In the following controller when edit a row and submit,
request.vars.survey_id changes from '3' to ['3', '3']
but not if I click on 'Back' without editing. Why?
I had to use the following workaround:
survey_id = request.vars.survey_id[0] if isinstance(survey_id, list)
else request.vars.survey_id
@auth.requires_login()
def edit_survey():
response.view = 'default/survey_create.html'
survey_id = request.vars.survey_id
if isinstance(survey_id, list):
survey_id = survey_id[0]
survey = db.survey[survey_id]
db.questions.id.readable = False
if survey_id:
query = db.questions.survey_id== survey_id
fields = [db.questions.question_number,
db.questions.question,db.questions.answer_type,
db.questions.id]
questions = SQLFORM.grid(query,
editable = True,
deletable = True,
create = True,
searchable = False,
maxtextlength = 100,
orderby=db.questions.question_number)
header = H3(T('%s for editing' % db.survey[survey_id].name))
else:
header = H3(T('No valid survey selected'))
form = ''
return dict(header = header, form = questions)
