Massimo,
Thank you.
As always, if I'm doing something wrong I would be delighted to know
it.
>From the limited checking I have been able to do, I think the problem
is in the SELECT helper, not in the validator.
Anyway, here's the code.
## model
db.define_table('buckslip_types',
Field('name', length=32),
)
db.define_table('buckslips',
Field('type', db.buckslip_types),
Field('status', 'list:string'),
Field('date_received', 'datetime'),
Field('date_approved', 'datetime'),
Field('date_posted', 'datetime'),
Field('comments', 'text'),
Field('document_filename', length=256),
Field('document','upload')
)
db.buckslips.type.requires = IS_IN_DB(db, 'buckslip_types.id',
'%(name)s', zero=None)
db.buckslips.status.requires = IS_IN_SET(['received', 'approved',
'disapproved', 'posted'],
multiple=False
)
## controller buckslips.py
def edit():
record = db.buckslips(request.args[-1]) or redirect(URL('index'))
url = URL('download')
db.buckslips.document.writable = False
# db.buckslips.status.widget = my_select_widget
fields=['date_received', 'status', 'document', 'comments']
form = SQLFORM(db.buckslips, record, deletable=False,
upload=url, fields=fields,
)
if request.vars.document!=None:
form.vars.document_filename= request.vars.document.filename
if form.process().accepted:
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
