Getting the current locale in the service became a very hard task

[vladcosorg]

I need to get current locale, before i've injected session, and got locale from there, now, after upgrade, I have to get it from request, so I do:

services:
    entity_locale_setter.listener:
        class: Giftshop\FrontBundle\Listener\EntityLocaleSetter
        arguments: [@request]
        tags:
            - { name: doctrine.event_listener, event: postLoad }

Obviously i get the scope widening error

ScopeWideningInjectionException: Scope Widening Injection detected: The definition "entity_locale_setter.listener" references the service "request" which belongs to a narrower scope. Generally, it is safer to either move "entity_locale_setter.listener" to scope "request" or alternatively rely on the provider pattern by injecting the container itself, and requesting the service "request" each time it is needed. In rare, special cases however that might not be necessary, then you can set the reference to strict=false to get rid of this error.

Ok, i chnage it to scope:request and i get

ScopeWideningInjectionException: Scope Widening Injection detected: The definition "doctrine.dbal.default_connection.event_manager" references the service "entity_locale_setter.listener" which belongs to a narrower scope. Generally, it is safer to either move "doctrine.dbal.default_connection.event_manager" to scope "request" or alternatively rely on the provider pattern by injecting the container itself, and requesting the service "entity_locale_setter.listener" each time it is needed. In rare, special cases however that might not be necessary, then you can set the reference to strict=false to get rid of this error.

Can someone tell me please, how to get the freaking locale? :D Why is it so hard, or I;m doing something wrong?

I'm injecting now the service container, but I don't like this dirty approach.

Hmmm, did you tried to turn off this strict param ?

services:
    entity_locale_setter.listener:
        class: Giftshop\FrontBundle\Listener\EntityLocaleSetter
        arguments: [@request=]
        tags:
            - { name: doctrine.event_listener, event: postLoad }

If you only need the locale I suggest passing the %locale% parameter instead of the Request service.

@antoinegomez this will not give you the current locale but the default locale

@stloyd

Yes i did, no effect.

I think you come into the dark side of the dependency injection. Relaying on the request means moving to a narrower scope, because the request is created while the application is running.

But as jedi ninjas, let's try to solve this.

I would try to use a second event listener listening to kernel.request. This event gets your entity_locale_setter.listener service and sets the request manually when the kernel.request event occurs.

# services.yml

services:
    entity_locale_setter.listener:
        class: Giftshop\FrontBundle\Listener\EntityLocaleSetter
        tags:
            - { name: doctrine.event_listener, event: postLoad }

    kernel_request.listener:
        class: Giftshop\FrontBundle\Listener\KernelRequestListener
        arguments: [@entity_locale_setter.listener]
        tags:
            - { name: kernel.event_listener, method: onKernelRequest }

<?php
// KernelRequestListener.php

namespace Giftshop\FrontBundle\Listener;

use Symfony\Component\HttpKernel\Event\GetResponseEvent;

class KernelRequestListener
{

    private $entityLocaleSetter;

    public function __construct(EntityLocaleSetter $entityLocaleSetter)
    {
        $this->entityLocaleSetter = $entityLocaleSetter;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $this->entityLocaleSetter->setRequest($event->getRequest());
    }

}

@lennerd Forgot to thank you, your solution solved my problem!
