Ahoj, prosím, jak tohle správně použít? Zaregistroval jsem jako service do config.neon: - UrlGenerator a pak volám v konstruktoru modelu public function __construct(Nette\Http\Request $request, UrlGenerator $urlGenerator) {

Dostávám hlášku Service '84_UrlGenerator': Service of type Nette\Http\Url needed by UrlGenerator::__construct() not found. Did you register it in configuration file? Dělám něco blbě? Nette\Http\Request jsem taky nemusel registrovat a ten funguje.... Díky
