Now create some more directories:
- mkdir MyDatabase
- mkdir MyDatabase/Main
- mkdir MyDatabase/Main/Result
- mkdir MyDatabase/Main/ResultSet
+ mkdir MyApp
+ mkdir MyApp/Schema
+ mkdir MyApp/Schema/Result
+ mkdir MyApp/Schema/ResultSet
Then, create the following DBIx::Class::Schema classes:
-MyDatabase/Main.pm:
+MyApp/Schema.pm:
- package MyDatabase::Main;
+ package MyApp::Schema;
use base qw/DBIx::Class::Schema/;
__PACKAGE__->load_namespaces;
1;
-MyDatabase/Main/Result/Artist.pm:
+MyApp/Schema/Result/Artist.pm:
- package MyDatabase::Main::Result::Artist;
+ package MyApp::Schema::Result::Artist;
use base qw/DBIx::Class::Core/;
__PACKAGE__->table('artist');
__PACKAGE__->add_columns(qw/ artistid name /);
__PACKAGE__->set_primary_key('artistid');
- __PACKAGE__->has_many('cds' => 'MyDatabase::Main::Result::Cd');
+ __PACKAGE__->has_many('cds' => 'MyApp::Schema::Result::Cd');
1;
-MyDatabase/Main/Result/Cd.pm:
+MyApp/Schema/Result/Cd.pm:
- package MyDatabase::Main::Result::Cd;
+ package MyApp::Schema::Result::Cd;
use base qw/DBIx::Class::Core/;
__PACKAGE__->load_components(qw/InflateColumn::DateTime/);
__PACKAGE__->table('cd');
__PACKAGE__->add_columns(qw/ cdid artist title/);
__PACKAGE__->set_primary_key('cdid');
- __PACKAGE__->belongs_to('artist' => 'MyDatabase::Main::Result::Artist');
- __PACKAGE__->has_many('tracks' => 'MyDatabase::Main::Result::Track');
+ __PACKAGE__->belongs_to('artist' => 'MyApp::Schema::Result::Artist');
+ __PACKAGE__->has_many('tracks' => 'MyApp::Schema::Result::Track');
1;
-MyDatabase/Main/Result/Track.pm:
+MyApp/Schema/Result/Track.pm:
- package MyDatabase::Main::Result::Track;
+ package MyApp::Schema::Result::Track;
use base qw/DBIx::Class::Core/;
__PACKAGE__->table('track');
__PACKAGE__->add_columns(qw/ trackid cd title /);
__PACKAGE__->set_primary_key('trackid');
- __PACKAGE__->belongs_to('cd' => 'MyDatabase::Main::Result::Cd');
+ __PACKAGE__->belongs_to('cd' => 'MyApp::Schema::Result::Cd');

directory F<t/examples/Schema>.
With these scripts we're relying on @INC looking in the current
-working directory. You may want to add the MyDatabase namespaces to
+working directory. You may want to add the MyApp namespaces to
@INC in a different way when it comes to deployment.
The F<testdb.pl> script is an excellent start for testing your database
model.
This example uses L<DBIx::Class::Schema/load_namespaces> to load in the
-appropriate L<Row|DBIx::Class::Row> classes from the MyDatabase::Main::Result namespace,
-and any required resultset classes from the MyDatabase::Main::ResultSet
+appropriate L<Row|DBIx::Class::Row> classes from the MyApp::Schema::Result namespace,
+and any required resultset classes from the MyApp::Schema::ResultSet
namespace (although we created the directory in the directions above we
did not add, or need to add, any resultset classes).
