我正在尝试将数据插入到db中，但它显示了一些错误，例如

我的模型实体

        $product->setSalesperson('Ergonomic and stylish!');
        $product->setQualification('1111');
        //var_dump($r);die();
        $em = $this->getEntityManager(); 
        $em->persist($product);
        $em->flush();*/
       $product= $this->create('Keyboard','000000001ae10dda000000003c4667a6','Ergonomic and stylish!','1111');

我正在使用Mouf框架。我遇到了这个问题。有人请帮我解决这个问题。提前致谢

Answer 1

正如@rokas所建议的那样，你应该开始阅读更多关于Doctrine的内容。这不是Mouf问题，这显然是一个Doctrine ORM问题，所以适当的文档在这里：http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/index.html

以下是一些提示：

您的控制器调用setdata方法

$user_data=$this->requestDao->setdata();

setdata方法调用：

$product= $this->create('Keyboard','000000001ae10dda000000003c4667a6','Ergonomic and stylish!','1111');

现在，create方法是：

public function create(...$params) : Request
{
    $entity = new Request(...$params);
    $this->getEntityManager()->persist($entity);
    return $entity;
}

这意味着它将使用以下参数调用Request构造函数：

$entity = new Request('Keyboard','000000001ae10dda000000003c4667a6','Ergonomic and stylish!','1111');

查看Request构造函数：

public function __construct($salesperson, $client, $status, $qualification) {
    $this->salesperson = $salesperson;
    $this->client = $client;
    $this->status = $status;
    $this->qualification = $qualification;
}

如您所见，第一个参数是$salesperson。你试着把价值＆＃34;键盘＆＃34;这里。 $salesperson属性以这种方式定义：

/**
 * @ORM\ManyToMany(targetEntity="Salesperson", inversedBy="request")
 * @ORM\JoinTable(name="request_salesperson")
 * @var Salesperson
 */
private $salesperson;

/**
 * @param Salesperson $salesperson
 */
public function setSalesperson($salesperson)
{
    $this->salesperson = $salesperson;
}

现在，我认为这是你的问题。

$salesperson属性被定义为＆＃34; ManyToMany＆＃34;协会。所以你真的不能在这里放一个字符串，它是Salesperson的集合。顺便说一句，你不应该设置＆＃34;什么都有。应完全移除二传手。

相反，您应该考虑按照此处的文档使用它：http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/working-with-associations.html

例如：

$request->getSalesPersons()->add($someObjectRepresentingAPerson);

另请注意，由于$salesperson代表Salesperson对象的集合，因此您应该将其命名为$salesPersons（复数形式）

使用doctrine ORM插入db时出错
