Using the buddy demo as an example, with the following interface:
"""Provides access to basic buddy information"""
fullname = TextLine(title=_("Name"))
email = TextLine(title=_("Email Address"))
phone = TextLine(title=_("Phone Contact"))
How do I implement a validation rule that says either email or phone
have to exist, but not necissarily both.
I was hoping that I could add another zope.schema.Field which would
hold the validation rule, but I cant see how.
Any help would be appreciated.
Thanks and Regards,
