DBIx::Class::UUIDColumns(3)

NAME
DBIx::Class::UUIDColumns - Implicit uuid columns

SYNOPSIS
In your DBIx::Class table class:

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

Note: The component needs to be loaded before Core.

DESCRIPTION
This DBIx::Class component resembles the behaviour of Class::DBI::UUID, 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');

  uuid_class
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 DBIx::Class::UUIDColumns::UUIDMaker 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 DBIx::Class::UUIDColumns::UUIDMaker 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;
