I am trying to implement a custom repository class in symfony2, and I want it to extend EntityRepository class. I am having trouble with passing the getting arguments to the parent (i.e. EntityRepository) constructor. This is the signiture of parent constructor:
public function __construct($em, Mapping\ClassMetadata $class)
So I had to add this to my services.yml file, in order to get the arguments:
parameters:
user_provider.class: Untitled\F5Bundle\Security\UserRepository
services:
user_meta_data:
class: Doctrine\ORM\Mapping\ClassMetaData
arguments:
name: "Untitled\F5Bundle\Entity\User"
user_provider:
class: "%user_provider.class%"
arguments:
entityManager: "#doctrine.orm.entity_manager"
meta_data: "#user_meta_data"
And I also added the annotation tag to my User class (which I'm not sure if it was neccessary)
Now when I run it, it raises an error. the message says:
FatalErrorException: Error: Class 'Doctrine\ORM\Mapping\ClassMetaData' not found
in /mnt/data/Projects/F5/app/cache/dev/appDevDebugProjectContainer.php line 2749
(/mnt/data/Projects/F5/ is where I keep the code)
I don't get it. What's wrong here? What am I doing wrong?
Metadata is obtained with the MetadataFactory. As an example you can see how it works in EntityManager.
public function getClassMetadata($className)
{
return $this->metadataFactory->getMetadataFor($className);
}
You can retrieve you repository as service as well. Look at this question.
You don't need to inject these constructor arguments yourself, just specify which repository class you want to use:
/**
* #Entity(repositoryClass="MyProject\UserRepository")
*/
class User
{
...
}
See also http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/annotations-reference.html#entity
You miss typed classname "ClassMetaData" should be ClassMetadata
class: Doctrine\ORM\Mapping\ClassMetadata

I can't read a parameter from parameters.yml in my controller.
I want to do this:
//My Controller
class ExampleController extends Controller
{
function someMethod($argument)
{
dump($this->getParameter('free_proxy'));die();
and in parameters.yml I got:
parameters:
free_proxy: "http://xxx:8080"
I get an error: Call to a member function getParameter() on null
I've tested some solutions like adding some services and using get and stuff but nothing works.
EDIT: also, I tried this:
services:
_defaults:
autowire: true
autoconfigure: true
public: false
bind:
$freeProxy: '%free_proxy%'
Then using:
$this->container->getParameter('free_proxy');
But I got an error: Unused binding "$freeProxy" in service...
So there are two mysteries here. First is why is the container not being injected which in turn causes getParameter to fail. And second, why does bind generate that unused binding error.
You did not show your routing but I suspect that somewhere along the line you actually have:
$exampleController = new ExampleController();
If so then this explains why getParameter is failing. You really need to let Symfony create the controller based on the route. Otherwise the container is not injected and other controller magic is skipped.
I installed a fresh 3.4 app with the old directory structure and added a parameter
composer create-project symfony/framework-standard-edition s34
# app/config/parameters.yml
parameters:
free_proxy: "http://xxx:8080"
I then tweaked the default controller using the default route annotation:
class DefaultController extends Controller
{
/**
* #Route("/", name="homepage")
*/
public function indexAction(Request $request)
{
$freeProxy = $this->getParameter('free_proxy');
// replace this example code with whatever you need
return $this->render('default/index.html.twig', [
'base_dir' => realpath($this->getParameter('kernel.project_dir')).DIRECTORY_SEPARATOR.$freeProxy,
]);
}
}
And everything worked as expected. The Symfony request handler takes care of injecting the container and thus gives you access to the parameters. If you cannot get this working then please update your question with your routing information.
I then took a look at the bind issue. You really want to inject these parameters instead of pulling them. I updated services.yml
# app/config/services.yml
services:
bind:
$freeProxy: '%free_proxy%'
And started getting those unused binding errors. It turns out that bind does not work for action injection. Not really sure why. I don't use it much but I really would have expected that just adding $freeProxy to your action method would work. In any event, here is a working example of the proper way to do things.
class ExampleController extends Controller
{
private $freeProxy;
public function __construct($freeProxy)
{
$this->freeProxy = $freeProxy;
}
/**
* #Route("/example", name="example")
*/
function someMethod()
{
dump($this->freeProxy);
dump($this->getParameter('free_proxy'));die();
}
}
I then went to a fresh 4.2 project and tried action injection:
class IndexController extends AbstractController
{
public function index($freeProxy)
{
return new Response("Index $freeProxy");
}
}
Action injection works as expected for 4.2 but not 3.4. Constructor injection works fine in either version.
documentation show like this :
parameters.yml :
parameters:
mailer.transport: sendmail
to set :
$container->setParameter('mailer.transport', 'sendmail');
to get :
$container->getParameter('mailer.transport');
How can I inject one service inside another in Symfony 3.4?
Assuming I have this structure:
AppBundle
Service
ServiceOne.php
ServiceTwo.php
My services.yml looks like:
services:
...
