Sonata admin bundle, manipulate objects - symfony

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 is my project entity:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Projet
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="AppBundle\Entity\ProjetRepository")
*/
class Projet
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nom", type="string", length=255)
*/
private $nom;
/**
* #var string
*
* #ORM\Column(name="description", type="string", length=255)
*/
private $description;
/**
* #var \DateTime
*
* #ORM\Column(name="dateCreation", type="date")
*/
private $dateCreation;
/**
* #ORM\OneToMany(targetEntity="AppBundle\Entity\Prototype", mappedBy="projet",cascade={"persist"} , orphanRemoval=true)
* #ORM\OrderBy({"id"="ASC"})
*/
protected $prototypes;
public function __construct()
{
$this->prototypes = new \Doctrine\Common\Collections\ArrayCollection();
$this->dateCreation = new \DateTime("now");
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set nom
*
* #param string $nom
* #return Projet
*/
public function setNom($nom)
{
$this->nom = $nom;
return $this;
}
/**
* Get nom
*
* #return string
*/
public function getNom()
{
return $this->nom;
}
public function __toString()
{
return $this->getNom();
}
/**
* Set description
*
* #param string $description
* #return Projet
*/
public function setDescription($description)
{
$this->description = $description;
return $this;
}
/**
* Get description
*
* #return string
*/
public function getDescription()
{
return $this->description;
}
/**
* Set dateCreation
*
* #param \DateTime $dateCreation
* #return Projet
*/
public function setDateCreation($dateCreation)
{
$this->dateCreation = $dateCreation;
return $this;
}
/**
* Get dateCreation
*
* #return \DateTime
*/
public function getDateCreation()
{
return $this->dateCreation;
}
public function setPrototypes($prototypes)
{
if (count($prototypes) > 0) {
foreach ($prototypes as $i) {
$this->addPrototypes($i);
}
}
return $this;
}
/**
* Add prototypes
*
* #param \AppBundle\Entity\Prototype $prototypes
* #return Projet
*/
public function addPrototypes(\AppBundle\Entity\Prototype $prototypes)
{
$this->prototypes[]= $prototypes;
return $this;
}
public function addPrototype(\AppBundle\Entity\Prototype $prototype)
{
$prototype->setProjet($this);
$this->prototypes->add($prototype);
}
/**
* Remove prototypes
*
* #param \AppBunble\Entity\Prototype $prototypes
*/
public function removePrototypes(\AppBundle\Entity\Prototype $prototypes)
{
$this->prototypes->removeElement($prototypes);
}
/**
* Get prototypes
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getPrototypes()
{
return $this->prototypes;
}
}
and here is my prototype entity
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Prototype
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="AppBundle\Entity\PrototypeRepository")
*/
class Prototype
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nom", type="string", length=255)
*/
private $nom;
/**
* #var string
*
* #ORM\Column(name="description", type="string", length=255)
*/
private $description;
/**
* #var \DateTime
*
* #ORM\Column(name="dateCreation", type="date")
*/
private $dateCreation;
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\Projet", inversedBy="prototypes")
* #ORM\joinColumn(name="projet_id", referencedColumnName="id")
*/
private $projet;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Get nom
*
* #return string
*/
public function getNom()
{
return $this->nom;
}
public function __toString()
{
return $this->getNom();
}
/**
* Set nom
*
* #param string $nom
* #return Prototype
*/
public function setNom($nom)
{
$this->nom = $nom;
return $this;
}
/**
* Set description
*
* #param string $description
* #return Prototype
*/
public function setDescription($description)
{
$this->description = $description;
return $this;
}
/**
* Get description
*
* #return string
*/
public function getDescription()
{
return $this->description;
}
/**
* Set dateCreation
*
* #param \DateTime $dateCreation
* #return Prototype
*/
public function setDateCreation($dateCreation)
{
$this->dateCreation = $dateCreation;
return $this;
}
/**
* Get dateCreation
*
* #return \DateTime
*/
public function getDateCreation()
{
return $this->dateCreation;
}
/**
* Set projet
*
* #param \AppBundle\Entity\Projet $projet
* #return Prototype
*/
public function setProjet(\AppBundle\Entity\Projet $projet = null)
{
$this->projet = $projet;
return $this;
}
/**
* Get projet
*
* #return \AppBundle\Entity\Projet
*/
public function getProjet()
{
return $this->projet;
}
}
In my projetAdmin I can show in the ShowAction the prototypes :
here is projetAdmin :
<?php
namespace AppBundle\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Show\ShowMapper;
use Sonata\AdminBundle\Route\RouteCollection;
class ProjetAdmin extends Admin
{
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('nom', 'text', array('label' => 'Nom'))
->add('description','text',array('label'=>'Description'))
->add('dateCreation', 'date', array('label' => 'Date de création'))
;
}
protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
$datagridMapper
->add('nom')
->add('dateCreation')
;
}
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->add('nom')
->add('description')
->add('dateCreation')
->add('_action', 'actions', array(
'actions' => array(
'show' => array(),
'edit' => array(),
'delete' => array(),
)
)
)
;
}
protected function configureShowFields(ShowMapper $showMapper)
{
$showMapper
->add('prototypes')
;
}
}
I get the prototypes ( names )
But I would like to "list" the prototypes that belong to the project like the list view ( name , description of the prototype...)
How can I do that ?

Answer 1

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 %}

Answer 2

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.
