Notification dropdown symfony - php

Question

I have a notification icon. When user clicks on it, a dropdown appears and shows a list. I want to filter list to only show what's related to the connected user.
{% if app.user.roles[0] == "ROLE_DEVELOPPER"%}
<!-- dropdown notification message -->
<li class="dropdown">
<a title="Notifications" href="#fakelink" class="dropdown-toggle" data-toggle="dropdown">
<strong> <i class="fa fa-bell"></i></strong>
</a>
{% if notif_conges|length > 0 %}
<ul class="dropdown-menu animated half flipInX">
//this section
{% for notif_c in notif_conges %}
{% if notif_c.etat == "Acceptée" %}
<li><a>Votre demande : "{{notif_c.motif}}" Envoyée le "{{notif_c.CreatedAt|date('Y-m-d H:i:s')}}" a était traitée </a></li>
{% endif %}
{% endfor %}
</ul>
{% endif %}
</li>
{% endif %}

Answer 1

You want to filter notifications. Only notifications concerning connected users have to be displayed. You have two solutions:
The (very) bad way: Add a test in view
<ul class="dropdown-menu animated half flipInX">
//this section
{% for notif_c in notif_conges %}
{% if notif_c.etat == "Acceptée" and notif_c.user = app.user %}
<li><a>Votre demande : "{{notif_c.motif}}" Envoyée le "{{notif_c.CreatedAt|date('Y-m-d H:i:s')}}" a était traitée </a></li>
{% endif %}
{% endfor %}
</ul>
This is a bad way because you will forward all notifications to the view
The bad way: Add a filter in your controller
class YourController
{
public yourAction()
{
/** ... your code to handle notifications **/
foreach ($notifications as $notification) {
if ($notification->getUser()->getId() == $this->getUser()->getId)) {
$filteredNotification[] = $notification;
}
}
return $this->render('your_template_file', [
'notif_c' => $filteredNotifications
]);
}
}
This is still a bad way because you are retrieving all notifications from database.
The good way: Ask only the necessaries notification to your repository
Assuming, your notifications are retrieving with Doctrine, repository can filter data to only retrieve pertinent data.
class YourController
{
public yourAction()
{
/** ... your code is certainly something lke this: **/
$notificationRepository = $this->entityManager->getRepository('AppBundle:Notification');
$notifications = $notificationRepository->findAll();
render
return $this->render('your_template_file', [
'notif_c' => $notifications
]);
}
}
Replace findAll() by findBy(array $criteria) and add a criteria as first parameter:
class YourController
{
public yourAction()
{
$notificationRepository = $this->entityManager->getRepository('AppBundle:Notification');
$notifications = $notificationRepository->findBy([
'etat' => 'Acceptée',
'user' => $this->getUser(), //this could be a little different, I do not remember how to handle user in Sf2.8
]);
render
return $this->render('your_template_file', [
'notif_c' => $notifications
]);
}
}

Answer 2

Yo must use is_granted twig filter.
You can specify the user role that you one but IS_AUTHENTICATED_REMEMBERED role is given to all users who are logged in.
{% is_granted('IS_AUTHENTICATED_REMEMBERED') %}
<!-- dropdown notification message -->
...
{% endif %}
