That method will hand you dirty URLs and is not PCI DSS compliant.
However, you probably want to use a chained validator to do something
like this:
class PaymentSchema(Schema):
chained_validators = [CreditCardValidator('cctype','ccnum'),
CreditCardExpires('expmon','expyear'),
CreditCardSecurityCode('cctype','cvv'),
RunCharge
('cctype','ccnum','expmon','expyear','cvv','addr1']
class PaymentForm(TableForm):
action = 'makepayment'
submit_text = 'make my payment'
validator = PaymentSchema
Then write your own validator for RunCharge:
class RunCharge(FancyValidator):
def _to_python(self, value, state):
# do magic
if card.declined:
flash(_('card declined'))
raise Invalid(
_('sorry, your card was declined'),
value, state)
return value
If you are using 2.0.1, you might take a look at
