Student Dashboard (Backend)

[Luqman1008]

Description:

This PR introduces the backend implementation for the Student Dashboard, including a new StudentDashboardController with endpoints to manage and retrieve essential student-related data.

Key Features Implemented:

1. Student Dashboard Controller:

   • index Endpoint:

     • Returns @upcoming_evaluations, listing all upcoming evaluations associated with the projects of the current student.
     • Returns @avg_ratings, a map containing the average values of all rating categories for the student.

   • teams Endpoint:

     • Retrieves @student_teams, which includes a JSON response of all projects linked to the student and all associated teams within those projects. If the student belongs to a team.

   • evaluations Endpoint:

     • Provides @student_evaluations, which consists of all projects linked to the student, completed evaluations, and pending evaluations where the evaluator_id is the current student.

   • feedback Endpoint:

     • Returns @avg_ratings (average rating scores for the current student) and @received_evaluations, a list of all evaluations where the student is the evaluatee and the status is marked as completed.

2. Changes to the Evaluation Model:

   • Automatic Status and Date Management:
     • Added logic to handle status and date_completed based on the presence of ratings. If any rating fields are missing, the status is set to pending, and the date_completed is set to nil. If all ratings are present, the status is updated to completed, and date_completed is set to the current date.

3. Rspec Tests:

   • Added Rspec test cases to validate the functionality of all the newly created endpoints in StudentDashboardController.

Additional Changes:

• Migrations:
  • Updated the evaluations table to allow NULL values for ratings to facilitate the new logic in the Evaluation model.
