Send email from command line in symfony2

Question

I need to render a twig template from a command class in symfony2.

namespace IT\bBundle\Command;  use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand; use Symfony\Component\Console\Input\InputArgument; use Symfony\Component\Console\Input\InputInterface; use Symfony\Component\Console\Input\InputOption; use Symfony\Component\Console\Output\OutputInterface;  class CronCommand extends ContainerAwareCommand {     protected function configure()     {         $this             ->setName('send:emails')             ->setDescription('Envio programado de emails');     }      protected function execute(InputInterface $input, OutputInterface $output)     {         $message = \Swift_Message::newInstance()             ->setSubject('bla bla')             ->setFrom('[email protected]')             ->setTo('[email protected]')             ->setCharset('UTF-8')             ->setContentType('text/html')                    ->setBody($this->renderView('mainBundle:Email:default.html.twig'));          $this->getContainer()->get('mailer')->send($message);         $output->writeln('Enviado!');     } } 

But when I execute the command php app/console send:emails I get the following error:

Fatal error: Call to undefined method IT\bBundle\Command\CronCommand::renderView()

How can I render the view?

Answer 1

It's because renderView is method of class Controller. Instead of that try:

$this->getContainer()->get('templating')->render(...);
