# Role-Based Access Control - Disconnection Management System

**Date**: May 25, 2026  
**Status**: ✅ **FULLY CONFIGURED**

---

## 🔒 Access Control Overview

The Disconnection Management system is restricted to **Super Admin** and **Company Admin** roles only.

### **Allowed Roles:**
- ✅ `super_admin` - Full access to all disconnection management features
- ✅ `company_admin` - Full access to all disconnection management features for their company

### **Denied Roles:**
- ❌ `cashier` - No access
- ❌ `meter_reader` - No access
- ❌ `customer` - No access
- ❌ Any unauthenticated user - Redirected to login

---

## 📍 Authorization Layers

### **Layer 1: Route Middleware** (`routes/web.php`)

All disconnection routes are protected with the `check.role:super_admin|company_admin` middleware:

```php
Route::middleware('check.role:super_admin|company_admin')->group(function () {
    Route::get('/disconnections', [DisconnectionController::class, 'index'])->name('disconnections.index');
    Route::get('/disconnections/client/{client}', [DisconnectionController::class, 'clientDetails'])->name('disconnections.client-details');
    Route::post('/disconnections/{billing}/notice', [DisconnectionController::class, 'sendDisconnectionNotice'])->name('disconnections.send-notice');
    Route::post('/disconnections/{billing}/disconnect', [DisconnectionController::class, 'disconnect'])->name('disconnections.disconnect');
    Route::post('/disconnections/reconnect/{client}', [DisconnectionController::class, 'reconnect'])->name('disconnections.reconnect');
    Route::get('/disconnections/report/late-fees', [DisconnectionController::class, 'lateFeeReport'])->name('disconnections.late-fee-report');
    Route::get('/disconnections/history/{client}', [DisconnectionController::class, 'clientHistory'])->name('disconnections.client-history');
});
```

**Effect**: Users without super_admin or company_admin roles cannot even access the routes. They receive a 403 Forbidden error.

---

### **Layer 2: Controller Middleware** (`app/Http/Controllers/DisconnectionController.php`)

The controller constructor includes an additional authorization middleware check:

```php
public function __construct(LatePaymentService $latePaymentService)
{
    // Only super_admin and company_admin can access disconnection management
    $this->middleware(function ($request, $next) {
        $user = Auth::user();
        if (!$user || !in_array($user->role->name, ['super_admin', 'company_admin'])) {
            abort(403, 'Unauthorized - Only Super Admin and Company Admin can access this resource.');
        }
        return $next($request);
    });

    $this->latePaymentService = $latePaymentService;
}
```

**Effect**: Even if someone bypasses route middleware, the controller verifies the role before executing any method.

---

### **Layer 3: Controller Company-Level Authorization**

Each controller method verifies the client/billing belongs to the user's company:

```php
public function clientDetails(Client $client)
{
    $company = Auth::user()->company;
    
    if ($client->company_id !== $company->id) {
        abort(403, 'Unauthorized');
    }
    
    // ... rest of method
}
```

**Effect**: Super Admin can only see data for companies they have access to. Company Admin can only see their own company's data.

---

### **Layer 4: View-Level Authorization** (Blade Templates)

All disconnection views check the user's role and display an access denied message if unauthorized:

```blade
@extends('layouts.app')

@section('content')
@if(in_array(auth()->user()->role->name, ['super_admin', 'company_admin']))
    <!-- View content here -->
@else
    <!-- Access Denied Error Message -->
@endif
@endsection
```

**Views Protected:**
- ✅ `resources/views/disconnections/index.blade.php`
- ✅ `resources/views/disconnections/client-details.blade.php`
- ✅ `resources/views/disconnections/late-fee-report.blade.php`
- ✅ `resources/views/disconnections/client-history.blade.php`

**Effect**: If somehow a user with insufficient permissions reaches a view, they see an "Access Denied" message instead of the page content.
