Is it possible to add custom routes during compilation passes?

Question

I prepare external bundle and I would like to add some routes during compilation passes. Routes will be created on the main app/config/config.yml settings.

I was trying to get router from ContainerBuilder in my CustomCompilerPass via:

$definition = $container->getDefinition('router');

, but I got The service definition "router" does not exist .

Is it possible to add custom routes during compilation passes?

Answer 1

There's no way to add routes at compiler passes.
In order to dynamicly load routes (aware of container parameters) I'd use a custom route loader as given in my previous example

class MyLoader extends Loader
{
    protected $params;

    public function __construct($params)
    {
        $this->params = $params;
    }

    public function supports($resource, $type = null)
    {
        return $type === 'custom' && $this->params == 'YourLogic';
    }

    public function load($resource, $type = null)
    {
        // This method will only be called if it suits the parameters
        $routes   = new RouteCollection;
        $resource = '@AcmeFooBundle/Resources/config/dynamic_routing.yml';
        $type     = 'yaml';

        $routes->addCollection($this->import($resource, $type));

        return $routes;
    }
}

routing.yml

_custom_routes:
    resource: .
    type:     custom

Answer 2

router is an alias, not a service. To get that from a ContainerBuilder , use ContainerBuilder::getAlias . To get the service ID, you need to cast that object to a string: (string) $container->getAlias('router') . Now, you can use that ID to get the service: $container->getDefinition($container->getAlias('router')) . And then you get the Service which you can modify to add routes.

BTW, I'm not sure if this is really the thing you want. What about using the CmfRoutingBundle . Then, you use the Chain Router, so you can use both the Symfony2 router and the DynamicRouter. The DynamicRouter can be used with a custom route provider, in which you return the routes you want (you can get them from every resource you want).
