Question

我想知道是否有人知道如何通过一个表单来编辑多个记录。此链接显示我正在寻找的确切内容：https://editor.datatables.net/examples/simple/multiRow.html。我已经创建了一个ajax调用，它将我选择的记录的id发送到我创建的editMultipleRecordsAction方法。从那里我迷失了。任何提示都会非常感激（Symfony已经有了这方面的东西吗？我应该专门为此重建一个新的FormType吗？我应该使用相同的FormType但添加Listeners吗？我应该创建一个新的实体，其中我的id属性是一个数组？ ...）。顺便说一下，我只有一个实体。

我认为实现这一目标的最简单方法是：

迭代$request->request->get('data');
从DB
为当前实体创建新表单
为每个表单手动调用Form::submit()
$form->isValid()验证（每次迭代）
$em->flush()让学说计算变更集并保存到数据库

这是一个未经测试的例子

public function editMultipleRecordsAction (Request $request)
{
    // First we select what to do based on 'action' field (add/edit/delete)
    switch ($request->request->get('action')) {
        case 'edit':

            // Fetch the payload
            $data = $request->request->get('data');

            // Fetch all edited entities
            $entities = $this->getDoctrine()->getRepository('AppBundle:Entity')
                ->findBy(['id' => array_keys($data)]);

            // Build a map of $id => $entity to use later
            $map = [];
            foreach ($entities as $entity) {
                $map[$entity->getId()] = $entity;
            }

            if (array_keys($data) !== array_keys($map)) {
                // Something went wrong, not all requested entities were fetched
            }

            // Loop over each edited entity
            foreach ($data as $id => $form_data) {
                // Create a form for the current entity (you can use createForm() as well, same thing)
                $form = $this->createFormBuilder($map[$id])
                    // Notice that the id field is not part of the form
                    ->add('name')
                    ->add('position')
                    // ->add(...)
                    ->getForm();

                // Manually submit the data for this form
                $form->submit($form_data);

                if (!$form->isValid()) {
                    // Validation error, do something...
                }
            }

            // Now we have iterated over each entity and updated it using Symfony's Form component
            // The only thing remaining is to tell Doctrine to calculate the change set and save it to the database
            $this->getDoctrine()->getManager()->flush();

            // DataTables require that you return a JSON version of updated entities
            // This will be different depending on what you use to serialize.
            // The following example applies if you are using FOS Rest Bundle:
            return $this->handleView($this->view(['data' => $entities]));
        break;

        case 'create':
            // ...
        break;

        case 'remove':
            // ...
        break;

        default:
            throw new BadRequestHttpException();
    }
}
