Hi everyone,
I am using TG 1.0.6 with SQlAlchemy 0.4.3. What I am working on at the
moment is to make a web app that will browse hierarchical data. In
order to do that I defined a form on which I show a question and
possible answers to that question in the form of SingleSelectField.
Therefore I need to select only the answers relevant to the question.
My controllers.py looks like this:
def rows(key_id):
selected_rows=Zapisi.query.filter(Data.parent_id == key_id).all()
rows_list=[]
for selected_row in selected_rows:
rows_list.append((selected_row.id, selected_row.answer))
return rows_list
class DataSelectForm(TableForm):
fields=[HiddenField('sifra_pitanja',
validator=validators.Int()),
TextField('question', label=_(u'Question')),
SingleSelectField('answer_id',
validator=validators.Int(), label=_(u'Answers'),
options=rows(key_id))]
submit_text=_(u'Select')
dataselect_form=DataSelectForm
class Root(controllers.RootController):
def start(self, **form_data):
try:
key_id=int(form_data['answer_id'])
except:
key_id=1
row=Data.query.filter(Data.id==key_id).first()
value = {'answer_id' : '',
'question' : row.question}
return dict(form=dataselect_form,
form_title='Browse data tree',
action='start',
value=value)
raise redirect('/start')
and got:
SingleSelectField('answer_id', validator=validators.Int(),
label=_(u'Answers'), options=rows(key_id))]
NameError: name 'key_id' is not defined
then I tried defining key_id in the DataSelectForm class like this:
class DataSelectForm(TableForm):
key_id=1
fields=[HiddenField('sifra_pitanja',
validator=validators.Int()),
TextField('question', label=_(u'Question')),
SingleSelectField('answer_id',
validator=validators.Int(), label=_(u'Answers'),
options=rows(key_id))]
submit_text=_(u'Select')
and then
def start(self, **form_data):
try:
key_id=int(form_data['answer_id'])
except:
key_id=1
row=Data.query.filter(Data.id==key_id).first()
value = {'answer_id' : '',
'question' : row.question}
DataSelectForm.key_id=key_id
dataselect_form=DataSelectForm()
return dict(form=dataselect_form,
form_title='Browse data tree',
action='start',
value=value)
raise redirect('/start')
But it just returns answers for key_id=1
Is it possible to work around this (i also tried __init__ approach but
got Name Error again)?
