Custom config in Symfony2 - php

Question

I develop a little bundle, that provides tag cloud functionality. It should be easy, to include it in other Symfony projects and therefore it needs to be configurable. I discovered 3 pages:
How to Create Friendly Configuration for a Bundle
Defining and Processing Configuration Values
How to Load Service Configuration inside a Bundle
I worked along the examples, but it's obvious, that I miss something, because I get the following error message when I use php app/console config:dump-reference:
[Symfony\Component\Config\Exception\FileLoaderLoadException]
There is no extension able to load the configuration for "loew_tag" (in somePath/blog/app/config/../../src/Loew/TagBundle/Resources/config/config.yml). Looked for namespace "loew_tag", found " ... " in somePath/blog/app/config/../../src/Loew/TagBundle/Resources/config/config.yml (which is being imported from "somePath/blog/app/config/config.yml").
and
[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]
There is no extension able to load the configuration for "loew_tag" (in /home/somePath/blog/app/config/../../src/Loew/TagBundle/Resources/config/config.yml). Looked for namespace "loew_tag", found "framework", "security", "twig", "monolog", "swiftmailer", "assetic", "doctrine", "sensio_framework_extra", "blog", "fos_user", "debug", "web_profiler", "sensio_distribution"
I work inside a 'blog bundle' and try to access the config data for the 'tag bundle'.
Top of my 'app/config/config.yml':
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: services.yml }
- { resource: ../../src/Loew/TagBundle/Resources/config/services.yml }
- { resource: ../../src/Loew/TagBundle/Resources/config/config.yml }
LoewTagExtension.php:
<?php
// Loew/TagBundle/DependencyInjection/LoewTagExtension.php
namespace Loew\TagBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
class LoewTagExtension extends Extension
{
/**
* {#inheritdoc}
*/
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
//$container->setParameter('food_entities', $config['food_entities']);
$container->setParameter('split_match', $config['split_match']);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('config.yml');
$loader->load('services.yml');
}
}
config.yml:
loew_tag:
# food_entities:
# - "BlogBundle:Article"
# - "BlogBundle:Comment"
split_match: "/[^0-9a-zA-ZöÖüÜäÄß]/"
Configuration.php:
<?php
// Loew/TagBundle/DependencyInjection/Configuration.php
namespace Loew\TagBundle\DependencyInjection;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;
class Configuration implements ConfigurationInterface
{
/**
* {#inheritdoc}
*/
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('loew_tag');
$rootNode
->children()
->scalarNode('split_match')->end()
// ->arrayNode('food_entities')
// ->prototype('scalar')->end()
->end();
return $treeBuilder;
}
}
Entries for the node food_entities are commented in all files to keep it as simple as possible.
I noticed, that similar questions has been asked and the regarding problems has been solved but I cannot transfer that solutions to this issue.
Any idea, what I do miss?

Answer 1

Finally solved this by
keeping naming conventions in mind, especially the part, pointed out by Jakub Zalas
removing entry: $loader->load('config.yml'); from the extension file.
Obviously, the config file will be loaded automatically as soon, as the service has been loaded.
