CKEditor Carrierwave Cloudinary

Estou tentando fazer com que o CKEditor trabalhe com a Carrierwave e a Cloudinary. Até agora, visualizações não-CKEditor ativadas com um campo de upload de arquivo regular estão funcionando perfeitamente com Carrierwave & Cloudinary. No entanto, quando eu tento fazer upload de um arquivo no CKEditor e "Enviar para o servidor" estou recebendo umNoMethodError - undefined method 'each' for "image/jpeg":String:

Antes de remover a configuração de armazenamento local das classes CKEditor, estava funcionando, mas salvando o arquivo localmente.

Aqui está meu uploader atual do CKEditor:

class CkeditorAttachmentFileUploader < CarrierWave::Uploader::Base
  include Cloudinary::CarrierWave
  include Ckeditor::Backend::CarrierWave

  def extension_white_list
    Ckeditor.attachment_file_types
  end
end

Arquivo de log:

Qualquer idéia apreciada!

UPDATE - Configuração de trabalho da resposta de Tal Lev-Ami

Esta é a minha atual, trabalhandockeditor_picture_uploader.rb Arquivo:

# encoding: utf-8
class CkeditorPictureUploader < CarrierWave::Uploader::Base
  include Ckeditor::Backend::CarrierWave
  include Cloudinary::CarrierWave

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

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

  # 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/ckeditor/pictures/#{model.id}"
  # end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url
  #   "/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

  [:extract_content_type, :set_size, :read_dimensions].each do |method|
    define_method :"#{method}_with_cloudinary" do
      send(:"#{method}_without_cloudinary") if self.file.is_a?(CarrierWave::SanitizedFile)
      {}
    end
    alias_method_chain method, :cloudinary
  end

  process :read_dimensions

  # Create different versions of your uploaded files:
  version :thumb do
    process :resize_to_fill => [118, 100]
  end

  version :content do
    process :resize_to_limit => [800, 800]
  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
    Ckeditor.image_file_types
  end
end
