ruby-on-rails-3 - 带有Rails CRUD的最佳音频上传

Question

我尝试在特定的Rails New simpleform中创建音频播放器。

一条简短的消息，我想发布带有音频按钮的翻转式抽认卡(实际上，我生成了平假名)，以使用音频播放器收听单词。

我在问什么是上传音频文件的最佳解决方案？
实际上，我尝试使用Cloudinary视频存储服务来做到这一点。

我使用CarrierWave gem创建一个声音上传器，如下所示:

# encoding: utf-8

class SoundUploader < CarrierWave::Uploader::Base
  include Cloudinary::CarrierWave

  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url
  #   # For Rails 3.1+ asset pipeline compatibility:
  #   # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
  #
  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process :scale => [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  # version :thumb do
  #   process :resize_to_fit => [50, 50]
  # end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  # def extension_white_list
  #   %w(jpg jpeg gif png)
  # end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here, see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end

end

然后在我的模型中，我使用以下代码调用MountUploader(我调用的对象是声音):

class Hiragana < ActiveRecord::Base
  belongs_to :user
  has_many :favs, dependent: :destroy

  mount_uploader :upload, ImageUploader

  mount_uploader :sound, SoundUploader

end

上载是在“查看新建”中创建的

我的问题是如何调用上传？我的意思是我将这个可变的 @hiragana.sound放入我的代码中，但可以看看错误图片[!

他的意思是你必须改变这个:

    # Choose what kind of storage to use for this uploader:
    storage :file
    # storage :fog

    def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    end

对此:

    # Choose what kind of storage to use for this uploader:
    # storage :file
    # storage :fog

    # def store_dir 
    #  "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    # end
