将 onDelete 与原则 2 一起使用

发布于 2024-12-18 13:36:56 字数 472 浏览 4 评论 0原文

我无法让 onDelete 在 Doctrine2 中工作（使用 YAML 映射）。

我在我的 Product 类中尝试了这种关系：

oneToOne:
    category:
      targetEntity: Category
      onDelete: CASCADE

但这不起作用..

编辑：

的数据库中手动设置 ON DELETE: CASCADE

我已在导入 YAML 映射使用doctrine:mapping:import，

清空数据库，

使用doctrine:schema:update从架构中更新它，并且在外部没有ON DELETE关键..看起来如此就像甚至 Doctrine 都不知道该怎么做，哈哈..

I can't get the onDelete to work in Doctrine2 (with YAML Mapping).

I tried this relation in my Product class:

oneToOne:
    category:
      targetEntity: Category
      onDelete: CASCADE

But that doesn't work..

EDIT:

I've set the ON DELETE: CASCADE manually in the database

imported the YAML mapping with doctrine:mapping:import,

emptied the database

updated it from the schema with doctrine:schema:update and got no ON DELETE in the foreign key.. so looks like even Doctrine doesn't know how to do it lol..

好的，明白了！我必须在 joinColumn 内使用 onDelete：

oneToOne:
    category:
        targetEntity: Category
        joinColumn:
            onDelete: CASCADE

OK, got it! I had to use onDelete inside joinColumn:

oneToOne:
    category:
        targetEntity: Category
        joinColumn:
            onDelete: CASCADE

这是joinTable中使用onDelete的方法：

manyToMany:
    parameters:
        targetEntity: Fox\LandingBundle\Entity\Parameter
        cascade: ["persist","remove"]
        joinTable:
            name: subscriberBox_parameter
            joinColumns:
                subscriberBox_id:
                    referencedColumnName: id
            inverseJoinColumns:
                parameter_id:
                    referencedColumnName: id
                    onDelete: CASCADE

This is the way to use onDelete in joinTable:

manyToMany:
    parameters:
        targetEntity: Fox\LandingBundle\Entity\Parameter
        cascade: ["persist","remove"]
        joinTable:
            name: subscriberBox_parameter
            joinColumns:
                subscriberBox_id:
                    referencedColumnName: id
            inverseJoinColumns:
                parameter_id:
                    referencedColumnName: id
                    onDelete: CASCADE
