将Paperclip路径文件名从服务器更新到s3(Updating Paperclip path file names from on server to s3)

我有一个回形针实例，我将我的文件迁移到另一个区域。最初文件存储在我的服务器上，只根据创建的记录的id和原始id给出了文件名。现在我将它们移动到s3并希望更新文件名以使其正常工作。我设置了我的回形针配置，如下所示：

:path => ":class/:attachment/:hash-:style.:extension",

:url => ":s3_domain_url",

:hash_secret => SECRET,

:hash_data => ":class/:attachment/:id/:updated_at"

我更新了我的文件的原始记录文件名是唯一的，并将它们移动到我的s3实例。不幸的是现在我无法从s3下载文件，我认为这是因为paperclip使用了错误的文件名路径。一个基于路径默认值的，现在使用我的配置文件设置。我希望能够更新我的文件file_name字段，以便新文件的路径正确，我可以适当地下载它们。有没有办法直接根据我的秘密和hash_data调用回形针散列函数，这样我就可以更新那些file_name字段并能够立即提取这些记录？自从我的原始服务器移动后上传的所有内容似乎都正常工作。

I have a paperclip instance that I am migrating my files to a different area. Originally the files were stored on my server and just given a filename based on the id of the record created and the original id. Now I'm moving them to s3 and want to update the filenames to work appropriately. I setup my paperclip config like so:

:path => ":class/:attachment/:hash-:style.:extension",

:url => ":s3_domain_url",

:hash_secret => SECRET,

:hash_data => ":class/:attachment/:id/:updated_at"

I updated the original records filenames for my files to be unique and moved them over to my s3 instance. Unfortunately now I am unable to pull down the files from s3 and I think it is because paperclip is using the wrong path for the filenames. One that is based off the path default that is now set using my config file. I want to be able to update my files file_name field so that the path is correct for the new files and I am able to download them appropriately. Is there a way to call paperclips hashing function based on my secret and hash_data directly so I can update those file_name fields and be able to pull those records now? Everything that has been uploaded since the move from my original servers seems to work appropriately.

最满意答案

假设您有一个名为profile_pic的附件的模型用户 ;

进入rails控制台，例如。 rails c然后获取你有附件的模型的对象，例如。 u = User.find(100) 。

现在输入u.profile_pic.url以获取url或u.profile_pic_file_name以获取文件名。

要查看其他选项(例如旧选项)的效果，您可以执行此操作;

p = u.profile_pic # gets the paperclip attachment for profile_pic

puts p.url # gets the current url

p.options.merge!(url: '/blah/:class/:attachment/:id_partition/:style/:filename')

puts p.url # now shows url with the new options

类似地， p.path将显示本地文件路径，其中包含您选择的任何选项。

长话短说，有点像;

User.where('created_at < some_date').map do |x|

"#{x.id} #{x.profile_pic_file_name} #{x.profile_pic.path}"

end

应该给你你想要的:)

Say you have a model User with an attachment named profile_pic;

Go into the rails console eg. rails c and then get an object for the model you have the attachment on, eg. u = User.find(100).

Now type u.profile_pic.url to get the url or u.profile_pic_file_name to get the filename.

To see the effect of other options (for example your old options) you can do;

p = u.profile_pic # gets the paperclip attachment for profile_pic

puts p.url # gets the current url

p.options.merge!(url: '/blah/:class/:attachment/:id_partition/:style/:filename')

puts p.url # now shows url with the new options

Similarly p.path will show the local file path with whatever options you pick.

Long story short, something like;

User.where('created_at < some_date').map do |x|

"#{x.id} #{x.profile_pic_file_name} #{x.profile_pic.path}"

end

should give you what you want :)
