I try setup custom router loader like here
http://symfony.com/doc/current/cookbook/routing/custom_route_loader.html
i want add dynamic parameter for all routes (parameter from session)
this is my code
namespace Mea\Crm4Bundle\Routing;
use Mea\Crm4Bundle\Entity\Application;
use Symfony\Component\Config\FileLocatorInterface;
use Symfony\Component\Config\Loader\Loader;

{

'resource', 'type', 'prefix', 'pattern', 'path', 'host', 'schemes', 'methods', 'defaults', 'requirements', 'options', 'condition',
);

*/
public function __construct(FileLocatorInterface $locator, AnnotationClassLoader $annotationClassLoader, Session $session)
{
$this->locator = $locator;
$this->annotationClassLoader = $annotationClassLoader;
$this->session = $session;
}
public function load($file, $type = null)
{
$appId = $this->session->get(
Application::CRM_APP_ID_SESSION
);
$path = $this->locator->locate($file);
if (!stream_is_local($path)) {
throw new \InvalidArgumentException(sprintf('This is not a local file "%s".', $path));
}
if (!file_exists($path)) {

}
if (null === $this->yamlParser) {
$this->yamlParser = new YamlParser();
}
try {
$parsedConfig = $this->yamlParser->parse(file_get_contents($path));
} catch (ParseException $e) {
throw new \InvalidArgumentException(sprintf('The file "%s" does not contain valid YAML.', $path), 0, $e);
}
$collection = new RouteCollection();
$collection->addResource(new FileResource($path));
// empty file

return $collection;
}
// not an array

}

$config['defaults']['_applicationid']=$appId;
if (isset($config['pattern'])) {

}
@trigger_error(sprintf('The "pattern" option in file "%s" is deprecated since version 2.2 and will be removed in 3.0. Use the "path" option in the route definition instead.', $path), E_USER_DEPRECATED);
$config['path'] = $config['pattern'];
unset($config['pattern']);
}
$this->validate($config, $name, $path);
if (isset($config['resource'])) {
$this->parseImport($collection, $config, $path, $file);
} else {
$this->parseRoute($collection, $name, $config, $path);
}
}
return $collection;
}
public function supports($resource, $type = null)
{
return 'crmapp' === $type;
}
}
here is routing.yml
mea_crm:
resource: @MeaCrm4Bundle/Resources/config/routing.yml
type: crmapp
prefix: /{_applicationid}
defaults: { _applicationid: 5 }
here is services.yml
app.routing_loader:
class: Mea\Crm4Bundle\Routing\AppLoader
arguments: [@file_locator, @sensio_framework_extra.routing.loader.annot_class,@session]
tags:
- { name: routing.loader }
This loader is fired once if i remove cache. So i think this is not what i need. How i can override router or in other way - i want setup _aplication id default value from session.
UPDATE 1
i setup router
here is working method
class RouteGenerator extends UrlGenerator
public function doGenerate($variables, $defaults, $requirements, $tokens, $parameters, $name, $referenceType, $hostTokens, array $requiredSchemes = array()){
if(!isset($parameters[MeaCrm4Bundle::CRM_APP_SWITCH_PARAMETER])){
//for test
$parameters[MeaCrm4Bundle::CRM_APP_SWITCH_PARAMETER] = 1212;
}
$url = parent::doGenerate($variables, $defaults, $requirements, $tokens, $parameters, $name, $referenceType, $hostTokens, $requiredSchemes);
return $url;
}
when i add to parameters.yml
router.options.generator_base_class: Mea\Crm4Bundle\Routing\RouteGenerator
i have what i want - twig, controlerrs use this router and setup my parameter. Only one - this is not service so i dont have @session What is best method to get session here ?
Thy create other class - as service ? i get example to override twig generator but there exist way to override main router by service not class ?
UPDATE 2
so i override router - but dont have session - i need like here
public function __construct(RouteCollection $routes, RequestContext $context, LoggerInterface $logger = null, Session $session)
{
$this->routes = $routes;
$this->context = $context;
$this->logger = $logger;
$this->session = $session;
}
but what now - how get session here ?
UrlGeneratorInterfaceinstead – Heah
