Symfony: Clear doctrine cache

Question

I need to clear my doctrine's cache in Symfony.

There must be some way in command line for clear the cache.

Or where should I find and delete the files belonging to cache?

rm -rf app/cache/* didn't help? – Riff

does the answer helps? if no, try clearing complete cache using app/console cache:clear – Walford

@thecatontheflat - note that the doctrine cache is often stored in apc rather than in the file system so removing the cache files would not help. – Disenable

@Walford - note that the general app/console cache:clear is only for the symfony (app) cache. I don't think it clears the doctrine cache(s). – Disenable

Answer 1

For Symfony 3+:

 php bin/console

will list all commands, the following are relevant for cache:

 php bin/console doctrine:cache:clear-metadata 
 php bin/console doctrine:cache:clear-query  
 php bin/console doctrine:cache:clear-result

---

Before Symfony 3:

app/console

will list how you can do it

 app/console doctrine:cache:clear-metadata 
 app/console doctrine:cache:clear-query  
 app/console doctrine:cache:clear-result 

Walford

By the way, if you are using mongodb for example you can do 'app/console doctrine:mongodb:cache:clear-metadata' or just do 'app/console doctrine' and you will see all available options – Meditate

Note that you can always use app/console list to show all commands or app/console list doctrine to just show commands in the 'doctrine' namespace – Disenable

I tried doctrine:cache:clear-result in prod environment. It is not working. I also tried bin/doctrine orm:clear-cache:result. It doesn't work either. I'm using memcache. – Lvov

Answer 2

If you want to do it within your code (from Doctrine's documentation) :

If you simply want to delete all cache entries you can do so with the deleteAll() method.

$cacheDriver = new \Doctrine\Common\Cache\ArrayCache();
$deleted = $cacheDriver->deleteAll();

What's the difference to cache flushing? – Wyon

This code creates a new cache driver. It should utilize the current QueryCacheProfile or result cache implementation from the configuration. It will not magically clear cache in your application if use use e.g. Redis or Memcached. – Alexia

Answer 3

In case you use APC, you could also just call the code

<?php
$deleted = apc_clear_cache() && apc_clear_cache('user');

in a php page on the same server. This is what deleteAll() method in Antho's answer does, but you do not depend on the Doctrine Classes. Btw: the complete cache will be flushed - just in case you use it for non-Doctrine stuff.

Answer 4

I thought I was going crazy with doctrine results caching - in the end I had to restart memcached.

how to restart memcached? – Topheavy

Answer 5

I know the title of this post says Symfony 2, but for those of you coming from google, if you have Symfony 3+ its gonna be:

bin/console

As opposed to:

app/console

Answer 6

Maybe is a little late for this, but in my case, doctrine didn't generate the proxy classes in production, for that I change the auto_generate_proxy_classes to true:

#symfony2&3 app/config/config.yml
#symfony4 config/packages/doctrine.yaml (by default true since 4.2)

doctrine:
    orm:
        auto_generate_proxy_classes: true #"%kernel.debug%"

What do these proxy classes do? – Talanta

Answer 7

Maybe someone searching
Symfony 6.2+

public function __construct(..., private KernelInterface $kernel

And

$this->kernel->shutdown(); //RESET ALL

You running Multiple entities and You managed connection with Sessions

/** @var SiteService $siteService */
$siteService = $this->kernel->getContainer()->get(SiteService::class); //Important kernel->getContainer()
/** @var Site[] $sites */
$sites = $siteService->repository->getByInstalledSites();

foreach ($sites as $site) {
    dump('Domain:'. $site->getDomain());
    $session = new Session();
    $session->set('db_user', $site->getUser());
    $session->set('db_password', $this->getDecryptPassword($site->getPassword()));
    $session->set('db_name', $site->getDatabaseName())
    
    $user = $this->userService->getById(1);

    dump($user);
    //what you want to do ...

    $this->kernel->shutdown(); //Running All bundles shutdown and container set null        
    $this->kernel->boot(); // services_resetter->reset and preboot -> loading bundles&Containers and all bundles set container & run boot
}

Answer 8

In the hopes that this might help someone coming here with Doctrine caching issues.

I had an issue with the OrderBy attribute and the PostLoad event not seeming to fire. The problem was that the entity was already loaded into the EntityManager (from when I created it). Because it was already loaded, subsequent calls to get it went to memory/cache and the expected events wouldn't get fired.

To fix, you can clear the entity out of the EntityManager. Then when you get the entity, the PostLoad callback, OrderBy, etc will fire. You can clear the entity out of the EntityManager like so:

$this->em->clear(MyEntity::class);
