NAME

DBIx::Class::UUIDColumns - Implicit uuid columns

SYNOPSIS

In your the DBIx::Class manpage table class:

  __PACKAGE__->load_components(qw/UUIDColumns ... Core/);
  __PACKAGE__->uuid_columns('artist_id');

Note: The component needs to be loaded before Core.

DESCRIPTION

This the DBIx::Class manpage component resembles the behaviour of the Class::DBI::UUID manpage, to make some columns implicitly created as uuid.

When loaded, UUIDColumns will search for a suitable uuid generation module from the following list of supported modules:

  Data::UUID
  APR::UUID*
  UUID
  Win32::Guidgen
  Win32API::GUID

If no supporting module can be found, an exception will be thrown.

*APR::UUID will not be loaded under OpenBSD due to an as yet unidentified XS issue.

If you would like to use a specific module, you can set uuid_class:

  __PACKAGE__->uuid_class('::Data::UUID');
  __PACKAGE__->uuid_class('MyUUIDGenerator');

METHODS

get_uuid

Returns a uuid string from the current uuid_maker.

insert

Inserts a new uuid string into each column in uuid_columns.

uuid_columns

Gets/sets the list of columns to be filled with uuids during insert.

  __PACKAGE__->uuid_columns('artist_id');

Takes the name of a UUIDMaker subclass to be used for uuid value generation. This can be a fully qualified class name, or a shortcut name starting with :: that matches one of the available the DBIx::Class::UUIDColumns::UUIDMaker manpage subclasses:

  __PACKAGE__->uuid_class('CustomUUIDGenerator');
  # loads CustomeUUIDGenerator

  __PACKAGE__->uuid_class('::Data::UUID');
  # loads DBIx::Class::UUIDMaker::Data::UUID;

Note that uuid_class checks to see that the specified class isa the DBIx::Class::UUIDColumns::UUIDMaker manpage subclass and throws and exception if it isn't.

uuid_maker

Returns the current UUIDMaker instance for the given module.

  my $uuid = __PACKAGE__->uuid_maker->as_string;
