【中文标题】Symfony 4 + 奏鸣曲管理包 + 关系。表单正在删除子项，但不仅是 parentId

【英文标题】：Symfony 4 + sonata admin bundle + relations. Form is deleting children but not only parentId

【发布时间】：2021-07-30 11:27:19

【问题描述】：

大家好！我遇到了一些问题。我有奏鸣曲管理员 + symfony 4 + 一些具有多面关系的实体。我有 3 个名为banner videobanner photobanner 的简单表格，现在我想创建管理部分，它将由 1 2 或 3 个简单的横幅视频横幅或 photobbanner 创建。它几乎完成了，但表格有一些错误。我可以创建简单的横幅，并且可以成功创建记录，但是 parentId 是空的，因为它现在没有任何父母，但是后来当我在管理员中设置时 parentId 正在子表中创建，但后来当我尝试删除关系奏鸣曲管理员用子记录删除它，但我希望奏鸣曲管理员只删除 parentId 子记录必须保留 parentId = NULL。

【参考方案1】：

考虑看看奏鸣曲的saving hooks。

您似乎已经在使用preUpdate() 函数，并且可以利用preRemove() 函数来实现您正在寻找的内容。

您可能还必须从您的实体中删除 onDelete="CASCADE"。

【讨论】：

是的，preUpdate 工作正常，但 preRemove - 不行。删除了 onDelete="CASCADE" 但现在当我试图从管理员中删除它时，表单不会保存关系更改。

在 preRemove 中，您是否尝试添加类似 $parent->getChildren(); 的内容，然后循环遍历它们并将每个子对象的父对象设置为 NULL？
