Symfony4 bundle creation - impossible to generate a config file

Question

A code demo from this problem is visible on : GitHub and Packagist, please consult v0.0.3.

My problem : I want to generate a config\packages\owner_test.yaml file when I run :

composer require owner/test-bundle:0.0.3

But Composer display an error :

There is no extension able to load the configuration for "owner_test" (in "C:\Users\USER\PROJECT\vendor\owner\test-bundle\DependencyInjection/../Resources/config\owner_test.yaml"). Looked for namespace "owner_test", found "none".

Root key and bundle name is corrects and I have read all documentation finded, but nothing is right :

• https://symfony.com/doc/4.4/bundles/configuration.html
• https://symfony.com/doc/4.4/bundles/extension.html

Thanks for help

Here is a working example: https://github.com/cerad/bundle4

The bundle source is in the src-owner directory

What you are missing and perhaps not fully understanding is the bundle's Configuration class:

namespace Owner\TestBundle\DependencyInjection;

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

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder('owner_test');
        $treeBuilder->getRootNode()
            ->children()
                ->booleanNode('isDisplay')->defaultTrue()->end()
                ->booleanNode('someBoolean')->defaultTrue()->end()
            ->end()
        ;
        return $treeBuilder;
    }
}

The Configuration class is used to setup default config values for your bundle. These values can be overridden at the application level via a config/packages/owner_test.yaml. Your bundle will not have it's own config yaml file. Things just don't work that way.

Your extension then becomes:

namespace Owner\TestBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;

class OwnerTestExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        // Has what is in config/packages/owner_test.yaml
        dump($configs);

        $configuration = new Configuration();

        $config = $this->processConfiguration($configuration, $configs);
        dump($config);

        // At this point you would use $config to define your parameters or services

    }
}

Study the dump outputs and read the docs until you understand what is happening as the config is processed. Just use "bin/console cache:clear". I added a second config value just to make it a bit easier to understand. You will probably want to add more.

At this point it up to you to add code to transfer your config values to the ContainerBuilder.
