编辑多体关联理论2和zf2

Question

我有一个这样的场景：Hmo与Hcp具有双向的Many2Many关联。 我的意思是Hmo可以添加Hcp，Hcp应该能够查看其Hmos并查看有关Hmo的其他信息。

我已经创建了几个Hmos和Hcps，所以实际的关联是在编辑Hmos时，为了选择Hcps进行关联，我一直遇到错误：

传递给Hmo \\ Entity \\ Hmos :: addHcp（）的参数1必须是Hcp \\ Entity \\ Hcps的实例，给定的Doctrine \\ Common \\ Collections \\ ArrayCollection的实例，在/ var / www / insta / vendor / doctrine / doctrine中调用第61行的-module / src / DoctrineModule / Stdlib / Hydrator / Strategy / AllowRemoveByValue.php，并在第58行的/var/www/insta/module/Hmo/src/Hmo/Entity/Hmos.php中定义

我以为print_r（$ entity-> getHcp（））应该返回选定的Hcp对象？ 我已经将addHcp（）的参数切换为arraycollection和Hcps，但仍然拍摄相同的错误。 这个代码请问有什么问题吗？

Answer 1

您应该将ArrayCollection传递给添加方法-我认为这是问题所在。 修改您的添加方法，如下所示：

public function addHcp(Collection $hcps)
{
    foreach($hcps as $hcp) {
        if( ! $this->hcp->contains($hcp)) {
            $this->hcp->add($hcp);
            $hcp->addHmo(new ArrayCollection(array($this));
        }
    }
}

还有你的删除方法（同样的方式）：

public function removeHcp(Collection $hcps) 
{
    foreach($hcps as $hcp) {
        $this->hcp->removeElement($hcp);
        $hcp->removeHmo(new ArrayCollection(array(this)));
    }
}

Doctrine还将Collections传递给添加/删除方法，这就是为什么它不起作用的原因

Answer 2

我认为问题出在您的实体方法上。

我建议您阅读Doctrine ObjectHydrator上的文档 ，然后您很可能会发现出了什么问题。 快速浏览一下，我会说错误出在setHcp和setHmo方法中。 由于您具有ManyToMany关联，因此根本不应该在关联中使用set方法。 在文档本章的此处检查setTags的注释。 您实际上应该只使用addHcps ， addHcp ， removeHcp和removeHcps方法。

集合绝对不能交换。
