Hi people,
I did alredy post this problem on the ToscaWidgets group but no
response.
Could be here ... I'm more lucky.
I'm in truble with validation in TG 1.0.8 ToscaWidgets application.
I did search the discussion to find a solution but seems that I'm
alone with this problem...
So at fisrt my configuration and the code:

print 'role',role
print 'activity', activity
activity_form = get_activity_form2(role=role)
return dict(activity_form=activity_form,activity=activity)
@error_handler(activity1)
@validate(form=get_activity_form2)
@expose()
def save_activity1(self, **kw):
if cp.request.method != 'POST':
raise Exception('save_activity must be a POST request')
# TBD: save activity to database
if kw['id']:
activity = session.query(model.Activity).filter_by
(activity_id=int(kw['id']))[0]
else:
activity = model.Activity()
activity.user_id = int(kw['user'])
activity.project_id = int(kw['project'])
date = map(int,request.params['date'].split('/'))
activity.activity_date = datetime.date(date[2],date[1],date
[0])
activity.role_id = int(kw['role'])
activity.activitytype_id = int(kw['activitytype'])
activity.activity_minutes = int(kw['minutes'])
session.add(activity)
session.commit()
raise redirect('/activity1',activity_id =
activity.activity_id, user_id = activity.user_id)
The code run and I obtain the 'activty_form' where I can input the
values and save and update.
But when I try to do an error, selecting a role option that have no
activitytype options associated, and than saving,
the error is intercepted by the validate/error_handler couple of lines
correctly but the activity_form is showed not complete.
The form show the the correct values of the date, user, id (if one)
and minutes but the selected values of the select are not selected.
The activitytype is correctly signed like empty with the correct
message but the role and the project filed are not selected with the
values that I choise before the save.
I did try to trace the status of activity dictionary that I pass to
the form and the values are correctly setted. The activitytype field
alone are without value, obviously.
I think to be wrong in something. If I follow the tutorial and the
documentation it seems also superfluous the part of code:
if tg_errors:
activity = {}
if 'id' in kw:
activity['id'] = int(kw['id'])
if 'project' in kw:
activity['project'] = int(kw['project'])
if 'date' in kw:
activity['date'] = kw['date']
if 'role' in kw:
activity['role'] = int(kw['role'])
if 'activitytype' in kw:
activity['activitytype'] = int(kw['activitytype'])
if 'minutes' in kw:
activity['minutes'] = int(kw['minutes'])
where I set the values of activity in case of error. From the
documentation it seems to exist a kind of magic solution to do that
but I did'nt able to realise.
Thanks for help.
Best regards
Enrico Secco
