Add Account token to routing - php

Question

I'm trying to add an Account to the Silex route. My goal is to have routes like:
/{_account}/{_locale}/
/{_account}/{_locale}/products
/{_account}/{_locale}/block
You can find my Code here on github. It's a small sample. I can read the account token from the request and save the Account in the AccountListener.
I try to handle the _account like _locale. Once set or updated the application don't have to bother about it. That means that the _account param will be set automatically if I call $app['url_generator']->generate('blog').
This is my current problem. I don't know how to inform the UrlGenerator to set these param.
Maybe my approach is completely wrong.
I Hope you can send me some examples or Cookbooks or somethink. Or a merge request.

Answer 1

The UrlGenerator uses parameters from the request_context (as you can see in the code) so you could set those in your listener.
src/app.php
$dispatcher = $app['dispatcher']->addSubscriber(
new AccountListener(
new AccountRepository(),
$app['request_context'],
$app['monolog']
)
);
SilexLab\Listener\AccountListener
public function __construct(
AccountProvider $accountProvider,
RequestContext $requestContext,
Logger $logger
) {
//...
$this->requestContext = $requestContext;
}
public function onKernelRequest(GetResponseEvent $event)
{
//...
$request->attributes->set('_account', $account);
$this->requestContext->setParameter('_account', $account);
}
