Hi,
I think these validators would be a nice addition to the great set of
validators we already have. They can be useful for fields for names
and phone numbers.
class IS_LETTERS(Validator):
"""
Checks if field's value consists of all letters
example::
INPUT(_type='text', _name='name', requires=IS_LETTERS())
>>> IS_LETTERS()("A")
('A', None)
>>> IS_LETTERS()("")
('', None)
>>> IS_LETTERS()("A_")
('A_', 'enter only letters')
>>> IS_LETTERS()("!")
('!', 'enter only letters')
"""
def __init__(self, error_message='enter only letters'):
IS_MATCH.__init__(self, '^[A-Za-z]*$', error_message)
class IS_DIGITS(Validator):
"""
Checks if field's value consists of all numeric digits
example::
INPUT(_type='text', _name='name', requires=IS_DIGITS())
>>> IS_NUMBERS()("1")
('1', None)
>>> IS_NUMBERS()("")
('', None)
>>> IS_NUMBERS()("A")
('A', 'enter only numbers')
>>> IS_NUMBERS()("!")
('!', 'enter only numbers')
"""
def __init__(self, error_message='enter only digits'):
IS_MATCH.__init__(self, '^[0-9]*$', error_message)
