NAME

Gantry::Utils::CDBI - Class::DBI base class for Gantry applications

SYNOPSIS

This module expects to retrieve the database connection, username, and password from one of two places.

In mod_perl

If it lives in mod_perl, it expects these to come from the apache conf file. You might supply them like this:

    <Location / >
	    PerlSetVar dbconn 'dbi:Pg:dbname=your_db_name'
	    PerlSetVar dbuser 'your_user'
	    PerlSetVar dbpass 'your_password'
    </Location>

It then retrieves them roughly like this (the mod_perl version affects this):

$r = Apache->request();

$r->dir_config( 'dbconn' ),  
$r->dir_config( 'dbuser' ),
$r->dir_config( 'dbpass' ),

The handle is cached using pnotes to avoid recreating it.

In scripts

On the other hand, if the module does not live in mod_perl, it needs to directly use Gantry::Utils::DBConnHelper::Script like this:

use Gantry::Utils::DBConnHelper::Script {
        dbconn => 'dbi:Pg:dbname=your_db_name',
        dbuser => 'your_user',
        dbuser => 'your_pass',
};

If you can't put the connection info into the use statement (say because you take it from the command line) do the above in two steps:

use Gantry::Utils::DBConnHelper::Script;

# figure out your connection info

Gantry::Utils::DBConnHelper::Script->set_conn_info(
        dbconn => $dsn,
        dbuser => $dbuser,
        dbuser => $dbpass,
);

The database handle is cached by the helper. To get hold of it say:

my $dbh = Gantry::Utils::DBConnHelper::Script->get_dbh();

DESCRIPTION

This module provides the base methods for Class:DBI, including the db conection method within a mod_perl environment.

METHODS

_default_attributes

Default database attributes.

Note that these other methods are mixed in from Gantry::Utils::ModelHelper:
