in thread CGI::Application, inheritance trees, and 'the right way'

$this was a typo; should have been $self.

In the example, SiteManager isn't dispatching sub-requests; I should have used different names than those you'd given. I was considering the modules that SiteManager might load being not additional CGI::Application modules or modules that create output but API level things -- grabbing events for a calendar that needs to be displayed on every page, or a site navigation that needs to be custom generated on each page.

You can still have a single page that your client can bookmark, but this might be more of a homepage with links to other applications. The applications would all inherit from SiteManager so that you get:

  • Centralized authentication
  • Centralized navigation
  • Sitewide template shell
  • etc.

Another possibility would be to have an application that would dynamically instantiate and run() other CGI::Applications:

package SiteManager; use base qw/CGI::Application/; use EventManager; use EmailManager; sub setup { $self = shift; $self->run_modes( 'events' => 'events', 'email' => 'email ); } sub events { $self = shift; # Initialize a params hash or grab it from a config file and t +hen... $events = new EventManager($params); $events->run(); } sub email { $self = shift; # Initialize a params hash or grab it from a config file and t +hen... $email = new EmailManager($params); $email->run(); }

However, even with this example, it might not be a bad idea to have a base class that takes care of authentication, site template, etc.
