Hi, I have the same problem.
I defined the following tables:
db.define_table('t_questions',
Field('f_question', type='text', label=T('Question')),
Field('f_question_number', type='integer', label=T('Question number')),
Field('f_lecture', type='reference t_activities', label=T('Lecture')),
auth.signature, format='%(f_question)s',
plural="Questions",
migrate=settings.migrate)
db.define_table('t_answers',
Field('f_question', type='reference t_questions', label=T('Question')),
Field('f_option', type='string', label=T('Option')),
Field('f_points', type='integer', label=T('Points')),
Field('f_iscorrect', type='boolean', label=T('Is Correct')),
auth.signature, format='%(f_option)s',
plural="Answers",
migrate=settings.migrate)
and then defined the smartgrid:
questions = SQLFORM.smartgrid(db.t_questions, linked_tables=['t_answers'],
fields = dict(t_questions =(db.t_questions.f_question_number,
db.t_questions.f_lecture, db.t_questions.f_question)),
field_id = (db.t_questions.id),
orderby = dict(t_questions =
[db.t_questions.f_lecture|db.t_questions.f_question_number]),#|db.t_questions.f_question_number,
csv = False,
deletable = True,
editable = True,
create = True,
paginate=100
)
When the smartgrid is displayed I click on edit a question, then in the
edit page I click on "Answers", it shows the anwers for that question and
when I click in "View "Edit" or "Delete" it gives me an error:
AttributeError: 'Row' object has no attribute 'f_option'
That's because those buttons make reference to:
https://mysite/app/controller/questions/t_questions/t_answers.f_question/6/view/
t_questions/14?_signature=c93a35518f7922dd8e85a6b1dace5b797eb5a394
which is wrong as it must be "t_answers/14"
Any idea?
Thank you very much.
Regards
