Rails 2.3.5 on App Engine¶ ↑

We assumed Rails 2 would never work without rubygems, and we committed to gem bunlder for JRuby on App Engine, so we were waiting for Rails 3. Fortunately, Takeru Sasaki was able to patch the Rails 2.3.5 calls to rubygems, and now we have it working. Rails 2.3.5 currently spins up several seconds faster than Rails 3, and just a few seconds behind Sinatra.

Install the Development Environment¶ ↑

The gems for the development environment include a pre-release appengine-tools gem that provides a pre-release version of jruby-rack.

sudo gem install google-appengine
sudo gem install appengine-tools --pre

	# $ tweet Hi mom!
	#
	# Put this in ~/.bashrc or wherever.
	# If it doesn't work, make sure your ~/.netrc is right

	You must be using git and capistrano to deploy your app. Capistrano will place a file in your Rails.root named 'REVISION'. Tested with the following capistrano setting:

	set :scm, :git
	set :deploy_via, :remote_cache

	require 'rubygems'
	require 'sinatra'

	require 'fileutils'

	# upload with:
	# curl -v -F "data=@/path/to/filename" http://localhost:4567/user/filename

	post '/:name/:filename' do
	userdir = File.join("files", params[:name])

	set :default_stage, "canary"
