Answer 1

Kho lưu trữ cookie bí mật gần đây đã bị xóa trong Rails 4. Xem Changelog.

Để ứng dụng của bạn hoạt động trở lại, hãy thay thế dòng config.session_store :encrypted_cookie_store bằng config.session_store :cookie_store trong config/initializers/session_store.rb. Cửa hàng sẽ được mã hóa tự động.

Nếu không chắc chắn. Tạo một ứng dụng Rails 4 mới (rails new app_name --pre) và xem các trình khởi tạo.
