CKEditor Carrierwave Cloudinary

Question

I'm trying to get CKEditor to work with Carrierwave and Cloudinary. So far, non-CKEditor enabled views with a regular file upload field are working perfectly with Carrierwave & Cloudinary. However, when I try to upload a file in CKEditor and "Send it to the Server" I'm getting a NoMethodError - undefined method 'each' for "image/jpeg":String:

Prior to removing the local storage config from the CKEditor classes it was working, but saving the file locally.

Here is my current CKEditor uploader:

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

  def extension_white_list
    Ckeditor.attachment_file_types
  end
end

NoMethodError - undefined method `each' for "image/jpeg":String:

Any ideas appreciated!

UPDATE - Working config from Tal Lev-Ami answer

This is my current, working ckeditor_picture_uploader.rb file:

# 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

Answer 1

Try to add the following code to your CkPictureUploader/CkeditorAttachmentFileUploader:

[:extract_content_type, :extract_size, :extract_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

Answer 2

Ckeditor was updated so this may need to be extract_size and extract_dimensions depending on ckeditor gem version

Commit Where it was changed: https://github.com/galetahub/ckeditor/blob/4e6d8413cc71f40d2d58ab3d0cb8dad19dd96894/lib/ckeditor/backend/carrierwave.rb

ie:

[:extract_content_type, :extract_size, :extract_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
