class ANY(object):
def __init__(self, validators):
self.validators = validators
def __call__(self, value):
# validates the value against each validator
results = [validator(value) for validator in self.validators]
# Check if there is an invalid result
for result in results:
if result[1]:
# if invalid value found returns it.
return result
#else returns the value and None, which means "valid"
return (value, None)
db.table.somefield.requires = ANY([IS_EMAIL(), IS_MATCH(), IS_NOT_EMPTY()])
it is a great idea to include ANY and ALL metavalidators to
gluon.validators.
