When using this form, how can I build a validator (or use some other way)
that ensure that the form will not be accepted if the combination of
survey_id and question_number is not already in the table?
form = SQLFORM.factory(
Field('survey_id', db.survey, default = survey_id),
Field('question_number'),
Field('answer_type', 'integer',
requires=IS_IN_SET([(1,'Text'),
(2, 'Only one option
selected'),
(3, 'More than one
option selected')])))
I have seen the following answer by Anthony on Stackoverflow, but it
breaks in this case:
db.questions.question_number.requires = IS_NOT_IN_DB(
db(db.questions.question_number ==request.vars.question_number),
'survey_id')
The error:
File "/home/js/web2py/gluon/validators.py", line 653, in __call__
(tablename, fieldname) = str(self.field).split('.')
ValueError: need more than 1 value to unpack
Regards
Johann
