You are doing something wrong here...
Model Class Modules should be as easy as this (note that i'm using the
svn version):
# BeerDB.pm
package BeerDB;
use base qw(Maypole::Application Maypole::Loader);
BeerDB->setup(lalala...);
BeerDB->load_model_classes;
lalala...
# BeerDB/Beer.pm
package BeerDB::Beer;
sub top_five : Exported {
lalala...
}
lalala...

> Yes, but less lines option please. For example, four-lines:

> package BeerDB;
> use base 'Apache::MVC::MORESIMPLE';
> BeerDB->setup("dbi:SQLite:t/beerdb.db");
> 1;

> All the configurations

> rows_per_page

> untaint_columns
> display_tables
> display_columns (for each table)
> column_names (for each table)
> should be stored in 'beerdb.db' itself or other external configuration
> file(YML?).

Please file bugs against the svn version...
You can grab bleeding edge versions of everything (and some unreleased
helper modules) from http://oook.de
