Doctrine2 oneToMany 关系 yaml

发布于 2024-10-16 08:04:14 字数 527 浏览 3 评论 0原文

我有一个名为“Object”的实体，这是 yaml 代码：

Entities\Object:
  type: entity
  table: objects
  id:
    id:
      type: integer
      generator:
      strategy: AUTO
  fields:
    parent_id: 
      type : integer
  oneToOne:
    type:
      targetEntity: ObjectType
      joinColumn:
        name: type_id
        referencedColumnName: id

我想添加一个子父关系（oneToMany），但我不知道如何？我希望 mysql 表具有以下结构： id、type_id、parent_id 和实体具有这些选项 $object->getParent() （单个对象）和 $object->getChildren() （对象集合）。希望有人可以提供帮助，thnx

I have an entity called “Object”, here is the yaml code:

Entities\Object:
  type: entity
  table: objects
  id:
    id:
      type: integer
      generator:
      strategy: AUTO
  fields:
    parent_id: 
      type : integer
  oneToOne:
    type:
      targetEntity: ObjectType
      joinColumn:
        name: type_id
        referencedColumnName: id

I want to add a children parent relation (oneToMany) but I don’t know how? I want the mysql table to have following structure: id, type_id, parent_id and the entity to have those options $object->getParent() (single object) and $object->getChildren() (collection of objects) .
Hope someone can help, thnx

您正在尝试进行一对多、自引用，应该是这样的：

Entities\Objects:
  type: entity
  table: objects
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  oneToMany:
    children:
      targetEntity: Objects
      mappedBy: parent
  manyToOne:
    parent:
      targetEntity: Objects
      inversedBy: children
      joinColumn:
        name: parent_id
        referencedColumnName: id

看看手册关联映射

You're trying to do One-to-Many, self referencing, it should be something like that:

Entities\Objects:
  type: entity
  table: objects
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  oneToMany:
    children:
      targetEntity: Objects
      mappedBy: parent
  manyToOne:
    parent:
      targetEntity: Objects
      inversedBy: children
      joinColumn:
        name: parent_id
        referencedColumnName: id

Take a look at the manual Association Mapping
