Symfony2电子邮件主题翻译。 命令和控制器之间的区别

Question

我今天遇到了翻译symfony的问题。

由SwiftMailer发送，电子邮件是在个人服务中创建的。

案例1：在Controller中调用函数sendWelcomeEmailMessage，只是在注册新用户时，trans键'registration.email.welcome.subject'被很好地翻译

情况2：在symfony2命令中调用函数sendReflationEmailMessage，但是在这里，键'registration.email.welcome.subject'（测试的相同键）未被翻译...

有人有想法吗？

/**
 * @param UserInterface $user
 */
public function sendWelcomeEmailMessage(UserInterface $user)
{
    $params = $this->parameters['registration']['welcome'];
    $rendered = $this->templating->render(
        $params['template'], [
            'user' => $user
        ]
    );

    $subject = $this->translator->trans('registration.email.welcome.subject');

    $this->sendEmailMessage($rendered, $subject, $params['from_email'], $user->getEmail());
}

/**
 * @param UserInterface $user
 */
public function sendReflationEmailMessage(UserInterface $user)
{
    $params = $this->parameters['registration']['reflation'];
    $rendered = $this->templating->render(
        $params['template'], [
            'user' => $user
        ]
    );

    $subject = $this->translator->trans('registration.email.welcome.subject'); // Same trans key, only for test

    $this->sendEmailMessage($rendered, $subject, $params['from_email'], $user->getEmail());
}

Answer 1

您的命令不处理config.yml ，然后它没有关于您当前语言环境的信息。 您需要明确设置它：

/**
 * @param UserInterface $user
 */
public function sendReflationEmailMessage(UserInterface $user)
{
    $params = $this->parameters['registration']['reflation'];
    $rendered = $this->templating->render(
        $params['template'], [
            'user' => $user
        ]
    );

    $this->translator->setLocale("en_EN");
    $subject = $this->translator->trans('registration.email.welcome.subject'); // Same trans key, only for test

    $this->sendEmailMessage($rendered, $subject, $params['from_email'], $user->getEmail());
}

Answer 2

您还可以使用ContainerAwareness ：

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;

class MyCommand extends ContainerAwareCommand
{
    public function sendReflationEmailMessage(UserInterface $user)
    {
        $params = $this->parameters['registration']['reflation'];
        $rendered = $this->templating->render(
            $params['template'], [
                'user' => $user
            ]
        );

        $subject = $this->getContainer()->get('translator')->trans('registration.email.welcome.subject');

        $this->sendEmailMessage($rendered, $subject, $params['from_email'], $user->getEmail());
    }
}

这应该处理你的config.yml 。

但最好的做法是不要注入完整的容器，而是注入翻译器，例如通过树枝。 然后你可以这样做：

$this->twig->getExtension('translator')->trans('registration.email.welcome.subject', array(), 'translation_domain');
