The web2py book needs to be updated, as Anthony points out.
As suggested I changed the validator to:
class IS_MEMBERSHIP_YEAR_END(Validator):
def __init__(self, error_message='Not a membership year end'):
self.error_message = error_message
def validate(self, value):
yearend = datetime.date(2018,9,30)
if value.month==yearend.month and value.day==yearend.day:
return value
else:
raise ValidationError(self.translator(self.error_message))
Also added to the model:
from gluon.validators import Validator
If the entered value was a valid date that passed the test (9/30/nnnn) all
was well. However the failure path produced a ticket, it looks as if the
raised error is not being caught????
