I've had similar issues in the past that I dealt with like this, not
sure if this is what you're looking for or not.
import formencode as fe
class IdValidator(fe.FancyValidator):
def _to_python(self, value, state):
ret = {'id':[]}
for v in value:
try:
ret['id'].append(int(v))
except (ValueError, TypeError):
raise fe.Invalid('id must be integer',
value, state)
return ret
class InputFormSchema(fe.Schema):
allow_extra_fields = True
filter_extra_fields = True
id = IdValidator()
