First I had it like the way you say, but then changed it, because it hat
not been working.
Looks like if validators.Int() itself is working
>>> from formencode import validators
>>> i = validators.Int()
>>> i.to_python(3)
3
>>> i.to_python('as')
Traceback (most recent call last):
File
"/home/user/tg2env/lib/python3.2/site-packages/formencode/validators.py",
line 957, in _convert_to_python
return int(value)
ValueError: invalid literal for int() with base 10: 'as'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/user/tg2env/lib/python3.2/site-packages/formencode/api.py",
line 476, in to_python
value = tp(value, state)
File
"/home/user/tg2env/lib/python3.2/site-packages/formencode/validators.py",
line 959, in _convert_to_python
raise Invalid(self.message('integer', state), value, state)
formencode.api.Invalid: Bitte eine ganze Zahl eingeben
So I created an FakeValidator, just to take a look if he is called anyhow:
class FakeValidator(formencode.Validator):
def to_python(self, value, state=None):
print("\n\nabout to get hit...\n\n")
raise TGValidationError('you hit me')
But he is not fired at any time. So somehow
So the validation is not done at all.
But
str(tg.request.validation['values'])
prints out all the values entered into the form.
So at the moment I got no clue, how to tell TG2 to do validation with those
parameters...
