"app/controllers" added twice in load_paths

Hi,

I am trying to understand rails initialization process. While doing this I came across following code snippet in “https://github.com/rails/rails/blob/v2.3.8/railties/lib/initializer.rb” file

I am not getting why “app/controllers” have been added twice in load_paths. Is there any specific reason behind it?

def default_load_paths

paths =

Add the old mock paths only if the directories exists

paths.concat(Dir[“#{root_path}/test/mocks/#{environment}”]) if File.exists?(“#{root_path}/test/mocks/#{environment}”)

Add the app’s controller directory

paths.concat(Dir[“#{root_path}/app/controllers/”])

Followed by the standard includes.

paths.concat %w(

         app

         app/metal

         app/models

** app/controllers**

         app/helpers

         app/services

         lib

         vendor

    ).map { |dir| "#{root_path}/#{dir}" }.select { |dir| File.directory?(dir) }

paths.concat builtin_directories end

Thanks and Regards, Chirag Viradiya
