Sonata Admin Bundle 一对多关系不保存外国 ID [英] Sonata Admin Bundle One-to-Many relationship not saving foreign ID

问题描述

我在将 SonataAdminBunle 与 symfony 2.2 结合使用时遇到了问题.我有一个 Project 实体和一个 ProjectImage 实体，并指定了这两者之间的一对多关系，如下所示:

I have a problem with the SonataAdminBunle in combination with symfony 2.2. I have a Project entity and a ProjectImage entity and specified a One-to-Many relationship between these two like so:

class Project
{
    /**
     * @ORM\OneToMany(targetEntity="ProjectImage", mappedBy="project", cascade={"all"}, orphanRemoval=true)
     */
    private $images;
}

class ProjectImage
{

    /**
     * @ORM\ManyToOne(targetEntity="Project", inversedBy="images")
     * @ORM\JoinColumn(name="project_id", referencedColumnName="id")
     */
    private $project;
}

我已经配置了 ProjectAdmin 和 ProjectImageAdmin:

I've configured the ProjectAdmin and ProjectImageAdmin:

class ProjectAdmin extends Admin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('title')
            ->add('website')
            ->add('description', 'textarea')
            ->add('year')
            ->add('tags')
            ->add('images', 'sonata_type_collection', array(
                            'by_reference' => false
            ), array(
                            'edit' => 'inline',
                            'inline' => 'table',
                            'sortable' => 'id',
            ))
            ;
    }
}

class ProjectImageAdmin extends Admin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('file', 'file', array(
                          'required' => false
            ))
            ;
    }
}

问题是在数据库的project_image表中，project_id没有保存，其他数据都保存了，图片也保存了.在其他任何地方都找不到有效的答案.

The problem is that in the project_image table in the database the project_id is not saved, while all other data is and also the image is saved. Couldn't find a working answer anywhere else.

推荐答案

虽然无关，但我会稍微调整您的一对多注释:

Although unrelated, I'd slighty tweak your One-to-Many annotation:

class Project
{
    /**
     * @ORM\OneToMany(targetEntity="ProjectImage", mappedBy="project", cascade={"persist"}, orphanRemoval=true)
     * @ORM\OrderBy({"id" = "ASC"})
     */
    private $images;
}

回到正轨，您的注释和奏鸣曲管理表单看起来不错，所以我很确定您在 Project 实体类中缺少其中一种方法:

Back on track, your annotations and Sonata Admin forms look fine, so I'm pretty sure you're missing one of those methods in your Project entity class:

public function __construct() {
    $this->images = new \Doctrine\Common\Collections\ArrayCollection();
}

public function setImages($images)
{
    if (count($images) > 0) {
        foreach ($images as $i) {
            $this->addImage($i);
        }
    }

    return $this;
}

public function addImage(\Acme\YourBundle\Entity\ProjectImage $image)
{
    $image->setProject($this);

    $this->images->add($image);
}

public function removeImage(\Acme\YourBundle\Entity\ProjectImage $image)
{
    $this->images->removeElement($image);
}

public function getImages()
{
    return $this->Images;
}

在您的管理员课程中:

public function prePersist($project)
{
    $this->preUpdate($project);
}

public function preUpdate($project)
{
    $project->setImages($project->getImages());
}
