OK, here is one way:
def radio_msg():
opts=['english', 'french', 'german']
form=SQLFORM.factory(
Field('language', 'string',
requires = IS_IN_SET(opts),
widget = SQLFORM.widgets.radio.widget
)
)
if form.accepts(request):
response.flash='ok'
elif form.errors:
# turn off error msg for all but last radio field
for opt in opts[:-1]:
form.element('input[type=radio][value=%s]'%opt)
['hideerror']=True
response.flash='not ok'
return dict(form=form)
