    copied!<p>When I upload a file to Symfony, it is uploads like it should. I have used the Symfony tutorial on file upload and modified it to fit my needs.</p> <pre><code>if($form-&gt;isValid()) { $em = $this-&gt;oStarter-&gt;getEntityManager(); // Save file to database $uploadedFile = new ProfilePicture(); $uploadedFile-&gt;setFile($formData["profile_picture"]); $user-&gt;setProfilePicture($uploadedFile); $uploadedFile-&gt;setUser($user); $em-&gt;persist($uploadedFile); $em-&gt;persist($user); $em-&gt;flush(); // Other things like Twig templates etc.. </code></pre> <p>This code is used to upload an image and set it as the user's profile picture. The user is found through <code>$this-&gt;getUser()</code> in the Controller. When I output the Entity after flushing, it shows me the dump of a valid Entity, like I would expect.</p> <p>When I visit the profile page for this user, the image was not found. When I check the MySQL table, I find a valid entry for the ProfilePicture with the correct ID and path. The user also has a reference to the ProfilePicture's ID, as you would expect. Instead, the page shows me the following dump:</p> <pre><code>$avatar = $user-&gt;getProfilePicture(); $path = $avatar-&gt;getWebPath(); Debug::dump($avatar); object(stdClass)#938 (8) { ["__CLASS__"]=&gt; string(42) "Takeabyte\CoreBundle\Entity\ProfilePicture" ["__IS_PROXY__"]=&gt; bool(true) ["__PROXY_INITIALIZED__"]=&gt; bool(false) ["id"]=&gt; NULL ["user"]=&gt; object(stdClass)#1011 (52) { ["__CLASS__"]=&gt; string(32) "Takeabyte\CoreBundle\Entity\User" ["id"]=&gt; int(11) // lots of user info } ["file"]=&gt; NULL ["path"]=&gt; NULL ["temp"]=&gt; NULL } </code></pre> <p>The dump shows that there is no path set. Even after calling a function of the Proxy, the real data seems not to be loaded. What am I doing wrong?</p> <p><strong>EDIT</strong> The entities are as follows:</p> <pre><code>/** * @author Tim Cocu * @author Rick Slinkman * * @ORM\Entity * @ORM\Table(name="profilepictures") * @Database(target="client") */ class ProfilePicture extends Image { /** * @ORM\Id * @ORM\Column(type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @ORM\OneToOne(targetEntity="\Takeabyte\CoreBundle\Entity\User", mappedBy="profilePicture") */ private $user; // accessors and mutators } /** * Description of Image * * @ORM\MappedSuperclass * @Database(target="client") * @author Rick Slinkman (r.slinkman@take-a-byte.eu) */ class Image extends MediaFile { /** * @param ClassMetadata $metadata */ public static function loadValidatorMetadata(ClassMetadata $metadata) { $metadata-&gt;addPropertyConstraint('file', new Assert\File(array( 'maxSize' =&gt; 6000000, 'mimeTypes' =&gt; array( "image/jpeg", "image/png", "image/gif" ), ))); } // other functions } /** * Standard container of an uploaded media file * @author Rick Slinkman * @author Tim Cocu * * @ORM\HasLifecycleCallbacks * @ORM\MappedSuperclass * @Database(target="client") * * Based on: * http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html */ class MediaFile { /** * @Assert\File(maxSize="6000000") */ protected $file; /** * @ORM\Column(type="string", length=255, nullable=true) */ protected $path; /** * Temporary storage on file moving. */ protected $temp; /** * @ORM\PrePersist() * @ORM\PreUpdate() */ public function preUpload() { if (null !== $this-&gt;getFile()) { // do whatever you want to generate a unique name $filename = sha1(uniqid(mt_rand(), true)); $this-&gt;path = $filename.'.'.$this-&gt;getFile()-&gt;guessExtension(); } } /** * @ORM\PostPersist() * @ORM\PostUpdate() */ public function upload() { if (null === $this-&gt;getFile()) { return; } // if there is an error when moving the file, an exception will // be automatically thrown by move().
