我正在尝试更新具有文件字段的配方实体，特别是图像。
这是我的实体

在控制器中我有更新动作
这是控制器行动
public function update_ricettaAction(Request $request, $id)
{
//$this->denyAccessUnlessGranted('ROLE_ADMIN', null, 'Non puoi accedere a questa pagina!');
$em = $this->getDoctrine()->getManager();
$recipe = $em->getRepository('AppBundle:Recipe')->find($id);
$form = $this->createForm(new RecipeType($recipe), $recipe);
$form->handleRequest($request);
if ($form->isValid())
{
$em = $this->getDoctrine()->getManager();
try
{
$em->persist($recipe);
$em->flush();
return $this->redirect($this->generateUrl('successricettaupdate'));
} catch (\Exception $e)
{
$form->addError(new FormError('errore nel database: ' . $e->getMessage()));
}
if ($form->isValid())
{
$var = $recipe;
$em->persist($var);
$em->flush();
return $this->redirect($this->generateUrl('successricettaupdate'));
} else
{
}
}
return $this->render('administration/update_ricetta.html.twig', array(
'recipe' => $recipe,
'form' => $form->createView()));
}
当我提交表单时，要更新实体的全部，部分或仅一个字段，我会收到错误：
错误：在非对象上调用成员函数move（）
我不知道它能是什么...... 有什么建议吗？
答案 0 :(得分：0)
<强>解决
我解决了自己的问题，如果可以帮助任何人，这就是解决方案：
在实体中，我对此进行了修改：
/**
* @ORM\PrePersist()
* @ORM\PreUpdate()
*/
public function uploadImage() {
// the file property can be empty if the field is not required
if (null === $this->image) {
return;
}
if(!$this->id){
$this->image->move($this->getTmpUploadRootDir(), $this->image->getClientOriginalName());
}else{
$this->image->move($this->getUploadRootDir(), $this->image->getClientOriginalName());
}
$this->setImage($this->image->getClientOriginalName());
}
到此：
/**
* @ORM\PrePersist()
* @ORM\PreUpdate()
*/
public function uploadImage() {
// the file property can be empty if the field is not required
if (null === $this->image) {
return;
}
if(!$this->id){
$this->image->move($this->getTmpUploadRootDir(), $this->image->getClientOriginalName());
}else{
return null;
}
}
现在我没有收到任何错误，更新有效！
