레일 응용 프로그램이 충돌 할 때 config.eager_load = 사실

Question

나는 성공적으로 내 로컬 시스템에 기반 응용 프로그램을 가지고 있지만, Heroku가 배포하거나 rails server -e production 수율로 실행하면

는

=> Rails 4.0.0 application starting in production on http://0.0.0.0:3000 
=> Run `rails server -h` for more startup options 
=> Ctrl-C to shutdown server

내 environment.rb에이

입니다

# Load the Rails application. 
require File.expand_path('../application', __FILE__) 

# Initialize the Rails application. 
OldManager::Application.initialize! 

내가을 전환하는 경우 registrations_controller.rb는

# controllers/users/registrations_controller.rb 
class Users::RegistrationsController < Devise::RegistrationsController 

before_filter :configure_permitted_parameters 

protected 

# my custom fields are :name 
devise_parameter_sanitizer.for(:sign_up) do |u| 
u.permit(:name, :major, :email, :password, :password_confirmation) 
end 
devise_parameter_sanitizer.for(:account_update) do |u| 
u.permit(:name, :email, :password, :password_confirmation, :current_password) 
end 

end 

입니다이 config.eager_load = false이고 내 config/environment/production.rb이면 성공적으로 서버를 시작하고 내 응용 프로그램을 사용할 수 있습니다. eager_load은 프로덕션 환경에 바람직한 기능이라고 가정합니다. 그렇지 않으면 기본적으로 활성화되지 않습니다. 그렇다면 eager_load을 사용하여 앱을 실행할 수 있도록하려면 어떻게해야합니까? 아니면 내 서버가 서버를 중단시키는 원인에 대해 자세히 알아 보려면 어떻게해야합니까? 이 파일을 찾으려면 다른 파일이 필요하면 알려주십시오.

레일 4 및 루비 2.0.0을 실행 중입니다.

어떤 조언을 주셔서 감사합니다!
