Problem Statement

Summary of Previous Team's Work

You can read the entirety of the previous team's wiki write-up if desired.

Overview of Major Changes

A new table was added to the database (grading_history), along with the corresponding model (grading_history.rb) and controller (grading_history_controller.rb).

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 (index_html.erb).

Whenever an instructor submits a new grade, or edits an existing grade, the grading_history_controller saves a new history entry to the database.

Modifications to Existing Files

app/controllers/grades_controller.rb
A grading history record is created for every edit to a submission's grade.
app/controllers/review_mapping_controller.rb
A grading history record is created for every edit to a review's grade.

A link to access a review's grade history is shown in the review report table.
