I have a Service that get's the current logged in user, which only works some of the time whilst in the dev environment.
The problem seems to be whenever I change the Twig templates and refresh I get the error:
Error: Call to a member function getUser() on null If I refresh the page everything works as it should until I update the Twig template again. This obviously makes development very slow as I'm constantly refreshing the page.
Things I have done so far:-
- Cleared the dev environment cache.
- Cleared the browser cache.
- Confirmed the user is definitely logged in (otherwise it wouldn't work the on the second refresh)
Does anyone have any ideas what could be causing the problem?
services.yml
myservice: class: AppBundle\Services\MyService arguments: ["@doctrine.orm.entity_manager", "@security.token_storage"] MyService.php
<?php namespace AppBundle\Services; use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface; class MyService { private $em; private $token; public function __construct($entityManager, TokenStorageInterface $tokenStorage) { $this->em = $entityManager; $this->token = $tokenStorage->getToken(); } public function doSomething() { $user_id = $this->token->getUser()->getID(); return; } } Twig Template
{{ myservice.doSomething }} Note: This is the bare-bones code that still causes the problem

I'm not certain, but it looks to me like your class should maintain a pointer to the tokenStorage class, not the token itself (as this may change). Your service would then look like this:
class MyService { private $em; private $tokenStorage; public function __construct($entityManager, TokenStorageInterface $tokenStorage) { $this->em = $entityManager; $this->tokenStorage = $tokenStorage; } public function doSomething() { $user_id = $this->tokenStorage->getToken()->getUser()->getID(); return; } }
