[SOLVED] How can I use the a cache manager in Symfony?

How can I use the a cache manager in Symfony?

I my contoller I try to clear the cache when updating a page

protected function mapDataToEntity(array $data, Project $entity): void{
    
    $entity->setName($data['name']);

    $cacheManager = $this->get('sulu_http_cache.cache_manager');
    $cacheManager->invalidatePath($path, $headers);
}

I get the error message:

Attempted to call an undefined method named "get" of class "App\Controller\Admin\ProjectController". Did you mean to call e.g. "cgetAction", "getAction", "getLocale" or "getSecurityContext"?

Solution

You should autowire your cache manager instead of trying to access it from the container.

private CacheManager $cacheManager;

public function __construct(CacheManager $cacheManager)
{
    $this->cacheManager = $cacheManager;
}

And use it in your method:

$this->cacheManager->invalidatePath($path, $headers);
