Question

我有两个实体：用户和学生。以下是yaml架构：

ABC\UserBundle\Entity\User:
  type: entity
  table: abc_user
  id:
    id:       { type: integer, generator: { strategy: AUTO } }
  fields:        
    username: { type: string, length: 255, notnull: true, unique: true }
    email:    { type: string, length: 255, notnull: true, unique: true }
    password: { type: string, length: 255, notnull: true }
    enabled:  { type: boolean }


ABC\UserBundle\Entity\Student:
  type: entity
  table: abc_student
  id:
    id: { type: integer, generator: { strategy: AUTO } }        
  fields:
    first_name: { type: string, length: 255, notnull: true }
    middle_name: { type: string, length: 255 }
    last_name: { type: string, length: 255, notnull: true }
  OnetoOne:
    user:
      targetEntity: ABC\UserBundle\Entity\User

我的问题是，当我执行“doctine：update：schema --dump-sql”时，user_id字段未添加到Student表中，并且实体之间没有创建任何关系。

Answer 1

Yaml映射区分大小写，使用正确的名称oneToOne来创建关系。

Answer 2

您缺少OneToOne关联的joinColumn选项：

ABC\UserBundle\Entity\User:
  type: entity
  table: abc_user
  id:
    id:       { type: integer, generator: { strategy: AUTO } }
  fields:        
    username: { type: string, length: 255, notnull: true, unique: true }
    email:    { type: string, length: 255, notnull: true, unique: true }
    password: { type: string, length: 255, notnull: true }
    enabled:  { type: boolean }
  OnetoOne:
    student:
      targetEntity: ABC\UserBundle\Entity\Student
      mappedBy: user

ABC\UserBundle\Entity\Student:
  type: entity
  table: abc_student
  id:
    id: { type: integer, generator: { strategy: AUTO } }        
  fields:
    first_name: { type: string, length: 255, notnull: true }
    middle_name: { type: string, length: 255 }
    last_name: { type: string, length: 255, notnull: true }
  OnetoOne:
    user:
      targetEntity: ABC\UserBundle\Entity\User
      joinColumn:
        name: user_id
        referencedColumnName: id

symfony2架构的问题yaml：无法使关系正常工作
