|
|
|

|
|
> See `docs/brand.md` for current color specifications.
|
|
|
|
## Epic Reference
|
|
**Epic 8:** Email Notification System
|
|
|
|
## Dependencies
|
|
**Requires:** Story 8.1 (Email Infrastructure Setup) - base template, queue configuration, SMTP setup
|
|
|
|
## User Story
|
|
As a **new client**,
|
|
I want **to receive a welcome email with my login credentials**,
|
|
So that **I can access the platform**.
|
|
|
|
## Acceptance Criteria
|
|
|
|
### Trigger
|
|
- [x] Sent automatically on user creation by admin
|
|
- [x] Queued for performance (implements `ShouldQueue`)
|
|
- [x] Triggered via admin creation action (recommended approach per Technical Notes)
|
|
|
|
### Content
|
|
- [x] Personalized greeting (name/company)
|
|
- [x] "Your account has been created" message
|
|
- [x] Login credentials (email, password)
|
|
- [x] Login URL link with button
|
|
- [x] Brief platform introduction
|
|
- [x] Contact info for questions
|
|
|
|
### Language
|
|
- [x] Email in user's `preferred_language` field
|
|
- [x] Default to Arabic ('ar') if `preferred_language` is null
|
|
- [x] Arabic template
|
|
- [x] English template
|
|
|
|
### Design
|
|
- [x] Professional branding (inherits from base template in Story 8.1)
|
|
- [x] Call-to-action button: "Login Now" / "تسجيل الدخول"
|
|
|
|
## Technical Notes
|
|
|
|
### Prerequisites from Story 8.1
|
|
- Base email template with Libra branding (navy #0A1F44, gold #D4AF37)
|
|
- Queue configuration for async email delivery
|
|
- SMTP configuration via `.env`
|
|
|
|
### User Model Requirement
|
|
The User model requires a `preferred_language` field. If not already present, add:
|
|
- Migration: `$table->string('preferred_language', 2)->default('ar');`
|
|
- Fillable: Add `'preferred_language'` to `$fillable` array
|
|
|
|
### Files to Create
|
|
|
|
**Mailable Class:**
|
|
- `app/Mail/WelcomeEmail.php`
|
|
|
|
**View Templates:**
|
|
- `resources/views/emails/welcome/ar.blade.php` (Arabic)
|
|
- `resources/views/emails/welcome/en.blade.php` (English)
|
|
|
|
**Observer:**
|
|
- `app/Observers/UserObserver.php` (if not exists)
|
|
- Register in `AppServiceProvider` boot method
|
|
|
|
### Implementation
|
|
|
|
```php
|
|
// app/Mail/WelcomeEmail.php
|
|
class WelcomeEmail extends Mailable implements ShouldQueue
|
|
{
|
|
use Queueable, SerializesModels;
|
|
|
|
public function __construct(
|
|
public User $user,
|
|
public string $password
|
|
) {}
|
|
|
|
public function envelope(): Envelope
|
|
{
|
|
return new Envelope(
|
|
subject: $this->user->preferred_language === 'en'
|
|
? 'Welcome to Libra Law Firm'
|
|
: 'مرحباً بك في مكتب ليبرا للمحاماة',
|
|
);
|
|
}
|
|
|
|
public function content(): Content
|
|
{
|
|
return new Content(
|
|
markdown: 'emails.welcome.' . ($this->user->preferred_language ?? 'ar'),
|
|
with: [
|
|
'loginUrl' => route('login'),
|
|
'password' => $this->password,
|
|
],
|
|
);
|
|
}
|
|
}
|
|
```
|
|
|
|
```php
|
|
// app/Observers/UserObserver.php
|
|
class UserObserver
|
|
{
|
|
public function created(User $user): void
|
|
{
|
|
// Only send if password was set (admin creation scenario)
|
|
// The plain password must be passed from the creation context
|
|
}
|
|
}
|
|
```
|
|
|
|
### Trigger Mechanism
|
|
The welcome email requires the plain-text password, which is only available at creation time. Options:
|
|
1. **Recommended:** Dispatch from the admin user creation action/controller after creating user
|
|
2. Alternative: Use a custom event `UserCreatedWithPassword` that carries both user and password
|
|
|
|
## Edge Cases
|
|
|
|
- **Missing `preferred_language`:** Default to Arabic ('ar')
|
|
- **Email delivery failure:** Handled by queue retry mechanism (Story 8.1)
|
|
- **Password in email:** This is intentional for admin-created accounts; password is shown once
|
|
|
|
## Testing Requirements
|
|
|
|
### Unit Tests
|
|
- [x] `WelcomeEmail` mailable contains correct subject for Arabic user
|
|
- [x] `WelcomeEmail` mailable contains correct subject for English user
|
|
- [x] `WelcomeEmail` uses correct template based on language
|
|
- [x] Default language is Arabic when `preferred_language` is null
|
|
|
|
### Feature Tests
|
|
- [x] Email is queued when user is created
|
|
- [x] Arabic template renders without errors
|
|
- [x] English template renders without errors
|
|
- [x] Email contains login URL
|
|
- [x] Email contains user's password
|
|
- [x] Email contains user's name
|
|
|
|
### Test Example
|
|
```php
|
|
use App\Mail\WelcomeEmail;
|
|
use App\Models\User;
|
|
use Illuminate\Support\Facades\Mail;
|
|
|
|
test('welcome email is sent when user is created', function () {
|
|
Mail::fake();
|
|
|
|
$user = User::factory()->create(['preferred_language' => 'ar']);
|
|
|
|
Mail::to($user)->send(new WelcomeEmail($user, 'test-password'));
|
|
|
|
Mail::assertQueued(WelcomeEmail::class, function ($mail) use ($user) {
|
|
return $mail->user->id === $user->id;
|
|
});
|
|
});
|
|
|
|
test('welcome email uses arabic template by default', function () {
|
|
$user = User::factory()->create(['preferred_language' => null]);
|
|
$mailable = new WelcomeEmail($user, 'password123');
|
|
|
|
$mailable->assertSeeInHtml('تسجيل الدخول');
|
|
});
|
|
```
|
|
|
|

