我想插入EdiTradingPartnerTransactions表但我真的不知道该怎么办，因为我收到了这个错误：

可捕获的致命错误：参数1传递给矩阵\ MatrixEdiBundle \实体\ EdiTradingPartnerTransactions :: setEdiTp（）必须是一个实例 Matrix \ MatrixEdiBundle \ Entity \ EdiTradingPartner，给定的字符串，调用在 C：\ XAMPP \ htdocs中\ Editracker \ SRC \矩阵\ MatrixEdiBundle \控制器\ MatrixController.php 在第474行并在中定义 C：\ XAMPP \ htdocs中\ Editracker的\ src \矩阵\ MatrixEdiBundle \实体\ EdiTradingPartnerTransactions.php 第85行

这是我在控制器方面的功能：

public function deleteTpTransAction($tpId, $docType, $direction, $tpName) {
    $em = $this->getDoctrine()->getManager();
    $docTypeId = $em->getRepository('MatrixEdiBundle:EdiDocType')->getId($docType, $direction);

    if ($docTypeId != null) {
        $result = $em->getRepository('MatrixEdiBundle:EdiTradingPartnerTransactions')->getTpTrans($tpId, $docType, $direction);
        if ($result == null) {
            $transaction = new EdiTradingPartnerTransactions();
            $transaction->setEdiTp($tpId);
            $transaction->setEdiDocType($docTypeId);

            $em->persist($transaction);
        } else {
            foreach ($result as $key) {
                $id = $key->getEdiTpTransactionsId();
                $transaction = $em->getRepository('MatrixEdiBundle:EdiTradingPartnerTransactions')->find($id);

                $em->remove($transaction);
            }                
        }
        $em->flush();
    }
    return $this->redirect($this->generateUrl('matrix_edi_tpTrans'));
}

真的很感激任何帮助。先谢谢！

Answer 1

这里的错误非常明确：至少对于关系，Doctrine句柄只处理＆＃34;相关的对象＆＃34; （让我们这样称呼）实体。

当你这样做时

$transaction->setEdiTp($tpId);
$transaction->setEdiDocType($docTypeId);

您正在尝试插入相关对象的ID。这是一个错误：虽然你的db需要一个整数（外键），但是Doctrine是一个抽象的＆＃34;枕头＆＃34;你的代码和数据库之间;它选择使用对象而不是id（你可以很清楚地看到实体类文件）

此处的解决方案非常简单：

从db获取setEdiTp和setEdiDocType
将它们传递给函数

在PHP（Symfony）中：

$ediTp = $em
    ->getRepository('MatrixEdiBundle:EdiTp')
    ->findOneById($tpId);

$ediDocType = $em
    ->getRepository('MatrixEdiBundle:EdiDocType')
    ->findOneById($docTypeId);

然后

$transaction->setEdiTp($ediTp);
$transaction->setEdiDocType($ediDocType);

Answer 2

您的错误是因为setEdiTp需要EdiTradingPartner的实例。

您的错误说string given。

因为$tpId是字符串。

验证

更改

$transaction->setEdiTp($tpId);

要

// $transaction->setEdiTp($tpId); var_dump($tpId);

通常，$ tpId返回一个字符串，而不是一个对象。

因此，当您致电deleteTpTransAction时，$tpId必须是setEdiTp的实例

变更：

$editp = $em->getRepository('MatrixEdiBundle:EdiTradingPartner')->find($tpId);

并更改

$transaction->setEdiTp($tpId);

按

$transaction->setEdiTp($editTp);

Symfony插入外键值
