Symfony 3.0.9 can't access getUser() from my service - symfony

I am trying to access my user from a service in symfony 3.0.9 with the following:
in my service.yaml:
seal_service:
class: FrontBundle\Service\SealService
public: true
arguments:
- "#service_container"
and my service is like this:
class SealService
{
protected $container = null;
public function __construct(ContainerInterface $container)
{
$this->container = $container;
}
public function getAvailableSeals($sn = null){
$user = $this->container->get('fos_user.user_manager')->getUser();
...
}
but I am getting the following error:
Attempted to call an undefined method named "getUser"
I also tried $this->container->get('fos_user.user_manager')
if I use $this->container->get('fos_user.security.controller') I get Call to protected method Symfony\Bundle\FrameworkBundle\Controller\Controller::getUser() from context 'FrontBundle\Service\SealService'
What am I doing wrong please ?

Don't inject container in service:
inject token storage instead.
seal_service:
class: FrontBundle\Service\SealService
public: true
arguments:
- ["#security.token_storage","#doctrine.orm.entity_manager"]

here is the answer:
$tokenStorage = $this->container->get('security.token_storage')->getToken();
$user = $tokenStorage->getUser();

Use the following:
$this->container->get('security.token_storage')->getToken()->getUser();
Anyway, avoid injecting the whole container, if you only need security context.

Symfony 4 Accessing Swift_Mailer in Service

I have been looking at the Symfony 4.1 documentation on using the Swift_mailer. However, it appears the documentation is only assumed it being used in the Controller classes. I'm trying to create a Service with some reusable functions that send email.
I created a EmailService.php file in my service directory. When creating a new instance of this service, it quickly throws and error:
"Too few arguments to function
App\Service\EmailService::__construct(), 0 passed in
*MyApp\src\Controller\TestController.php on line 33
and exactly 1 expected"
I'm not sure how to pass \Swift_Mailer $mailer into the __construct correctly? I have auto wiring enabled in the services.yaml, so i'm not sure what I need to do differently?
class EmailService
{
private $from = 'support#******.com';
private $mailer;
public function __construct(\Swift_Mailer $mailer)
{
$this->mailer = $mailer;
}
How do I pass the \Swift_Mailer into this EmailService construct?
I tried adding this to my config\services.yaml with no success:
App\Service\EmailService:
arguments: ['#mailer']
As mentioned by dbrumann in a comment, I needed to follow the proper way of injecting services.
First, I needed to add the services to config/services.yaml
#config/services.yaml
emailservice:
class: App\Service\EmailService
arguments: ['#swiftmailer.mailer.default', '#twig']
public: true
Second, I need to setup the service to accept both the mailer, and twig for rendering the template.
#App/Service/EmailService.php
<?php
namespace App\Service;
class EmailService
{
private $from = 'support#*****.com';
private $mailer;
private $templating;
public function __construct(\Swift_Mailer $mailer, \Twig\Environment $templating)
{
$this->mailer = $mailer;
$this->templating = $templating;
}
public function userConfirmation(string $recipient, string $confCode) : bool
{
$message = (new \Swift_Message())
->setSubject('Some sort of string')
->setFrom($this->from)
->setTo($recipient)
->setBody(
$this->templating->render(
'email/UserConfirmation.html.twig',
array('confCode' => $confCode)
),
'text/html'
)
/*
* If you also want to include a plaintext version of the message
->addPart(
$this->renderView(
'emails/UserConfirmation.txt.twig',
array('confCode' => $confCode)
),
'text/plain'
)
*/
;
return $this->mailer->send($message);
}
}
Third, to call it from the controller, make sure your controller is extending Controller and not the AbstractController! Crucial step!! Here is an example based on the parameters I require in my service:
public function userConfirmation()
{
$emailService = $this->get('emailservice');
$sent = $emailService->userConfirmation('some#emailaddress.com', '2ndParam');
return new Response('Success') //Or whatever you want to return
}
I hope this helps people. AbstractController does not give you the proper access to the service containers.
#config/services.yaml
App\Service\EmailService
arguments: ['#swiftmailer.mailer.default']
public: true
And in your controller :
public function userConfirmation(EmailService $emailService)
{
$sent = $emailService->userConfirmation('some#emailaddress.com', '2ndParam');
return new Response('Success') //Or whatever you want to return
}
Use FQCN "App\Service\MyService" to declare services in services.yaml and a proper legacy_aliases.yaml file to declare legacy aliases like "app.service.my.service" it helps keep your services.yaml clean...

