问题描述
这是一个实体(已完整文件内容)
// EveMoonBundleEntityMoonMaterial.php
namespace EveMoonBundleEntity;
use DoctrineORMMapping as ORM;
//use DoctrineCommonCollectionsArrayCollection;
/**
* @ORMTable(name="_moon_material")

class MoonMaterial
{
public function __construct()
{
//$this->invTypes_byTypeID = new ArrayCollection();
}
// relations start
/**
* @ORMOneToOne(targetEntity="EveDumpBundleEntityinvTypes")

*/
private $invTypes_byTypeID;
public function get_invTypes_byTypeID()
{
return $this->invTypes_byTypeID;
}
// relations end
/**

public function setUserID($userID)
{
$this->userID = $userID;
return $this;
}
/**

public function getUserID()
{
return $this->userID;
}
/**

*/
public function setMoonID($moonID)
{
$this->moonID = $moonID;
return $this;
}
/**

public function getMoonID()
{
return $this->moonID;
}
/**

*/
public function setTypeID($typeID)
{
$this->typeID = $typeID;
return $this;
}
/**

public function getTypeID()
{
return $this->typeID;
}
}
控制器中的代码(已编辑)
// EveMoonBundleControllerIndexController.php
namespace EveMoonBundleController;
use SymfonyBundleFrameworkBundleControllerController;
use EveMoonBundleEntityMoonMaterial;
class IndexController extends Controller
{
public function defaultAction($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()));
}
}
当我尝试这个时,我得到了错误
when i try this, i get error
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
但是当我评论 OneToOne(上面的代码)关系时它可以正常工作,所以主要问题在于描述 OneToOne 关系......请帮助处理它
but when i comment the OneToOne (code above) relationship it work correctly, so main trouble is in description OneToOne relationship... pls help to deal with it
我想要什么,如果表_moon_material"中存在,我想重写条目,如果不存在则直接写
what i want, i want rewrite entry if exist in table "_moon_material" or simply write it if not
ps:我只需要读取"的关系(通过 id 连接名称)
ps: i need that relation only for "read" (join name by id)
推荐答案
我不知道为什么,我不能做单向关系,所以我通过在invTypes表注释中添加一些代码来双向解决它
i don't know why, i can't do unidirectional relations, so i solved it by bidirectional by adding some code to invTypes table annotation
这篇关于Symfony2 和 Doctrine,具有 OneToOne 关系的列不能为空的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
