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',

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 before 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 after 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

convert the test harness to something sane - consider Fennec?
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)
