Description of the project

The questionnaires controller had several issues; this project aimed to address some of them, including:

  • Remove or move logic that should reside elsewhere, e.g. in a model class.
  • Remove logic and references to logic that is no longer being used.

Files modified in the project

  1. app/controllers/questionnaires_controller.rb
  2. app/views/questionnaires/_questionnaire.html.erb
  3. app/views/questionnaires/edit_questionnaire.html.erb (deleted)
  4. spec/controllers/questionnaires_controller_spec.rb

Issues and Improvements

The assign_instructor_id method

Problems

This method had two issues:

  1. Its name was misleading because it did not actually assign a value; it simply obtained a value from the user in the session.
  2. It was delving into implementation details of the User class.
Solution

The equivalent logic was already implemented in the User class's instructor_id method, so calls to the assign_instructor_id method were simply replaced with:

session[:user].instructor_id

A description in spec/controllers/questionnaires_controller_spec.rb was updated to reflect that assign_instructor_id was no longer in scope.

The export and import methods

Problems

These methods were actually no longer being used, because the functionality they provided was moved to the export_file and import_file routes.

Solution
  • The logic was triggered by the presence of the parameters import or export in the save_all_questions action. Code that caused these parameters to be present had been commented out of _questionnaire.html.erb and edit_questionnaire.html.erb in the questionnaire views. The latter file was no longer reachable, as there was no reference to an edit_questionnaire action in config/routes.rb or any direct references to it in the questionnaires controller itself. Thus the commented-out code was removed from _questionnaire.html.erb and the edit_questionnaire.html.erb file was deleted.
  • The logic referencing the parameters and methods was removed from the save_all_questions method.
