저는 IDE RubyMine을 사용하여 웹 기반 Ruby 프로그램을 작성하고 있습니다.RubyMine을 사용하여 웹 기반 Ruby 프로그램 만들기
나는 classses의 몇 가지있다 :

1: Add module to a scheme
2: Remove module from a scheme
3: Query modules
4: Modify module
5: Register a student on a scheme

7: Register a student on a module
8: Remove a student from a module"

course_modules.rb: 파이어 폭스, 나는 오류 메시지를 표시하는 것 웹 페이지를 받고 있어요, 내 웹 페이지를 보려면 :
오류 메시지가 말한다 :
이SyntaxError in ApplicationController#main_menu
(Filepath)/application_controller.rb:1: class/module name must be CONSTANT
class application_controller < ActionController::Base
Rails.root: (Filepath)/CourseManagementSystem
사람이 왜 표시하는 웹 페이지를받지 못했습니다 알고 있나요 내 웹 응용 프로그램? 이 권리를 어떻게 넣을 수 있습니까?
