Please help me to understand how to use uuid.
db.define_table('x',
Field('uuid', length=64, default=uuid.uuid4(), notnull=True,
writable=False, unique=True, ondelete='CASCADE'),
Field('a'),
Field('b'))
In [4]: db.x[0] = dict(a='a', b= 'b')
In [5]: db.commit()
In [6]: db.x[0] = dict(a='d', b= 'c')
---------------------------------------------------------------------------

some traceback code
...
IntegrityError: duplicate key value violates unique constraint "x_uuid_key"
How did I use uiid wrongly? I thought it was supposed to be a unique field.

Johann
