Using the registry in your bundle¶

We will to show you how to set up the sylius registry. In this example, we will register two price calculators.

<!-- Resources/config/services.xml -->

<?xml version="1.0" ?>

<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
    <parameters>
        <parameter key="app.price.calculator.registry.class">App\Component\Registry\ServiceRegistry</parameter>
        <parameter key="app.price.calculator.interface">App\Bundle\MyBundle\PriceCalculatorInterface</parameter>
    </parameters>

    <services>
        <!-- You need to declare the registry as a service, it expect as argument the type of object that you want to register -->
        <service id="app.price.calculator.registry" class="%app.price.calculator.registry.class%">
            <argument>%app.price.calculator.interface%</argument>
        </service>

        <!-- Don't forget that a registry don't create object. You need to create them before and register them into the registry after -->
        <service id="app.price.calculator.default" class="...">
        <service id="app.price.calculator.custom" class="...">
    </services>
</container>

namespace App\Bundle\MyBundle\DependencyInjection\Compiler;

class RegisterCalculatorServicePass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        // You can check if your registry is defined
        if (!$container->hasDefinition('app.price.calculator.registry')) {
            return;
        }

        $registryDefinition = $container->getDefinition('app.price.calculator.registry');

        // You can register your services like this
        $registryDefinition->addMethodCall(
            'register',
            array(
                'default',
                new Reference('app.price.calculator.default'),
            )
        );

        $registryDefinition->addMethodCall(
            'register',
            array(
                'custom',
                new Reference('app.price.calculator.default'),
            )
        );
    }
}

Finally, you need to register your custom pass with the container

namespace App\Bundle\MyBundle;

class AppMyBundleBundle extends Bundle
{
    public function build(ContainerBuilder $container)
    {
        parent::build($container);

        $container->addCompilerPass(new RegisterServicePass());
    }
}
