I agree with you here, even though I am not that worried about the
HTML::Template requirement in the core CGI::Application, cause I
usually have it installed anyway :)

It can still be useful if another Plugin requires database access.
When I use the C::A::P::Session module, I need to pass it a DB handle.
Ususally I just do this:
sub db {
my $self = shift;
return MyCDB::Base->db_Main(); # grab $dbh from Class::DBI
}
and then configure the session plugin as follows:
$self->session_config(
CGI_SESSION_OPTIONS => [ 'driver:PostgreSQL',
$self->query,
{ Handle =>
$self->db } ]
);
I could of course config the session stuff like this:
$self->session_config(
CGI_SESSION_OPTIONS => [ 'driver:PostgreSQL',
$self->query,
{ Handle =>
MyCDB::Base->db_Main() } ]
);
But I like the abstraction of the first method better. At some point
when I have more time, I will probably start using the DBH plugin for
this, as it standardizes things for me, even though I will probably
never directly use the dbh handle in my CGI::App modules. I am slowly
removing all the code from my custom superclass and replacing it with
plugins. This simplifies my apps, and makes them easier to maintain,
as well as less error prone (since more eyes are looking at and using
the code in the plugins).
