you can create your on validators:
class IS_DIR:
def __init__(self,error_message='Dir does not exist'):
self.error_message=error_mesage
def __call__(self,value):
import os
if not or.path.isdir(value): return
(value,self.error_message)
return (value,None)
db.table.field.requires=[IS_NOT_EMPTY(),IS_DIR()]
I smell directry traversal attack here. Depends on the contexts.
