I have an service class with the class name NewsService.
The service is configured as follows:
services:
portal.news:
class: xxx\NewsBundle\Service\NewsService
arguments: ["#doctrine.orm.entity_manager"]
I use Phpstorm with symfony plugin - The plugin finds the service, but Symfony itself does not.
I get the following error message:
An exception has been thrown during the rendering of a template ("You have requested a non-existent service "portal.news".").
How I use the service:
{{ render(controller('xxBundle:Widget:renderNews', {'slice_length': 250})) }}
in the Controller xxBundle:Widget:renderNews: $articles = $this->get('portal.news')->getNewestArticles($count);
cache is cleared
I checked everything (wrong service configuration, bundle is loaded, syntax is ok, ...)
You probably forgot to set public: true to your service, because since 3.4 all Symfony services are private by Default.
Also, you should avoid $this->get() functions and prefer fetching directly your service from your controller arguments
<?php
use xxx\NewsBundle\Service\NewsService
class MyController {
public function myAction(NewsService $service) {}
}
Using Service that needs an argument, you need to declare your service as an alias https://symfony.com/doc/current/service_container.html#explicitly-configuring-services-and-arguments

i wanna use ClientInterface in my class constructor and i give an error :
Cannot autowire service "App\Service\DelayReportService": argument "$client" of method "__construct()" references interface "Predis\ClientInterface" but no such service exists. Did you create a class that implements this interface?
seems to be i should add it manually to services.yml i added it like :
Predis\ClientInterface: '#Predis\Client'
and now i give this error:
You have requested a non-existent service "Predis\Client".
what is the solution and why symfony itself dont handle it?
you seem to be confused about how to define a service... which isn't surprising tbh
look here
https://symfony.com/doc/5.4/service_container.html#explicitly-configuring-services-and-arguments
for example
services:
App\Service\Concerns\IDevJobService:
class: App\Tests\Service\TestDevJobService
autowire: true
public: true
where
IDevJobService is an INTERFACE
and
TestDevJobService
is the actual implementation that will be auto injected
using # inside the yaml files is done to reference a service that has already been defined ELSEWHERE
https://symfony.com/doc/5.4/service_container.html#service-parameters
you probably want to watch symfonycasts services tutorial (I am not affiliated and I havent watched it myself yet (sure wish I did)).
EDIT
Predis\Client is a 3rd party class. It isn't in your App namespace or in your src folder. Symfony checks the src folder for class that it will then make to a service. See services.yaml there is a comment there, look for exclude and resource. And I'm not sure, even if you autoload it, that you can then just do #Predis\Client to reference an existing service.
be sure as well to debug your config using
php bin/console debug:autowiring
under linux you could do as well php bin/console debug:autowiring | grep Predis to find it more quickly (if it is there at all)
I have a controller, let's say Acme\ShopBundle\Controller\ProductListController
And its definition in services.yml is as follows:
services:
Acme\ShopBundle\Controller\ProductListController:
class: Acme\ShopBundle\Controller\ProductListController
arguments: ['#product_service']
Which throws this in my log file:
User Deprecated: The "Acme\ShopBundle\Controller\ProductListController" service is private, checking for its existence is deprecated since Symfony 3.2 and will fail in 4.0.
Followed by
User Deprecated: The "Acme\ShopBundle\Controller\ProductListController" service is private, getting it from the container is deprecated since Symfony 3.2 and will fail in 4.0. You should either make the service public, or stop using the container directly and use dependency injection instead.
The stack trace list of files is completely inside vendor/symfony so I'm assuming something is misconfigured, but stumped as to what. Any help appreciated.
Controller service must be public:
services:
Acme\ShopBundle\Controller\ProductListController:
public: true
arguments: ['#product_service']
Why aren't you using autowiring anyway? You could register all of your controllers then:
Acme\ShopBundle\Controller\:
resource: '../src/Acme/ShopBundle/Controller' # mutatis mutandis
tags: ['controller.service_arguments']

I am trying to inject #validator into my service but LiipFunctionalTestBundle is overriding that service when it gets injected.
admin.image_service:
class: AdminBundle\Service\ImageService
arguments: ["#validator", "#doctrine.orm.admin_entity_manager", "#image_storage_filesystem"]
Which results in the error
must be an instance of Symfony\Component\Validator\Validator\RecursiveValidator, instance of Liip\FunctionalTestBundle\Validator\DataCollectingValidator given
running php bin/console debug:container results in
liip_functional_test.validator: Liip\FunctionalTestBundle\Validator\DataCollectingValidator
validator: alias for "liip_functional_test.validator"
Is there a way to get around this over than remove liip and refactor all of my tests?
In Your service you should typehint Interface not exact class.
Instdead Symfony\Component\Validator\Validator\RecursiveValidator use Symfony\Component\Validator\Validator\ValidatorInterface - which is implemented by both classes (Symfony and Liip).
I have a bundle I am working on. In the extension for configurations, I am dependant on a service defined in a different bundle, but I get messages that the service is not defined. What can I do to call the services from the other bundle?
EDIT: Here is how I am trying to get the session service.
This is the bundle extension (simplified)
class BundleExtension
{
function load()
{
$this->container->get('bundle.service');
}
}
And here is the services.yml that I am using (again, simplified)
services:
bundle.service:
class: ServiceClass
arguments: [ #session ]
The error I am getting is:
InvalidArgumentException: The service definition "session" does not exist.
I am trying to write my own messages to the log in Symfony 2.3, from anywhere, and not just the Controller (which I realize you can just do a "$this->get('logger')".
I've seen that in Symfony 1 you can use sfContext, but that class no longer seems to be a viable choice in 2.3.
Any help is appreciated.
Symfony2 has Service-oriented architecture (http://en.wikipedia.org/wiki/Service-oriented_architecture) and logger is one of service (by default Monolog). In controller you have access to service via $this->get('service_name'). Here is more info about service container: http://symfony.com/doc/current/book/service_container.html#what-is-a-service-container. If you wanna use logger in another service you have to define service and inject logger service. Example:
# section with defined service in your config.yml file (by default in config.yml)
services:
# your service name
my_service:
# your class name
class: Fully\Qualified\Loader\Class\Name
# arguments passed to service constructor. In this case #logger
arguments: ["#logger"]
# tags, info: http://symfony.com/doc/current/components/dependency_injection/tags.html
tags:
- { name: monolog.logger, channel: acme }
Additionally you should familiarize with dependency injection docs: http://symfony.com/doc/current/components/dependency_injection/index.html
I hope that helped. If not, please let me know where exactly you want to use logger.
