ruby-on-rails - 如何防止回形针从 act_as_paranoid 模型中删除附件？

Question

我有一个模型，其中包含由回形针管理的几个不同的图像附件。最近我们改变了模型的行为，所以它可以被软删除并使用 act_as_paranoid 恢复。一切正常，除了当我们软删除模型时，回形针也会删除附件。

我已经浏览了回形针文档和代码，但我没有看到明显的方法来规避这一点。我希望能够告诉回形针忽略模型上的删除回调并保留附件？

Answer 1

回形针现在有 preserve_files选项。现在不需要覆盖。

File Preservation for Soft-Delete

An option is available to preserve attachments in order to play nicely with soft-deleted models. (acts_as_paranoid, paranoia, etc.)

has_attached_file :some_attachment, {
  :preserve_files => "true",
}

This will prevent some_attachment from being wiped out when the model gets destroyed, so it will still exist when the object is restored later.
