必须配置路径“ fos_comment”的子节点“ db_driver”

Question

我遵循了您的文档，但出现了以下问题“必须配置路径“ fos_comment”处的子节点“ db_driver”。”

有人成功在此版本的Symfony上使用它吗？

我做了什么。

➡config / config.yaml

framework:
    http_method_override: true
    translator: ~

fos_comment:
    db_driver: orm
    class:
        model:
            comment: App\Entity\Comment
            thread: App\Entity\Thread

fos_comment_api:
    type: rest
    resource: "@FOSCommentBundle/Resources/config/routing.yml"
    prefix: /api
    defaults: { _format: html }

assetic:
    bundles: [ "FOSCommentBundle" ]

➡src / Entity / Comment.php

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use FOS\CommentBundle\Entity\Comment as BaseComment;

/**
 * @ORM\Entity
 * @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
 */
class Comment extends BaseComment
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * Thread of this comment
     *
     * @var Thread
     * @ORM\ManyToOne(targetEntity="App\Entity\Thread")
     */
    protected $thread;
}

➡src / Entity / Thread.php

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use FOS\CommentBundle\Entity\Thread as BaseThread;

/**
 * @ORM\Entity
 * @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
 */
class Thread extends BaseThread
{
    /**
     * @var string $id
     *
     * @ORM\Id
     * @ORM\Column(type="string")
     */
    protected $id;
}

➡templates / index.html.twig

我插入了这一部分：

{% include '@FOSComment/Thread/async.html.twig' with {'id': 'foo'} %}

没有别的，也没有作：migration。
