In Rails 3

NOTE: This post now lives (and kept up to date) on my blog: http://hakunin.com/rails3-load-paths

If you add a dir directly under app/

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

If you add a dir under app/something/

To workaround this elasticsearch issue while it's not merged yet:

https://github.com/elasticsearch/cookbook-elasticsearch/pull/103


1. Paste everything in recipe.rb into your recipe, AFTER including elasticsearch recipe
2. Replace MY_COOKBOOK with your cookbook name
3. Put elasticsearch.init.erb to the templates/default/elasticsearch.init.erb of your cookbook

When you run your runlist with this in place, it will fix things and restart elasticsearch.
