Hi Villas, Thanks for your reply. I tried:
is_not_in_db=IS_NOT_IN_DB(db,'hub.name',error_message='name already in
database')
db.define_table('hub',
Field(...),
Field('name',default='',requires=[IS_NOT_EMPTY(),is_not_in_db],notnull=True,unique=True),
Field(...),
migrate=False)
But I still cannot update hub. I put the validators inside the field
definition because I want to make use of lazy_tables=True
Kind regards,
Annet
