我正在尝试使用symfony上传我的数据库中的文件，我修改了我的实体和我的表单。但是当我点击上传文档时，我没有任何错误，但没有任何附加内容（我在C：\ wamp64 \ www \ myproject \ web \ upload中没有新文档，而我的数据库字段，此处为support，为null）。这是我的实体的代码：

多谢
编辑：这是我的控制器的代码（创建表单时）和我在树枝上调用它的地方：
$em = $this->getDoctrine()->getManager();
$invoice = $em->getRepository("MainConfigBundle:InvoiceCoach")->find($id);
$formUpload = $this->createForm('invoicesupport', $invoice)
->add('save', 'submit', array('label' => 'Enregistrer') );
if($request->getMethod() == "POST"){
$formUpload->handleRequest($request);
if($formUpload->isValid()){
$em->persist($invoice);
$em->flush();
}
return $this->redirect($this->generateUrl('coach_paid_edit', array('id' => $id) ));
}
树枝：
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Upload facture</h5>
</div>
<div class="modal-body">
{{ form_start(form, {'attr': {'novalidate': 'novalidate', 'data-parsley-validate':'data-parsley-validate'}}) }}
{{ form_row(formUpload.file) }}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Fermer</button>
{{ form_row(formUpload.save) }}
{{ form_end(form) }}
</div>
</div>
首先也是最重要的 - 你是否测试过“特定于学说的方法”的问题？我的猜测是他们没有开火（老实说，我看到这样的第一次接近 - 而且我不知道它为什么要起作用）
即使 - 我认为这种方法很糟糕，这段代码应该转移到事件监听器/订阅。它不应该在实体文件中。
看看http://symfony.com/doc/current/doctrine/event_listeners_subscribers.html
