完整性約束違規：1048'announcement_id'列不能爲空

Question

我有兩個模型：Entity \ Announcement.php和Entity \ Submission.php。

在我的實體\ Submission.php，我這樣定義與實體\ Announcement.php的關係：

/** 
* @ORM\ManyToOne(targetEntity="AppBundle\Entity\Announcement") 
* @ORM\JoinColumn(nullable=false) 
*/ 
protected $announcement; 

當用戶訪問一個通知他們必須提交建議書的能力。

在我的控制，我這樣定義的提交動作：

/** 
* @Route("/submit/{id}", name="submissions_new") 
*/ 
public function submitAction(Request $request, Announcement $id) 
{ 
    $submission = new Submission(); 
    $submission->setAnnouncement($id); 

    $form = $this->createForm(SubmissionType::class); 

    $form->handleRequest($request); 

    if ($form->isSubmitted() && $form->isValid()) { 

     $em = $this->getDoctrine()->getManager(); 

     $submission = $form->getData(); 

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

     return $this->redirectToRoute('announcements_list'); 
    } 

    return $this->render(':submissions:submit.html.twig', [ 
     'form' => $form->createView(), 
     'announcement' => $id->getId() 
    ]); 
} 

當我試圖從我的路線提交/提交/ 73c67a07-744d-11e7-9670-08d40c1d4f7f，我得到這個錯誤：

An exception occurred while executing 'INSERT INTO reports (id, title, date, author, description, announcement_id) VALUES (?, ?, ?, ?, ?, ?)' with params ["ff28c231-7843-11e7-a72b-08d40c1d4f7f", "aaa", "2012-01-01 00:00:00", "aaa", "aaa", null]: 

Integrity constraint violation: 1048 Column 'announcement_id' cannot be null 

當我評論這條線在我的控制器：

//$submission = $form->getData(); 

，並嘗試再次提交，我得到這個錯誤：

An exception occurred while executing 'INSERT INTO reports (id, title, date, author, description, announcement_id) VALUES (?, ?, ?, ?, ?, ?)' with params ["d12ea15b-7843-11e7-a72b-08d40c1d4f7f", null, null, null, null, "73c67a07-744d-11e7-9670-08d40c1d4f7f"]: 

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'title' cannot be null 

你能否幫忙提交所有的字段？

謝謝

public function submitAction(Request $request, Announcement $id) 
{ 
    $form = $this->createForm(SubmissionType::class); 

    $form->handleRequest($request); 

    if ($form->isSubmitted() && $form->isValid()) { 

     $em = $this->getDoctrine()->getManager(); 

     $formData = $form->getData(); 

     $submission = new Submission(); 
     $submission->setAnnouncement($id); 
     //to fill the $submission with data from forms 
     //$submission->setTitle($formData['title']); 
     //........... 

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

     return $this->redirectToRoute('announcements_list'); 
    } 

    return $this->render(':submissions:submit.html.twig', [ 
     'form' => $form->createView(), 
     'announcement' => $id->getId() 
    ]); 
}

在你的$ id真的是你的數據庫中的對象？

/** 
* @Route("/submit/{id}", name="submissions_new") 
*/ 

public function submitAction(Request $request, int $id) 
{ 
    $em = $this->getDoctrine()->getManager(); 

    $submission = new Submission(); 

    $announcement = $em->getRepository(Announcement::class)->find($id); 

    if (!$announcement) { 
     return $this->redirectToRoute('announcements_list'); 
    } 

    $submission->setAnnouncement($announcement); 

    $form = $this->createForm(SubmissionType::class, $submission); 

    $form->handleRequest($request); 

    if ($form->isSubmitted() && $form->isValid()) { 

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

     return $this->redirectToRoute('announcements_list'); 
    } 

    return $this->render(':submissions:submit.html.twig', [ 
     'form' => $form->createView(), 
     'announcement' => $announcement->getId() 
    ]); 
}
