Symfony2 Doctrine多个manyToMany相同实体，yml文件之间的相关性

Question

我目前有一个正常运行的manyToMany关系。我想在相同的实体之间添加第二个manyToMany关系。但是，doctrine / symphony尝试创建一个具有相同名称的表，从而导致错误。我如何添加第二个关系？

YML文件原始关系

...
manyToMany:
    originFormDataObjects:
        targetEntity: SM\FormBundle\Entity\FormData
        mappedBy: targetFormDataObjects
        orderBy: { 'id': 'DESC' }
    targetFormDataObjects:
        targetEntity: SM\FormBundle\Entity\FormData
        inversedBy: originFormDataObjects
        orderBy: { 'id': 'DESC' }

添加关系的YML文件，导致错误

...
manyToMany:
    originFormDataObjects:
        targetEntity: SM\FormBundle\Entity\FormData
        mappedBy: targetFormDataObjects
        orderBy: { 'id': 'DESC' }
    targetFormDataObjects:
        targetEntity: SM\FormBundle\Entity\FormData
        inversedBy: originFormDataObjects
        orderBy: { 'id': 'DESC' }
    formDataObjects:
        targetEntity: SM\FormBundle\Entity\FormData

您可以尝试指定表名，如下所示：

manyToMany:
originFormDataObjects:
    targetEntity: SM\FormBundle\Entity\FormData
    mappedBy: targetFormDataObjects
    orderBy: { 'id': 'DESC' }
    joinTable:
      name: table_name
      joinColumns:
        fk_id:
          referencedColumnName: id
      inverseJoinColumns:
        inverse_id:
          referencedColumnName: id
