触发相关的：破坏与覆盖破坏法 [英] Triggering dependent: :destroy with overridden destroy-method

问题描述

在我们的应用程序，我们已经覆盖了ActiveRecord的销毁方法，使我们的记录不被删除（这样用户可以取消）。像这样：

In our application we've overridden the ActiveRecord destroy method so that our records do not get deleted (so the user can undelete). Like so:

def destroy
  self.is_deleted = true
  self.save
  freeze
end

不过，这似乎已禁用依赖破坏我们的的has_many 的关系。换句话说，如果破坏被称为父对象上的的has_many 不被摧毁的子对象（其不被删除，即SQL'删除... '，也不是重写灭 -method称为）。

However, this seems to have disabled the dependent destroy on our has_many relationships. In other words, if destroy is called on a parent object, the child objects of has_many do not get destroyed (they don't get deleted, i.e, SQL 'DELETE...', nor is the overridden destroy-method called).

我如何触发子对象的破坏。

How do I trigger the destruction of the child objects.

谢谢！

推荐答案

您需要触发销毁回调。

def destroy
  self.is_deleted = true
  self.save
  run_callbacks :destroy
  freeze
end
