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 renaming problem required us to change a few methods 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 methods.

The course_team is a subclass of the team class. CourseTeams are a type of team that an instructor can use throughout an entire semester, providing consistency in team membership over time. The course_team model is responsible for completing various tasks, including returning the course of the team, adding a participant to the CourseTeam, and copying the CourseTeam Participants to AssignmentTeam Participants. There are methods for importing and exporting data to/from CSV files for CourseTeam objects. The problem description lists code smells/issues that need to be fixed. The issues that we fixed were deleting unused methods, renaming methods, and changing method calls, changing rspec expectations, adding meaningful comments. To refactor methods, DRY principles were used. In addition, analogous changes were made in the assignment_team model.

Description

What it does: The Course model and CoursesController is responsible for managing the courses. This system allows admin to create a new course, edit the course and update the existing course. It also allows you to create a copy of an existing course, etc.

What needs to be done: You have to exactly follow the reimplementation guidelines as stated on top and make sure that you have covered all the functionality that is required for the Courses. You will be responsible for the entire functionality of the Courses, the model and controller, and the detailed rspec test, testing all the pass and fail scenarios, for the rest endpoints are compulsory. As mentioned in the guideline, take reference from the User (model & controller) implementation and look at roles_rspec.rb for the test, roles_rspec is not complete and there is potential for better testing but you can use that as a starting point.
