module EventMachine
  # A simple iterator for concurrent asynchronous work.
  #
  # Unlike ruby's built-in iterators, the end of the current iteration cycle is signaled manually,
  # instead of happening automatically after the yielded block finishes executing. For example:
  #
  #  (0..10).each{ |num| }
  #
  # becomes:

Rails 2.3.5 on App Engine (TinyDS)¶ ↑

Recently, Takeru Sasaki was able to patch the Rails 2.3.5 calls to rubygems, and now we have it working on App Engine. He also created a datastore adapter called TinyDS. I just created an integration plugin called Rails_TinyDS that provides certain ActiveRecord method calls for Rails 2.3.5 generated scaffold.

See the DataMapper version also: gist.github.com/268192

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
