CSC/ECE 517 Fall 2023 - E2383. Grading Audit Trail

Introduction

Problem Statement

After an instructor gave a grade to an assignment, there is no way to track who gave the grade. A grading audit trail must be created and the following information needs to be stored:

1. When a grade is assigned by an instructor, there needs to be an indication of who did it and when it was done.

2. Comments previously provided by other instructors must also be preserved.

This information needs to be stored every time an instructor edits a grade/comment and clicks the save button.

Overview of Major Changes By Previous Teams

E1934

• A new table was added to the database (grading_history), along with the corresponding model (grading_history.rb) and controller (grading_history_controller.rb).
  • Whenever an instructor submits a new grade, or edits an existing grade, the grading_history_controller saves a new history entry to the database.

• Two models for specific types of histories were added: review_grading_history.rb, and submission_grading_history.rb.

• A view for displaying the grading history of a particular assignment or review was added (grading_histories/index.html.erb).
