How to Add a Notification¶

The Akeneo PIM comes with a notification system.

Prerequisites¶

If you need to send a custom message for an existing notification type (like import/export, mass edit, etc.) you can go to the Inject Services step.

If you want to create your own notification type for a custom bundle, you will need to create your notification factory.

Note

This cookbook assumes that you already created a new bundle to add your new Notification. Let’s assume its namespace is Acme\CustomBundle.

Create a Notification Factory¶

First we’ll need to create the Notification Factory that will build our own notifications. This class should implement Akeneo\Platform\Bundle\NotificationBundle\Factory\NotificationFactoryInterface.

# /src/Acme/Bundle/CustomBundle/Notification/CustomNotificationFactory.php
<?php

namespace Acme\CustomBundle\Notification;

use Akeneo\Platform\Bundle\NotificationBundle\Entity\Notification
use Akeneo\Platform\Bundle\NotificationBundle\Factory\NotificationFactoryInterface;

class CustomNotificationFactory implements NotificationFactoryInterface
{
    /** @var array */
    protected $notificationTypes;

    /**
     * @param array $notificationTypes
     */
    public function __construct(array $notificationTypes)
    {
        $this->notificationTypes = $notificationTypes;
    }

    /**
     * {@inheritdoc}
     */
    public function create($object)
    {
        $notification = new Notification(); // we'll setup it just after

        return $notification;
    }

    /**
     * {@inheritdoc}
     */
    public function supports($type)
    {
        return in_array($type, $this->notificationTypes);
    }
}

Let’s take a look at what’s important here, the create method of this factory:

public function create($object)
{
    $notification = new Notification();

    $notification->setType($type);
    $notification->setMessage($message);
    $notification->setMessageParams($messageParams);
    $notification->setRoute($route);
    $notification->setRouteParams($routeParams);
    $notification->setContext($context);

    return $notification;
}

Note that $object is mixed, so feel free to give anything useful to build your notification. For instance, in our internal job notifications, we directly send the JobExecution to the create method of our Notification Factories.

Type (string)
Type of the notification. Can be success, warning or error.
Message (string)
The message to display in the notification. It can be a simple string, or a translation key, eg. pim_import_export.notification.export.success
MessageParams (array)
The message parameters to give to the translation key, if any. Eg. ['%label%' => 'Product export'] If provided, it will be passed to the message when translating it.
Route (string)
The route the user will be redirected to if the notification is clicked.

RouteParams (array)

The parameters to that given route. For example, the route of the show export profile page is:

pim_importexport_export_profile_show:
    path: /{id}
    defaults: { _controller: pim_import_export.controller.export_profile:showAction }
    requirements:
        id: \d+

The optional route parameter will be:

$route = 'pim_importexport_export_execution_show';
$routeParams = ['id' => $jobExecutionId];

Context (array)
The context allows to store some extra data in the notification, it is not displayed in the UI by default. Some important extra data you may use are:
actionType (string): this will be used to guess the icon to display on the notification

showReportButton (bool): to hide/display the “report” label on the notification

For example, the create method of the NotificationFactory for mass edit notifications looks like that:

public function create($jobExecution)
{
    $notification = new Notification();
    $type = $jobExecution->getJobInstance()->getType();
    $status = $this->getJobStatus($jobExecution);

    $notification
        ->setType($status)
        ->setMessage(sprintf('pim_mass_edit.notification.%s.%s', $type, $status))
        ->setMessageParams(['%label%' => $jobExecution->getJobInstance()->getLabel()])
        ->setRoute('pim_enrich_job_tracker_show')
        ->setRouteParams(['id' => $jobExecution->getId()])
        ->setContext(['actionType' => $type]);

    return $notification;
}

Well, now we created our very own Notification Factory, we need to register it with the proper tag:

services:
    acme_custom.notification.factory.custom_notification_factory:
        class: 'Acme\CustomBundle\Notification\CustomNotificationFactory'
        arguments:
            - ['my_custom_notification_name']
        tags:
            - { name: pim_notification.factory.notification }

With this tag we will be able to get our new factory from the dedicated registry.

Inject Services¶

Now that our Notification Factory is created and registered, we can build our own notifications!

Warning

The Notification Factory we just created is not responsible for sending notifications, only to build them. To send notification, we need to call the Notifier.

To send our notifications, we’ll need to:

Retrieve our factory with the notification factory registry (@pim_notification.registry.factory.notification)
Build the notification
Give it to the Notifier (@pim_notification.notifier) to actually notify users

So we’ll need 2 services:

services:
    acme_custom.event_subscriber.custom_subscriber:
        class: 'Acme\CustomBundle\EventSubscriber\CustomEventSubscriber'
        arguments:
            - '@pim_notification.registry.factory.notification'
            - '@pim_notification.notifier'
        tags:
            - { name: kernel.event_subscriber }

Here, we inject services in an event subscriber, but we can inject them wherever we have an action which notifies a user. Then, let’s add it to our constructor as follows:

# /src/Acme/Bundle/CustomBundle/EventSubscriber/CustomEventSubscriber.php

/** @var NotificationFactoryRegistry */
protected $factoryRegistry;

/** @var Notifier */
protected $notifier;

/**
 * @param NotificationFactoryRegistry $factoryRegistry
 * @param Notifier                    $notifier
 */
public function __construct(NotificationFactoryRegistry $factoryRegistry, Notifier $notifier)
{
    $this->factoryRegistry = $factoryRegistry;
    $this->notifier        = $notifier;
}

Notify Users¶

Now everything is plugged together, let’s send some notifications!

// 1) retrieve our factory with the notification factory registry
$factory = $this->factoryRegistry->get('my_custom_notification_name');

// 2) build the notification
$notification = $factory->create($status, $message, $messageParams, $route, $routeParams, $type);

// 3) give it to the Notifier to actually notify users
$this->notifier->notify(
    $notification,
    [$user1, $user2] // An array of users (UserInterface or just the username)
);
