Getting Started

Minimal Setup

Installation

composer require div-looper/inbox-bundle

Add to config/bundles.php:

return [
    // ...
    DivLooper\InboxBundle\DivLooperInboxBundle::class => ['all' => true],
];

Database Migration Run migrations to create the required tables:

php bin/console doctrine:migrations:diff
php bin/console doctrine:migrations:migrate

First Use Case Create a message entity via the bundle’s service:

use DivLooper\InboxBundle\Entity\Message;

$message = new Message();
$message->setSender('user@example.com');
$message->setSubject('Hello!');
$message->setBody('This is a test message.');
$message->setRecipient($userEntity); // User entity from your app

$em = $this->getDoctrine()->getManager();
$em->persist($message);
$em->flush();

Viewing Messages Use the bundle’s controller to fetch messages for a user:

$messages = $this->get('div_looper_inbox.message_manager')->getMessagesForUser($user);

Implementation Patterns

Core Workflows

Sending Messages

Programmatic Sending Use the MessageManager service to send messages programmatically:

$manager = $this->get('div_looper_inbox.message_manager');
$manager->sendMessage($recipientUser, 'subject', 'body', $senderUser);

Event-Based Sending Trigger message creation via Symfony events (e.g., after user registration):

// In your event subscriber
$message = new Message();
$message->setSender($this->getUser());
$message->setSubject('Welcome!');
$message->setBody('Thanks for registering.');
$message->setRecipient($user);

$em->persist($message);

Reading and Marking Messages

Fetch unread messages for a user:

$unreadMessages = $manager->getUnreadMessagesForUser($user);

Mark messages as read:

$manager->markMessagesAsRead($messages);

Integration with User Authentication

Middleware/Guard Integration Attach the bundle’s logic to your authentication system (e.g., FOSUserBundle):
```
// In a controller or service
$user = $this->getUser();
$messages = $manager->getMessagesForUser($user);
```

Twig Integration Pass messages to Twig templates:

{% for message in messages %}
    <div class="message">
        <h3>{{ message.subject }}</h3>
        <p>{{ message.body }}</p>
        <small>From: {{ message.sender.email }}</small>
    </div>
{% endfor %}

Customizing Message Types

Extend the Message entity to add custom fields:

namespace App\Entity;

use DivLooper\InboxBundle\Entity\Message as BaseMessage;

class CustomMessage extends BaseMessage
{
    private $customField;

    // Getters/setters
}

Override the bundle’s services via configuration:

# config/packages/div_looper_inbox.yaml
div_looper_inbox:
    message_class: App\Entity\CustomMessage

Gotchas and Tips

Pitfalls

Database Schema Assumptions
- The bundle assumes standard Doctrine entity relationships. If your User entity uses non-standard field names (e.g., email_address instead of email), override the Message entity or use a custom repository.
- Fix: Extend the Message entity and update the recipient/sender mappings:
```
/**
 * @ORM\ManyToOne(targetEntity="App\Entity\User", inversedBy="messages")
 * @ORM\JoinColumn(name="recipient_id", referencedColumnName="id")
 */
private $recipient;
```
Missing Event Listeners
- The bundle does not include built-in event listeners for actions like "message sent" or "message read." You must manually trigger events or log actions.
- Tip: Create a custom event subscriber:
```
use DivLooper\InboxBundle\Entity\Message;
use Doctrine\ORM\Event\LifecycleEventArgs;

public function postPersist(Message $message, LifecycleEventArgs $args)
{
    // Log or dispatch an event
}
```
Permission Handling
- The bundle does not enforce access control. Ensure your controllers validate user permissions before fetching/sending messages.
- Example:
```
if (!$this->get('security.authorization_checker')->isGranted('ROLE_USER')) {
    throw $this->createAccessDeniedException();
}
```

Performance with Large Datasets

Fetching all messages for a user without pagination can be slow. Always paginate results:

$paginator = $this->get('knp_paginator');
$messages = $paginator->paginate(
    $manager->getMessagesForUser($user),
    $pageNumber,
    20 // items per page
);

Debugging Tips

Enable SQL Logging Add this to config/packages/dev/doctrine.yaml to debug queries:
```
doctrine:
    dbal:
        logging: true
        profiling: true
```
Check Entity Relationships If messages aren’t saving/loading correctly, verify the recipient/sender relationships in the Message entity. Use:
```
php bin/console doctrine:schema:validate
```
Clear Cache After Customization After extending the Message entity or overriding services, clear the cache:
```
php bin/console cache:clear
```

Extension Points

Custom Message Types

Create a trait or abstract class for reusable message logic:

trait NotifiableMessage
{
    public function isUrgent(): bool
    {
        return strpos($this->subject, 'URGENT') !== false;
    }
}

Add Attachments Extend the Message entity to support file attachments:

/**
 * @ORM\OneToMany(targetEntity="App\Entity\MessageAttachment", mappedBy="message", cascade={"persist", "remove"})
 */
private $attachments;

Override Templates The bundle likely uses Twig templates for emails/notifications. Override them in templates/DivLooperInboxBundle/:
```
{# templates/DivLooperInboxBundle/Messages/message.html.twig #}
Custom message template here.
```

API Integration Expose message endpoints via API Platform or FOSRestBundle:

# config/api_platform/resources.yaml
resources:
    DivLooper\InboxBundle\Entity\Message:
        collectionOperations:
            get:
                method: GET
                path: /messages
                security: "is_granted('ROLE_USER')"
