DBIx::C...entifier(3)

💖 DBIx::Class::Storage::DBI::UniqueIdentifier — the manual, but make it make sense 💖

okay so bestie, this one is a page from the DBIx::Class docs (perl, obviously 😌), and it's literally all about giving your database GUIDs without breaking a sweat. Let's get into it ✨

---

🎀 NAME 🎀

DBIx::Class::Storage::DBI::UniqueIdentifier — the storage component for RDBMSes that support GUID types 🫶

---

🌸 DESCRIPTION 🌸

So this is a storage component for databases that support GUID types — think stuff like uniqueidentifier, uniqueidentifierstr, or guid 💅

And here's the slay part: GUIDs get generated automatically for PK columns that have a supported data_type, and also for non-PK columns with auto_nextval set 🔥 No cap, it just does it for you.

---

⭐ METHODS ⭐

🦋 new_guid

The composing class must set new_guid to whatever method it's using to generate a new GUID. It can also set it to undef — but then the user is required to set it themselves, or a runtime error gets thrown 😭 so like, don't leave it hanging, bestie.

It can be either of these two things:

• string — in which case it's used as the name of a database function that creates a new GUID 👑
• coderef — in which case the coderef should return a string GUID, using Data::GUID, or literally whatever GUID generation method you prefer 😌 It gets passed the $self DBIx::Class::Storage reference as a parameter.

For example:

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

it's giving "one line, does the thing" 💜 obsessed.
