    <p>I'm facing some annoying problem with doctrine 2.</p> <p>I have a document entity and a conference entitiy.</p> <pre><code>/** * * @author klauss * * @ORM\Entity * @ORM\HasLifecycleCallbacks */ class Document { /** * @ORM\Id * @ORM\Column(type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ public $id; /** * @ORM\Column(type="string", length=255, nullable=true) */ public $path; /** * @ORM\OneToOne(targetEntity = "Conference", mappedBy = "image") */ protected $conference; /** * @Assert\File( * maxSize="4M", * maxSizeMessage="Allowed maximum size is {{ limit }}" * ) */ public $file; // ..... </code></pre> <p>And the Conference Entity</p> <pre><code>// ......... /** * Uploaded image. * * @ORM\OneToOne(targetEntity = "Document", inversedBy = "conference") * @ORM\JoinColumn(name = "image", nullable = true, referencedColumnName = "id") */ protected $image; // ............ </code></pre> <p>So in a Twig template I'd like to do the following:</p> <pre><code>{{ conference.image.path }} </code></pre> <p>But it just does not load the image, I always need to call</p> <pre><code>$conference-&gt;getImage()-&gt;getPath(); </code></pre> <p>in the PHP to get the correct path in Twig. But shouldn't that be the same? If I don't call it in PHP, the Twig call just returns an empty string</p> <p>How can I achieve that Doctrine automatically is aware of the Document relation?</p>

    1. COTry `{{ conference.getImage.getPath }}` in Twig just to be sure it calls the getters as it should. You can also search in `app/dev/cache` for the offending template name (something like search for `AcmeBundle:Conference:view.html.twig`) and check the resulting template code associated with your Twig template to see how it calls your object.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
