CSC/ECE 517 Spring 2022 - E2217: Refactor questionnaires controller

This page describes the changes made for the Spring 2022 OSS Project E2217: Refactoring Questionnaires Controller

Description

This project focused on sanding down the rough edges of questionnaires_controller.rb through the removal of the unused create_questionnaire method, breaking up the exceedingly long create method, transfer of hardcoded values in the add_new_questions method, and general code cleanup.

Problems and Solutions

• Problem: The create_questionnaire method is not used.create_questionnaire has no immediate apparent calls, and appears to have the same functionality as create.
  • Solution:

• Problem: The create method is 49 lines long, and needs to be broken up
  • Solution:

• Problem: There are three checks for whether a question is a QuizQuestionnaire. These checks are likely unnecessary, and testing the class of an object carries potential problems.
  • Solution:

• Problem: There are assignment values hardwired into the code in add_new_questions. Although these fields are okay to default to the given values, these should be defined constants
  • Solution: As these values related to ScoredQuestion items, constants were created in scored_question.rb. add_new_questions now uses these class constants when assigning default values for fields. These values are all changeable in the UI after initialization.

Addition of constants to scored_question.rb