## QA Results
|
|
|
|
### Review Date: 2025-12-29
|
|
|
|
### Reviewed By: Quinn (Test Architect)
|
|
|
|
### Code Quality Assessment
|
|
|
|
**Overall: Excellent implementation.** The story has been implemented cleanly and professionally following Laravel best practices.
|
|
|
|
**Key Strengths:**
|
|
- Proper separation of concerns: `WelcomeEmail` mailable handles email content/structure, `WelcomeAccountNotification` wraps it for notification delivery
|
|
- Both classes implement `ShouldQueue` ensuring async delivery and not blocking user creation
|
|
- Locale handling is correctly defaulting to Arabic ('ar') when `preferred_language` is null
|
|
- Templates use correct RTL support for Arabic and appropriate branding
|
|
- Integration with admin client creation flows is clean and well-tested
|
|
|
|
**Code Architecture:**
|
|
- `WelcomeEmail.php:24` - Locale set in constructor, ensuring consistent serialization for queued jobs
|
|
- `WelcomeEmail.php:32,46` - Defensive null-coalescing ensures default language even if property lost during queue serialization
|
|
- `WelcomeAccountNotification.php:34-38` - Returns mailable directly to leverage Laravel's mailable-as-notification pattern
|
|
|
|

### Security Review
|
|
|
|
**Status: PASS**
|
|
|
|
- Plain-text password in email is intentional per story requirements (admin-created accounts, password shown once)
|
|
- Password is captured at creation time, not retrieved from database
|
|
- Email is queued, reducing attack surface on synchronous operations
|
|
- No sensitive data logged in AdminLog (password excluded from `new_values`)
|
|
|
|
### Performance Considerations
|
|
|
|
**Status: PASS**
|
|
|
|
- Email is queued via `ShouldQueue` - no blocking on HTTP request
|
|
- Uses Laravel's built-in queue serialization
|
|
- Template rendering is lightweight markdown
|
|
|
|
