我想弄清楚我做错了什么。我收到400个错误的请求,试图通过角度服务发送发布请求。我有2个实体 - Document和DocumentCategory(多对多关系)。我可以发布文档本身(没有类别),没有问题。400错误请求Symfony 3与角度

文档create.component.ts

createDocument(title, body, categories) { 
    let document = {title: title, body: body, categories: categories}; 
    this._crudService.createDocument(document).subscribe(
     data => { 
      return true; 
     }, 
     error => { 
      console.error("Error saving document! " + error); 
      return Observable.throw(error); 
     } 
    ); 
} 

crudService.ts

createDocument(document) { 
    let headers = new Headers({'Content-Type': 'application/json'}); 
    let options = new RequestOptions({headers: headers}); 
    //let body = JSON.stringify(document); 
    let body = document; 
    return this.http.post 
     ('http://localhost:8000/documents', body, headers); 
} 

形式

public function buildForm(FormBuilderInterface $builder, array $options) { 
    $builder 
      ->add('title', TextType::class) 
      ->add('body', TextType::class) 
      //->add('categories', TextType::class) 
      ->add('categories', EntityType::class, array(
       'class' => 'AppBundle:DocumentCategory', 
       'multiple' => true, 
       'expanded' => true, 
       'by_reference' => false, 
       'choice_label' => 'id', 
      )) 
    ; 
} 

Document.php

/** 
* @ORM\ManyToMany(targetEntity="DocumentCategory", mappedBy="documents") 
* @JMSSerializer\Expose 
*/ 
private $categories; 

DocumentCategory.php

/** 
* @ORM\ManyToMany(targetEntity="Document", inversedBy="categories") 
* @ORM\JoinTable(name="document_category_document") 
* @JMSSerializer\Expose 
*/ 
private $documents;

    ] 
} 

正如我所说的,如果我删除类别,一切正常。我无法弄清楚:(

编辑:邮差这显示在回应时,我尝试发送上述JSON作为应用/ JSON:

{ 
    "children": { 
    "title": {}, 
    "body": {}, 
    "categories": { 
     "errors": [ 
     "This value is not valid." 
     ], 
     "children": { 
     "1": {}, 
     "2": {}, 
     "3": {}, 
     "4": {} 
     } 
    } 
    } 
}

请使用类似邮递员的方式将数据发送到后端。这将指定它是否和角度问题或后端。我假设它的后端相关。 – hogan

请参阅编辑 - 为什么类别无效? – Tompo

它必须是后端--JSON是有效的,我可以发布文档和类别,但不参考。 – Tompo

后looong时候,我终于做到了这是我的结果万一有人有simmilar问题这不是最优雅的解决方案,我将尝试找到一个更好的,但至少它的作品的问题是在控制器现在POST方法看起来是这样的:。

public function postAction(Request $request) { 
    $form = $this->createForm(DocumentType::class, null, [ 
     'csrf_protection' => false, 
    ]); 
    $form->submit($request->request->all()); 
    if (!$form->isValid()) { 
     return $form; 
    } 

    $em = $this->getDoctrine()->getManager(); 
    $document = $form->getData(); 
    $categories = $request->request->get('categories'); 

    foreach ($categories as $categoryId) { 
     $category = $em->getRepository('AppBundle:DocumentCategory')->find((int)$categoryId['id']); 
     $category->addDocument($document); 
     $document->addCategory($category); 
     $em->persist($category);    
    } 

    $em->persist($document); 
    $em->flush(); 

    $routeOptions = [ 
     'id' => $document->getId(), 
     '_format' => $request->get('_format'), 
    ]; 

    return $this->routeRedirectView('get_document', $routeOptions, Response::HTTP_CREATED); 
} 

而我的表格很简单:

public function buildForm(FormBuilderInterface $builder, array $options) { 
    $builder 
      ->add('title', TextType::class) 
      ->add('body', TextType::class) 
    ;   
}
