通过这种关系发现了一个新的实体。教义 [英] A new entity was found through the relationship. Doctrine

问题描述

Doctrine\ORM\ORMInvalidArgumentException

Doctrine\ORM\ORMInvalidArgumentException

通过关系Core\Model\Filter＃category找不到新实体，该关系未配置为级联实体的持久性操作：Core\Model\Category @ 00000000314fc99200005639c0395a5e。要解决这个问题：在这个未知实体上显式调用EntityManager＃persist（）或配置级联在映射中保留这个关联，例如@ManyToOne（..，cascade = {persist}）。如果您找不到哪个实体导致问题实现'Core\Model\Category #__ toString（）'来获取线索。

A new entity was found through the relationship 'Core\Model\Filter#category' that was not configured to cascade persist operations for entity: Core\Model\Category@00000000314fc99200005639c0395a5e. 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 'Core\Model\Category#__toString()' to get a clue.

此函数导致异常。
代码中的一些comits。
它是ZendFramework 2。

This function cause an exception. Some comits in code. It is ZendFramework 2.

protected function handleCategory( $data, \Core\Model\Project $project )
{
    $filter = $this->sl()->get( "Core\Filter\JSON\Category" );
    $filter->setData( $data );
    if( !$filter->isValid() ){
        $id = @$data[ 'id' ];
        $report = array(
            'id' => $id,
            'messages' => $filter->getMessages()
        );
        return $report;
    }

    $filteredData = $filter->getValues(); 
    $repo = $this->em()->getRepository( "Core\Model\Category" );
    $category = $repo->findOneBy(
        array(
            'id' => $filteredData[ 'id' ],
            'project' => $project->getId()
        )
    );

    $b = false;
    if( !$category ){
        $b = true;
        $category = new \Core\Model\Category;
        $category->setProject( $project )
                ->setCreatedAt( new \DateTime() );
    }
    $category->setUpdatedAt( new \DateTime() );

    /* Hydrate Category  */
    $hydrator = $this->sl()->get( "Core\Hydrator\JSON\Category" );
    $hydrator->hydrate( $filteredData, $category );

    /* Persist Category */
    $this->em()->persist($category);

    if($b)
    {
        /* Return Filter Data */
        $filterData = $hydrator->get();

        /* Hydrate Filter */
        $filterHydrator = $this->sl()->get( 'Core\Hydrator\JSON\Filter' );
        //$filtersObj = array();
        foreach($filterData as $i => $fdata)
        {
            $filterObj = new \Core\Model\Filter;
            $filterObj->setProject($project)->setCategory($category);
            $filterHydrator->hydrate($fdata, $filterObj);
            $this->em()->persist($filterObj);

            /*Breaks after any flush after second persist*/
            $this->em()->flush();
        }
    }

    return true;
}

我试图通过以下方式解决这个问题：

I tried to solve this problem by:

• MERGE，但另有例外，A managed dirty + entity [...]


• cascade = {persist}，但是没有什么发生。


• 重写代码，你看到的是，我一个个坚持一个功能一个EntityManager（如果我错过了一些请告诉我）

从来没有使用ZendFramework工作。我喜欢Symfony与应用程序/控制台管理器，所有实体与表创建自动。

Never work before with ZendFramework. I love Symfony with app/console manager, all entities with tables creates authomatically.

推荐答案

解决这个问题添加

$this->em()->clear('Filter');

after

$this->em()->persist($filterObj);

我们可以删除

$this->em()->flush();

更快地做脚本。我把它粘贴到最后。

To do script faster. I paste it in the end.

我认为这不是一个好主意，但它的作品。
我还在等你的答案。

I think this is not good idea, but it works. I still waiting for your answers.
