rails_admin + dropzone.js + mongoid(embedded)

Installation

Add this line to your application's Gemfile:

gem 'rails_admin_multiple_file_upload'

And then execute:

$ bundle

Usage with rails_admin

Add the sort_embedded action for each model or only for models you need

    RailsAdmin.config do |config|
      config.actions do
        ......
        multiple_file_upload do
          visible do
            %w(Page).include? bindings[:abstract_model].model_name
          end
        end
      end
    end

In embedded model:

    has_mongoid_attached_file :image, styles: {main: "1000x1000>"}

In rails_admin block for parent model:

    multiple_file_upload(
        {
            fields: [:my_news_images],
            thumbnail_size: :main #default :thumb
        }
    )
