symfony - 在 createForm (Symfony 2) 中插入实体

Question

我找了几天来找到解决方案。我不能在 createForm 中传递我的实体，但只有当我传递实体特定的 getter 时它才有效

不工作：

$storyboard = $this->getDoctrine()
            ->getRepository('TutoAppBundle:Storyboard')
            ->find($id_screen);

$formSettings = $this->createForm( new MosaicCorporateCastType( ), $storyboard );

不工作：

    $storyboard = $this->getDoctrine()
            ->getRepository('TutoAppBundle:Storyboard')
            ->find($id_screen);

$formSettings = $this->createForm( new MosaicCorporateCastType( ), $storyboard->getPosition() );

在职的：

    $storyboard = $this->getDoctrine()
            ->getRepository('TutoAppBundle:Storyboard')
            ->find($id_screen);

$formSettings = $this->createForm( new MosaicCorporateCastType( ), $storyboard->getSettings() );

我试图理解为什么......如果你有任何建议，我很高兴。

谢谢您的帮助
