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

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
