這裏是（EDITED ：完整的文件內容）的實體在控制器Symfony2中和學說，柱不能爲空與OneToOne關係
// Eve\MoonBundle\Entity\MoonMaterial.php
namespace Eve\MoonBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
//use Doctrine\Common\Collections\ArrayCollection;
/**
* @ORM\Table(name="_moon_material")
* @ORM\Entity()
*/
class MoonMaterial
{
public function __construct()
{
//$this->invTypes_byTypeID = new ArrayCollection();
}
// relations start
/**
* @ORM\OneToOne(targetEntity="Eve\DumpBundle\Entity\invTypes")
* @ORM\JoinColumn(name="typeID", referencedColumnName="typeID")
*/
private $invTypes_byTypeID;
public function get_invTypes_byTypeID()
{
return $this->invTypes_byTypeID;
}
// relations end

{
$this->userID = $userID;
return $this;

代碼（EDITED）
// Eve\MoonBundle\Controller\IndexController.php
namespace Eve\MoonBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Eve\MoonBundle\Entity\MoonMaterial;
class IndexController extends Controller
{
public function defaultAction($moonName)
{
// ...
$dc = $this->getDoctrine();
$form = $this
->createFormBuilder()
->add('typeID', 'choice', $choiceSettings)
->getForm();
if ($this->getRequest()->isMethod('post'))
{
$form->bind($this->getRequest());
{
$data = $form->getData();
$typeID = $data['typeID'];
if (is_int($typeID))
{
$em = $dc->getEntityManager();
$mm = $em->getRepository('EveMoonBundle:MoonMaterial');
$result = $mm->findOneBy(array(
'userID' => $this->getUser()->getID(),
'typeID' => $typeID,
'moonID' => $moon->getItemID()));
if ($result)
{
$em->remove($result);
$em->flush();
}
$moonMaterial = new MoonMaterial();
$moonMaterial
->setUserID($this->getUser()->getID())
->setTypeID($typeID)
->setMoonID($moon->getItemID());
$em->persist($moonMaterial);
$em->flush();
}
}
}
$twig = 'EveMoonBundle:Index:default.html.twig';
return $this->render($twig, array(
'formAddMoonMaterial' => $form->createView()));
}
}
時我試試這個，我得到錯誤
An exception occurred while executing 'INSERT INTO _moon_material (userID, moonID, typeID) VALUES (?, ?, ?)' with params {"1":38,"2":40001583,"3":null}:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'typeID' cannot be null
但是，當我評論OneToOne（代碼上面）關係它工作正常，所以主要麻煩是描述OneToOne關係...請幫助處理它
我想要什麼，我想重寫條目，如果存在於表「_moon_material」或簡單地寫，如果不
PS：我需要一個只爲「讀」如果你想允許空值設置
@ORM\JoinColumn(name="typeID", referencedColumnName="typeID")
到（由ID聯接名稱）
請發佈invTypes和MoonMaterial的完整類。這個錯誤顯然不在你認爲的地方 – AdrienBrault
看編輯代碼，我改了它 – user1954544
那麼你怎麼看？麻煩在哪裏？有任何想法嗎？ – user1954544
