The database consists of the following:
table 'artist' with columns: artistid, name
- table 'cd' with columns: cdid, artist, title
+ table 'cd' with columns: cdid, artist, title, year
table 'track' with columns: trackid, cd, title
use base qw/DBIx::Class::Core/;
__PACKAGE__->load_components(qw/InflateColumn::DateTime/);
__PACKAGE__->table('cd');
- __PACKAGE__->add_columns(qw/ cdid artist title/);
+ __PACKAGE__->add_columns(qw/ cdid artist title year/);
__PACKAGE__->set_primary_key('cdid');
__PACKAGE__->belongs_to('artist' => 'MyApp::Schema::Result::Artist');
__PACKAGE__->has_many('tracks' => 'MyApp::Schema::Result::Track');
A reference implementation of the database and scripts in this example
are available in the main distribution for DBIx::Class under the
-directory F<t/examples/Schema>.
+directory F<examples/Schema>.
With these scripts we're relying on @INC looking in the current
working directory. You may want to add the MyApp namespaces to
model.
This example uses L<DBIx::Class::Schema/load_namespaces> to load in the
-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).
+appropriate L<Result|DBIx::Class::Manual::ResultClass> classes from the
+C<MyApp::Schema::Result> namespace, and any required
+L<ResultSet|DBIx::Class::ResultSet> classes from the
+C<MyApp::Schema::ResultSet> namespace (although we created the directory
+in the directions above we did not add, or need to add, any resultset
+classes).

Inspect the database:
- DBIx-Class/examples/Schema$ echo .dump | sqlite3 db/example.db
+ DBIx-Class/examples/Schema$ sqlite3 db/example.db .dump
You can also use a GUI database browser such as
L<SQLite Manager|https://addons.mozilla.org/firefox/addon/sqlite-manager>.
interacting with the database through DBIC and the C<Result> classes correspond
to the tables in the database. L<DBIx::Class::Manual::Example> shows how to
write all that Perl code. That is almost never necessary, though. Instead use
-L<dbicdump> (part of the distribution C<DBIx-Class-Schema-Loader>) to
+L<dbicdump> (part of the distribution L<DBIx::Class::Schema::Loader>) to
automatically create schema classes files from an existing database. The
chapter L</"Resetting the database"> below shows an example invocation.
