lost current local language after login and after logout - php

Question

i can switch language of my web site correctly but when i log in, i lost my current language in the url. for exemple before login http://test.bu/app_dev.php/en/admin/slideshow/ and after login i have this http://test.bu/app_dev.php/fr/admin/slideshow/
symfony2.7 takes always locale: fr. i use FosUserBundle. i ggogled i find that i can use bundles to fix this but i think i can resolve this by editing confinguration.
after login i redirect the web site by the default_target_path: slideshow_index like this
app_slideshow:
resource: "#AppBundle/Resources/config/routing/slideshow.yml"
prefix: /{_locale}/admin/slideshow
this is my config.yml
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: services.yml }
# Put parameters here that don't need to change on each machine where the app is deployed
# https://symfony.com/doc/current/best_practices/configuration.html#application-related-configuration
parameters:
locale: fr
framework:
#esi: ~
translator: { fallback: %locale% }
secret: '%secret%'
router:
resource: '%kernel.root_dir%/config/routing.yml'
strict_requirements: ~

validation: { enable_annotations: true }
#serializer: { enable_annotations: true }
templating:

default_locale: '%locale%'
trusted_hosts: ~

session:
# handler_id set to null will use default session handler from php.ini

# if using pdo_sqlite as your database driver:
# 1. add the path in parameters.yml

# 2. Uncomment database_path in parameters.yml.dist

Link of JMS routing bundle https://github.com/schmittjoh/JMSI18nRoutingBundle
But before you install it please look at this short video tutorial. This tutorial helped me a lot to understand the problem you are having between fos user bundle and the locale in url.
https://codereviewvideos.com/course/getting-started-with-fosuserbundle/video/translations-and-internationalisation-in-fosuserbundle
If you don't want to install jms routing bundle with your composer.json file you can install it with this command php composer.phar require jms/i18n-routing-bundle "dev-master"
Here is my config:
jms_i18n_routing:
default_locale: "%locale%"
locales: ["fr", "en"]
strategy: prefix_except_default
Security.yml:
firewalls:
main:
pattern: ^/
form_login:
provider: fos_userbundle
csrf_token_generator: security.csrf.token_manager
require_previous_session: false
login_path: fos_user_security_login
check_path: fos_user_security_check
default_target_path: your_route_name_homepage
logout:
path: fos_user_security_logout
target: your_route_name_homepage
anonymous: true
access_control:
- { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY && !IS_AUTHENTICADED_FULLY }
- { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY && !IS_AUTHENTICADED_FULLY }
- { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/, role: ROLE_ADMIN }
After having installed Jms routing bundle. Try to execute the commande debug/router (symfony 3) and watch the routes names and prefix.

You can handle the locale detection/switch with JMSI18nRoutingBundle
Add the required bundles to composer.json:
"require": {
...
"jms/i18n-routing-bundle": "1.1.*",
"jms/translation-bundle": "1.1.*",
"friendsofsymfony/user-bundle": "1.3.*"
},
