NAME¶

DBIx::Class::Manual::ResultClass - Representing a single result (row) from a DB query

SYNOPSIS¶

  package My::Schema::Result::Track;
  use parent 'DBIx::Class::Core';
  __PACKAGE__->table('tracks');
  __PACKAGE__->add_columns({
    id => {
      data_type => 'int',
      is_auto_increment => 1,
    },
    cd_id => {
      data_type => 'int',
    },
    title => {
      data_type => 'varchar',
      size => 50,
    },
    rank => {
      data_type => 'int',
      is_nullable => 1,
    },
  });
  __PACKAGE__->set_primary_key('id');
  __PACKAGE__->add_unique_constraint(u_title => ['cd_id', 'title']);

DESCRIPTION¶

In DBIx::Class, a user normally receives query results as instances of a certain "Result Class", depending on the main query source. Besides being the primary "toolset" for interaction with your data, a "Result Class" also serves to establish source metadata, which is then used during initialization of your DBIx::Class::Schema instance.

Because of these multiple seemingly conflicting purposes, it is hard to aggregate the documentation of various methods available on a typical "Result Class". This document serves as a general overview of "Result Class" declaration best practices, and offers an index of the available methods (and the Components/Roles which provide them).
