添加属性到/扩展 Sonata Media 实体答案

【问题描述】：

我想向 Sonata Media 实体添加属性，但我无法让它工作。我正在使用 Sonata Media Bundle 2.3，并已按照手册进行安装。我还使用 Sonata Easy Extends Bundle 对其进行了扩展。

当我向Application\Sonata\MediaBundle\Entity\Media 添加一个属性时，当我运行doctrine:generate:diff 时它不会被拾取（'未在您的映射信息中检测到更改。'）。

覆盖config.yml 中的媒体类也不会产生影响。

这是Application\Sonata\MediaBundle\Entity\Media.php中的代码：

<?php

namespace Application\Sonata\MediaBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Sonata\MediaBundle\Entity\BaseMedia as BaseMedia;

/**
 * @ORM\Entity
 */
class Media extends BaseMedia
{
    /**
     * @var integer $id
     */
    protected $id;

    /**
     * @ORM\Column(type="string", nullable=true)
     */
    protected $test;

    /**
     * @return mixed
     */
    public function getTest()
    {
        return $this->test;
    }

    /**
     * @param mixed $test
     */
    public function setTest($test)
    {
        $this->test = $test;
    }

    /**
     * Get id
     *
     * @return integer $id
     */
    public function getId()
    {
        return $this->id;
    }
}

在config.yml:

sonata_media:
    class:
        media: Application\Sonata\MediaBundle\Entity\Media
        gallery: Application\Sonata\MediaBundle\Entity\Gallery
        gallery_has_media: Application\Sonata\MediaBundle\Entity\GalleryHasMedia

同样，如果我将该部分注释掉，我会得到相同的结果。

更新：当我创建添加属性的自定义迁移时，当我扩展 MediaAdmin 时，当我转到图像编辑页面时，test 字段不会显示：

// Application\Sonata\MediaBundle\Admin\MediaAdmin.php
<?php
namespace Sonata\MediaBundle\Admin;

use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Show\ShowMapper;

class MediaAdmin extends Admin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('name', null, ['required' => false])
            ->add('enabled', null, ['required' => false])
            ->add('authorName', null, ['required' => false])
            ->add('cdnIsFlushable', null, ['required' => false])
            ->add('description', null, ['required' => false])
            ->add('copyright', null, ['required' => false])
            ->add('test', null, ['required' => false])
            ->add('binaryContent', 'file', ['required' => false]);
    }
}

因此，Sonata 似乎忽略了扩展的媒体包（事实并非如此，因为当我删除 Application\Sonata\MediaBundle\Entity\Media.php 时，我收到一个错误）。

【解决方案1】：

我需要为图像创建不同的属性，这是我使用默认原则和提供程序的解决方案。我用的是easy-extends。

要在 Media 上添加不带注释的属性，您可以使用节点 <field name="url" type="string"/> 来获得类似 media.phpcr.xml 的内容：

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xsi="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
    <!--
         This file has been generated by the EasyExtends bundle ( https://sonata-project.org/easy-extends )

         References :
            xsd                  : https://github.com/doctrine/doctrine2/blob/master/doctrine-mapping.xsd
            xml mapping          : http://www.doctrine-project.org/projects/orm/2.0/docs/reference/xml-mapping/en
            association mapping  : http://www.doctrine-project.org/projects/orm/2.0/docs/reference/association-mapping/en
    -->
    <entity
        name="Application\Sonata\MediaBundle\Entity\Media"
        table="media__media"
        >

        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>
        <field name="url" type="string"/>

    </entity>
</doctrine-mapping>

然后，在不使用注释的情况下，您需要添加您的扩展 Media.php ：

<?php

namespace Application\Sonata\MediaBundle\Entity;

use Sonata\MediaBundle\Entity\BaseMedia as BaseMedia;

/**
 * This file has been generated by the Sonata EasyExtends bundle.
 *
 * @link https://sonata-project.org/bundles/easy-extends
 *
 * References :
 *   working with object : http://www.doctrine-project.org/projects/orm/2.0/docs/reference/working-with-objects/en
 *
 * @author Christophe Ferreboeuf <christophe@codivores.com>
 */
class Media extends BaseMedia
{
    /**
     * @var int $id
     */
    protected $id;

    /**
     * Permits to link the image to a different location on the website
     * @var string 
     */
    protected $url;

