Doctrine2:映射超类上的单对多 [英] Doctrine2: OneToMany on mapped superclass

问题描述

我的数据库结构如下:

工作:

• CTI表工作
• MappedSuperclass 表 AbstractImageWork 扩展了工作
• 决赛桌 PhotoWork 扩展了 AbstractImageWork

• CTI table Work
• MappedSuperclass table AbstractImageWork which extends Work
• final table PhotoWork which extends AbstractImageWork

评论:

• MappedSuperclass表评论
• 决赛桌WorkComment 扩展了Comment

WorkComment 与 Work 具有多对一关系:

WorkComment has a ManyToOne relation to Work:

@ManyToOne(targetEntity="Work", inversedBy="comments")

Work 与 WorkComment 有一对多的关系:

Work has a OneToMany relation to WorkComment:

@OneToMany(targetEntity="WorkComment", mappedBy="work")

问题是 Doctrine 在更新架构时给了我这个错误:

The problem is that Doctrine gives me this error while updating the schema:

[DoctrineORMMappingMappingException]
It is illegal to put an inverse side one-to-many or many-to-many association on
mapped superclass 'Acme...AbstractImageWork#comments'.

我猜这与卡在 Work 和 PhotoWork 之间的 MappedSuperclass AbstractImageWork 有关，但实际上我没有把这个关系放在 MappedSuperclass 上，但放在 CTI 表上..那么为什么 Doctrine 会这样呢?

I guess this has something to do with the MappedSuperclass AbstractImageWork stuck in the middle between Work and PhotoWork, but I didn't actually put this relation on the MappedSuperclass, but on the CTI table.. so why will Doctrine behave like this?

有什么想法吗?

推荐答案

在某些情况下，当您从标记为 @ORMMappedSuperclass 的类继承时出现此类错误，请尝试更改您的属性访问级别从私有到受保护

In some cases, when you have such error when inherit from the class that is tagged as @ORMMappedSuperclass, try to change your properties access level from private to protected
