Overview

Layout

A Layout just behaves as a normal widget plus it will give you the @content_for_layout instance variable with the content generated from the controller.

Naming

Name it FilenameLayout (ending always with Layout, for example: ‘StandardLayout’ or ‘FancyLayout’). When you specify your layout in the controller simply do a

layout 'standard'

Examples

Layout Class:

class PlainLayout < Cuca::Layout

 def output
   content << "     <html>\n       <head><title>\#{@page_title}</title></head>\n     <body>\n      \#{@content_for_layout}\n     <hr>\n     <small>Rendered using the Plain Layout - at \#{Time.new.to_s}</small>\n     </body>\n     </html>\n     EOI\n end\nend\n"

Example Controller that would work with the above layout:

class IndexController < Cuca::Controller
 layout 'plain'

 def run
    @page_title = "Main Page"
    content << "<h3>Welcome to my Webpage</h3>
 end
end

Note: The above example doesn’t make use of a generator - which would simplify the development of larger layouts and controllers.
