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

the best way is to use randomly generated UUIDs:

import uuid

id = uuid.uuid4()

uuid datatypes are available natively in some databases such as Postgresql (SQLAlchemy has a native PG uuid datatype for this purpose - in 0.5 its called sqlalchemy.databases.postgres.PGUuid). You should also be able to store a uuid in any 16 byte CHAR field (though I haven't tried this specifically on MySQL or others).
