We use UUIDs for database sync.
If we just include as a default=uuid.uuid4() then this doesn't work
when creating multiple records in the same transaction (as they all
have identical UUIDs)
We therefore created our own custom function as follows:
# Reusable UUID field (needed as part of database synchronization)
import uuid
from gluon.sql import SQLCustomType
s3uuid = SQLCustomType(
type ='string',
native ='string',
encoder = (lambda x: "'%s'" % (uuid.uuid4() if x==""
else x)),
decoder = (lambda x: x)
)
uuidstamp = db.Table(None, 'uuidstamp',
Field('uuid',
type=s3uuid,
length=64,
notnull=True,
unique=True,
readable=False,
writable=False,
default=""))
This was working fine up through 1.71.1.
Something since has broken it (I have reverted but good to get this
fixed before the next stable release)
Many thanks,
Fran.
