Here's what I came up with ...
def clean(self):
"""
Do some special validation on biz_state and biz_zip fields so
either it
or international fields are defined.
"""
try:
if self.cleaned_data['biz_state']:
# just make sure it's not empty string
pass
else:
try:
if self.cleaned_data['biz_state_intl']:
# just make sure it's not empty string
pass
else:
# if we got this far that means the two fields
#validated (are clean) but empty. set the
errors.
self._errors['biz_state'] = [
u'Please define a US State or
International State.'
]
self._errors['biz_state_intl'] = [
u'Please define a US State or International
State.'
]
except KeyError:
# biz_state_intl wasn't clean. let the parent
class do its
# thing.
pass
except KeyError:
# biz_state wasn't clean. let the parent class do its
thing.
pass
try:
if self.cleaned_data['biz_zip']:
# just make sure it's not empty string
pass
else:
try:
if self.cleaned_data['biz_zip_intl']:
# just make sure it's not empty string
pass
else:
# if we got this far that means the two fields
#validated (are clean) but empty. set the
errors.
self._errors['biz_zip'] = [
u'Please define a US State or
International Zipcode.'
]
self._errors['biz_zip_intl'] = [
u'Please define a US State or
International Zipcode.'
]
except KeyError:
# biz_zip_intl wasn't clean. let the parent class
do its
# thing at the bottom.
pass
except KeyError:
# biz_zip wasn't clean. let the parent class do its thing.
pass
return super(AppFormPart1, self).clean()
