DoctrineCacheBundle

Setup and Configuration

Doctrine cache for Symfony is maintained in the DoctrineCacheBundle. The bundle uses external Doctrine Cache library.

Follow these steps to install the bundle and the library in the Symfony Standard edition. Add the following to your composer.json file:

1
{
    "require": {
        "doctrine/doctrine-cache-bundle": "1.0.*"
    }
}

Update the vendor libraries:

$ php composer.phar update doctrine/doctrine-cache-bundle

If everything worked, the DoctrineCacheBundle can now be found at vendor/doctrine/doctrine-cache-bundle.

Finally, register the Bundle DoctrineCacheBundle in app/AppKernel.php.

1
// ...
public function registerBundles()
{
    $bundles = array(
        // ...

        new Doctrine\Bundle\DoctrineCacheBundle\DoctrineCacheBundle(),
    );

    // ...
}

# app/config/config.yml
doctrine:
    orm:
        metadata_cache_driver:
            # will load doctrine_cache.providers.metadata_cache_driver
            cache_provider: metadata_cache_driver
        query_cache_driver:
            cache_provider: query_cache_driver
        result_cache_driver:
            # if you're using a version < 1.3 of the DoctrineBundle
            # you can use the "service" type
            type: service
            id: doctrine_cache.providers.result_cache_driver

doctrine_cache:
    providers:
        metadata_cache_driver:
            type: apc
        query_cache_driver:
            type: apc
        result_cache_driver:
