Symfony2服务无法找到模板

Question

I've just pulled an all-nighter trying to get this to work, and I'm probably missing something foolish, but help me out.

I have a symfony2 service which sends emails. I have injected the @templating service into my service's constructor like so:

services.yml

order_service:
    class: AppBundle\Services\OrderService
    arguments: [ "@doctrine.orm.entity_manager", "@mailer", "@templating" ]

OrderService.php

/**
 * @var EntityManager
 */
protected $em;

protected $twig;

protected $mailer;    

public function __construct(EntityManager $_entityManager, $_mailer, $_twig)
{
    $this->em = $_entityManager;
    $this->mailer = $_mailer;
    $this->twig = $_twig;
}

I have my templates located in AppBundle/Resources/views/Emails . Further down in my service is the function that tries to send emails.

protected function send_emails($vendors, $order)
{
    $customer = $order->getCustInfo();

    // Send email(s) to customer
    foreach ($order->getVouchers() as $voucher)
    {
        $message = \Swift_Message::newInstance()
            ->setSubject('Voucher # ' . $voucher->getId())
            ->setFrom('from_address@foobar.com')
            ->setTo($customer->email)
            ->setBody($this->twig->render(
                'Emails/email-voucher.html.twig', [
                    'order'     =>  $order,
                    'voucher'   =>  $voucher,
                    'customer'  =>  $customer
                ]
            ), 'text/html');

        $this->mailer->send($message);
    }
}

I always get the error Unable to find template \\"Emails/email-voucher.html.twig\\".

So, here's a summary of what I've tried:

• Basically everything suggested on similar StackOverflow questions
• Moving templates to app/Resources/views
• Every path/relative path I can think of in the call to ->render()
• Pulling my hair out

Any ideas?

Even if your service lies in the same namespace as it's your template, that does not mean that you can call it directly like that. Did you tried the way you render normal controller templates, like this:

->setBody($this->twig->render(
            'AppBundle:Emails:email-voucher.html.twig', [
                'order'     =>  $order,
                'voucher'   =>  $voucher,
                'customer'  =>  $customer
            ]
        ), 'text/html');
