Upgraded, but the error is still there. It's failing at the SQLFORM
validation in dal.py, I don't even get the chance to access session
variables myself. Also, list:integer fields leave an empty field behind
Is there a way from within the DAL to remove empty entries on list:integer
(as I can't rely on my users to not create empty entries when using the
form)?
def index():
"""
"""
form=SQLFORM.factory(
Field('employees', 'list:integer' ),
)
my_emps=[]
if form.process(session=None).accepted:
mvars=form.vars.employees
if mvars:
response.flash=myvars
for a in mvars:
my_emps.append(a)
else:
my_emps.append(mvars)
return dict(form=form, my_emps=my_emps)
