SYNOPSIS



  package MyApp::Schema::Result::Artist;

  use Moose;
  use DBIx::Class::MooseColumns;
  use namespace::autoclean;

  extends DBIx::Class::Core;

  __PACKAGE__->table(artist);

  has id => (
    isa => Int,
    is  => rw,
    add_column => {
      is_auto_increment => 1,
    },
  );

  has foo => (
    isa => Str,
    is  => rw,
    add_column => {
      data_type => datetime
    },
  );

  has bar => (        # will call __PACKAGE__->add_column({})
    isa => Str,
    is  => rw,
    add_column => {
    },
  );

  has quux => (       # no __PACKAGE__->add_column() call
    isa => Str,
    is  => rw,
  );

  __PACKAGE__->set_primary_key(id);

  __PACKAGE__->meta->make_immutable( inline_constructor => 0 );

DESCRIPTION

This module allows you to put the arguments to add_column in DBIx::Class::ResultSource right into your attribute definitions and will automatically call it when it finds an add_column attribute option. It also replaces the DBIx::Class-generated accessor methods (these are Class::Accessor::Grouped-generated accessor methods under the hood) with the Moose-generated accessor methods so that you can use more of the wonderful powers of Moose (eg. type constraints, triggers, ...).

Note: __PACKAGE__->table(...) must go <B>beforeB> the has stanzas (the table in DBIx::Class::ResultSource is magic and does much more than setting the table name, thus the __PACKAGE__->add_column(...) calls that the has triggers won’t work before that).

Note: __PACKAGE__->set_primary_key(...) and __PACKAGE__->add_unique_constraint(...) calls must go <B>afterB> the has stanzas (since they depend on the referred columns being registered via __PACKAGE__->add_column(...) and that call is done when the has runs).

TODO

o convert the test harness to something sane - consider Fennec?
o delay ->add_column() calls until right after the ->table() call (collect the args and run them in an after method modifier of ’table’, possibly batched in a single ->add_columns() call)
