Rails教程第11章Carrierwave和Cloudinary。 Heroku应用程序错误

Question

我正在关注Rails教程，不要使用AWS，因为我没有信用卡。

所以我尝试使用Cloudinary。

我是一个完整的noob在这里，我甚至不知道它是否可以完成。 重点是我想dephu我的网站上heroku，我可以上传图片。

它通过本地主机工作正常，但在Heroku此错误：

# encoding: utf-8 

class PictureUploader < CarrierWave::Uploader::Base 

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

    include CarrierWave::MiniMagick

    include Cloudinary::CarrierWave 


    # process :tags => ['post_picture'] 

# version :standard do 
# process :resize_to_fill => [200, 300, :north] 
# end 

# version :thumbnail do 
# resize_to_fit(50,50) 
# end 

# def public_id 
# return model.short_name 
# end 

    # Choose what kind of storage to use for this uploader: 
    if Rails.env.production? 
    #storage :cloudinary 
    storage :fog 
    else 
    storage :file 
    end 


    # 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 

通过本地主机，它工作正常。

在heroku上，它根本没有显示。
