I tried this in a controller and worked fine:
def factory():
options = ['a','b','c']
form = SQLFORM.factory(Field('Optimizers',
requires=IS_IN_SET(options,multiple='multiple')))
if form.accepts(request.vars, session):
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
return dict(form = form, form_options = form.vars.Optimizers)
Note that according to the web2py book: "The elements of the set must
always be strings unless this validator is preceded by IS_INT_IN_RANGE
(which converts the value to int) or IS_FLOAT_IN_RANGE (which converts
the value to float)"
I have also 2 questions though if somebody can help:
1. If nothing is selected why the form is accepted?
2. If I try to use multiple validators in requires=[] of the
SQLFORM.factory, only the last validator of the 'requires' list is
enforced. Is this a bug? The tried code is:
form=SQLFORM.factory(Field('Optimizers',requires=[IS_IN_SET(options,multiple='multiple'),
IS_NOT_EMPTY()] ))
