使用Symfony编辑实体中的文件名 [英] Edit file name in entity with Symfony
问题描述
你好（对不起，我的英语不太好）
我实际上是在一个展示一些眼镜的Symfony网站上工作的信息。
现在，我需要在创建其中一个图像时添加图像。我设法借助 此 教程。
I'm actually working on a Symfony website that display some spectacles' information. For now, I need to add an image when I create one of them. I managed to do so with the help of this tutorial.
基本上是这样的：我将图片上传到网站目录中，然后将文件名发送给实体（存储在MySQL数据库中）。然后，我可以在眼镜的详细信息中显示图像。
It basically works like this: I upload an image into site's directory and then send file's name to the entity (Store in a MySQL database). I can then display the image in spectacle's details.
我要编辑眼镜时出现了问题。我无法更新图片的名称。我只有两种可能性：1 /不编辑实体，或者2 /更改图像名称，然后得到一个我不再显示的随机图像（这些名称通常像 / tmp / phpWb8kwV ）
The issue appeared when I want to edit a spectacle. I can't update the image's name. I have two only possibilities are to 1/not edit the entity, or to 2/change the image name and then get a random one that I can't display anymore (these names are usually like /tmp/phpWb8kwV)
我的图像在实体（在Spectacle.php中）这样的实例化：：
/**
* @var string
*
* @ORM\Column(name="image", type="string", length=255)
* @Assert\NotBlank(message="Veuillez ajouter une image à votre spectacle.")
* @Assert\File(mimeTypes={ "image/png" })
*/
private $image;
然后眼镜形式的FormType就是这样（在SpectacleType.php中）：
And the FormType for the spectacle's form is made like this (in SpectacleType.php):
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('nom')
->add('lieu')
->add('dateSpectacle', null, array(
'label' => 'Date du spectacle',
))
->add('annee')
->add('image',FileType::class, array(
'label' => 'Image du spectacle',
'required' => false, //(Still need to provide a file to finalize the creation/edit)
));
}
访问此页面的控制器是这样的（in SpectacleController.php）：
And the controller to acces this page is made like this (in SpectacleController.php):
/**
* Creates a new spectacle entity.
*
* @Route("/new", name="admin_spectacle_new")
* @Method({"GET", "POST"})
*/
public function newAction(Request $request)
{
$spectacle = new Spectacle();
$form = $this->createForm('FabopBundle\Form\SpectacleType', $spectacle);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
//--------------------------------------------------------------------
$file = $spectacle->getImage();
$fileName = (md5(uniqid())).'.'.$file->guessExtension();
// moves the file to the directory where image are stored
$file->move(
$this->getParameter('img_directory'), //(Define in the service.yml)
$fileName
);
$spectacle->setImage($fileName); //(Don't know how to handle file names without this line)
//---------------------------------------------------------------------
$em->persist($spectacle);
$em->flush();
return $this->redirectToRoute('admin_spectacle_show', array('id' => $spectacle->getId()));
}
return $this->render('spectacle/new.html.twig', array(
'spectacle' => $spectacle,
'form' => $form->createView(),
));
}
路由到编辑视图的函数大致相同，但是我不能使用
The function that is routed to the edit view is approximatively the same, but i can't use
$spectacle->setImage($fileName);
有两种方法可以解决此问题：例如能够更新实体中的新文件名（以及其他信息），或者能够在不更改文件名的情况下更新实体。
There is two possibilities to solve this: I would like being able to update the new filename in the entity (with the other information) or being able to update the entity without changing filename.
我希望我足够清楚解释我的问题...
预先感谢您的答复。
I hope I was clear enough to explain my problem... Thanks in advance for your responses.
推荐答案
解决方案很愚蠢...
The solution was stupid ...
实际上，用于访问 edit 路线的控制器没有以下行：
In fact, the controller to access the edit route didn't have those lines:
$em = $this->getDoctrine()->getManager();
...
$em->persist($spectacle);
$em->flush();
我需要快速完成此操作。如果我以后有更多时间，我将尝试使其与ComurImageBundle一起使用。
I need to finish this quickly. If i have more time later, i'll try to make it work with the ComurImageBundle.
感谢您的帮助，我下次会更小心...
Thank you for your help, i'll be more carefull next time ...
