Sonata Admin: Want to create global configuration page

Question

I need to create signle global configuration page without list view, just single page with number of inputs like:

• fb page link
• google analytics id
• some default front-end texts
• checkbox options: show intro, show social media etc.

something that doesn't require to go through record listing, edit, save and return to list etc.

Do i need to create new controller with form and my own crud? Or is there a way to nicely connect/override sonata admin with that kind of panel?

I'm using:

• Symfony 2.3.X Latest
• Sonata cache 2.1.5
• Sonata block 2.2.7
• Sonata easy-extends 2.1.4
• Sonata admin 2.2.8
• Sonata doctrine-orm-admin 2.2.5
• Sonata jquery 1.8.*@dev
• Sonata intl 2.2.*@dev
• Sonata user 2.2.*@dev
• Sonata media 2.2.*@dev
• Sonata page 2.3.*@dev
• Sonata seo 1.1.*@dev
• Stof Doctrine Extensions Latest

EDIT

Following answer of pulzarraider and some more search i ended up with overriding listAction of CRUD controller.

In details, first created service definition (YML):

services:
    stack.admin.global_administration:
        class: Stack\Bundle\SiteBundle\Admin\GlobalConfigurationAdmin
        tags:
            - name: sonata.admin
              manager_type: orm
              group: Administration
              label: Global Configuration
        arguments:
            - ~
            - ~
            - StackSiteBundle:GlobalConfiguration

Then created Admin class for this specific action:

<?php
namespace stack\Bundle\SiteBundle\Admin;

use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Route\RouteCollection;

class GlobalConfigurationAdmin extends Admin
{
    protected $baseRouteName = 'global-configuration';
    protected $baseRoutePattern = 'global-admin';

    protected function configureRoutes(RouteCollection $collection)
    {
        // notice removal of create action!
        $collection->remove('create');
    }
}
?>

And finally CRUD controller to display custom form instead of default entity list action:

<?php 
namespace Stack\Bundle\SiteBundle\Controller;

use Sonata\AdminBundle\Controller\CRUDController as Controller;
use Symfony\Component\HttpFoundation\Request;

class GlobalConfigurationController extends Controller
{
    public function listAction()
    {
        if (false === $this->admin->isGranted('LIST')) {
            throw new AccessDeniedException();
        }

        // custom code here...

        return $this->render('StackSiteBundle:Administration:configuration-view.html.twig', array(
            'action' => 'list',
            'csrf_token' => $this->getCsrfToken('sonata.batch')
        ));
    }
}
?>

Thanks for help with this one!

Yes, it`s possible in Sonata Admin by overloading default CRUD controller.

You must create custom controller and overload editAction. In editAction you can create standard Symfony form, process the data from user and save it anywhere you want.
