Implementation Summary: Laravel Permission-Based Role System with Grade Appeals

🎯 Requirements Completed

✅ 1. Auto-assign 'exstudent' role to newly registered users

Location: app/Http/Controllers/Web/UsersController.php - doRegister() method

  • New users automatically receive the 'exstudent' role upon registration
  • Implementation: $user->assignRole('exstudent');

✅ 2. Teachers and managers can see appeal status beside any grade

Location: resources/views/grades/list.blade.php

  • Added "Appeal Status" column visible to users with show_exgrades permission
  • Displays detailed status with timestamps and reasons:
    • 🔘 No Appeal (none)
    • ⚠️ Pending (with reason and submission time)
    • ✅ Approved (with response and approval time)
    • ❌ Rejected (with response and rejection time)
    • ℹ️ Appeal Closed (when grade is modified)

✅ 3. Students can press an "appeal" button beside any grade

Location: resources/views/grades/list.blade.php

  • Appeal button appears for students on their own grades (when status is 'none')
  • Modal form allows students to submit detailed appeal reasons
  • Protected by submit_grade_appeal permission

✅ 4. Show teacher response with approval/rejection status

Location: Multiple files

  • View: Enhanced status display shows response text and timestamps
  • Controller: GradesController@respondToAppeal() handles teacher responses
  • Modal: Teacher response form with approval/rejection options

✅ 5. Users can see their permissions in their profile

Location: resources/views/users/profile.blade.php & app/Http/Controllers/Web/UsersController.php

  • Profile displays all user permissions (direct + role-based)
  • Shows permissions as green badges with readable names
  • Comprehensive permission aggregation from roles and direct assignments

✅ 6. Grade changes automatically close appeals

Location: app/Http/Controllers/Web/GradesController.php - save() method

  • Detects when grade is modified
  • Automatically sets appeal_status to 'closed' for active appeals
  • Prevents stale appeals on modified grades

🗄️ Database Schema Changes

Grades Table (Migration: add_appeal_functionality_to_grades_table)

appeal_status ENUM('none', 'pending', 'approved', 'rejected', 'closed') DEFAULT 'none'
appeal_reason TEXT NULL
appealed_at TIMESTAMP NULL
appeal_response TEXT NULL
appeal_responded_at TIMESTAMP NULL

🔐 Permissions System

New Permissions Created

  1. submit_grade_appeal - Students can submit appeals
  2. respond_to_grade_appeal - Teachers can respond to appeals
  3. view_grade_appeals - View appeal status information

Permission Assignments

  • exstudent role: submit_grade_appeal
  • exteacher role: respond_to_grade_appeal, view_grade_appeals
  • exmanager role: respond_to_grade_appeal, view_grade_appeals
