DoctrineCacheBundle
===================
Since the version 1.3 of DoctrineBundle the DoctrineCacheBundle is included by default.
The DoctrineCacheBundle is used to allow different systems of cache in your application using the `Doctrine Cache`_ library.
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:
.. code-block:: json
{
"require": {
"doctrine/doctrine-cache-bundle": "1.0.*"
}
}
Update the vendor libraries:
.. code-block:: bash
$ php composer.phar update doctrine/doctrine-cache-bundle
If everything worked, the ``DoctrineCacheBundle`` can now be found
at ``vendor/doctrine/doctrine-cache-bundle``.
.. note::
``DoctrineCacheBundle`` installs
`Doctrine Cache`_ library. The library can be found
at ``vendor/doctrine/cache``.
Finally, register the Bundle ``DoctrineCacheBundle`` in ``app/AppKernel.php``.
.. code-block:: php
// ...
public function registerBundles()
{
$bundles = array(
// ...
new Doctrine\Bundle\DoctrineCacheBundle\DoctrineCacheBundle(),
);
// ...
}
ORM caching configuration
-------------------------
Some configurations of the ORM can use cache to prevent an excessive number of requests, read the `Caching Drivers`_.
.. code-block:: yaml
# 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:
type: apc
