How can I require libraries in your Rails directory from the console?

Question

I have a script called query.rb in my lib directory. I want to require it so I can run it from the Rails console. I wonder if this is possible. The script work fine from within the application, so I know it's well formed and functional.

For Rails 3+, use load "#{Rails.root}/lib/your_lib_file.rb" load works like require, but allows you to re-load files as you edit them (unlike require, which you cant run again). See https://stackoverflow.com/a/6361502/513739

For Rails 4+:

require "#{Rails.root}/lib/query"

It says "no such file to load." – picardo Jan 05 '11 at 22:34

what does `Dir.glob("#{RAILS_ROOT}/lib/*")` say (do that in the rails console) – cam Jan 05 '11 at 23:03
This would work too but it's require "#{RAILS_ROOT}/lib/query.rb" – cldwalker Jan 06 '11 at 00:55
