Me too. With a str() around it…

I've been using Python's uuid.uuid4() function.  It works fine for generating a random uuid for a new record you're creating in a FOLIO module.

Hi Zeno,

For Python, I would start here:

Hi Zeno,

reminds me of https://issues.folio.org/browse/RMB-347 .

In Java, UUID is generated like this:

( cf. https://github.com/folio-org/raml-module-builder/blob/v23.11.0/domain-models-runtime/src/main/java/org/folio/rest/persist/PgUtil.java#L305)

String idString = UUID.randomUUID().toString();

where Class UUID is imported from here:

import java.util.UUID;

Don't know what this translates to in Python

Ciao

Hi to all,

to import data into Folio using FolioConsoleApplication

[https://github.com/jemiller0/Folio] I need to prepare the correct .json

files.

For me it is not clear how to insert a correct value into 'uuid' columns.

How can I calculate uuid values ?

I see that in

https://github.com/jemiller0/folio-migration/blob/master/lehigh_scripts/ole_assign_uuids_batch.py

the relevant python code is:

import MySQLdb

import uuid

from datetime import datetime

...

def process_bib(db, bib_row):

    bib_uuid = uuid.uuid4()

In uuid library doc page

[https://docs.python.org/2.7/library/uuid.html]

I see:

This module provides immutable UUID objects (the UUID class) and the

functions uuid1(), uuid3(), uuid4(), uuid5() for generating version 1,

3, 4, and 5 UUIDs as specified in RFC 4122.

If all you want is a unique ID, you should probably call uuid1() or

uuid4(). Note that uuid1() may compromise privacy since it creates a

UUID containing the computer’s network address. uuid4() creates a random

UUID.

...

uuid.uuid4()

     Generate a random UUID.

So, do we create UUID in FOLIO with 'uuid.uuid4' or similar functions in

others languages?

Cheers
