Symfony2 Templating without request

Question

I\'m trying to send an email from a ContainerAwareCommand in Symfony2. But I get this exception when the email template is render by:

$body = $this-         


        

Answer 1

Following BetaRide's answer put me on the right track but that wasn't sufficient. Then it was complaining: "Unable to generate a URL for the named route "" as such route does not exist."

To create a valid request I've modified it to request the root of the project like so:

$request = new Request();
$request->create('/');
$this->container->enterScope('request');
$this->container->set('request', $request, 'request');

You might need to call a different route (secured root?), root worked for me just fine.

Bonus addition:

I had to do so much templating/routing in cli through Symfony2 commands that I've updated the initializeContainer() method in AppKernel. It creates a route to the root of the site, sets the router context and fakes a user login:

protected function initializeContainer()
{
    parent::initializeContainer();
    if (PHP_SAPI == 'cli') {

        $container = $this->getContainer();

        /**
         * Fake request to home page for cli router.
         * Need to set router base url to request uri because when request object
         * is created it perceives the "/portal" part as path info only, not base
         * url and thus router will not include it in the generated url's.
         */
        $request = Request::create($container->getParameter('domain'));
        $container->enterScope('request');
        $container->set('request', $request, 'request');
        $context = new RequestContext();
        $context->fromRequest($request);
        $container->get('router')->setContext($context);
        $container->get('router')->getContext()->setBaseUrl($request->getRequestUri());

        /**
         * Fake admin user login for cli. Try database read,
         * gracefully print error message if failed and continue.
         * Continue mainly for doctrine:fixture:load when db still empty.
         */
        try {
            $user = $container->get('fos_user.user_manager')->findUserByUsername('admin');
            if ($user !== null) {
                $token = $token = new UsernamePasswordToken($user, null, 'main', $user->getRoles());
                $this->getContainer()->get('security.token_storage')->setToken($token);
            }
        } catch (\Exception $e) {
            echo "Fake Admin user login failed.\n";
        }
    }
}

You might not need the last $container->get('router')->getContext()->setBaseUrl($request->getRequestUri()); part, but I had to do it because my site root was at domain.com/siteroot/ and the router was stripping /siteroot/ away for url generation.
