response.rb

response.rb is the class that manages the response to all rubrics in Expertiza. if someone fills out a review form, the instance of the review form is a Response. If someone gives feedback (a “rejoinder”) to an author, that is a Response too. Or if someone evaluates a teammate contribution, fills out a survey, or takes a quiz, they are creating a Response.

Note: Method display_as_html writes the HTML for displaying a rubric.  This would ordinarily be view code, but it is used by so many different views that it is done here.  Questions are written out in the order of their sequence number (anyone who creates a rubric can specify sequence numbers for questions).  After all questions are displayed, there is a blank for an additional comment.

Ensure score calculations utilize the weight of questions

When the get_maximum_score() function is called it takes care of the weight of the question. It multiplies the weight to the score and adds it to the final score.

def get_maximum_score()
    # only count the scorable questions, only when the answer is not nil (we accept nil as answer for scorable questions, and they will not be counted towards the total score)
    total_weight = 0
    scores.each do |s|
      question = Question.find(s.question_id)
      if !s.answer.nil? && question.is_a?(ScoredQuestion)
        total_weight+=question.weight
      end
    end
    if scores.empty?
      questionnaire = questionnaire_by_answer(nil)
    else
      questionnaire = questionnaire_by_answer(scores.first)
    end
    total_weight*questionnaire.max_question_score
  end

response_helper.rb

response_helper.rb contains helper methods that display the questionnaires and rearrange questions so that the most frequently answered questions are at the bottom while the less frequently answered questions are at the top.

Method is no longer being used in Expertiza and has been removed.
