Actually, it's a very good question. All of the various CGI::App config
plugins put a config method into your $self object. But how do you get
at this data outside of your CGI::App object hierarchy?
A typical example would be configuring your Class::DBI classes from
within CGI::App. Your Class::DBI base class is expected to provide a
db_Main method returning a database handle. The problem is, this method
knows nothing about your CGI::App object:
package MyCDBI;
sub db_Main {
# get configuration from somewhere
my $conf = ???
my $dsn = $conf->{'connect_string'};
my $user = $conf->{'username'};
my $pass = $conf->{'password'};
return DBI->connect_cached($dsn, $user, $pass);
}
One way of approaching this is to store the configuration as class data
as soon as you initialize it:
package MyApp;
sub cgiapp_init {
my $self = shift;
my $config = get_config_somehow();
# store the configuration as class data
$MyProject::Current_Config = $config;
}
Then your unrelated class can fetch this data:
package MyCDBI;
sub db_Main {
# get configuration from somewhere
my $conf = $MyProject::Current_Config
or die "System not configured yet!"
my $dsn = $conf->{'connect_string'};
my $user = $conf->{'username'};
my $pass = $conf->{'password'};
return DBI->connect_cached($dsn, $user, $pass);
}
I don't know about the other CGI::Application plugins, but
C::A::P::Config::Context does this for you already. It provides a class
method for getting at configuration data:
my $config = CGI::Application::Plugin::Config::Context->get_current_context;