AppBundle\Service\serviceOne:
arguments: [...]
service_one:
alias: AppBundle\Service\serviceOne
AppBundle\Service\ServiceTwo:
arguments: ["#logger", "#service_one"]
This gives me an error:
[2018-07-31 10:37:43] request.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\ClassNotFoundException: "Attempted to load class "ServiceOne" from namespace "AppBundle\Service". Did you forget a "use" statement for another namespace?" at /symfony/var/cache/dev/ContainerKoj7t1p/getServiceOneService.php line 12 {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\ClassNotFoundException(code: 0): Attempted to load class \"ServiceOne\" from namespace \"AppBundle\\Service\".\nDid you forget a \"use\" statement for another namespace? at /symfony/var/cache/dev/ContainerKoj7t1p/getServiceOneService.php:12)"} []
ServiceTwo.php:
<?php
namespace AppBundle\Service;
use Psr\Log\LoggerInterface;
class ServiceTwo {
private $logger;
private $serviceOne;
public function __construct(LoggerInterface $logger, ServiceOne $serviceOne) {
$this->logger = $logger;
$this->serviceOne = $serviceOne;
}
...
I already tried this solution It seems it is for an older version of symfony.
And I cleared cache as well.
check Typos. The file ServiceOne.php should contain one class ServiceOne and should be named in service.yml as ServiceOne (with namespace)
you should not define a service twice, AppBundle\Service\ServiceOne: ~ will fit
you should active autowiring. this means you don't need to configure thoses services. Only if you need public usage. But than you still dont need to confige the arguments
Look here Autowiring : https://symfony.com/doc/current/service_container/autowiring.html
and here autoloading: https://symfony.com/doc/3.4/service_container.html#injecting-services-config-into-a-service
I have the class, it declare as service. When I get() my service I run some method and this method require two params what I want to let user configure in config.yml. How I can get these parameters in this class? Maybe exist some way to do this in my service definition? Or I need extend my class from ContainerAware (if I am right its bad practice)? Thanks!
You can inject parameters into your service using %param_name% syntax
services.yml
services:
your_service:
class: Acme\DemoBundle\YourClass
arguments: [#some.other.service, %my_parameter%]
parameters.yml
parameters:
my_parameter: my_value
You can use call them using the constructor
acme.your_service:
class: Acme\DemoBundle\YourService
arguments: [%param1%]
in the class
class YourService {
protected $param1;
public function __construct($param1) {
$this->param1 = $param1;
}
}
I have service PgHistService in subdirectory Service in DbExtensionBundle:
namespace Iba\DbExtensionBundle\Service;
class PgHistService { ...}
This service is defined in bundles's services.yml and can be sucessfully included in a controller via $this->get('pghist.service'):
parameters:
pghist.service.class: Iba\DbExtensionBundle\Service\PgHistService
services:
pghist.service:
class: %pghist.service.class%
arguments:
entityManager: "#doctrine.orm.entity_manager"
Now I want to inject it with JMS\DIExtraBundle in doctrine entity listener:
namespace Iba\DbExtensionBundle\Entity;
use JMS\DiExtraBundle\Annotation as DI;
class BaseEntityListener {
/** #DI\Inject("pghist.service") */
public $pgHist;
}
Variable pgHist is always null. What am I doing wrong, please? I tried to set this in config.yml but it doesn't work either:
jms_di_extra:
locations:
all_bundles: false
bundles: [DbExtensionBundle]
directories: ["%kernel.root_dir%/../vendor/iba/db-extension-bundle/Iba/DbExtensionBundle/Service"]
Jason Roman is right, thank you.
If you want to use JMS\DiExtraBunde together with entity listener, you have to use DIExtraBundle own system of invoking listener via annotation #DoctrineListener in listener instead of Doctrine standard one #EntityListeners in the entity.
Ok, I wan't to to something extremely simple, I just want to get this value from app/config/config.yml
framework:
default_locale: nl
I want to get this value in an EventListener.. Can anyone help?
Edit 1: (is this right)? but i dont use the DependencyInjection classes here.. im confused..
services:
core_locale.locale_listener:
class: Eyee\CoreBundle\EventListener\LocaleListenerDefault
arguments: ["%kernel.default_locale%"]
<?php
namespace Eyee\CoreBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
/**
* use this class if no database Languages available..
*/
class LocaleListenerDefault implements EventSubscriberInterface
{
private $defaultLocale;
public function __construct($default_locale = 'en')
{
$this->defaultLocale = $default_locale;
}`enter code here`
I doesn't get what is your problem. To use an eventlistener you need to register the service in a service file. There you can pass argument to the constructor as you wrote above:
services:
core_locale.locale_listener:
class: Eyee\CoreBundle\EventListener\LocaleListenerDefault
arguments: ["%kernel.default_locale%"]
This should work.
Or what is your problem, what's not working there?
it depends wether you have access to the container in your class.
In a controller you can do:
$locale = $this->container->getParameter('framework.default_locale');
There are numerous answers on stackoverflow that already answer this question.
For a non-controller class you need to use dependency injection.
Please read the documentation chapters Introduction to Parameters.
