NAME

DBIx::Class::Storage::DBI::UniqueIdentifier - Storage component for RDBMSes supporting GUID types

DESCRIPTION

This is a storage component for databases that support GUID types such as "uniqueidentifier", "uniqueidentifierstr" or "guid".

GUIDs are generated automatically for PK columns with a supported data_type, as well as non-PK with auto_nextval set.

METHODS

new_guid

The composing class must set "new_guid" to the method used to generate a new GUID. It can also set it to "undef", in which case the user is required to set it, or a runtime error will be thrown. It can be:

string: In which case it is used as the name of database function to create a new GUID,
coderef: In which case the coderef should return a string GUID, using Data::GUID, or whatever GUID generation method you prefer. It is passed the $self DBIx::Class::Storage reference as a parameter.

For example:

  $schema->storage->new_guid(sub { Data::GUID->new->as_string });
