DISCLAIMER ^

This is ALPHA SOFTWARE. Use at your own risk. Features may change.

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).
