Using simple_form collections to save and load a comma separated values string as checkboxes

Based on https://gist.github.com/jchunky/3444833

add the collection helper methods to your model

class QuizAnswer < ActiveRecord::Base
  ...  
  def user_answer_collection
    return [] if !user_answer
    user_answer.split(",")

end
