获取磁盘上 ActiveStorage 文件的路径 [英] Get path to ActiveStorage file on disk

问题描述

我需要获取磁盘上使用 ActiveStorage 的文件的路径.该文件存储在本地.

I need to get the path to the file on disk which is using ActiveStorage. The file is stored locally.

当我使用回形针时，我在返回完整路径的附件上使用了 path 方法.

When I was using paperclip, I used the path method on the attachment which returned the full path.

示例:

user.avatar.path

在查看 Active Storage Docs 时，它看起来像 rails_blob_path 可以解决问题.在查看它返回的内容后，它没有提供文档的路径.因此，它返回此错误:

While looking at the Active Storage Docs, it looked like rails_blob_path would do the trick. After looking at what it returned though, it does not provide the path to the document. Thus, it returns this error:

没有那个文件或目录@rb_sysopen -

No such file or directory @ rb_sysopen -

背景

我需要文档的路径，因为我正在使用 combine_pdf gem 来组合多个 pdf成一个单一的pdf.

I need the path to the document because I am using the combine_pdf gem in order to combine multiple pdfs into a single pdf.

对于回形针实现，我遍历所选pdf附件的full_paths并将它们load到组合的pdf中:

For the paperclip implementation, I iterated through the full_paths of the selected pdf attachments and load them into the combined pdf:

attachment_paths.each {|att_path| report << CombinePDF.load(att_path)}

推荐答案

感谢@muistooshort 在评论中的帮助，查看了活动存储代码，这是有效的:

Thanks to the help of @muistooshort in the comments, after looking at the Active Storage Code, this works:

active_storage_disk_service = ActiveStorage::Service::DiskService.new(root: Rails.root.to_s + '/storage/')
active_storage_disk_service.send(:path_for, user.avatar.blob.key)
  # => returns full path to the document stored locally on disk

这个解决方案对我来说有点棘手.我很想听听其他解决方案.不过这对我有用.

This solution feels a bit hacky to me. I'd love to hear of other solutions. This does work for me though.
