symfony固定装置：set ondelete：refclass表上的CASCADE

问题描述

我正在使用symfony 1.4.5，Doctrine 1.2和Mysql5。

I'm using symfony 1.4.5, Doctrine 1.2 and Mysql 5.

在我的schema.yml中，我有一些多对多关系可以正常工作大。但是我需要在联接表上具有onDelete：CASCADE。

In my schema.yml I have a few Many-to-Many relations which work great. But I need the joining table to have onDelete: CASCADE.

现在，对于学说，需要在外键存在的那一侧添加onDelete：CASCADE，但是由于refclass确实存在架构中没有任何关系。yml我无法。

Now for doctrine it is needed to add onDelete: CASCADE on the side where the foreignkey exists but since the refclass does not have any relations in the schema.yml I can't.

示例架构：

Organisatie:
  connection: doctrine
  tableName: organisatie
   columns:
    org_id:
     type: integer(4)
     fixed: false
     unsigned: false
     primary: true
     autoincrement: true
   naam:
     type: string(30)
     fixed: false
     unsigned: false
     primary: false
     notnull: true
     autoincrement: false
   relations:
     Sc:
      class: Sc
      refClass: ScRegel
      local: org_id
      foreign: sc_id

Sc:
  connection: doctrine
  tableName: sc
  columns:
    sc_id:
      type: integer(4)
      fixed: false
      unsigned: false
      primary: true
      autoincrement: true
      notnull: true
    sc_nummer:
      type: string(15)
      fixed: false
      unsigned: false
      primary: false
      autoincrement: false
      notnull: true
    type:
      type: string(20)
      fixed: false
      unsigned: false
      primary: false
      notnull: true
      autoincrement: false
  relations:
    Organisatie:
      class: Organisatie
      refClass: ScRegel
      local: sc_id
      foreign: org_id

 ScRegel:
  connection: doctrine
  tableName: sc_regel
  columns:
    sc_id:
      type: integer(4)
      primary: true
      autoincrement: true
      notnull: true
    sc_id:
      type: integer(4)
      fixed: false
      unsigned: false
      primary: false
      autoincrement: false
      notnull: true
    org_id:
      type: integer(4)
      fixed: false
      unsigned: false
      primary: false
      notnull: false
      autoincrement: false

现在我尝试添加onDelete：双方（Sc和Organisatie）的CASCADE，但是在这两种情况下，它们都被忽略，建立了联系，但是onDelete被忽略了。

Now i tried to add onDelete: CASCADE on both sides (Sc and Organisatie), but in both cases they are ignored, the relation is made, but the onDelete is ignored.

有人知道如何使它工作吗？

Does anybody know how to get this working?

推荐答案

实际上，我的原始答案是正确的。

Actually my original answer is in correct. Here is how I do it in an application I am building.

因此UserSearch有一个m-m连接表，称为SearchTag。但是我想将对UserSearch的删除级联到SearchTag表。

So UserSearch has a m-m join table called SearchTag. But I want to cascade my deletes of UserSearch to the SearchTag table.

因此，我明确定义了与SearchTag的关系，并将级联放置在该房地产上。

So I explicitly define the relationship to SearchTag and put the cascade on that realtionship.

我不喜欢使用ondelete，因为它意味着您可以在phpmyadmin等中破坏内容，因此使用 cascade：[delete]表示所有删除操作均由

I don't like using ondelete as it means you can break things in phpmyadmin etc, so using "cascade: [delete]" means all the deletes are handled by the application.

UserSearch:
  actAs: [Timestampable]
  columns:
    user_id:
      type: integer(4)
    update_minutes: integer(4)
    last_ran: integer
    next_run: integer
    running: boolean
  relations:
    Tags:
      class: Tag
      local: search_id
      foreign: tag_id
      refClass: SearchTag
    SearchTags:
      local: id
      foreign: search_id
      class: SearchTag
      type: many
      foreignType: one
      cascade: [delete]

SearchTag:
  columns:
    search_id: 
      type: integer
      primary: true
    tag_id: 
      type: integer
      primary: true

Tag:
  columns:
    name: {type: string(255), notnull: true}
  relations:
    Searches:
      class: UserSearch
      local: tag_id
      foreign: search_id
      refClass: SearchTag
    SearchTags:
      local: id
      foreign: tag_id
      class: SearchTag
      type: many
      foreignType: one
      cascade: [delete]
