Story 6.8: System Settings

Epic Reference

Epic 6: Admin Dashboard

User Story

As an admin, I want to configure system-wide settings, So that I can customize the platform to my needs.

Dependencies

• Story 1.2: Authentication & Role System (admin auth, User model)
• Story 8.1: Email Infrastructure Setup (mail configuration for test email)

Navigation Context

• Accessible from admin dashboard sidebar/navigation
• Route: /admin/settings
• Named route: admin.settings

Acceptance Criteria

Profile Settings

• Admin name
• Email
• Password change
• Preferred language

Email Settings

• Display current sender email from config('mail.from.address')
• Display current sender name from config('mail.from.name')
• "Send Test Email" button that sends a test email to admin's email address
• Success/error feedback after test email attempt

Notification Preferences (Future Enhancement - Not in Scope)

Note: The following are documented for future consideration but are NOT required for this story's completion. All admin notifications are currently mandatory per PRD.

• Toggle admin notifications (future)
• Summary email frequency (future)

Behavior

• Settings saved and applied immediately
• Validation for all inputs
• Flash messages for success/error states
• Password fields cleared after successful update

Technical Notes

Database Migration Required

Add preferred_language column to users table:

// database/migrations/xxxx_add_preferred_language_to_users_table.php
Schema::table('users', function (Blueprint $table) {
    $table->string('preferred_language', 2)->default('ar')->after('remember_token');
});

Files to Create/Modify

File	Action	Purpose
resources/views/livewire/admin/settings.blade.php	Create	Main settings Volt component
app/Mail/TestEmail.php	Create	Test email mailable
resources/views/emails/test.blade.php	Create	Test email template
database/migrations/xxxx_add_preferred_language_to_users_table.php	Create	Migration

app/Models/User.php	Modify	Add preferred_language to fillable

TestEmail Mailable

// app/Mail/TestEmail.php
namespace App\Mail;

use Illuminate\Mail\Mailable;
use Illuminate\Mail\Mailables\Content;
use Illuminate\Mail\Mailables\Envelope;

class TestEmail extends Mailable
{
    public function envelope(): Envelope
    {
        return new Envelope(
            subject: __('messages.test_email_subject'),
        );
    }

    public function content(): Content
    {
        return new Content(
            view: 'emails.test',
        );
    }
}

Volt Component Structure

<?php
// resources/views/livewire/admin/settings.blade.php

use App\Mail\TestEmail;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Mail;
use Illuminate\Validation\Rule;
use Livewire\Volt\Component;

new class extends Component {
    public string $name = '';
    public string $email = '';
    public string $current_password = '';
    public string $password = '';
    public string $password_confirmation = '';
    public string $preferred_language = 'ar';

    public function mount(): void
    {
        $user = auth()->user();
        $this->name = $user->name;
        $this->email = $user->email;
        $this->preferred_language = $user->preferred_language ?? 'ar';
    }

    public function updateProfile(): void
    {
        $this->validate([
            'name' => ['required', 'string', 'max:255'],

        } catch (\Exception $e) {

        }
    }
}; ?>

Edge Cases & Error Handling

• Wrong current password: Validation rule current_password handles this automatically
• Duplicate email: Rule::unique with ignore(auth()->id()) prevents self-collision
• Email send failure: Wrap in try/catch, show user-friendly error message
• Empty preferred_language: Default to 'ar' in mount() if null

Testing Requirements

Test Scenarios

Profile Update Tests:

test('admin can view settings page', function () {
    $admin = User::factory()->create();

    $this->actingAs($admin)
        ->get(route('admin.settings'))
        ->assertOk()
        ->assertSeeLivewire('admin.settings');
});

test('admin can update profile information', function () {
    $admin = User::factory()->create();

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->set('name', 'Updated Name')
        ->set('email', 'updated@example.com')
        ->set('preferred_language', 'en')
        ->call('updateProfile')
        ->assertHasNoErrors();

    expect($admin->fresh())
        ->name->toBe('Updated Name')
        ->email->toBe('updated@example.com')
        ->preferred_language->toBe('en');
});

test('profile update validates required fields', function () {
    $admin = User::factory()->create();

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->set('name', '')
        ->set('email', '')
        ->call('updateProfile')
        ->assertHasErrors(['name', 'email']);
});

test('profile update prevents duplicate email', function () {
    $existingUser = User::factory()->create(['email' => 'taken@example.com']);
    $admin = User::factory()->create();

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->set('email', 'taken@example.com')
        ->call('updateProfile')
        ->assertHasErrors(['email']);
});

Password Update Tests:

test('admin can update password with correct current password', function () {
    $admin = User::factory()->create([
        'password' => Hash::make('old-password'),
    ]);

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->set('current_password', 'old-password')
        ->set('password', 'new-password')
        ->set('password_confirmation', 'new-password')
        ->call('updatePassword')
        ->assertHasNoErrors();

    expect(Hash::check('new-password', $admin->fresh()->password))->toBeTrue();
});

test('password update fails with wrong current password', function () {
    $admin = User::factory()->create([
        'password' => Hash::make('correct-password'),
    ]);

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->set('current_password', 'wrong-password')
        ->set('password', 'new-password')
        ->set('password_confirmation', 'new-password')
        ->call('updatePassword')
        ->assertHasErrors(['current_password']);
});

test('password update requires confirmation match', function () {
    $admin = User::factory()->create([
        'password' => Hash::make('old-password'),
    ]);

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->set('current_password', 'old-password')
        ->set('password', 'new-password')
        ->set('password_confirmation', 'different-password')
        ->call('updatePassword')
        ->assertHasErrors(['password']);
});

Test Email Tests:

test('admin can send test email', function () {
    Mail::fake();
    $admin = User::factory()->create();

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->call('sendTestEmail')
        ->assertHasNoErrors();

    Mail::assertSent(TestEmail::class, fn ($mail) =>
        $mail->hasTo($admin->email)
    );
});

test('test email failure shows error message', function () {
    Mail::fake();
    Mail::shouldReceive('to->send')->andThrow(new \Exception('SMTP error'));

    $admin = User::factory()->create();

    Volt::test('admin.settings')
        ->actingAs($admin)
        ->call('sendTestEmail')
        ->assertSessionHas('error');
});

• Test email sends successfully (or shows error on failure)
• Email settings display current sender info from config
• All flash messages display correctly (success/error)
• UI follows Flux UI component patterns
• All tests pass (php artisan test --filter=SettingsTest)
