Symfony 3.4 Use view inside my bundle - php

Question

I've some trouble for the configuration of a new repository using Symfony 3.4. I've used the symfony command for create him with last LTS (3.4) and I add a new Bundle using command too. My new Bundle is up and work well but I can't use view stored inside this bundle.
I show you the structure of my Bundle :
I want to use this index.html.twig in my controller like this :
<?php
namespace Lister\ListerBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
class DefaultController extends Controller
{
/**
* #Route("/lister")
*/
public function indexAction()
{
return $this->render('ListerListerBundle:Default:index.html.twig');
}
}
But when I try to render it I've this error.
Unable to find template "ListerListerBundle:Default:index.html.twig" (looked into: /home/emendiel/Data/Code/Perso/WebLister/app/Resources/views, /home/emendiel/Data/Code/Perso/WebLister/vendor/symfony/symfony/src/Symfony/Bridge/Twig/Resources/views/Form).
I understand what that say, my folder is not where symfony search my view but I don't found how I can said to Symfony go in "ListerBundle/Ressources/views"
In my oldest project that was work without other configuration.
Info: I use my bundle as reusable bundle.
Regards,
PS: This is my autoload part in composer.json
"autoload": {
"psr-4": {
"": "src/"
},
"classmap": [
"app/AppKernel.php",
"app/AppCache.php"
]
},
PSS: My AppKernel :
public function registerBundles()
{
$bundles = [
new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
new Symfony\Bundle\SecurityBundle\SecurityBundle(),
new Symfony\Bundle\TwigBundle\TwigBundle(),
new Symfony\Bundle\MonologBundle\MonologBundle(),
new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
new AppBundle\AppBundle(),
new Lister\ListerBundle\ListerListerBundle(),
];
...
And Again: Here My dependencyInjection
And the content of files :
Configuration.php
<?php
namespace Lister\ListerBundle\DependencyInjection;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;
/**
* This is the class that validates and merges configuration from your app/config files.
*
* To learn more see {#link http://symfony.com/doc/current/cookbook/bundles/configuration.html}
*/
class Configuration implements ConfigurationInterface
{
/**
* {#inheritdoc}
*/
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('lister_lister');
// Here you should define the parameters that are allowed to
// configure your bundle. See the documentation linked above for
// more information on that topic.
return $treeBuilder;
}
}
ListerListerExtension.php
<?php
namespace Lister\ListerBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
/**
* This is the class that loads and manages your bundle configuration.
*
* #link http://symfony.com/doc/current/cookbook/bundles/extension.html
*/
class ListerListerExtension extends Extension
{
/**
* {#inheritdoc}
*/
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('services.yml');
}
}
Solution: from #Cerad
#ListerLister/Default/index.html.twig
Original response from #Cerad
For some reason, S3.4 no longer likes the Bundle:Dir:name approach to specifying twig paths and the generate:bundle command has not yet been updated. Not sure if it is a bug or feature. The #ListerLister/Default/index.html.twig path suggested above should work. Try bin/console debug:twig to see your twig namespaces paths. – Cerad

Answer 1

The basic problem appears to be that in S3.4, twig template paths such as 'ListerListerBundle:Default:index.html.twig' are no longer supported.
Replace the path in the controller with:
'#ListerLister/Default/index.html.twig'
And all should be well. If you are ever not sure what the actual namespace prefix is then run:
bin/console debug:twig
to list them.
S3.3 still works fine so this is something that changed in 3.4. Supposed to be using the namespaced format anyways so this is not a big deal.
I did file an issue about this on github: https://github.com/sensiolabs/SensioGeneratorBundle/issues/587
We shall see what the maintainers have to say.
Update: The great and powerful Fabpot himself replied to my issue. If you want to keep using the 'ListerListerBundle:Default:index.html.twig' format for templates then edit your app/config/config.yml file:
# app/config/config.yml
framework:
templating:
engines: ['twig']
You should only do this if you have legacy code which still uses the old format. Use twig namespaces for all new code.

#config/config.yml
#after router add like
router:
resource: '%kernel.project_dir%/app/config/routing.yml'
strict_requirements: ~
templating:
engines: [twig]
