Symfony2 bundle configuration issue - php

Question

I am trying to expose a custom configuration defined for my bundle which is called DecisionBundle.
I have a Decision\DecisionBundle\Resources\config\custom.yaml that looks like this:
decision:
testValue: 11
anotherTest: 12
I also have an Extension that looks like this:
namespace Decision\DecisionBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
class DecisionExtension 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');
$loader->load('custom.yml');
}
}
The file custom.yml seems to be loaded ok. Next comes the configuration interface
namespace Decision\DecisionBundle\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('decision');
$rootNode
->children()
->scalarNode('testValue')->defaultValue('0')->end()
->scalarNode('anotherTest')->defaultValue('0')->end()
->end();
// 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;
}
}
However, this results in the following:
InvalidArgumentException: There is no extension able to load the configuration for "decision" (in *****\src\Decision\DecisionBundle\DependencyInjection/../Resources/config\custom.yml). Looked for namespace "decision", found none
Can somebody point me as to what I am doing wrong? Do I need to manually register the Extension somehow? However, the Extension seems taken into account as it looks loaded from the debug info.
Thanks!

Currently you are setting parameters in your custom.yml file in the same way that you would set them in the `app/config/config.yml' file.
decision:
testValue: 11
anotherTest: 12
When you are loading a file through the configuration file then your service files (services.yml & custom.yml in your case) should have either services or parameters as the headers. To use your parameters in the custom.yml file you should lay it out like..
parameters:
decision.testValue: 11
decision.anotherTest: 12
Also, if you are putting the parameters in the app/config/config.yml file, you need to set them to actual parameters in your DecisionExtension. To do this you would need to get the data from your Configuration file and set them in the container like..
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new
FileLocator(__DIR__.'/../Resources/config'));
$loader->load('services.yml');
$loader->load('custom.yml');
$container->setParameter('decision.testValue', $config['testValue']);
$container->setParameter('decision.anotherTest', $config['anotherTest']);
This, however, will overwrite the parameters set in your custom.yml and also negate any reason for it being there.
