Rails Ruby on Rails

In 2.1.0, if ActiveRecord is disabled in config/environment.rb using e.g.

  config.frameworks -= [ :active_record ]

script/server fails to launch:

[test_new_rails_features]$ script/server
=> Booting Mongrel (use 'script/server webrick' to force WEBrick)
=> Rails 2.1.0 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000

The culprit is config/initializers/new_rails_defaults.rb, which should test to see if ActiveRecord is loaded.

Will create and submit a patch ASAP...
