Question

我的应用程序中有Post和Category实体。他们有一个ManyToMany关系。另外，我使用FosRestBundle处理请求。问题是，当我创建具有给定类别的帖子时，他们不与之关联。而是创建新类别并将其与帖子关联。我想将这些类别ID分配给发布，而不是忽略。这是我发送到服务器的json。

{
   "title":"Post title #1",
   "content":"Post content #1",
   "excerpt":null,
   "alias":"post-title-1",
   "image":null,
   "status":"draft",
   "categories":[
      {
         "id":301,
         "title":"Category title #0",
         "content":"Post content #0",
         "status":"published",
         "alias":"category-title-0",
         "image":null,
         "created_at":"2018-06-25T16:15:30+00:00",
         "updated_at":"2018-06-25T16:15:30+00:00"
      },
      {
         "id":302,
         "title":"Category title #1",
         "content":"Post content #1",
         "status":"published",
         "alias":"category-title-1",
         "image":null,
         "created_at":"2018-06-25T16:15:30+00:00",
         "updated_at":"2018-06-25T16:15:30+00:00"
      }
   ]
}

PostController.php

public function update(Post $post, Request $request)
{
    // Set post type to default TYPE_POST
    $post->setType(Post::TYPE_POST);
    $form = $this->createForm(PostType::class, $post);
    // Fill the form with submitted data
    $form->submit($request->request->all());
    // Validate form
    if ($form->isValid()) {


        // Convert alias if needed
        $post->setAliasBasedOnTitle();
        // Save to database if valid
        $this->getDoctrine()->getManager()->flush();
        // Transform post data
        $manager = new Manager();
        $manager->parseIncludes('categories');
        $manager->setSerializer(new DataSerializer());
        // Prepare data for response
        $resource = new Item($post, new PostTransformer($this->container));
        // Status code 201 Created
        return $this->json($manager->createData($resource)->toArray(), 200);
    }
    // Return form errors
    return $this->json(array(
        'messages' => $this->getFormErrors($form)
    ), 400);
}

PostType.php

class PostType extends AbstractType
{
    protected $transformer;

    public function __construct(JsonToCategoryTransformer $transformer)
    {
        $this->transformer = $transformer;
    }
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title')

            ->add('excerpt')
            ->add('alias')
            ->add('image', EntityType::class, array(
                'class' => Image::class
            ))
            ->add('categories', CollectionType::class, array(
                'entry_type' => CategoryType::class,
                'allow_add' => true,
                'by_reference' => false,
            ))
            ->add('status');
    }


    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Post::class,
            'csrf_protection' => false,
            'cascade_validation' => true,
