Attachment Magick¶ ↑

Attachment Magick is a gem to upload images and videos(vimeo and youtube) using swfupload. Supports Mongoid and ActiveRecord.

Installation¶ ↑

Add to Gemfile

gem 'attachment_magick'

After the gem installation, run the generator

rails g attachment_magick:install

The generator will install swfupload (js and css files) and will create some routes.

And if you are using ActiveRecord, run this too

rails g attachment_magick:migration

Create a initializer like this (config/initializers/attachment_magick_setup.rb)

AttachmentMagick.setup do |config|
  # config.default_add_partial = '/attachment_magick/add_image'  # default

  # You can set grid size manually:
    config.columns_amount = 16
    config.columns_width  = 52
    config.gutter         = 8
  # Or with our magick :)
  # config.parse_stylesheet('name_of_my_grid_file.css')

  config.orms = ["ActiveRecord", "Mongoid"] # Mongoid is default

  config.custom_styles do
    publisher "52x"
    my_custom_style "50x50"
  end
end
  • Attachment Magick is based on 960 Grid System (960.gs/)

Add to application.rb

config.middleware.insert 0, 'Rack::Cache', {
  :verbose     => true,
  :metastore   => URI.encode("file:#{Rails.root}/tmp/dragonfly/cache/meta"),
  :entitystore => URI.encode("file:#{Rails.root}/tmp/dragonfly/cache/body")
} # unless Rails.env.production?  ## uncomment this 'unless' in Rails 3.1,
                                  ## because it already inserts Rack::Cache in production

config.middleware.insert_after 'Rack::Cache', 'Dragonfly::Middleware', :images
