Delete record from embedded Form

[cartmanac]

Hi,

I have got a problem with embedded Forms in Symfony2 Doctrine2.

Adding forms and records works fine, but removing does not work.
I used this tutorial: http://symfony.com/doc/current/cookbook ... tions.html --> allowing tags to be removed

Error is --> Fatal error: Call to undefined method Xxx\XxxxBundle\Entity\Aktionen::removeElement() in ...

PLEASE HELP!!!!!


My DB:

Code: Select all

\Entity\Aktionen:
  type: entity

My editAction in "AktionenController" looks like this:

Code: Select all

public function editAction($id, Request $request)
    {
        $em = $this->getDoctrine()->getEntityManager();
        $entity = $em->getRepository('XxxXxxxBundle:Aktionen')->find($id);

        if (!$entity) {
            throw $this->createNotFoundException('Unable to find Aktionen entity.');
        }
       
        $request = $this->getRequest();
       
        $editForm = $this->createForm(new AktionenType(), $entity);
        $deleteForm = $this->createDeleteForm($id);   
       
        // Create an array of the current Tag objects in the database
       foreach ($entity->getAktionenProdukte() as $tag) $originalTags[] = $tag;
   
       $editForm = $this->createForm(new AktionenType(), $task);
   
       foreach ($entity->getAktionenProdukte() as $tag) {
                   foreach ($originalTags as $key => $toDel) {
                       if ($toDel->getAktion() === $tag->getId()) {
                           unset($originalTags[$key]);
                       }
                   }
               }
   
               // remove the relationship between the tag and the Task
               foreach ($originalTags as $tag) {
                   // remove the Task from the Tag
                   $tag->getAktion()->removeElement($entity);
   
                   // if it were a ManyToOne relationship, remove the relationship like this
                   // $tag->setTask(null);
   
                   $em->persist($tag);
   
                   // if you wanted to delete the Tag entirely, you can also do that
                   // $em->remove($tag);
               }
   
               $em->persist($entity);
               $em->flush();
   
               // redirect back to some edit page
               return $this->redirect($this->generateUrl('we_aktionen_edit', array('id' => $id)));
       
        return $this->render('XxxXxxxBundle:Aktionen:edit.html.twig', array(
            'entity'      => $entity,
            'edit_form'   => $editForm->createView(),
            'delete_form' => $deleteForm->createView(),
        ));
    }

removeElement() is ArrayCollection method:

Code: Select all

$tag->getAktionenProdukte()->removeElement($entity);
