我有一个 Rails 4 应用程序。我正在尝试在 S3 上为不同的重新文件上传者创建一个子文件夹系统。我尝试了下面的代码，但没有成功。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？

日志：

20:24:09 puma.1    | Started GET "/attachments/refile_caches_backend/presign?t=1459707849942.0" for ::1 at 2016-04-03 20:24:09 +0200

重新文件.rb

require "refile/s3"

aws = {
  access_key_id: ENV['AWS_ACCESS_KEY_ID'],
  secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
  region: "us-east-1",
  bucket: ENV['S3_BUCKET_NAME']
}

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']

消息.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，但我无法用 配置缓存Refile.backends，所以我就让它保持原样，因为那部分似乎并不重要。

对于后端配置工作的存储，文件被上传到所需的子文件夹。

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
