Easy to use integration of drag&drop files upload via dropzone.js for rails_admin

Add in Gemfile

gem 'rails_admin_dropzone'

• Test with rails < 5 and TurboLink < 5

class Album < ActiveRecord::Base
  has_many :photos
end

class Photo < ActiveRecord::Base
  belongs_to :album
end

Add this method create_associated_image in your model, example Album, that will contain the upload images and change the associations and attributes

class Album < ActiveRecord::Base
  has_many :photos

  # Method
  def create_associated_image(image)
    photos.create(image: image)
  end
end

Add in config/initialisers/rails_admin.rb

RailsAdmin.config do |config|
  config.actions do
    dashboard
    index
    new

    dropzone do
      only YOUR_MODEL # Example Album
    end

    show
    edit
    delete
  end
end

and "Voalá"
