象征主义与嵌入形式集合的多对一关系

Question

我有两个实体：Doctor&时间表其中一个医生有多个时间表(OneToMany)，多个时间表有一个医生(ManyToOne)。我想从医生创建表单屏幕创建许多时间表。所以，我跟随文章嵌入表单集合一切都很好，只是我在时间表创建会话上看到医生下拉列表，这意味着我只能为现有医生创建时间表我知道医生下拉列表来自ManyToOne关系。但对于我的情况，我需要为当前医生(将在屏幕上创建的医生)创建时间表，而无需选择现有医生的下拉列表。告诉逻辑我想要什么伪代码：

//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(),
);
}

我读过所有类似的问题，但没有解决方案。请任何人帮我举一些符号初学者能理解的例子。非常感谢。

下面是表格结构&相关代码：

医生实体表

id nbsp nbsp；INT PRIMARY KEY AUTO_INCREMENT
name VARCHAR(55)不为空

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

提到嵌入式只支持基本映射

因此，带有嵌入式的ManyToOne仍然不受条令2的支持，这很遗憾。

Answer 2

即使我也不确定这种方式是否推荐。但我用以下方法解决了这个问题。首先从时间表表格类型中删除以下行：

->add('doctor')

在控制器createAction()中，在医生实体保存/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();
}
}

在控制器updateAction()中，将此代码添加到表单handleRequest之前。

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

在控制器updateAction()中，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();

在控制器updateAction()中，在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->flush()在每个循环中都需要，或者只在循环的一侧工作一次。：)