    /**
     * Get id
     *
     * @return int $id
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * 
     * @return string
     */
    public function getUrl() {
        return $this->url;
    }

    /**
     * 
     * @param string $url
     * @return \Application\Sonata\MediaBundle\Entity\Media
     */
    public function setUrl($url) {
        $this->url = $url;
        return $this;
    }


}

并为 ORM media.orm.xml 声明它：

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xsi="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
    <!--
         This file has been generated by the EasyExtends bundle ( https://sonata-project.org/easy-extends )

         References :
            xsd                  : https://github.com/doctrine/doctrine2/blob/master/doctrine-mapping.xsd
            xml mapping          : http://www.doctrine-project.org/projects/orm/2.0/docs/reference/xml-mapping/en
            association mapping  : http://www.doctrine-project.org/projects/orm/2.0/docs/reference/association-mapping/en
    -->
    <entity
        name="Application\Sonata\MediaBundle\Entity\Media"
        table="media__media"
        >

        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>
        <field name="url" column="url" type="string" nullable="true" length="255"/>

    </entity>
</doctrine-mapping>

要绕过管理员的问题，您需要覆盖图像的提供者：

<?php
namespace Application\Sonata\MediaBundle\Provider;

use Sonata\MediaBundle\Provider\ImageProvider as BaseImageProvider;
use Sonata\AdminBundle\Form\FormMapper;
use Gaufrette\Filesystem;
use Imagine\Image\ImagineInterface;
use Sonata\CoreBundle\Model\Metadata;
use Sonata\MediaBundle\CDN\CDNInterface;
use Sonata\MediaBundle\Generator\GeneratorInterface;
use Sonata\MediaBundle\Metadata\MetadataBuilderInterface;
use Sonata\MediaBundle\Model\MediaInterface;
use Sonata\MediaBundle\Thumbnail\ThumbnailInterface;
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Form\Form;

/**
 * Overrides the default provider to add the url field in the admin form
 *
 * @author christophe Ferreboeuf <christophe@codivores.com>
 */
class ImageProvider extends BaseImageProvider{

    /**
     * 
     * @param FormMapper $formMapper
     */
    public function buildCreateForm(FormMapper $formMapper)
    {
        $formMapper->add('binaryContent', array(), array('type' => 'string'));
    }

    /**
     * 
     * @param FormMapper $formMapper
     */
    public function buildEditForm(FormMapper $formMapper)
    {
        $formMapper->add('name');
        $formMapper->add('enabled');
        $formMapper->add('authorName');
        $formMapper->add('url');
        $formMapper->add('cdnIsFlushable');
        $formMapper->add('description');
        $formMapper->add('copyright');
        $formMapper->add(
            'binaryContent',
            // NEXT_MAJOR: Remove ternary and keep 'Symfony\Component\Form\Extension\Core\Type\FileType' value
            // (when requirement of Symfony is >= 2.8)
            method_exists('Symfony\Component\Form\AbstractType', 'getBlockPrefix')
                ? 'Symfony\Component\Form\Extension\Core\Type\FileType'
                : 'file',
            array('required' => false)
        );
    }
}

并在您的服务上声明它（我更喜欢 yml）：

sonata.media.provider.image:
     class: Application\Sonata\MediaBundle\Provider\ImageProvider
     arguments:
        - sonata.media.provider.image
        - @sonata.media.filesystem.local
        - @sonata.media.cdn.server
        - @sonata.media.generator.default
        - @sonata.media.thumbnail.format
        - []
        - []
        - @sonata.media.adapter.image.gd
        - @sonata.media.metadata.proxy
     tags:
        - { name: sonata.media.provider }
     calls:
        - [ setTemplates, [ { helper_thumbnail: SonataMediaBundle:Provider:thumbnail.html.twig, helper_view: SonataMediaBundle:Provider:view_image.html.twig } ] ]

【解决方案2】：

好吧，看来我必须删除 Application/Sonata/MediaBundle/Resources/config/doctrine 文件夹并将媒体实体注释如下：

<?php

namespace Application\Sonata\MediaBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Sonata\MediaBundle\Entity\BaseMedia as BaseMedia;

/**
 * @ORM\Table(name="media__media")
 * @ORM\Entity
 */
class Media extends BaseMedia

最后一个简单的php app/console doctrine:schema:update --force 就成功了。希望这对遇到同样问题的人有所帮助。