#mailer and #twig in argument of a service error ServiceCircularReferenceException

I'm trying to put twig like argument of my service but i have always the same error :
ServiceCircularReferenceException in bootstrap.php.cache line 2129
Circular reference detected for service "doctrine.orm.default_entity_manager",path: "doctrine.orm.default_entity_manager -> doctrine.dbal.default_connection -> wh.participant_listener -> wh.participant_notification -> twig -> security.authorization_checker -> security.authentication.manager -> fos_user.user_provider.username -> fos_user.user_manager".`
This is my service.yml file
wh.participant_notification:
class: WH\TrainingBundle\Notification\Notification
arguments: [#mailer, #twig]
wh.participant_listener:
class: WH\TrainingBundle\EventListener\ParticipantListener
arguments: [#wh.participant_notification]
tags:
- { name: doctrine.event_listener, event: postUpdate }
- { name: doctrine.event_listener, event: postPersist }
My PartcicipantListenerFile
namespace WH\TrainingBundle\EventListener;
use Doctrine\ORM\Event\LifecycleEventArgs;
use WH\TrainingBundle\Notification\Notification;
class ParticipantListener
{
protected $notification;
public function __construct(Notification $notification)
{
$this->notification = $notification;
}
}
This probleme exist only when i pass #wh.participant_notificationin arguments of my second service
Any body has an idea ?
Thank's a lot
I've find a solution, not pretty, but it works :
First i pass the service container in argument of my service
services:
wh.participant_notification:
class: WH\TrainingBundle\Notification\Notification
arguments: ['#service_container']
wh.participant_listener:
class: WH\TrainingBundle\EventListener\ParticipantListener
arguments: ['#wh.participant_notification']
tags:
- { name: doctrine.event_listener, event: postPersist }
then in my Notification.php class :
use Symfony\Component\DependencyInjection\ContainerInterface as Container;
private $container;
public function __construct(Container $container) {
$this->container = $container;
}
public function subscribValidation ($participant) {
$templating = $this->container->get('templating');
$mailer = $this->container->get('mailer');
...
I can't create protected var $twig because the probleme persiste.
I repeat, its only with twig service (or template).
Maybe another one find a better solution ...
The circular message, while unclear, should guide you.
Doctrine entity manager loads its listeners,wh.participant_notification among them. Your service requires twig which in turns requires a chain of other things, doctrine entity manager among them. This causes the exception above.
One solution to this issue could be to use setter injection
So you can just define your service as:
wh.participant_notification:
class: WH\TrainingBundle\Notification\Notification
calls:
- [setMailer, ["#mailer"]]
- [setTemplating, ["#templating"]]
and add to your Notification class the setter methods
class Notification
{
private $mailer;
private $templating;
public function setMailer(\Mailer $mailer)
{
$this->mailer = $mailer;
}
public function setTemplating(\Symfony\Bundle\TwigBundle\TwigEngine $templating)
{
$this->templating= $templating;
}
...your code...

