The table in question has a field:
Field('Paiddate', 'date', requires = [IS_EMPTY_OR(IS_DATE()),
IS_EMPTY_OR(IS_MEMBERSHIP_YEAR_END())]),
The custom validator is:
class IS_MEMBERSHIP_YEAR_END(object):
def __init__(self, error_message='Not a membership year end'):
self.error_message = error_message
def __call__(self, value):
yearend = datetime.date(2018,9,30)
if value.month==yearend.month and value.day==yearend.day:
return (value, None)
return (value, self.error_message)
This works in 2.17.2
I updated my test environment to 2.18.4 and it fails.
On the console I see:
