我有一个名为survey的实体，我有一个名为Creditcards
Creditcard使用survey
manyToOne相关联
survey使用Creditcard
oneToMany相关联
该调查有大量与财务相关的问题，这些问题会保存在survey表中，它还会询问用户的信用卡相关详细信息，然后将其保存在Creditcard表中，因为用户可以拥有多个卡片，以便他们可以添加多个卡片详细信息，这是manyToOne和oneToMany发挥作用的地方。
这是我的Creditcard.orm.yml

在控制器中调用并传递给树枝的表单
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class debtType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('homeLoanMonthlyRepayments')
->add('homeLoanTotalOutstanding')
->add('carLoanMonthlyRepayments')
->add('carLoanTotalOutstanding')
->add('personalLoanMonthlyRepayments')
->add('personalLoanTotalOutstanding')
->add('otherLoanMonthlyRepayments')
->add('otherLoanTotalOutstanding')
->add('creditcards', 'collection', array('type' => new CreditcardsType(), 'allow_add' => true, 'by_reference' => false,
));
}
/**
* @param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver) {
$resolver->setDefaults(array(
'data_class' => 'ExampleBundle\Entity\survey'
));
}
/**
* @return string
*/
public function getName()
{
return 'examplebundle_debt';
}
}
最后我的debtAction处理表单并尝试保存数据
public function debtAction(Request $request){
$em = $this->getDoctrine()->getManager();
//get user id of currently logged in user
$userId = $this->getUser()->getId();
//get survey object of currently logged in user
$userExpensesInfo = $em->getRepository('ExampleBundle:survey')->findOneByuserID($userId);
$form = $this->createForm(new debtType(), $userExpensesInfo);
$form->handleRequest($request);
if($request->isMethod('POST')){
if($form->isValid()){
$userExpensesInfo->setExpenseFood($form->get('homeLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpenseFood($form->get('homeLoanTotalOutstanding')->getData());
$userExpensesInfo->setExpenseHousing($form->get('carLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpenseTransport($form->get('carLoanTotalOutstanding')->getData());
$userExpensesInfo->setExpenseFun($form->get('personalLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpenseClothing($form->get('personalLoanTotalOutstanding')->getData());
$userExpensesInfo->setExpenseUtil($form->get('otherLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpensePersonal($form->get('otherLoanTotalOutstanding')->getData());
$userExpensesInfo->getCreditcards()->add($form->get('creditcards')->getData());
$em->flush();
$this->get('session')->getFlashBag()->add(
'notice',
'Your loan information has been saved'
);
return $this->render('ExampleBundle:Default/dashboard:debt.html.twig', array(
'form'=>$form->createView(),
));
}
}
return $this->render('ExampleBundle:Default/dashboard:debt.html.twig', array(
'form'=>$form->createView(),
));
}
我已逐步完成了this文章，但我无法让保存工作，当我尝试保存时，这就是我得到的错误
A new entity was found through the relationship 'ExampleBundle\Entity\survey#creditcards' that was not configured to cascade persist operations for entity: ExampleBundle\Entity\Creditcards@000000001bbd76da000000008bbf1e28. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @ManyToOne(..,cascade={"persist"}). If you cannot find out which entity causes the problem implement 'ExampleBundle\Entity\Creditcards#__toString()' to get a clue.
500 Internal Server Error - ORMInvalidArgumentException
我在上面评论过的文章确实在this部分谈到了它，我遵循了指令，无论我做什么，我都无法通过这个错误。现在已经超过6个小时了，我正在努力解决这个问题，我不能再思考了。
如果我能在这里得到一些，我将非常感激。

答案 0 :(得分：0)
您需要将cascade: ["persist"]添加到调查名单中的oneToMany映射中。
顺便说一句：类名应该是单数和大写的。
答案 1 :(得分：0)
您想要实现的目标（在检查之后）是双向的多对多关联，如文档的第5.9章所示：http://doctrine-orm.readthedocs.org/en/latest/reference/association-mapping.html
确保正确定义您的“拥有”方面，并根据它设置并保留关联的两边（请参阅上面链接中的5.9.1） - 否则您的实体无法正确保留。
如果您只需要在提供的文档中进行单向多对多检查5.8。
答案 2 :(得分：0)
我终于开始工作了。我似乎没有正确使用Symfony保存信用卡详细信息。
在我的控制器内部，我手动设置数据，这在我的情况下完全不需要
$userExpensesInfo->setExpenseFood($form->get('homeLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpenseFood($form->get('homeLoanTotalOutstanding')->getData());
$userExpensesInfo->setExpenseHousing($form->get('carLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpenseTransport($form->get('carLoanTotalOutstanding')->getData());
$userExpensesInfo->setExpenseFun($form->get('personalLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpenseClothing($form->get('personalLoanTotalOutstanding')->getData());
$userExpensesInfo->setExpenseUtil($form->get('otherLoanMonthlyRepayments')->getData());
$userExpensesInfo->setExpensePersonal($form->get('otherLoanTotalOutstanding')->getData()); $userExpensesInfo->getCreditcards()->add($form->get('creditcards')->getData());
然后我必须将我的功能addCreditCard更改为以下
public function addCreditCard(CreditCard $card)
{
if (!$this->creditcards->contains($card)) {
$this->creditcards->add($card);
}
$card->setSurvey($this);
}
之后它完全正常工作。
