Symfony2 - bundle中的doctrine连接配置

Question

I have project which uses my additional bundle. This bundle connects to other database and I need configuration for another database.

I want to have this connections in 2 config files.

main config:

# ROOT/app/config/config.yml:
doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   "%database_driver%"
                host:     "%database_host%"
                port:     "%database_port%"
                dbname:   "%database_name%"
                user:     "%database_user%"
                password: "%database_password%"
                charset:  UTF8

bundle config:

# src/SecondBundle/Resources/config/config.yml
doctrine:
    dbal:
        connections:
            secondBundle:
                driver:   "%secondBundle.database_driver%"
                host:     "%secondBundle.database_host%"
                port:     "%secondBundle.database_port%"
                dbname:   "%secondBundle.database_name%"
                user:     "%secondBundle.database_user%"
                password: "%secondBundle.database_password%"
                charset:  UTF8

Bundle Extension file:

class SecondBundleExtension extends Extension
{
    /**
     * {@inheritdoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('config.yml');
    }
}

In my opinion everything looks OK, but when I'm trying to run this I have communicate:

There is no extension able to load the configuration for "doctrine"

Answer 1

You can declare the second driver that is specific to your bundle (named SecondBundle in your example using the PrependExtensionInterface .

Rename first your config.yml file in SecondBundle to doctrine.yml (or any other name that is not config.yml ).

Change now your SecondBundleExtension class like this:

use Symfony\Component\DependencyInjection\Exception\InvalidArgumentException;
use Symfony\Component\DependencyInjection\Extension\PrependExtensionInterface;
use Symfony\Component\Yaml\Exception\ParseException;
use Symfony\Component\Yaml\Parser as YamlParser;
// ...

class SecondBundleExtension extends Extension implements PrependExtensionInterface
{
    public function load(array $configs, ContainerBuilder $container)
    {
        // ...
    }

    public function prepend(ContainerBuilder $container)
    {    
        $yamlParser = new YamlParser();

        try {
            $doctrineConfig = $yamlParser->parse(
                file_get_contents(__DIR__.'/../Resources/config/doctrine.yml')
            );
        } catch (ParseException $e) {
            throw new InvalidArgumentException(sprintf('The file "%s" does not contain valid YAML.', $file), 0, $e);
        }

        $container->prependExtensionConfig('doctrine', $doctrineConfig['doctrine']);
    }
}

Your secondBundle connection will now be automatically registered when you enable your bundle.

You can add your extra config to the imports in your app/config/config.yml so that it is merged into the full config .

app/config/config.yml

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: '@SecondBundle/Resources/config/config.yml' }

Updated with quotes due to the fact that a non-quoted string cannot start with @ or ` (reserved) nor with a scalar indicator (| or >) since version 3.0.
