Using With Rails 3
==================
Setting up the quick way
------------------------
config/initializers/dragonfly.rb:
require 'dragonfly/rails/images'
Setting up the more explicit way
--------------------------------
You can do the above explicitly.
config/initializers/dragonfly.rb:
require 'dragonfly'
app = Dragonfly[:images]
app.configure_with(:imagemagick)
app.configure_with(:rails)
app.define_macro(ActiveRecord::Base, :image_accessor)
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
Gemfile
-------
gem 'dragonfly', '~>0.9.12'
gem 'rack-cache', :require => 'rack/cache'
Capistrano
----------
If using Capistrano with the above, you probably will want to keep the cache between deploys, so in deploy.rb:
namespace :dragonfly do
desc "Symlink the Rack::Cache files"
task :symlink, :roles => [:app] do
run "mkdir -p #{shared_path}/tmp/dragonfly && ln -nfs #{shared_path}/tmp/dragonfly #{release_path}/tmp/dragonfly"
end
end
after 'deploy:update_code', 'dragonfly:symlink'
Use it!
