NAME

DBIx::Class::Loader - Dynamic definition of DBIx::Class sub classes.

SYNOPSIS

   use DBIx::Class::Loader;
 
   my $loader = DBIx::Class::Loader->new(
     dsn                     => "dbi:mysql:dbname",
     user                    => "root",
     password                => "",
     namespace               => "Data",
     additional_classes      => [qw/DBIx::Class::Foo/],
     additional_base_classes => [qw/My::Stuff/],
     left_base_classes       => [qw/DBIx::Class::Bar/],
     constraint              => '^foo.*',
     relationships           => 1,
     options                 => { AutoCommit => 1 }, 
     inflect                 => { child => 'children' },
     debug                   => 1,
   );
   my $class = $loader->find_class('film'); # $class => Data::Film
   my $obj = $class->find(1);
 
 

use with mod_perl

in your startup.pl

   # load all tables
   use DBIx::Class::Loader;
   my $loader = DBIx::Class::Loader->new(
     dsn       => "dbi:mysql:dbname",
     user      => "root",
     password  => "",
     namespace => "Data",
   );
 
 

in your web application.

   use strict;
 
   # you can use Data::Film directly
   my $film = Data::Film->retrieve($id);
 
 

IMPORTANT NOTICE

This module is deprecated in favor of DBIx::Class::Schema::Loader for use with DBIx::Class versions 0.05 and higher. It continues to function as well as it ever did, even for recent DBIx::Class releases, and will be maintained for some time to counter bugs, but it doesn't use the now-preferred DBIx::Class::Schema way of doing things, and tends to promote bad DBIx::Class usage habits.

DESCRIPTION

DBIx::Class::Loader automate the definition of DBIx::Class sub-classes by scanning table schemas and setting up columns and primary keys.

Class names are defined by table names and the namespace option. The only required arguments are "namespace" and "dsn".

  +---------+-----------+--------------+
  | table   | namespace | class        |
  +---------+-----------+--------------+
  | foo     | Data      | Data::Foo    |
  | foo_bar | MyDB      | MyDB::FooBar |
  +---------+-----------+--------------+
 
 

DBIx::Class::Loader supports MySQL, Postgres, SQLite and DB2. See DBIx::Class::Loader::Generic for more, and DBIx::Class::Loader::Writing for notes on writing your own db-specific subclass for an unsupported db.

METHODS
