what i would like is: sub handler { my $r = shift; my $user = new Website::User( \$r ); my $page = new Website::Page( \$user ); my $html = $page->processRequest(); }
now, i guess what i'm trying to do within
Website1::User
Website1::Page
is access the
$DB in the base of Website1 that i define just before the handler
BUT
I'm trying to do so in a way that both:
Website1::PackageName
Website2::PackageName
WebAppFramework::PackageName
Will all retreive the correct DB from the script that defines the handler
Ok. This means you want to make your Website::User and Website::Page more intelligent. If I got you right the only thing have to implement
for each user is Website1::DBI and Website2::DBI.
What you really need here when talking about Pattern-Programming is a "Factory-Class" which creates the
appropiate WebAppFramework::DBI-Sub-Class for you and design all your Website*::DBI-classes as "Singletons".
===================8<=================== package WebAppFramework::DBIFactory;
sub getDb {
my $dbiModule = shift;
require($dbiModule); ## load the apprioate module
return $dbiModule->instance(); ## get an instance of the module
}1; ===================8<===================
===================8<=================== package WebAppFramework::User;
sub new {
my $class = shift;
my $r = shift;my $this =
{
db => WebAppFramework::DBIFactory::getDb($r->dir_config("DBIModule"));
};
bless $this, $class; }
1; ===================8<===================
===================8<=================== <Location /webapp1> PerlSetVar DBIModule Website1::DBI </Location>
<Location /webapp2> PerlSetVar DBIModule Website2::DBI </Location> ===================8<===================
Hope I got you right? If you don't want to use config values you could also use the name of the package
in the handler e.g. Website1, Website2 and add "::DBI" in your factory method.
