rails如何获取镜像名称而不是shrine url的散列

Question

目前，当我使用shrine存储任何图像时，我会收到url :-

/uploads/store/90bcb5a78ed5de16a6c62eea1fb80ed1.png

但我希望url的显示方式如下：-

/uploads/store/original_image_name.png

有什么解决方案吗？

供参考：-

初始化器/shorine.rb

require "shrine/storage/file_system"
  Shrine.storages = {
    cache: Shrine::Storage::FileSystem.new("public", prefix: "uploads/cache"),
    store: Shrine::Storage::FileSystem.new("public", prefix: "uploads/store")
  }

model/image_uploader.rb

class ImageUploader < Shrine
  plugin :derivatives
  plugin :url_options, store: { host: "www.cloudfair.com" }
  Attacher.derivatives_processor do |original|
    processor = ImageProcessing::MiniMagick.source(original)
    {
      large:  processor.resize_to_limit!(1280, 800),
      medium: processor.resize_to_limit!(600, 600),
      small:  processor.resize_to_limit!(400, 400),
    }
  end
end

上传图片：-

photo = Photo.new
photo.image = params[:image_file]
photo.image_derivative!
photo.save()

要访问图像URL:-

photo.image(:small).url

您可以在您的上传程序文件中使用类似以下内容

def filename
  if original_filename
    "#{model.original_filename}.#{file.extension}"
  end
end
