带有refile的rails S3子文件夹

Question

我有一个rails 4应用程序。我正在尝试在S3上为不同的refile上传程序创建一个子文件夹系统。我尝试了下面的代码，但它不能工作。没有任何内容上传到S3，也没有显示在应用程序中。

我错过了什么？

  secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],

message_files = aws.merge({bucket: "message_files"})
product_files = aws.merge({bucket: "product_files"})
refile_caches = aws.merge({bucket: "refile_caches"})

Refile.backends["message_files_backend"] = Refile::S3.new(prefix: "store", **message_files)
Refile.backends["product_files_backend"] = Refile::S3.new(prefix: "store", **product_files)
Refile.backends["refile_caches_backend"] = Refile::S3.new(max_size: 5.megabytes, prefix: "cache", **refile_caches)
Refile.cdn_host = ENV['CLOUDFRONT_URL']

message.rb

class Message < ActiveRecord::Base
  attachment :message_attachment, store: 'message_files_backend', cache: 'refile_caches_backend' ,extension: ["pdf", "doc", "docx", "xls", "xlsx", "html", "png", "img", "jpg"]
end

我不知道为什么，但是我不能用Refile.backends配置缓存，所以我就让它保持原样，因为这部分似乎并不重要。

对于后端配置有效的存储，文件将上载到所需的子文件夹。

Refile.backends["message_files_backend"] = Refile::S3.new(prefix: "store/message_files", **aws)
Refile.backends["product_files_backend"] = Refile::S3.new(prefix: "store/product_files", **aws)
Refile.cache = Refile::S3.new(max_size: 5.megabytes, prefix: "cache", **aws)

#in the model thanks to using the default cache it doesn't have to be defined
class Message < ActiveRecord::Base
  attachment :message_attachment, store: 'message_files_backend', extension: ["pdf", "doc", "docx", "xls", "xlsx", "html", "png", "img", "jpg"]
end
