Symfony override configuration from the app/config.yml - symfony

Question

I have in my app/config.yml this:
# Doctrine Configuration
doctrine:
dbal:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
orm:
auto_generate_proxy_classes: %kernel.debug%
auto_mapping: true
Now I create my bundle and I want it to override some of this configuration:
doctrine:
orm:
resolve_target_entities:
Acme\UserBundle\Interfaces\User: Acme\MyBundle\Entity\User
I want to add this configuration without changing app/config.yml

Answer 1

I found solution by adding compiler pass:
class OrmResolverCompilerPass implements CompilerPassInterface
{
public function process(ContainerBuilder $container)
{
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../../Resources/config'));
$loader->load('orm.yml');
$def = $container->findDefinition('doctrine.orm.listeners.resolve_target_entity');
foreach ($container->getParameter('resolve_target_entities') as $name => $implementation) {
$def->addMethodCall('addResolveTargetEntity', array( $name, $implementation, array() ));
}
$def->addTag('doctrine.event_listener', array('event' => 'loadClassMetadata'));
}
}
And we also need to create orm.yml in the Resources/config directory inside our Bundle.
And finally register compiler pass inside controllerBundle class:
class MyAcmeBundle extends Bundle
{
public function build(ContainerBuilder $container)
{
parent::build($container);
$container->addCompilerPass(new OrmResolverCompilerPass());
}
}

You can now use PrependExtensionInterface for this:
class ThirisCartLogicCatalogExtension extends Extension implements PrependExtensionInterface
{
public function prepend(ContainerBuilder $container)
{
$config = Yaml::parse(file_get_contents(__DIR__.'/../Resources/config/config.yml'));
foreach ($config as $key => $configuration) {
$container->prependExtensionConfig($key, $configuration);
}
}
}
With this code config.yml from your bundle will be unconditionally merged into global confuguration.
Please note, that configuration file you load is not validated for syntax this way.
