a
layout using the
  <tt>layout :default</tt> and create a file named default.rhtml.
Inside default.rhtml,
  call <% yield %> to render the view using this layout.

This text is from official readme. I do not know where to write
"layout :default", and where to put default.rhtml file....
I used to put "layout :default" in application.rb, so all page use
this layout, but now, it does not work....

Thanks.

Create: app/views/layouts/default.rhtml...

Then in app/controllers/application.rb put b/n the class...end block.

 	layout ''default''

However you only need to do that if you want your layout to be called 
"default" for some reason. If you call your layout rhtml file 
application.rhtml, then that layout will be used automatically... no 
need to specify it in application.rb.

If you need different layouts for different parts of your app, you can 
make additional layout files and using the "layout
''layoutname''" call in
the appropriate controller... or name the layout file the same name as 
your controller (as scaffolding does) and it will get used automatically 
for calls to that controller.

application.rhtml file, and it does not work as a default layout....

Hmm, works for me... Are you sure you haven''t set a "layout
''something''"
in the controller you''re calling?

You can specify the layout in your controller. If you want to have a
default layout, it''s best to name it "application.rhtml" (or
.rxml, or
whichever). Rails will use that as the default for any controller that
doesn''t have its own layout. Layouts go in
"your_application/app/views/
layouts" by convention, and Rails will look for them there.

So, how does a controller get its own layout? Two ways. The most
common is simply by naming a layout after the controller. For example,
if you have a controller called "FooController", then Rails will look
for a layout called "foo.rhtml" (or .rxml, or whichever) first.

The second way is to explicitly name the layout you want applied to
the views of a controller within the controller itself (this is where
"layout :default" comes in). Say you want FooController to have the
"bar" layout instead:

class FooController < ApplicationController
   layout "bar"
   . . .
end

Layouts are inherited, so if FoobarController extends FooController,
it will also get the "bar" layout unless you specify otherwise.
Finally, the "layout" declaration can actually take arguments beyond
just strings, so you can conditionally apply layouts and do all sorts
of other craziness if that sort of thing turns you on.

I am trying to use an inherited hook:

module StarMonkey
   class MyStarMonkey
      def self.inherited(klass)
         puts klass.const_defined(''LIKES_CRUNCHY_BACON'')
      end
   end
end

My personal star monkey

class FredrickTheGreat < StarMonkey::MyStarMonkey
   LIKES_CRUNCHY_BACON = ''hello world!''
end

now for IRB goodness:

 >> puts
FredrickTheGreat.const_defined?(''LIKES_CRUNCY_BACON'')
=> true
=> true

seems to work. now for something more real life

The hook

module ActiveRecord
   class Base
      def slef.inherited(klass)
         puts klass.has_const(''LIKES_CRUNCHY_BACON'')
      end
   end
end

Model

class StarMonkey < ActiveRecord::Base
   LIKES_CRUNCHY_BACON = true
end

script/console ---

 >> puts
StarMonkey.const_defined?(''LIKES_CRUNCHY_BACON'')
=>false #this is my inherited hook
=>true


What gives?
