NAME
Class::DBI::Lite - Lightweight ORM for Perl
SYNOPSIS
Create some database tables:
create table artists (
artist_id integer primary key autoincrement,
artist_name varchar(100) not null
);
create table cds (
cd_id integer primary key autoincrement,
artist_id integer not null,
cd_name varchar(100) not null
);
package My::Model;
use base 'Class::DBI::Lite::mysql'; # Or ::SQLite, etc
__PACKAGE__->connection( 'DBI:mysql:dbname:localhost', 'user', 'pass' );
1;# return true:
package My::Artist;
use base 'My::Model';
__PACKAGE__->set_up_table('artists');
__PACKAGE__->has_many(
cds =>
'My::CD' =>
'artist_id'
);
1;# return true:
package My::CD;
use base 'My::Model';
__PACKAGE__->set_up_table('cds');
__PACKAGE__->has_a(
artist =>
'My::Artist' =>
'artist_id'
);
1;# return true:
Then, in your script someplace:
use My::Artist;
my $artist = My::Artist->retrieve( 123 );
foreach my $cd ( $artist->cds )
{
...
}# end foreach()
my $cd = $artist->add_to_cds( cd_name => "Attak" );
print $cd->cd_name;
$cd->cd_name("New Name");
$cd->update();
# Delete the artist and all of its CDs:
$artist->delete;
DESCRIPTION
Sometimes Class::DBI is too crufty, and DBIx::Class is too much.
Enter Class::DBI::Lite.
