CSC/ECE 517 Fall 2024 - E2484. Reimplement participants controller.rb

About Expertiza

Expertiza is an open source project based on Ruby on Rails framework. Expertiza allows the instructor to create new assignments and customize new or existing assignments. It also allows the instructor to create a list of topics the students can sign up for. Students can form teams in Expertiza to work on various projects and assignments. Students can also peer review other students' submissions. Expertiza supports submission across various document types, including the URLs and wiki pages.

Introduction

This project aims to reimplement the participants_controller.rb and participants_helper.rb in the new Expertiza system. The participants_controller.rb manages participants within assignments, and this reimplementation focuses on streamlining its methods, eliminating redundancy, and enhancing code readability and maintainability.

Requirements

Implement participants_controller.rb Methods: Fully implement each controller method with the same functionality as the current controller.

Import from participants_helper.rb : Integrate relevant helper methods to streamline functionality and remove redundancy.

API Creation: Expose API endpoints for all necessary methods to enable seamless access and integration from the frontend. Ensure that each endpoint follows best practices for RESTful API design, including proper error handling and secure data access.

Testing with rswag: Create test cases for all methods, focusing on edge cases, and generate rswag documentation.

Swagger UI Video Documentation: Record a video walkthrough of API endpoints in Swagger UI, showcasing each method’s functionality.

Existing Issues

Reimplement participants_controller.rb while addressing the following:

Refactor code to comply with the Open-Closed Principle.

Introduce dependency injection where necessary.

Reduce excessive conditional statements.

Include sufficient code tests to verify functionality.

Enhance comments to better explain each method's functionality, purpose, and rationale for keeping or modifying particular aspects of the code.

Provide a more detailed explanation of design choices and refactoring steps.

Design Patterns
