DBIx::Class::Loader - Dynamic definition of DBIx::Class sub classes.
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' } ); 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);
DBIx::Class::Loader automate the definition of DBIx::Class sub-classes. scan table schemas and setup columns, primary key.
class names are defined by table names and namespace option.
+-----------+-----------+-----------+ | table | namespace | class | +-----------+-----------+-----------+ | foo | Data | Data::Foo | | foo_bar | | FooBar | +-----------+-----------+-----------+
DBIx::Class::Loader supports MySQL, Postgres and SQLite.
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.
Class::DBI::Loader and Class::DBI are now obsolete, use DBIx::Class and this module instead. ;)
