Role-Based Permission System - Implementation Summary

✅ Implementation Complete

A comprehensive, production-ready role-based access control (RBAC) system has been successfully implemented using Spatie Laravel Permission v6.21.0 - the industry-standard solution for Laravel applications.

---

🎯 What Was Implemented

1. Backend Infrastructure ✅

Database Layer

• ✅ Spatie permission tables migrated (roles, permissions, model_has_roles, model_has_permissions, role_has_permissions)
• ✅ Permission seeder with 4 predefined roles and 25+ granular permissions
• ✅ Automatic super-admin assignment to first user

Laravel Models & Traits

• ✅ Updated User model with HasRoles trait
• ✅ Helper methods: isSuperAdmin(), isAdmin(), canManageContent()
• ✅ Integrated with existing authentication system

Policies

• ✅ WordPressPostPolicy - Controls post viewing, editing, analyzing, and suggestion application

  • Enforces ownership checks (users can only manage their own site's posts)
  • Admin override (admins can manage all posts)
  • Permission-based authorization

• ✅ UserPolicy - Controls user management operations

  • Self-protection (users can't delete themselves)
  • Super-admin protection (only super-admins can delete super-admins)
  • Role-based restrictions

Controllers

• ✅ UserManagementController - Full user role management
  • List users with roles
  • Assign/remove roles
  • Delete users with safety checks
  • Permission guards on all methods

Middleware

• ✅ Updated HandleInertiaRequests to share user permissions and roles with React frontend
• ✅ Route-level permission middleware (can:permission.name)

---

2. Frontend Infrastructure ✅

React Hooks

• ✅ usePermissions hook (resources/js/hooks/usePermissions.ts)
  • can(permission) - Check single permission
  • canAny(permissions[]) - Check if user has any permission
  • canAll(permissions[]) - Check if user has all permissions
  • hasRole(role) - Check specific role
  • hasAnyRole(roles[]) - Check if user has any role
  • hasAllRoles(roles[]) - Check if user has all roles
  • isSuperAdmin() - Quick super-admin check
  • isAdmin() - Quick admin check (super-admin or admin)
  • canManageContent() - Quick content manager check

React Components

• ✅ PermissionGate component (resources/js/components/PermissionGate.tsx)
  • Declarative permission checking in JSX
  • Supports single/multiple permissions
  • Supports single/multiple roles
  • requireAll prop for AND logic
  • fallback prop for denied access UI
  • Comprehensive examples in JSDoc

UI Integration

• ✅ PostAnalysis Show page updated with permission checks
  • "Re-analyze" button only for users with posts.analyze
  • "Apply Suggestion" button only for users with posts.apply-suggestions
  • Graceful permission-denied messages
  • Maintains full functionality for authorized users

---

3. Routing & Access Control ✅

New Routes

// User Management (requires 'users.view' permission)
GET    /users                         - List all users
POST   /users/{user}/assign-role     - Assign role to user
POST   /users/{user}/remove-role     - Remove role from user
DELETE /users/{user}                 - Delete user

Protected Existing Routes

All dashboard routes now respect permissions through policies and middleware.

• Only super-admins can assign/remove the super-admin role
• Only super-admins can delete other super-admins

🚀 Quick Start Guide

For Developers

Backend Permission Check

// In controllers
abort_unless(auth()->user()->can('posts.analyze'), 403);

// Using policies
$this->authorize('analyze', $post);

// In blade/controllers
if ($user->hasRole('admin')) {
    // Admin logic
}

Frontend Permission Check

// Using hook
const { can, hasRole } = usePermissions();

if (can('posts.analyze')) {
    // Show analyze button
}

// Using component
<PermissionGate permission="posts.analyze">
    <AnalyzeButton />
</PermissionGate>

For System Administrators

Assign Role to User

# Via Tinker
php artisan tinker
>>> $user = User::find(1);
>>> $user->assignRole('admin');

# Or via UI
Navigate to /users in your browser

Add New Permission

1. Edit database/seeders/RolesAndPermissionsSeeder.php
2. Add permission to $permissions array
3. Assign to desired roles
4. Run: php artisan db:seed --class=RolesAndPermissionsSeeder

🔐 Security Features

1. ✅ Ownership Validation - Users can only manage their own WordPress sites' posts
2. ✅ Admin Override - Admins/Super-admins can manage all resources
3. ✅ Self-Protection - Users cannot delete themselves
4. ✅ Super-Admin Protection - Only super-admins can delete super-admins
5. ✅ Role Assignment Protection - Only super-admins can assign super-admin role
6. ✅ Permission Caching - Optimized database queries with Spatie's caching
7. ✅ Frontend-Backend Sync - Permissions shared via Inertia middleware
