ローカル システムで正常にビルドされたアプリがありますが、Heroku にデプロイするか、yield で実行すると、次のようになりrails server -e productionます。
=> 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

私のenvironment.rbは
# Load the Rails application.
require File.expand_path('../application', __FILE__)
# Initialize the Rails application.
OldManager::Application.initialize!
そして registrations_controller.rb は
# 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
に切り替えるconfig.eager_load = trueとconfig.eager_load = false、config/environment/production.rbサーバーを正常に起動してアプリケーションを使用できます。実稼働環境に望ましい機能だと思いeager_loadます。そうでない場合、デフォルトでは有効になりません。では、アプリをeager_load有効にして実行できるようにするにはどうすればよいでしょうか? また、サーバーがクラッシュする原因について詳しく知るにはどうすればよいでしょうか? これを理解するために他のファイルが必要な場合は、お知らせください。
Rails 4 と Ruby 2.0.0 を実行しています。
アドバイスをありがとう！
