Question

I am making an application in Ruby on Rails which will ask users multiple choice questions. I want to upload questions to the database from an excel file. How can I do it?

Answer 1

Save the Excel spreadsheet as a CSV file then use a CSV parser, perhaps in a rake file:

In lib/taks/import.rake:

require 'fastercsv'
namespace :import => :environment do
   task :questions do
     FasterCSV.foreach("path/to/file.csv") do |row|
           q = Question.create(:question=>row[0], etc...)
           PossibleAnswer.create(:question=>q, :answer=>row[1], etc....) #providing PossibleAnswer belongs_to Question
      end
   end 
end

Then run “rake import:questions”
