我发布了一个类似的问题,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,我无法正确插入带有夹具的测试数据。这是架构的示例:

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

我不断收到此错误:

  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)  

用户和组显然是在“狂热”之前创建的,所以为什么我会收到这个错误?

谢谢!

在您的设备文件中:

FanOf:
  fans1:
    user_id: user1
    group_id: group1

应该

FanOf:
  fans1:
    User: user1
    Group: group1

使用user_idand group_id,Doctrine 需要一个整数值。如果您使用关系名称,您可以将您在夹具中其他地方创建的“对象”传递给您。
