I’m trying to build a preUpdate, I was doing it with a postUpdate but I didn’t contemplate the fact that I was changing whenever an edit of that entity was being made, no matter the field… so I read I should use preUpdate instead…<\/p>\n

This is my preUpdate Listener:<\/p>\n

namespace Prizes\\PrizesBundle\\EventListener;\n\nuse Doctrine\\ORM\\Event\\LifecycleEventArgs;\nuse Prizes\\PrizesBundle\\Entity\\Prize;\nuse Prizes\\CatalogBundle\\Entity\\CatalogHasPrize as CHP;\n\n\/**\n * Description of DeactivatePrizesInCatalog\n *\n * @author Victoria Noguera\n * Desactiva premios en catalogos cuando se desactiven en el prize central.\n *\/\n\/**\n * @ORM\\Entity\n * @ORM\\HasLifecycleCallbacks\n *\/\nclass DeactivatePrizesInCatalog {\n\/**\n     * @ORM\\PrePersist()\n     * @ORM\\PreUpdate()\n     *\/\n    public function preUpdate(LifecycleEventArgs $args) {\n       $entity = $args->getEntity();\n        $entityManager = $args->getEntity\n\nManager();\n    if ($entity instanceof Prize) {\n        if ($args->hasChangedField('status')) {\n            $status_new = $args->getNewValue('status');\n            if ($status_new->getName() == \"Inactive\") {\n                $statusinactive = $entityManager->getRepository('AppStatusBundle:Status')->find(8);\n                $q = $entityManager->createQuery(\"UPDATE CatalogBundle:CatalogHasPrize c SET c.status = :statusid WHERE c.status = 7 AND c.prize = :prizeid\")\n                        ->setParameters(array('statusid' => $statusinactive, 'prizeid' => $entity->getId()));\n                $rs = $q->getResult();\n            } else if ($status_new->getName() == \"Active\") {\n                $statusinactive = $entityManager->getRepository('AppStatusBundle:Status')->find(7);\n                $q = $entityManager->createQuery(\"UPDATE CatalogBundle:CatalogHasPrize c SET c.status = :statusid WHERE c.status = 8 AND c.prize = :prizeid\")\n                        ->setParameters(array('statusid' => $statusinactive, 'prizeid' => $entity->getId()));\n                $rs = $q->getResult();\n            }\n        }\n    }\n}\n\n}\n<\/code><\/pre>\n
and this is the way i’m doing it on the config.yml file (I just read it goes in a services.yml, but i’ll change it later)<\/p>\n
services:\n    preupdate.listener:\n        class: Prizes\\PrizesBundle\\EventListener\\DeactivatePrizesInCatalog\n        tags: \n             - { name: doctrine.event_listener , event: preUpdate }\n<\/code><\/pre>\n
however, when I do this, my project goes from fully functional to 503 service unavailable. Even if I just write public function preUpdate(LifecycleEventArgs $args) { }<\/code> it crashes, I’m assuming a configuration issue, but I have no idea what I’m doing wrong.<\/p>\n
I’d appreciate any help offered. Thank you<\/p>\n","protected":false},"excerpt":{"rendered":"