Inject Container in Entity Repository

I want to get Current locale in my Repository.That's why I am injecting the Container into my Repository but I am getting error that I am unable to figure it out.
This is my service.yml code
survey.repository.container_aware:
class: Demo\SurveyBundle\Repository\SurveyRepository
calls:
- [ setContainer, [ #service_container ] ]
and this is my repository class code
.......
use Symfony\Component\DependencyInjection\ContainerInterface as Container;
.......
protected $container;
public function __construct(Container $container) {
$this->container = $container;
}
After that I am getting below error
ContextErrorException: Catchable Fatal Error: Argument 1 passed to
Demo\SurveyBundle\Entity\SurveyRepository::__construct() must implement
interface Symfony\Component\DependencyInjection\ContainerInterface, instance of
Doctrine\ORM\EntityManager given
What I am missing in my construct or in service?
You are passing the container with the Setter Injection (in the yml) but you define it in the constructor class.
BTW the entity manager already have a constructor class with arguments so don't take the Constructor Injection and simply change your method in the class as:
public function setContainer(Container $container) {
$this->container = $container;
}
You actually have another major issue here. From the error message it's obvious that you are trying to access your doctrine repository using the entity manager. Something like:
$repo = $em->getRepository('whatever');
The service container code is never being used and it really does not matter what you do, you still won't get your container injected. Creating a repository as a service requires using the entity manager as a factory and takes some additional lines in your services.yml file.
Something like:
# services.yml
cerad_person.person_repository.doctrine:
class: Cerad\Bundle\PersonBundle\Entity\PersonRepository
factory_service: 'doctrine.orm.default_entity_manager'
factory_method: 'getRepository'
arguments:
- 'Cerad\Bundle\PersonBundle\Entity\Person'
calls:
- [ setContainer, [#container] ]
// controller
$personRepo = $this->get('cerad_person.person_repository.doctrine');
That will give you a repository with the container injected.
#devilciuos - %locale% will only give you the default locale and not whatever is passed as _locale in the request. Unfortunately it seems to take a listener to access the request local via a service: https://github.com/symfony/symfony/issues/5486
You're not passing the container to the constructor, but to setContainer. So you shouuld declare a public method setContainer in SurveyRepository:
Demo/SurveyBundle/Entity/SurveyRepository.php
protected $container;
public function setContainer(Container $container) {
$this->container = $container;
}
or pass the container to the constructor:
DemoSurveyBundle/Resources/Config/services.yml
survey.repository.container_aware:
class: Demo\SurveyBundle\Repository\SurveyRepository
arguments: [#service_container]
Edit:
By the way, if you only need the locale, wouldn't be enough to pass the %locale% parameter instead of the whole container?
survey.repository.container_aware:
class: Demo\SurveyBundle\Repository\SurveyRepository
calls:
- [ setLocale, [ %locale%] ]
protected $locale;
public function setLocale($locale) {
$this->locale = $locale;
}

Symfony2 access user and doctrine in a service

I'm running the equivalent of this code in lots and lots of controller actions, basically it grabs the user's username, and if that username is attached to a blog entity it will allow the user to see the blog entity(s):
$em = $this->getDoctrine()->getManager();
$user = $this->get('security.context')->getToken()->getUser();
$entities = $em->getRepository('MySiteBundle:Blog')->findBy(array('user' => $user));
return $this->render('MySiteBundle:Blog:index.html.twig', array(
'entities' => $entities,
I want to move it into a service so I can cut down on code repetition. I want to avoid doing as much logic in my controllers as possible.
That being said, I'm not sure how I can access the user session and doctrine in a service.
Here's my services.yml:
mysite.user.blog:
class: MySite\SiteBundle\Services\BlogUser
And here's how I was attempting to call it in the controller:
public function testAction() {
$response = $this->get('mysite.user.blog');
return new Response($response);
}
I did try using an event subscriber/listener tag, but that doesn't seem to accomplish the task I want.
Here is my completely horrible attempt at a service. I couldn't get any response from it without using a constructor.
namespace MySite\SiteBundle\Services;
use MySite\SiteBundle\Entity\Blog;
class BlogUser {
protected $entities;
public function __construct(){
$em = $this->getDoctrine()->getManager();
$user = $this->get('security.context')->getToken()->getUser();
$this->entities = $em->getRepository('MySiteBundle:Blog')->findBy(array('user' => $user));
}
}
Am I going about this the completely wrong way? Is there a better way that I'm missing?
EDIT/ANSWER:
modified my naming convention a little:
//services.yml
mysite.user.blog.entities:
class: Mysite\SiteBundle\Services\BlogUser
arguments: ["#doctrine.orm.entity_manager", "#security.context"]
In the controller action:
$userEntities = $this->get('mysite.user.blog.entities');
$entities = $userEntities->getEntities();
In the service itself:
class BlogUser {
protected $entities;
public function __construct($em, $securityContext){
$user = $securityContext->getToken()->getUser();
$this->entities = $em->getRepository('MySiteBundle:Blog')->findBy(array('user' => $user));
}
public function getEntities(){
return $this->entities;
}
}
Still needs two lines to get the $entities variable in the controller, but this is way better than defining the same thing over and over.
"Security.context" has been deprecated since Symfony 2.6
After some community discussions, it was decided that SecurityContext gives too many dependencies to retrieve a simple Token/User object. That's why, starting with Symfony 2.6, thesecurity.context service has been deprecated and split into two new services:security.authorization_checker and security.token_storage.
Source
Thus, the new way to do it would be, first configure your service as:
mysite.user.blog:
class: MySite\SiteBundle\Services\BlogUser
arguments: ["#doctrine.orm.entity_manager", "#security.token_storage"]
Then in the service class constructor:
class BlogUser
{
protected $user;
protected $entities;
public function __construct(EntityManager $em, TokenStorage $tokenStorage)
{
$this->user = $tokenStorage->getToken()->getUser();
$this->entities = $em->getRepository('MySiteBundle:Blog')->findBy(array('user' => $user));
}
}
Yes, you are doing it in wrong way. Let's look at your code:
# call to undefined object method getDoctrine()
$em = $this->getDoctrine()->getManager();
# call to undefined object method get()
$user = $this->get('security.context')->getToken()->getUser();
You cannot call getting entitymanager and security.context in your service in the same way like in your controller. Instead, you have to inject entitymanager and security.context services. Example:
# services.yml
mysite.user.blog:
class: MySite\SiteBundle\Services\BlogUser
calls:
- [ setUserFromSecurityContext, [ #security.context ]]
- [ setEntityManager, [ #doctrine.orm.entity_manager ]]
And improved service:
namespace Catablog\SiteBundle\Services;
use MySite\SiteBundle\Entity\Blog;
class BlogUser {
private $entityManager;
private $user;
public function setEntityManager(EntityManager $entityManager)
{
$this->entityManager = $entityManager;
}
public function setUserFromSecurityContext(SecurityContext $securityContext)
{
# notice, there are a cases when `getToken()` returns null, so improve this
$this->user = $securityContext->getToken()->getUser();
}
public function getEntities(){
# your code here
}
}
More info about Dependency injection
You are looking on how to 'inject' other services into your custom service. Take a look at Service Container documentation.
In your case, you can inject doctrine.orm.entity_manager and security.context services into your BlogUser class via constructor injection. For example:
class BlogUser {
public function __construct($em, $securityContext) {
$user = $securityContext->getToken()->getUser();
$this->entities = $em->getRepository('MySiteBundle:Blog')->findBy(array('user' => $user));
}
}
And configure your service as the following:
mysite.user.blog:
class: MySite\SiteBundle\Services\BlogUser
arguments: ["#doctrine.orm.entity_manager", "#security.context"]

