Finally, I just testes on the shell
*modules/anyvalidator.py*
class ANY(object):
def __init__(self, validators):
self.validators = validators
def __call__(self, value):
# validates the value against each validator
results = [validator(value)[1] for validator in self.validators]
# check if all validations are invalid
if all(results):
# invalid, so return the first error message
return (value, [result for result in results if result][0])
else:
# all valid
return (value, None)
*models/db.py*
db.table.field.requires = ANY([IS_IN_SET(['a','b']), IS_EMAIL()])
*shell*
In [3]: from anyvalidator import ANY
In [4]: ANY([IS_IN_SET(['a','b']), IS_EMAIL()])('[email protected]')
Out[4]: ('[email protected]', None)
In [5]: ANY([IS_IN_SET(['a','b']), IS_EMAIL()])('me')
Out[5]: ('me', 'value not allowed')
In [6]: ANY([IS_IN_SET(['a','b']), IS_EMAIL()])('a')
Out[6]: ('a', None)
In [7]: ANY([IS_IN_SET(['a','b']), IS_EMAIL()])('b')
Out[7]: ('b', None)
In [8]: ANY([IS_IN_SET(['a','b']), IS_EMAIL()])('foo')
Out[8]: ('foo', 'value not allowed')
In [9]: ANY([IS_IN_SET(['a','b']), IS_EMAIL()])('[email protected]')
Out[9]: ('[email protected]', None)
