Question

我有2个实体：医生＆amp; 时间表其中一位医生有很多时间表（OneToMany），许多时间表都有一位医生（ManyToOne）。我想从Doctor Create form Screen创建许多时间表。所以，我按照文章embedded form collection 一切都工作得很好，除了我正在让医生下载时间表创建会话，这意味着我只能为现有医生创建时间表。我知道医生下拉来自ManyToOne关系。但就我而言，我需要为当前的医生（即将在屏幕上创建的医生）制定时间表，而不选择现有医生的下拉菜单。用伪代码告诉逻辑我想要什么：

//Doctor Create Action 
        public function createAction(Request $request)
    {
        $entity = new Doctor();
        $form = $this->createCreateForm($entity);
        $form->handleRequest($request);

    if ($form->isValid()) {

      // Save(Persist) Doctor   
      // Grab Newly Created Doctor ID
      // Create Timetables  with that Doctor ID
      // done   
    }

    return array(
        'entity' => $entity,
        'form'   => $form->createView(),
    );
}

我已经阅读了所有类似的问题但没有解决方案。请大家帮我一些symfony初学者可以理解的例子。谢谢。

下面是表格结构＆amp;相关代码：

医生实体表

id INT PRIMARY KEY AUTO_INCREMENT
name VARCHAR（55）NOT NULL

时间表实体表
  id INT PRIMARY KEY AUTO_INCREMENT
  doctor_id INT （医生的外键）
  clinic_id INT （诊所的外键）
  _time VARCHAR（255）NOT NULL

提到嵌入式广告只支持基本映射

因此，带有Embedded的ManyToOne仍未得到Doctrine 2的支持，很遗憾。

即使我不确定这种推荐方式。但我已经按照以下方式解决了它。首先从时间表表单类型中删除以下行：

->add('doctor')

在您的控制器中，createAction（）会在您的医生实体保存/刷新后添加此代码。

$doctor = $form->getData();
if($doctor->getTimetables())
{
     foreach ($doctor->getTimetables() as $timetable) {
           $timetable->setDoctor($doctor);
           $em->persist($timetable);
           $em->flush();
     }
}

在您的控制器updateAction（）中，为表单handleRequest添加此代码。

$entity = $em->getRepository('YourBundle:Doctor')->find($id);
$originalTimetables = new ArrayCollection();
if($entity->getTimetables())
{
     foreach ($entity->getTimetables() as $timetable) {
          $originalTimetables->add($timetable);
     }
}

在您的控制器中，updateAction（）在表单handleRequest之后和医生实体刷新之前添加此代码。

$editForm->handleRequest($request);
if ($editForm->isValid()) {
   foreach ($originalTimetables as $timetable) 
   {
       if (false == $entity->getTimetables()->contains($timetable)) 
       {     
           $timetable->getDoctor()->removeTimetable($timetable);
           $em->remove($timetable);
           $em->flush();
       }
   }
   $em->flush();

在您的控制器中updateAction（）在您的医生实体刷新后添加此代码。

   $doctor = $editForm->getData();
   if($doctor->getTimetables())
   {
        foreach ($doctor->getTimetables() as $timetable) 
        {
           $timetable->setDoctor($doctor);
           $em->flush();
        }
   }
}

我不确定，甚至没有尝试过$ em-＆gt; flush（）将在每个循环中使用，或者只有在它工作时才能解决循环的一面。：）