Set parameter for Doctrine filter on every request in Symfony2

I have a Doctrine filter in Symfony2 project. I am trying to set filter's parameter to some value (taken from session) on every request.
The problem is that filter object is created after Symfony's onKernelRequest event, so I can't set it from there. If I try to set it in Doctrine's postConnect event circular dependency is detected:
ServiceCircularReferenceException: Circular reference detected for service "doctrine.orm.private_entity_manager", path: "routing.loader -> assetic.asset_manager -> twig -> translator.default -> doctrine.orm.private_entity_manager -> doctrine.dbal.private_connection -> year_visibility.parameter_setter".
The question is, where (or rather how) should I set filter's parameter?
You can try to define filters manually and pass required parameters at the same time.
services:
app.filter_manager:
class: App\Bundle\AppBundle\Filter\FilterManager
arguments: [#doctrine.orm.entity_manager, #session]
tags:
- { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
And in the filter manager class:
// ...
public function __construct(EntityManager $em, SessionInterface $session)
{
$this->em = $em;
$this->session = $session;
}
// ...
public function onKernelRequest()
{
$this->em->getConfiguration()->addFilter('filter_name', 'Filter/Class/Name/With/Ns');
$filter = $this->em->getFilters()->enable('filter_name');
$filter->setParameter('param_name', $this->session->get('param_name'));
}
As seen here: https://stackoverflow.com/a/14650403/244058 ,
you can have an instance of your Filter class at kernel boot.
So, your instance would be available very early.
<?php
class MyBundle extends Bundle
{
public function boot()
{
$em = $this->container->get('doctrine.orm.default_entity_manager');
$conf = $em->getConfiguration();
$conf->addFilter(
'filter_name',
'Doctrine\Filter\TestFilter'
);
// either enable it here, or later in the event listener
$em->getFilters()->enable('filter_name');
}
}
After that, just add a kernel.event_listener that listens on kernel.request and set a filter parameter (something like this):
<?php
class DoctrineSqlFilterConfigurator
{
private $em; // inject the entity manager somehow (ctor is a good idea)
public function onKernelRequest(GetResponseEvent $event)
{
$filter = $this->em->getFilters()->enable('filter_name');
$filter->setParameter('param_name', $event->getRequest()->getSession()->get('param_name'));
}
}
