Configuring a standalone bundle

If you want a standalone bundle, eventually published for composer, and deployed in your vendor directory, you can incorporate the configuration of your DemoAdmin component within the bundle. Here is an example taken from the libre-informatique/crm-bundle :

<?php
// vendor/libre-informatique/crm-bundle/DependencyInjection/LibrinfoCRMExtension.php
namespace Librinfo\CRMBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
use Librinfo\CoreBundle\DependencyInjection\LibrinfoCoreExtension;

/**
 * This is the class that loads and manages your bundle configuration
 *
 * To learn more see {@link http://symfony.com/doc/current/cookbook/bundles/extension.html}
 */
class LibrinfoCRMExtension extends LibrinfoCoreExtension
{
    /**
     * {@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('admin.yml');
        
        $this->mergeParameter('librinfo', $container, __DIR__.'/../Resources/config');
    }
}

Then create a Resources/config/librinfo.yml file in your bundle, matching the previous specifications.

You'll notice the use Librinfo\CoreBundle\DependencyInjection\LibrinfoCoreExtension;, the class LibrinfoCRMExtension extends LibrinfoCoreExtension and the $this->mergeParameter('librinfo', $container, __DIR__.'/../Resources/config'); that loads the new configuration file, overloading the configuration of the parent bundle (here, Librinfo\CoreBundle).

Keeping the original/default SonataAdmin configuration (fields)

In fact when you generate an Admin component, it comes with the full list of fields representing the object you want to create/edit/list/show... So if you want, for any reason, to keep this configuration available, the best practice with Librinfo\CoreBundle is to extend this Admin component as: DemoAdmin -> DemoAdminConcrete.

<?php
// src/AcmeBundle/Admin/DemoAdminConcrete.php
namespace AcmeBundle\Admin;

use Librinfo\CoreBundle\Admin\Traits\Base as BaseAdmin;

class DemoAdminConcrete extends DemoAdmin
{
    use BaseAdmin;
}

Then to use your *AdminConcrete class, simply change your services file as:

# app/config/services.yml
services:
# ...
    app.admin.demo:
        class: AcmeBundle\Admin\DemoAdminConcrete
        # ...
