Overview of Expertiza
Expertiza is an open-source software written using Ruby on Rails which functions as a learning management software system. It has many different functions and abilities including the ability to create assignments, quizzes, assignment groups, and topics, and also a complete mechanism for providing peer reviews and feedback for other groups and other teammates. Part of its functionality is a system containing information about the course and its associated teams respectively. The Course and CourseTeam which are the models primarily addressed in this project are both critical components in providing this functionality.
Description of Project
course model stores information about the instructor and institution and is associated with other models such as User, CourseParticipant, CourseTeam, Assignment, AssignmentParticipant, and Notification. The course model is responsible for completing a variety of tasks, including returning course teams, returning the submission directory for the course, viewing participants enrolled in the course, adding a participant to the course, copying the Assignment Participants to Course Participants, and checking whether a user is part of any CourseTeam. The problem description lists code smells that need to be fixed. We fixed some issues, such as deleting the unused methods and renaming methods to indicate their action. The remaining problem required us to change a few method calls where the function to be renamed was used. Also, to reduce the cognitive complexity of the copy_assignment_participants method, we created a method to separate the raising error functionality. Comments were added to indicate the action of the method.
The password_retrieval_controller deals with the process of updating and resetting a user password. The send_password method generates a token and appends it to a password reset URL. If a user submits a valid email address on the password_retrieval/forgotten view, the URL is sent to the user's email. When a user goes to the password reset URL, the token parameter is decrypted and checked for expiration. Next, the password_retrieval/reset_password view is loaded where a user enters an updated password and is sent back to the home page. In this project, the method was refactored in the following ways: to adhere to DRY principles, removal of hardwired constants, renaming of methods and variables, and enhanced comments. In addition, RSpec testing coverage of the controller was improved from 63.33% to 91.8% through a series of new tests that validate the functionality of the update_password and send_password methods.

Checked and Removed get_participant method
|
Checked the usage of Method through IDE whether the function is used, the only call was from course_spec.rb and not from anywhere else. Hence, removed from course.rb

Renamed copy_participants method
|
Renamed copy_participants to copy_assignment_participants which makes more sense and a clear idea of how method works and what is the purpose of method.

Removed add_member method from course_team model
|
Assignment_team and Course_team are subclasses of Team. Both should follow the similar logic of adding members of respective teams. As of for, add_participants, usage is different for course.rb and course_team.rb, hence it should be present in both. However, to make the code more consistent among classes, team, course_team, and assignment_team, the add_member method should only be present in the team class.

Removed assignment_id
|
CourseTeam and AssignmentTeam inherit from Team class. The teams' table has an attribute parent_id that helps determine whether the team is AssigmentTeam or CourseTeam. Thus, there is no need for assignment_id in the CourseTeam class and no need for course_id in AssignmentTeam class. It will be a bad coding practice to call the assignment_id method on the CourseTeam object, calling the course_id method on the AssignmentTeam object as it would be inappropriate.

Renamed copy method as copy_to_assignment_team
|
As this method is copying a CourseTeam to an AssignmentTeam, renamed it as copy_to_assignment_team. A suggestion for copy method in AssignmentTeam would be to rename it as copy_to_course_team.
