NAME

Bio::Chado::Schema

SYNOPSIS

  use Bio::Chado::Schema;

  my $chado = Bio::Chado::Schema->connect( $dsn, $user, $password );

  print "number of rows in feature table: ",
        $chado->resultset('Sequence::Feature')->count,
        "\n";

DESCRIPTION

This is a standard object-relational mapping layer for use with the GMOD Chado database schema. This layer is implemented with DBIx::Class, generated with the help of the very fine DBIx::Class::Schema::Loader module.

Chado is an open-source modular database schema for biological data. It is divided into several notional "modules", which are reflected in the namespace organization of this package. Note that modules in the Chado context refers to sets of tables, they are not modules in the Perl sense.

To learn how to use this DBIx::Class ORM layer, a good starting point is the DBIx::Class::Manual.

CLASS METHODS

plugin_add_relationship( 'ChadoModule::SourceName', 'reltype', @args )

Sometimes application-specific plugins need to add relationships to the core BCS classes. It can't just be done normally from inside the classes of the plugins, you need to use this method.

Example: Bio::Chado::Schema::Result::MyApp::SpecialThing belongs_to the core BCS Organism::Organism, and you would like to be able to call $organism->myapp_specialthings on organisms to get their associated SpecialThings.

    package Bio::Chado::Schema::MyApp::Result::SpecialThing;

    # ( do table and column definitions and so forth here )

    Bio::Chado::Schema->plugin_add_relationship(
        'Organism::Organism', 'has_many', (
            "myapp_specialthings",
            "Bio::Chado::Schema::MyApp::Result::Foo",
            { "foreign.organism_id" => "self.organism_id" },
            { cascade_copy => 0, cascade_delete => 0 },
        );
    );
