It doens't work, and it cannot works !
I tried this
class FormForwarding(widgets.TableForm):
fields = [
MultipleHiddenFields('context'),
widgets.CheckBox('active', label="Activate forwarding",
validator=validators.StringBool(if_empty=False)),
widgets.TextField('forward_addr', label="Address to forward
to", attrs=dict(size=40, maxlength=255), validator=EmailValidator()),
widgets.CheckBox('keep', label="Keep a copy on server",
validator=validators.StringBool(if_empty=False, if_invalid=False )),
]
submit_text = "Update forwarding"
And added some debuging into StringBool
def _to_python(self, value, state):
print "================================================="
if isinstance(value, (str, unicode)):
value = value.strip().lower()
if value in self.true_values:
return True
if not value or value in self.false_values:
return False
raise Invalid(self.message("string", state,
true=self.true_values[0],
false=self.false_values[0]),
value, state)
return bool(value)
def _from_python(self, value, state):
print "================================================="
if value:
return self.true_values[0]
else:
return self.false_values[0]
When both are checked, I can see the 4 '====' line
But when one is missing, non of them.
This is because the call (that generate the error) is done before the
call of the validator !
I thins this is because one decorator is taking the signature of the
function.
And then raise an exception because of missing argument.
Their is no solution with TG 1.x today for missing value !
It should be in red flashing in the wiki somewhere !
