Иногда эта ошибка появляется только в среде разработки. И на нескольких платформах. Установлен ли ruby ​​на "rbenv" или "rvm".

Пути для my_courses_controller.rb и всех других контроллеров верны и дважды проверены. Странно то, что как только приходит второй запрос, все работает. Производственная среда пока не является проблемой. Рельсы autoload_path не были расширены.

Пример кода структуры: 

module DashboardWidgets
  class WidgetsController < ::ApplicationController
    private

    def set_user
      # sets user and stuff...
    end
  end
end

module DashboardWidgets
  class MyCoursesController < WidgetsController
    include CustomView
    layout false

    def show
      authorize [:dashboard_widgets, :my_course]
      set_dashboard_widget
      set_user
      search = Searches::LmsSearch.new current_user.learning_course_ids_by_type.merge(search_params)
      @courses = search.search

      render_custom_view
    end

    ...

end

Мы искали распространенные ошибки «уже инициализированная постоянная X» и предупреждения «предыдущее определение X» в течение нескольких недель, и теперь я абсолютно не представляю, в чем еще проблема.
