after using it config.action_controller.include_all_helpers = false
when trying to run any ApplicationController method like (testing)
class ApplicationController < ActionController::Base .. def checking debugger end
running in console sc => Debugger enabled Loading development environment (Rails 3.1.0.rc5) ruby-1.9.2-p290 :001 > checking NameError: undefined local variable or method `checking' for main:Object
what's new about it ... ? none of the ApplicationController can be run ...
