I believe so, but I've only played around a little with validators. The other suggestions may be simpler for you. Or you can search for custom validators among the old posts, and check the web2py book <URL:http://www.web2py.com/books/default/chapter/29/07/forms-and-validators#Custom-validators> In my db.py, I have (at the end) this terribly unsophisticated custom validator. from gluon.validators import Validator class IS_HEXSTR(Validator): def __init__(self, format='%c%c%c%c', error_message='must be a 4-digit hex string like A09F!'): self.format = format self.error_message = error_message def __call__(self, value): try: if len(value) != 4: raise ValueError intvalue = int(value, 16) print "should be valid " + str(intvalue) return (value, None) except ValueError: print "invalid " + value return (value, self.error_message) except Exception as e: print "invalid " + value raise e def formatter(self, value): return value.upper() -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
