Symfony oneToMany/ManyToOne双向关联未在doctrine2中生成联接列

我试图在一个表中创建两个一对一的关系。但是，当我生成enities时，连接列不会在Foo实体上生成。这是我的yaml：

User.orm.yml

Acme\SomeBundle\Entity\User:
  type: entity
  table: user
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    firstname:
      type: string
      length: 40
    created_at:
      type: datetime
      gedmo:
        timestampable:
          on: create
    updated_at:
      type: datetime
      gedmo:
        timestampable:
          on: update
  oneToMany:
    foos:
      targetEntity: Foo
      mappedBy: user

Acme\SomeBundle\Entity\Artist:
  type: entity
  table: artist
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    name:
      type: string
      length: 100
  oneToMany:
    foos:
      targetEntity: Foo
      mappedBy: artist

Acme\SomeBundle\Entity\Foo:
  type: entity
  table: foo
  id:
    id:
      type: integer
      generator:

  fields:
    created_at:
      type: datetime
      gedmo:
        timestampable:
          on: create
    updated_at:
      type: datetime
      gedmo:
        timestampable:
          on: update
  ManyToOne:
    artist:
      targetEntity: Artist
      inversedBy: foos
    user:
      targetEntity: User
      inversedBy: foos

Artist.orm.yml

  oneToMany:
    foos:
      targetEntity: Foo
      mappedBy: user

Acme\SomeBundle\Entity\Artist:
  type: entity
  table: artist
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:

      type: string
      length: 100
  oneToMany:
    foos:
      targetEntity: Foo
      mappedBy: artist

Acme\SomeBundle\Entity\Foo:
  type: entity
  table: foo

      inversedBy: foos
    user:
      targetEntity: User
      inversedBy: foos

Foo.orm.yml

Acme\SomeBundle\Entity\User:
  type: entity
  table: user
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    firstname:
      type: string
      length: 40
    created_at:
      type: datetime
      gedmo:
        timestampable:
          on: create
    updated_at:
      type: datetime
      gedmo:
        timestampable:
          on: update
  oneToMany:
    foos:
      targetEntity: Foo
      mappedBy: user

Acme\SomeBundle\Entity\Artist:

      type: string
      length: 100
  oneToMany:
    foos:
      targetEntity: Foo
      mappedBy: artist

Acme\SomeBundle\Entity\Foo:
  type: entity
  table: foo
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    created_at:
      type: datetime
      gedmo:
        timestampable:
          on: create
    updated_at:
      type: datetime
      gedmo:
        timestampable:
          on: update
  ManyToOne:
    artist:
      targetEntity: Artist
      inversedBy: foos
    user:
      targetEntity: User
      inversedBy: foos

Foo表上仅创建id、created_at和updated_at列，同时还应创建两个join列。我还尝试在yaml文件中手动定义联接列，但是我认为这不必要

有人找到线索了吗？

Pfff原来是许多人的大写字母M。应该是
