我是Symfony2和Doctrine的新手，我有点卡住了。保存到数据库时收到错误。
An exception occurred while executing 'INSERT INTO tho_provider (provid_name, provid_logo, provid_logo_path, created_time, provider_created_by) VALUES (?, ?, ?, ?, ?)' with params ["test", {}, "qwwwww", "2015-08-11 16:03:15", null]:
SQLSTATE [23000]：完整性约束违规：1048列'provider_created_by'不能为空
我有一个表单，其中我只获取提供者名称输入和徽标，其余是我在控制器中处理，包括provider_created_by，它在刷新后立即获取null，在flush命令显示值之前。
public function createAction(Request $request)
{
$user = $this->getUser();
$entity = new Provider();
$entity->setProvidLogoPath("qwwwww");
$entity->setProviderCreatedBy($user);
$form = $this->createCreateForm($entity);
$form->handleRequest($request);
if ($form->isValid()) {
//$entity->setCreatedBy($user);
$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('provider_show', array('id' => $entity->getId())));
}
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}
我有实体，PROVIDER和USER。 用户可以创建许多提供者，提供者只属于一个用户。一对多关系。

答案 0 :(得分：2)
您的元数据
/**
* @var integer
*
* @ORM\Column(name="provider_created_by", type="integer")
*/
public $providerCreatedBy;
但是你传递的是一个对象（可能是null）：
$user = $this->getUser();
/* ... */
$entity->setProviderCreatedBy($user);
并且setter没有类型提示：
public function setProviderCreatedBy($providerCreatedBy)
{
$this->providerCreatedBy = $providerCreatedBy;
return $this;
}
您必须使用$providerCreatedBy实体更改ManyToOne到User的映射。
答案 1 :(得分：1)
检查您的用户是否已登录，$this->getUser()如果用户是匿名的，则返回null，我认为您应该从列类型{{更改providerCreatedBy字段的映射信息1}} integer与ManyToOne类的关系..
