关于插入的Symfony fk问题

Question

我发布了类似的问题,但无法解决.我创建了一个用户和组的关系数据库,但由于某种原因,我无法正确插入测试数据.以下是架构的示例:

User:
  actAs: { Timestampable: ~ }
  columns:
    name: { type: string(255), notnull: true }
    email: { type: string(255), notnull: true, unique: true }
    nickname: { type: string(255), unique: true }
    password: { type: string(300), notnull: true }
    image: { type: string(255) }

Group:
  actAs: { Timestampable: ~ }
  columns:
    name: { type: string(500), notnull: true }
    image: { type: string(255) }
    type: { type: string(255), notnull: true }
    created_by_id: { type: integer }
  relations: 
    User: { onDelete: SET NULL, class: User, local: created_by_id, foreign: id, foreignAlias: groups_created }

FanOf:
  actAs: { Timestampable: ~ }
  columns:
    user_id: { type: integer, primary: true }
    group_id: { type: integer, primary: true }
  relations:
    User: { onDelete: CASCADE, local: user_id, foreign: id, foreignAlias: fanhood }
    Group: { onDelete: CASCADE, local: group_id, foreign: id, foreignAlias: fanhood }

这是我尝试输入的数据:

User:
  user1:
    name: Danny
    email: comedy19@gmail.com
    nickname: danny
    password: f05050400c5e586fa6629ef497be

Group:
  group1:
    name: Mets
    type: sports

FanOf:
  fans1:
    user_id: user1
    group_id: group1

我一直收到这个错误:

  SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`krowdd`.`fan_of`, CONSTRAINT `fan_of_user_id_user_id` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE)  

用户和群组显然是在"粉丝"之前创建的,为什么我会收到此错误？

谢谢!

Answer 1

在你的灯具文件中:

FanOf:
  fans1:
    user_id: user1
    group_id: group1

应该

FanOf:
  fans1:
    User: user1
    Group: group1

使用user_id和group_id,Doctrine需要一个整数值.如果使用关系名称,则可以传递在夹具中其他位置创建的"对象".
