i want to do this: user selects some of the questions (checkboxes) and
saves them a test (SQLFORM). it doesn't matter how to do this. with or
without form, redirects or in one page.
i was using q's to retrieve selected checboxes,
i did it with jquery. my way:
page1: test.html
select page. i retrieve selected questions with jquery and generate a link
like this: /create_test?questions=1,2,3,4,9,10
page2: create_test.html
save test with questions, gives name with SQLFORM.
it works.
my db:
db.define_table('questions',Field('question_image').......)
db.define_table('tests',Field('name'),Field('questions').....)
i didn't use list:reference. i store question ids as string seperated with
comma.
