Question

更新：可能存在阻止此配置的gem。这些宝石中没有一个看起来像匪徒，但如果有人认为他们发现了一个，请告诉我。谢谢！

在这里使用Rails 3。我有两个模特。

class Contact < ActiveRecord::Base
  has_many :invitations, dependent: :destroy
end

class Invitation < ActiveRecord::Base
  belongs_to :contact
end

当我运行以下内容时..

contact = Contact.first // has associated invitations 

contact.destroy

联系人已被销毁，但邀请却没有。当我查看日志时，我看到以下sql查询打印输出..

  Invitation Load (0.2ms)  SELECT `invitations`.* FROM `invitations` WHERE `invitations`.`contact_id` = 51
   (0.4ms)  BEGIN
   (0.6ms)  UPDATE `contacts` SET `deleted_at` = '2016-02-25 13:05:38', `updated_at` = '2016-02-25 13:05:38' WHERE `contacts`.`id` = 51
   (1.2ms)  COMMIT

当我查看数据库时，邀请记录仍然存在。

此代码有什么问题，如何解决？

Answer 1

我认为你的应用中的某个人可能已经通过模型中的方法或gem来覆盖destroy的工作方式。检查

之类的内容

  def destroy
    self.update_attributes(deleted_at: DateTime.current)
  end

如果有类似的东西，你必须覆盖它。我首先查看db：schema中带有“deleted_at”列的所有表，然后使用super向这些模型添加destroy方法来调用ActiveRecord :: Base destroy方法。

Answer 2

这是由于它用于逻辑删除的偏执宝石。你可以通过以下代码从db中删除

 contact = Contact.first // has associated invitations 
 contact.really_destroy!

有许多依赖性破坏不会破坏记录
