Carrierwave - 仅在已从存储中删除已装入的文件后销毁对象

Question

Carrierwave在对象销毁完成后删除文件:

after_commit :remove_avatar! :on => :destroy

https://github.com/carrierwaveuploader/carrierwave

我有一个删除文件的工人.如果其中一个工作人员在从S3删除文件时超时,我将失去对S3上文件的跟踪并且我的存储桶变得一团糟(因为我的对象已经安装的文件从我的数据库中消失了).

我该怎么处理？remove_avatar!在我之前直接打电话object.destroy然后skip_callback?安全吗？

Answer 1

class User < ActiveRecord::Base
  mount_uploader :avatar, AvatarUploader

  before_destroy :clean_s3

private
  def clean_s3
    avatar.remove!
    avatar.thumb.remove! # if you have thumb version or any other version
  rescue Excon::Errors::Error => error
    puts "Something gone wrong"
    false
  end
end
