=head1 SYNOPSIS
-Manual creation of a DBIx::Class::Schema and a Catalyst::Model::DBIC::Schema:
-
-=over
+=over 4
=item 1.
-Create the DBIx:Class schema in MyApp/Schema/FilmDB.pm:
+First, prepare your database schema using C<DBIx::Class>.
- package MyApp::Schema::FilmDB;
- use base qw/DBIx::Class::Schema/;
+(If you're not sure how to do this, then read L<DBIx::Class::Manual::Intro> first!)
- __PACKAGE__->load_classes(qw/Actor Role/);
+This example assumes that you already have a schema called
+C<MyApp::Schema::FilmDB>,
+which defines some tables in C<MyApp::Schema::FilmDB::Actor> and
+C<MyApp::Schema::FilmDB::Film>.
=item 2.
-Create some classes for the tables in the database, for example an
-Actor in MyApp/Schema/FilmDB/Actor.pm:
-
- package MyApp::Schema::FilmDB::Actor;
- use base qw/DBIx::Class/
-
- __PACKAGE__->load_components(qw/Core/);
- __PACKAGE__->table('actor');
-
- ...
-
-and a Role in MyApp/Schema/FilmDB/Role.pm:
+Now, to expose it to Catalyst as a model, you should create a DBIC Model in
+MyApp/Model/FilmDB.pm:
- package MyApp::Schema::FilmDB::Role;
- use base qw/DBIx::Class/
+=over 8
- __PACKAGE__->load_components(qw/Core/);
- __PACKAGE__->table('role');
+You can do this:
- ...
+=item * With the helper script
-Notice that the schema is in MyApp::Schema, not in MyApp::Model. This way it's
-usable as a standalone module and you can test/run it without Catalyst.
+ script/create.pl model FilmDB DBIC::Schema MyApp::Schema::FilmDB ...options...
-=item 3.
+See L<Catalyst::Helper::Model::DBIC::Schema> for details.
-To expose it to Catalyst as a model, you should create a DBIC Model in
-MyApp/Model/FilmDB.pm:
+=item * Manually
package MyApp::Model::FilmDB;
use base qw/Catalyst::Model::DBIC::Schema/;
=back
-Now you have a working Model which accesses your separate DBIC Schema. This can
-be used/accessed in the normal Catalyst manner, via $c->model():
+=back
- my $actor = $c->model('FilmDB::Actor')->find(1);
+Now you have a working Model which accesses your separate DBIC Schema. This can
+be used/accessed in the normal Catalyst manner, via C<< $c->model() >>:
-You can also use it to set up DBIC authentication with
-L<Catalyst::Authentication::Store::DBIx::Class> in MyApp.pm:
+ my $db_model = $c->model('FilmDB'); # a Catalyst::Model
+ my $dbic = $c->model('FilmDB')->schema; # the actual DBIC object
- package MyApp;
+The Model proxies the DBIC instance so you can do
- use Catalyst qw/... Authentication .../;
+ my $rs = $db_model->resultset('Actor'); # ... or ...
+ my $rs = $dbic ->resultset('Actor'); # same!
- ...
+There is also a shortcut, which returns a L<DBIx::Class::ResultSet> directly,
+instead of a L<Catalyst::Model>:
- __PACKAGE__->config->{authentication} =
- {
- default_realm => 'members',
- realms => {
- members => {
- credential => {
- class => 'Password',
- password_field => 'password',
- password_type => 'hashed'
- password_hash_type => 'SHA-256'
- },
- store => {
- class => 'DBIx::Class',
- user_model => 'DB::User',
- role_relation => 'roles',
- role_field => 'rolename',
- }
- }
- }
- };
+ my $rs = $c->model('FilmDB::Actor');
-C<< $c->model('Schema::Source') >> returns a L<DBIx::Class::ResultSet> for
-the source name parameter passed. To find out more about which methods can
-be called on a ResultSet, or how to add your own methods to it, please see
-the ResultSet documentation in the L<DBIx::Class> distribution.
