Rails 2.3.5 on App Engine (DataMapper)¶ ↑

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.

See the TinyDS version also: gist.github.com/269075

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

Copy this script to ".git/hooks/post-checkout" in your repository and make it executable:

chmod +x .git/hooks/post-checkout

Tweak it at will. I'm refreshing the bundle and restarting the app server because the Gemfile is different on my "hosted" branch than on other branches.
