I think I may be going about this wrong, but I want to throw new form
errors if something happens after doing form.accepts(...). I'm not using
SQLFORM or CRUD, just the FORM().
The scenario is something like this: The user enters payment information
correctly, but when I charge the card, the card is returned declined. Then,
the form should display an error saying that there are errors with the card
and present the user with the form again, as though validation had failed.
The same flow would go with emailing the user too.
form = FORM(...)
if form.accepts(request, session):
try:
makePayment(....)
redirect(URL('successful_payment')) # Redirect after success
except ...
# Display Errors on form here and show the form to the user.
elif form.errors: # Validation has failed
response.flash = 'form has errors'
What would go in the except block?
