I'm trying to figure out how to create an 'optional' field -
specifically an optional email address.
What I've had to do is:
TableForm(widgets=[TextField(name='email',
validator=validators.Any(validators.Empty(), validators.Email()))])
(ValidateAny seems to be referenced in a docstring, but it's actually
formencode.compound.Any, which is in turbogears.validators.Any)
Someone pointed me at the not_empty=False kwarg, but the Email validator
seems to ignore it - each to_python should inspect and deal with it.. -
but this seems like a misdesign anyway - why should the subclass have to
reimplement the 'not_empty' semantic?
Is there a bug tracker for formencode? I couldn't find it, and no one on
irc knew about it.
