Custom Route-Generator

The RouteBundle enables you to define custom route generators. These generators will be called every time you create or update a route for the given entity. For each entity you can define which generator will be used.

The following example will generate a route by using the core route generator, but you can define route schemas for each entity type.

<?php

class RouteGenerator implements RouteGeneratorInterface
{
    /**
     * @var RouteGeneratorInterface
     */
    private $routeGenerator;

    /**
     * {@inheritdoc}
     */
    public function __construct(RouteGeneratorInterface $routeGenerator)
    {
        $this->routeGenerator = $routeGenerator;
    }

    /**
     * {@inheritdoc}
     */
    public function generate($entity, array $options)
    {
        $type = $entity->getType();

        if (!array_key_exists($type, $options)) {
            throw new \Exception(sprintf('Route-schema for type "%s" not configured!', $type));
        }

        return $this->routeGenerator->generate($entity, ['route_schema' => $options[$type]]);
    }

    /**
     * {@inheritdoc}
     */
    public function getOptionsResolver(array $options)
    {
        // allow all options.
        return (new OptionsResolver())->setDefined(array_keys($options));
    }
}

Register this as a service with the tag sulu.route_generator (with alias custom for example) and use this alias in the configuration:

sulu_route:
    mappings:
        AppBundle\Entity\Recipe:
            generator: schema
            options:
                route_schema: /{translator.trans('recipe')}/{object.getTitle()}
        AppBundle\Entity\Example:
            generator: custom
            options:
                type1: /example/{object.getName()}
                type2: /example/{object.getTitle()}
