In most projects I'm using an initializer to load all lib/*.rb files,
like:
config/initializers/requires.rb:
# auto-load all ruby files from RAILS_ROOT/lib/
Dir[File.join(RAILS_ROOT, 'lib', '*.rb')].each do |file|
require file
Note, if you have any files you do not want auto-loaded, you certainly
don't want to use that initializer :). Alternate option would be to
create a very simple plugin:
vender/plugins/acts_as_commentable/init.rb:
class ActiveRecord::Base
def self.acts_as_commentable
include Commentable
end
end
This should work as well.
