Doctrine2-如何不按id設置oneToOne實體

Question

這是映射信息的一部分：

id:
    type: integer
    id: true
    generator:
        strategy: AUTO
ms_id:
    type: string
    unique: true
oneToOne:
    parent:
        targetEntity: Category
        nullable: true

如何使用ms_id而非id建立連接

Answer 1

您可以使用referencedColumnName指定連接列參數，請參閱關聯映射文檔

id:
    type: integer
    id: true
    generator:
        strategy: AUTO
ms_id:
    type: string
    unique: true
oneToOne:
    parent:
        targetEntity: Category
        joinColumn:
          name: category_id
          referencedColumnName: ms_id
        nullable: true
