Sonata admin bundle, manipulate objects

Question

I have 2 entities with one to many relationship project and prototype And I\'ve been looking for a way to list the prototypes that belong to a project in the show action . here

Answer 1

I found a way to resolve the problem but still I feel it's not the better way I created a controller and overrided the showAction

<?php


namespace AppBundle\Controller;


use Sonata\AdminBundle\Route\RouteCollection;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
use Sonata\AdminBundle\Controller\CRUDController as Controller;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

class CRUDController extends Controller
{

    public function showAction($id = null)
    {
        return $this->redirect($this->generateUrl('admin_app_prototype_list', array(
        'filter[projet__id][value]'=>$id
    )));
    }
}

Then I get a list of prototypes that belong to a project.

Answer 2

One way is to define the template for your prototypes field in showMapper

protected function configureShowFields(ShowMapper $showMapper)
{
    $showMapper ->add('prototypes',null, array('template' => 'NamespaceYourBundle::Admin/prototypes.html.twig'));

}

Create Admin folder in your bundle's resources folder and create prototypes.html.twig file ,extend your twig template with sonata's base_show_field.html.twig template and in {% block field %} define your own markup looping through all related prototypes

{% extends 'SonataAdminBundle:CRUD:base_show_field.html.twig' %}
{% block field %}
    {% spaceless %}
        {% if object.getPrototypes() is not empty %}
            <table class="table table-bordered table-striped">
            <thead>
            <tr class="sonata-ba-list-field-header">
            <th class="sonata-ba-list-field-header-text">Nom</th>
            <th class="sonata-ba-list-field-header-text">Description</th>
                ...
                ...
                ...
            </tr>
            </thead>
            <tbody>
            {% for prototype in object.getPrototypes() %}
            <tr>
                <td class="sonata-ba-list-field sonata-ba-list-field-text">{{ prototype.getNom() }}</td>
                <td class="sonata-ba-list-field sonata-ba-list-field-text">{{ prototype.getDescription() }}</td>
                ...
                ...
                ...
            </tr>
            {% endfor %}
            </tbody>
            </table>
        {% endif %}
    {% endspaceless %}
{% endblock %}
