The problem

Initially asked at RORO but I will elaborate with an example.

What we need to do is the following:

• we list a set of items (let's say posts) and want to show a drop-down menu next to each one (quick example)
• when the drop-down arrow is clicked the menu is loaded from the server.

  class CloudinaryUpload < Struct.new(:uploader_class, :model, :field, :file_name, :content_type, :data)
    include Logging

    def upload
      uploader = uploader_class.new(model, field)
      store = Cloudinary::CarrierWave::Storage.new(uploader)
      io = Cloudinary::Blob.new(data, original_filename: file_name, content_type: content_type)
      uploader.cache!(io)
      store.store!(uploader.file)
