从其他包中嵌入Symfony控制器

Question

This seems to be an interesting issue, and I'm not sure if I'm missing something because it should be simple, but isn't.

Scenario

1. I have one bundle named AcmePageBundle
2. Another bundle named AcmeGalleryBundle
3. I want to load an embedded view from the controller using the AcmeGalleryBundle bundle into a template file on AcmePageBundle

Code

AcmeGalleryBundle\Controller\DisplayController.php

class DisplayController extends Controller
{
    public function embedAction($galleryId)
    {
        $gallery = $this->getDoctrine()->getRepository('AcmeGalleryBundle')->find($galleryId);
        if (!$gallery) {
            throw $this->createNotFoundException('Gallery could not be found');
        }

        return $this->render('AcmeGalleryBundle:Display:embed.html.twig', array(
            'gallery' => $gallery,
        ));
    }
}

AcmeGalleryBundle\Resources\views\Display\embed.html.twig

  <div class="gallery">
  {% for photo in gallery.photos %}
    <a href="{{ photo.webPath }}" rel="shadowbox[gallery];">
      <img src="{{ photo.webPath }}" height="100" width="100">
    </a>
  {% endfor %}
  </div>

AcmePageBundle\Resources\views\Default\index.html.twig

{# ... extra HTML content #}
  <h2>Gallery</h2>
  {{ render(controller('AcmeGalleryBundle:Display:embed', {
      'galleryId': 123
  })) }}
{# rest of the HTML content #}

Errors

When trying to render the page that uses AcmePageBundle:Default:index.html.twig, I get

An exception has been thrown during the rendering of a template ("Class 'AcmeGalleryBundle' does not exist") in AcmePageBundle:Default:index.html.twig at line 18.

but of course, AcmeGalleryBundle does in fact exist. I'm suspecting a scope problem that I've missed somewhere.

Troubleshooting

1. Ensured that AcmeGalleryBundle is loaded in the AppKernel.php file
2. Tried adding use Acme\GalleryBundle to the top of the AcmePageBundle.php bundle file.
3. Found an issue on GitHub relating to the problem with no response from the devs yet. I've added my own comments - this may in fact be a bug.

Am I missing anything obvious?

Answer 1

My mistake was in this line:

$gallery = $this->getDoctrine()->getRepository('AcmeGalleryBundle')->find($galleryId);

The command getRepository('AcmeGalleryBundle') needs to include the entity I'm trying to load the repository for in question. Correct code is:

$gallery = $this->getDoctrine()->getRepository('AcmeGalleryBundle:Gallery')->find($galleryId);

I mistakenly thought this was an issue with the render(controller(...)) functionality. After that fix, everything works as it should. Next time I should be looking closer at my stack trace!
