Symfony多数据库捆绑

Question

我的应用程序symfony管理视频和视频评论，因此我有两个捆绑包videoBundle和commentBundle。

在我的应用程序symfony中，我使用多个数据库连接，每个客户都连接到他的数据库。

这是我的Video.orm.yml

VideoBundle\Entity\Video:
type: entity
table: null
repositoryClass: VideoBundle\Repository\VideoRepository
id:
    id:
        type: integer
        id: true
        generator:
            strategy: AUTO
fields:
    fileTitle:
        type: string
        length: 255
        column: file_title
        nullable: true
    title:
        type: string
        length: 255
  ...
oneToMany:
    comments:
        targetEntity: CommentBundle\Entity\Comment
        mappedBy: video
        cascade: ["persist","remove","merge"]
        joinColumn:
            onDelete: CASCADE

这是我的Comment.orm.yml

CommentBundle\Entity\Comment:
type: entity
table: null
repositoryClass: CommentBundle\Repository\CommentRepository
id:
    id:
        type: integer
        id: true
        generator:
            strategy: AUTO
fields:
    texte:
        type: string
        length: 255
manyToOne:
    video:
      targetEntity: VideoBundle\Entity\Video
      cascade:      ["persist"]
      inversedBy: comments
      joinColumn:
        name: video_id
        referencedColumnName: id
        onDelete: "CASCADE"
        options:
            comment: Video Id

这是我的配置管理器：

我想为某些客户使用这种关系，并希望在某些客户中使用无评论的视频。

客户如何使用无评论的视频，没有捆绑的commentBundle。

我该怎么做？
