Hello,
I had an application with rails 4 & rubyzip gem installed.
I have 3 tables - students, exams & results.

I followed this video http://railscasts.com/episodes/362-exporting-csv-and-excel

I'm able to download individual table csv files but not all 3 at a single click.

And I want to download all these 3 table csv files as a zip file with rubyzip or something else.

Please help me. I searched every end of google but didn't find an accurate result.

answers model
validates :reference_id, uniqueness: { scope: :question_id }

It is applying only for questions but what to do if i want apply through the survey ?
