问题描述

我不能让onDelete在Doctrine2(使用YAML映射)中工作。



我在 Product class:

  oneToOne:
类别:
targetEntity:类别
onDelete:CASCADE

但这不行。



编辑:



我已经在数据库中手动设置了 ON DELETE:CASCADE p>

使用 doctrine导入YAML映射:mapping:import



清空数据库



使用 doctrine:schema:update 从架构更新它,并且没有 ON DELETE 在外键..所以看起来甚至Doctrine不知道该怎么做哈哈..

解决方案

好的,得到了​​!我必须在 joinColumn 中使用 onDelete

  oneToOne:
类别:
targetEntity:类别
joinColumn:
onDelete:CASCADE


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..

解决方案

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

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