Using Google Source Code search, I finally managed to find a few
examples to help me figure out how to do this correctly.
The solution I came up with is as follows, please let me know if there
is a better way:
# FancyValidator to process the Credit Card using the authorize
package
class ProcessCard(validators.FancyValidator):
def _to_python(self, value, state):
# --snip authorize package stuff--
result_dict = aim.transaction(
# --snip--
)
if result_dict['code'] == '1':
# success
return value
else:
# failure
raise validators.Invalid(
result_dict['reason_text'],
value, state)
class AuthnetForm(TableForm):
submit_text='Purchase'
validator = validators.Schema(
chained_validators = [
validators.CreditCardValidator('ccType','ccNumber'),
validators.CreditCardSecurityCode('ccType','ccCode'),
ProcessCard()
]
)
children=[
TextField('name', validator=validators.String
(not_empty=True)),
# --snip--
Spacer(),
SingleSelectField('ccType', options=[('visa', 'Visa'),
('mastercard', 'Master Card'), ('discover', 'Discover'), ('amex',
'American Express')], validator=validators.NotEmpty),
CalendarDatePicker('ccExpires', date_format="%m/%Y",
validator=validators.NotEmpty),
TextField('ccNumber', label_text='Card #',
validator=validators.NotEmpty),
TextField('ccCode', label_text='CVV Code',
validator=validators.NotEmpty),
Spacer()
]
authnet_form = AuthnetForm('authnet_form')
class AuthnetController(BaseController):
@expose('vynetwork.templates.authnet.index')
def index(self, **kw):
if getattr(tmpl_context, 'form_errors', None):
if tmpl_context.form_errors.get('_the_form', None):
flash(tmpl_context.form_errors['_the_form'], 'error')
return dict(page='home', kw=kw, form=authnet_form)
@validate(authnet_form, error_handler=index)
@expose()
def process(self, **kw):
return 'Thank you!'
