Symfony 2 - configuration to Command Container

Question

I have defined in app/config.yml sample:

module_my_module
   key: value1
   key2: value2

And a bundle with DependecyInjection Configuration.php:

<?php

namespace Modules\Bundle\MyModuleBundle\DependencyInjection;

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('module_configuration');
        $rootNode->children()
                ->scalarNode('key')->defaultValue('')->end()
                ->scalarNode('key2')->defaultValue('')->end()
            ->end()
            ;

        return $treeBuilder;
    }
}

A problem is how to call config.Bundle/Command class:

namespace Modules\Bundle\MyBundle\Command;

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;

//use \Modules\Bundle\NodeSocketBundle\DependencyInjection as DependencyInjection;

class MyCommand extends ContainerAwareCommand
{

    protected function execute(InputInterface $input, OutputInterface $output)
    {
    $this->getParams("key.val"); // GEt a key from config.yml
    }

}

Config.yml:

module_configuration
     key:  val

In a ContainerAwareCommand you can access to params as $this->getContainer()->getParameter("param_name") — Matteo

You must inject your params in the Container in the Extension Bundle Class definition.

In your case you must have something similar to:

<?php

namespace Modules\Bundle\MyModuleBundle\DependencyInjection;


class MyModuleExtension 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('...');

        $container->setParameter('my_first_key', $config['key']);
        $container->setParameter('my_second_key', $config['key2']);

    }
}

Then you can access to the value, in your Commandclass as:

class MyCommand extends ContainerAwareCommand
{

    protected function execute(InputInterface $input, OutputInterface $output)
    {
    $this->getContainer()->getParameter("my_first_key");
    }

}

Hope this help
