Jmsserializerbundle: Detecting serializion groups in the serialize listeners

[pulse00]

When adding additional attributes in serialization listeners, is there a way to detect the active serialization groups?

[Sander-Toonen]

This is how I do it:

public function onPostSerialize(ObjectEvent $event)
{
    // Get the actual object being serialized
    $object = $event->getObject();
    $context = $event->getContext();

    // Try to get the serialization group from the context.
    try {
        $groups = $context->attributes->get('groups')->get();
    } catch (\RuntimeException $e) {
        $groups = [];
    }

    // Don't execute this listener when not in mustBeThisGroup
    if (!in_array('mustBeThisGroup', $groups)) {
        return;
    }

    // <Listener logic here>
}

But I would agree that there should be a nicer way for this.

@Sander-Toonen thanks for the feedback. i've come up with this helper in my serializers:

/**
 * @param SerializationContext $context
 * @param $group
 * @return bool
 */
private function isGroupActive(SerializationContext $context, $group)
{
    return $this->areGroupsActive($context, [$group]);
}

/**
 * @param SerializationContext $context
 * @param array $serializationGroups
 * @return bool
 */
private function areGroupsActive(SerializationContext $context, array $serializationGroups)
{
    /** @var Some $groupContext */
    $groupContext = $context->attributes->get('groups');

    if ($groupContext->isDefined()) {
        $groups = $groupContext->get();

        if (is_array($groups)) {
            foreach ($serializationGroups as $group) {
                if (in_array($group, $groups)) {
                    return true;
                }
            }
        }
    }

    return false;
}
