Symfony验证作为实体中的注释：什么是错误？

验证没有反应并阻止提交。 有人能告诉我遗漏了什么或者我做错了什么吗？ 显然，当调用方法isValid时，验证器会阻止验证。 在实体中，此变量的验证如下所示： /** *@var字符串 *@Assert\NotBlank（） */ 私人$pGaWeeks

提交会被阻止，无论是给变量pGaWeeks还是保留为空。 没有出现任何错误消息。当从代码中删除“@Assert\NotBlank（）”时，提交工作正常

我还有一个DataHomeController.php

public function newAction(Request $request){

        if(!$this->hasFuAccess() || !$this->isAdmin()){
            throw new AccessDeniedException("You do not have permission to access");
        }

        $newrecord =array();

        $dataA = new DataAPatient();
        array_push($newrecord,$dataA);
        $appendForm = $this->createNewForm($dataA);

        $appendForm->handleRequest($request);


        if($appendForm->isSubmitted()){//Save  
            if($appendForm->isValid()){    
             $tmp_pKpPatientid = $this->storeDataAPatient($dataA);
             $records = $this->getStepByStepSearch($dataA);
             return $this->render('GeneralCommonBundle:DataHome:show.html.twig', array(
                'records'=> $records,
                'isNew' => false,
                'newrecord' => $newrecord
                ));
         }
       //   }
        }

        return $this->render('DataLiveBundle:DataAPatient:new.html.twig', array(
            'form'   => $appendForm->createView(),
        ));


    }

在config.yaml中：

validation:      { enabled: true, enable_annotations: true }

和一个html.twig：

{% extends '::base.html.twig' %}

{% block body %}
{{ form_start(form, {attr: {novalidate: 'novalidate'}}) }}
{% form_theme form 'bootstrap_3_horizontal_layout.html.twig' %}

    <h1 style="margin-top:60px"><img src="{{ asset('public/images/icons/icon_data_gross.gif') }}"> Create a New Patient Dataset</h1>


          <div role="tabpanel" class="tab-pane active" id="PatientInfo">
              <div class="panel panel-default">
                  <div class="panel-body">
                     {% include 'DataLiveBundle:DataAPatient:form.html.twig' with {
                    'form':form, 'isNew': true  } only %} 
                  </div>
              </div>
          </div>

    {{ form_row(form._token) }}
    {{ form_end(form) }}



{% endblock %}

下面是methode stroeDataAPatient：

private function storeDataAPatient($dataA){

   if (!$dataA) {
        throw $this->createNotFoundException('Unable to find DataEFu2 entity.');
    }

    $em = $this->getDoctrine()->getManager();
    $session = $this->getRequest()->getSession();
    $em->persist($dataA);
    $em->flush();
    $tmp_pKpPatientid= $dataA->getpKpPatientid();

}

private function storeDataAPatient($dataA){

   if (!$dataA) {
        throw $this->createNotFoundException('Unable to find DataEFu2 entity.');
    }

    $em = $this->getDoctrine()->getManager();
    $session = $this->getRequest()->getSession();
    $em->persist($dataA);
    $em->flush();
    $tmp_pKpPatientid= $dataA->getpKpPatientid();

}

StoreDataaClient：

private function storeDataAPatient($dataA){

   if (!$dataA) {
        throw $this->createNotFoundException('Unable to find DataEFu2 entity.');
    }

    $em = $this->getDoctrine()->getManager();
    $session = $this->getRequest()->getSession();
    $em->persist($dataA);
    $em->flush();
    $tmp_pKpPatientid= $dataA->getpKpPatientid();

}

private function storeDataAPatient($dataA){

   if (!$dataA) {
        throw $this->createNotFoundException('Unable to find DataEFu2 entity.');
    }

    $em = $this->getDoctrine()->getManager();
    $session = $this->getRequest()->getSession();
    $em->persist($dataA);
    $em->flush();
    $tmp_pKpPatientid= $dataA->getpKpPatientid();

}

我可以告诉你，你可以把你的条件，如果有效和提交，为更好的表现：

 $form = $this->createForm(yourPathType, yourObject);
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            $this->getDoctrine()->getManager()->flush();
        }

---

是一个简短的代码

能否请您展示一下

DataLiveBundle:dataapient:form.html.twig

和

createNewForm

方法的代码。如果

dump（$appendForm->getData（）），将显示什么？您的
pGaWeeks
是否为空？错误（“pGaWeeks不应该是空的”）没有显示，因为我想您没有渲染它…什么是
storedataapacient
做的？“pGaWeeks”总是空的，是的。“storedataapacient”将用户输入保存在数据库中。我不完全确定，但我认为
storedataapacient（）
将刷新。你的答案是猜测。您没有解释对原始代码所做的更改，甚至没有重命名变量（
$form
->
$appendForm
），请参见更新后的问题。你的答案不能回答这个问题。
