NAME

Class::DBI::Plugin::Connection - apply for Apache::DBI in mod_perl environment

SYNOPSIS

  package CD;
  use base qw(Class::DBI);

  use Class::DBI::Plugin::Connection;
  # then connection type is automatically selected.
  # use DBI::connect instead of DBI::connect_chached
  # in mod_perl environment.

  # or you can force to set.
  __PACKAGE__->connection_caching(1);

  # now CDBI connects to database with selected proper method.
  __PACKAGE__->set_db(...);

DESCRIPTION

This module handles CDBI app's connection type.

CDBI makes connection with DBI::connect_cached to decrease connection costs. This is better most of the time.

But when you want to use CDBI in mod_perl environment, Maybe you want to use Apache::DBI for persistent connection. Apache::DBI doesn't support connect_cached.

As the solution for this problem, you can use this module.

PROPERTY

connection_caching

All you have to do is to write 'use Class::DBI::Plugin::Connection;', and proper connection method will be selected automatically. But if there are times when you want to choose connection type yourself, set this property.

  __PACKAGE__->connection_caching(0); # connect with DBI->connect(...)

  __PACKAGE__->connection_caching(1); # connect with DBI->connect_cached(...)
