How to implement solution with php 8.1 and symfony cache not invalidating on doctrine entity updates
Does anyone know how to I'm experiencing an scenario with Symfony's cache not invalidating correctly when updating Doctrine entities in PHP 8.1. After updating an entity, I expect the cache to reflect the latest data, but it seems to hold onto stale data, causing inconsistencies in my application. I've implemented a caching strategy using Symfony's `Cache` component and set up a cache pool in my `services.yaml` as follows: ```yaml framework: cache: pools: my_cache_pool: adapter: cache.adapter.filesystem ``` In my controller, I update an entity and then attempt to clear the cache: ```php public function updateEntity(EntityManagerInterface $em, $id, Request $request) { $entity = $em->getRepository(MyEntity::class)->find($id); if (!$entity) { throw $this->createNotFoundException('Entity not found'); } // ... Update entity properties based on request data $em->flush(); // Clear the cache $this->cache->delete('my_entity_'.$id); } ``` However, when I retrieve the entity after the update, I still see the old values. I’ve verified that the cache key is correct and that the entity is being updated in the database. I've also tried using the `invalidateTags()` method based on the suggestions found in the Symfony documentation, but it doesn't seem to make a difference: ```php $this->cache->invalidateTags(['my_entity_'.$id]); ``` This is a critical scenario for my application, and any guidance on ensuring that the cache invalidation works correctly would be greatly appreciated. Additionally, I would like to confirm if there are any known issues with cache invalidation in Symfony 5.4 when using PHP 8.1, or any best practices I might be missing while setting up cache for Doctrine entities. I'm working on a mobile app that needs to handle this.
