I use the following, which allows me to use a base class that is defined in a config file - Class::DBI has subclasses for MySQL, pgsql, and others, so I found this to be handy.
use Mayhem::Config qw/get_config/;
my $base_class_name;
BEGIN {
my $config = get_config();
$base_class_name = $config->perl_object_base_class;
eval "use base '$base_class_name'";
eval sprintf("__PACKAGE__->set_db('Main', %s);", $config->db_conn
+ect_string);
}
}
1;
where $config->perl_object_base_class returns items of the form 'Class::DBI::SQLite' and $config->db_connect_string returns something like '"DBI:sqlite:dbname", "username", "password"'
This allows me to run my system against SQLite or mysql or postgres with just changing the config file (and having the databases setup correctly of course ;)
