I am working on the last part of my reset password system. All I need is for Symfony to send the URL that contain the token by email. When I execute the controller I get the following message:

Call to a member function get() on null (500 Internal Server Error)

If I remouve the "extends Controller" i get this error

What I don't get is that I copied the code from an other controller in the same project that sends email with out any problems.

My controller

}

It uses renderView which I never got working but render did the trick and now the get-> part that does not seem to work. I extended the controller the same way and did not find anything in the service file that would suggest I need to do something else.

You're trying to call the method get() of ContainerInterface.
To be able to use this method, add ContainerInterface as a part of your service dependencies. So, you can use this attributes to call the get() function

for example:

$this->container->get('app.mailer')

Ok so I played arround and readed a lot and never understood why get-> is not working in my controller ... but I managed to go arround it like so.

class ForgotPasswordEventListener
{

private $templating;

private $manager;

protected $mailer;



public function __construct($templating, DoctrineORMEntityManager $manager, Swift_Mailer $mailer)

{

    $this->templating = $templating;

    $this->manager=$manager;

    $this->mailer=$mailer;

}



/**

 * @param ForgotPasswordEvent $event

 */

public function onCreateToken(ForgotPasswordEvent $event)

{

        $message = (new Swift_Message('Intranet Québec en réseau : Mot de passe oublier'))

            ->setFrom('noreply@quebecenreseau.ca')

            ->setTo($user->getEmail())

            ->setBody(

                $this->templating->render(

                    // templates/emails/registration.html.twig

                    '_Emails/change-password.html.twig',

                    array(

                        'name' => $user->getName(),

                        'tokenLink' => "https://www.quebecenreseau.ca/intranet/password-change/".$user->getId()."/".$passwordToken->getToken()

                    )

                ),

                'text/html'

            );

        if (0 === $this->mailer->send($message)){

            throw new RuntimeException('Unable to send email');

        }else{

            echo "done";

        }   

[...]

As for my service i did this:

app.listener.forgot_password:

    class: AppBundleEventForgotPasswordEventListener      

    arguments:

        - "@templating"

        - "@doctrine.orm.entity_manager"

        - "@mailer"

    tags:

        - { name: kernel.event_listener, event: coop_tilleuls_forgot_password.create_token, method: onCreateToken}

        - { name: templating.helper, alias: templating, event: coop_tilleuls_forgot_password.create_token, method: onCreateToken}

        - { name: kernel.event_listener, event: coop_tilleuls_forgot_password.update_password, method: onUpdatePassword }

I wish i could of understood why but this will do for now. Hope this helps sombody else in the future!
