从本地回形针存储S3迁移 [英] Migrating from local paperclip storage to S3

问题描述

最近，我们搬到一个新的虚拟主机提供商，提供有限的存储空间，所以我们正在努力将所有我们通过回形针宝石到Amazon S3上传用户上传（头像，文件等）。我有几百个文件都对应不同的模式，我现在想迁移集体。

We've recently moved to a new webhost that offers limited storage space so we're trying to move all of our user uploads (Avatars, Files, etc.) uploaded via the Paperclip gem to Amazon S3. I have several hundred files all corresponding to different models that I'm now trying to migrate en masse.

我发现本文，介绍了一个漂亮的回形针rake任务：

I found this document that introduces a nifty paperclip rake task:

耙回形针：刷新：missing_styles

此命令做了一些对我的工作，但是，我发现这只是建立文件结构不发送任何数据 - 除了它不设置使用定义的任何缩略图：风格散在 has_​​attached_file 通话。也就是说，我有以下回形针安装在我的车型之一：

This command does some of the work for me, however, I noticed it's only setting up the files structure without sending any data - in addition it's not setting up any thumbnails defined using the :styles hash in the has_attached_file call. I.e., I have the following paperclip setup on one of my models:

class User < ActiveRecord::Base
  has_attached_file :avatar,
    :styles => {
      :thumb => "100x100#",
      :small  => "150x150>",
      :medium => "200x200" }
end

下面是一些示例输出运行命令后：

Here's some sample output after running the command:

$ rake paperclip:refresh:missing_styles
Regenerating User -> avatar -> [thumb, :small, :medium]
Regenerating Mercury::Image -> image -> [:medium, :thumb]
Regenerating Profile -> image -> [:home_feature, :large, :medium, :thumb]
Regenerating Page -> preview -> [:portfolio]
Regenerating Category -> default_image -> [:home_feature, :large, :medium, :thumb]

导航到我的S3存储我可以看到所有的目录都被正确安装，并为每个连接，但只适用于原始图像文件，它们都是0字节。我误解这个命令的用法？我找不到任何其他工具来上传批量文件的整个目录到S3，如果有一个安全的工具，在那里，然后我打开耳朵已经涵盖了这无需付款。我试着建立一个Ruby脚本插入到自己的SDK和手动上传这些文件，但它们的Ruby文档也不是很大。

Navigating to my S3 Bucket I can see all the directories are correctly setup and for each attachment, but only for original image files and they're all 0 bytes. Am I misunderstanding the usage of this command? I couldn't find any other tool for uploading entire directories of files in bulk to S3, if there's a safe tool out there that already covers this without requiring payment then I'm open ears. I've tried building a ruby script to plug into their SDK and upload these files manually, but their Ruby documentation isn't great.

推荐答案

看起来像我需要超越的红宝石就这一个， s3cmd 似乎是对这种作业的最合适的工具。在我的例子中，同步命令的伎俩：

Looks like I needed to go beyond ruby on this one, s3cmd seemed to be the most appropriate tool for this sort of job. In my case, the sync command did the trick:

s3cmd sync my-app/public/system/ s3://mybucket
