[cgiapp] Help with referencing cgiapp->dbh inside a plugin

[Paul Johnston <suppressed>]

Right - I have a plugin that is essentially very simple - we'll use the 
blog example from previous thread.

I have created it with one Exported method (for example blog) which 
stores the object in the calling objects private hash ie:

--- snip ---
package Plugins::Blog;
use vars qw($VERSION @EXPORT @ISA);
use strict;

require Exporter;

$VERSION = 0.01;
@ISA = qw(Exporter);
@EXPORT = qw(blog);

sub blog {
   my $app = shift;

   if(!$app->{__PACKAGE__ . '__oBlog'}) {
      # create the object for this module and store it in the app
       my $blog = {};
       bless $blog;
       $app->{__PACKAGE__ . '__oBlog'} = $blog;
   }

   return $app->{__PACKAGE__ . '__oBlog'};
}
--- snip ---

Now - the question I have is (assuming cgiapp is the calling object) how 
do I in a different method retrieve the database handle? ie

--- snip ---
sub getBlog {
   # this is the object itself, not the cgiapp
   $self = shift;
   $dbh = $self->dbh; # ??? confused!
}
--- snip ---

Help would be much appreciated.  I've tried this various ways (putting a 
reference to the app's dbh method in the object), but can't figure it 
out.  I'm going wrong somewhere and have looked at other code, but can't 
quite figure it out.

Thanks in advance.

Paul
