Johann, Manuele and Massimo, Thanks for answering my question.
You're right, the problem was somewhere else, in the line before
db.Node.createdOn.represent
db.Node.createdOn.requires=IS_DATETIME(str(T('%Y-%m-%d %H:%M:%S')))
This saves without problem:
db.Node.createdOn.requires=IS_DATETIME(format='%Y-%m-%d %H:%M:%S')
db.Node.createdOn.represent = lambda v, row: v.strftime('%d/%m/%Y')
I don't know what's wrong with the first IS_DATETIME() validator.
Kind regards,
Annet
