Symfony 2 ParamConverter不工作

Question

I want to use the ParamConverter in symfony2 but i keeps return exceptions.

I have this code :

/**
 * @Route("/")
 * @Route("/{_locale}")
 * @ParamConverter("domain", class="ProdacomMainBundle:PdbDomain")
 * @Template("ProdacomMainBundle:Main:index.html.twig, vars={"domain"})
 */
public function indexAction(PdbDomain $domain) {

}

The error it keeps returning :

    FileLoaderLoadException: Cannot import resource "C:\htdocs\domeinbeheer\src\Prodacom\MainBundle/Controller/" from "C:/htdocs/domeinbeheer/app/configouting.yml". ([Syntax Error] Expected Doctrine\Common\Annotations\DocLexer::T_CLOSE_PARENTHESIS, got 'domain' at position 177 in method Prodacom\MainBundle\Controller\MainController::indexAction().)

And this one :

    AnnotationException: [Syntax Error] Expected Doctrine\Common\Annotations\DocLexer::T_CLOSE_PARENTHESIS, got 'domain' at position 177 in method Prodacom\MainBundle\Controller\MainController::indexAction().

Any ideas ?!

Answer 1

You missed an ending quote here:

 @Template("ProdacomMainBundle:Main:index.html.twig, vars={"domain"})
                                                   ^

That's what both of those exceptions are saying.

But if you fix those you'll see that $domain cannot be populated unless you have a GET/POST parameter named domain supplying the ID.

Also if you want the domain parameter to be optional then you'll have to define your index action like this:

public function indexAction(PdbDomain $domain = null)

Otherwise you'll receive some new exceptions saying that $domain cannot be null.
