Project Description

Classes : student_quiz_controller.rb
What it does : This class records the quizzes that the student has attempted and its progress and also submits grades for the essays in the quizzes attempted by the student.
What has to be changed :

• change list to index (and others in the RESTful style)
• Pluralize the class (StudentQuizzesController)
• only set one instance variable (use a form object if necessary)
• graded? - review boolean zen
• Modify methods to conform to RESTful style
• Reducing the number of instance variables per action to one
• Code cleanup by using string interpolation instead of concatenation, replacing '==' with eql? and :key =>'value' with key: 'value', modifying declarations of Arrays and Hashes,removing commented out code
• Replace find_by with where to follow Rails 4.0 conventions

Modification to Existing Code

RESTful style implementation

• Modifications to student_quiz_controller.rb :

The purpose of the list method in StudentQuizzes Controller is to list all registered users. This implementation did not conform to RESTful guidelines. The list method was renamed to index and cleaned up to remove unnecessary business logic. Further, we refactored all the references of list method in StudentQuizControllers, StudentQuiz views, StudentQuiz tests index method.
