将 onDelete 与 Doctrine 2 一起使用 [英] using onDelete with Doctrine 2

问题描述

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

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

我在我的 Product 类中尝试了这种关系:

I tried this relation in my Product class:

oneToOne:
    category:
      targetEntity: Category
      onDelete: CASCADE

但这不起作用..

我已经在数据库中手动设置了 ON DELETE: CASCADE

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

使用 doctrine:mapping:import 导入 YAML 映射，

imported the YAML mapping with doctrine:mapping:import,

清空数据库

使用 doctrine:schema:update 从架构更新它，并且在外键中没有 ON DELETE .. 所以看起来即使是 Doctrine 也不知道如何做吧哈哈..

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..

推荐答案

好的，明白了！我不得不在 joinColumn 内使用 onDelete:

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

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