Symfony and Database - symfony

Question

I just make my 2 entity, one is Article and one is Commento, that are comments.
I want a comment form in every single article, so I created the 2 entity, the action in the controller, and the template.

</form>
</div>
</p>
</article>
{% endblock %}
So, the problem is that when you insert a comment in the form, and I submit the form, I get an error, even if the data are now saved in the db.
Only one data (article_id) that is a Commento's parameter, is NULL, and I don't know why.
This is the error:
No route found for "GET /singlearticle" (from
"http://local/Sito/web/app_dev.php/singlearticle/1")

Answer 1

You need a refactor to the two actions from controller:
public function singlearticleAction($id)
{
//Codice di singlearticle
$art = $this->getDoctrine()->getEntityManager();
$article = $art->getRepository('AppBundle:Article')->find($id);
if (!$article){
throw $this->createNotFoundException('Non riesco a trovare questo articolo!');
}
//Fin qui
$form = $this->createForm(new CommentoType($article), new Commento());
return $this->render('default/singlearticle.html.twig', array(
'article' => $article,
'form' => $form->createView())
);
}
public function inserisci_commentoAction(Request $request, $articleId)
{
//Codice di singlearticle
$em = $this->getDoctrine()->getEntityManager();
$article = $em->getRepository('AppBundle:Article')->find($articleId);
if (!$article) {
throw $this->createNotFoundException('Non riesco a trovare questo articolo!');
}
$commento = new Commento();
$form = $this->createForm(new CommentoType($commento), $commento);
$form->handleRequest($request);
if ($form->isValid())
{
try
{
$commento->setData(new \DateTime('now'));
$commento->setArticle($article);
$em->persist($commento);
$em->flush();
// add a success message to session flashbag
} catch (\Exception $e)
{
// add a error message to session flashbag
}
}
return $this->redirect($this->generateUrl('singlearticle', array('id'=> $articleId)));
}
The route definition for inserisci_commento needs to be changed to:
inserisci_commento:
path: /singlearticle/{articleId}/inserisci_commento
defaults: {_controller: AppBundle:Default:inserisci_commento}
And in twig replace {{ path('inserisci_commento',{id:commento.id}) }} with {{ path('inserisci_commento',{articleId: article.id}) }}
Hope this helps

Answer 2

The problem is in your redirect statement. You need to pass in the article id.
return $this->redirect('singlearticle',array('id' => $article->getId());

Answer 3

whats definetly wrong is the mappedBy attribute in article class
/**
* #ORM\OneToMany(targetEntity="Commento", mappedBy="commento")
*/
protected $commento;
must be
/**
* #ORM\OneToMany(targetEntity="Commento", mappedBy="article")
*/
protected $commento;
and you have a typo in inversedBy attribute in comment class
/**
*#ORM\ManyToOne(targetEntity="Article",inversedBy="commenti")
* #ORM\JoinColumn(name="article_id",referencedColumnName="id")
*/
protected $article;
must be
/**
*#ORM\ManyToOne(targetEntity="Article",inversedBy="commento")
* #ORM\JoinColumn(name="article_id",referencedColumnName="id")
*/
protected $article;
