Random ids in sqlalchemy (pylons)

Question

I\'m using pylons and sqlalchemy and I was wondering how I could have some randoms ids as primary_key.

Answer 1

Or with ORM mapping:

import uuid
from sqlalchemy import Column, Integer, String, Boolean

def uuid_gen():
    return str(uuid.uuid4())

Base = declarative_base()
class Device(Base):
    id = Column(String, primary_key=True, default=uuid_gen)

This stores it as a string providing better database compatibility. However, you lose the database's ability to more optimally store and use the uuid.
