Heroku прекомпиляции активы не удалось по железнодорожному 4 приложения

Я установилHeroku прекомпиляции активы не удалось по железнодорожному 4 приложения

config.assets.initialize_on_precompile = false

в application.rb. Активы были прекомпилирована успешно локально бегом

RAILS_ENV=production bundle exec rake assets:precompile

Хотя манифест-fingerprint.json (Rails 4.0 генерирует manifest.json вместо manifest.yml) не был обнаружен при нажатии на Heroku и Heroku попытался прекомпиляцию снова запустить. Тогда я получил ошибку как:

Кажется, ошибка была из-файла в Lib/student_module.rb, который требуется в конфигурации/инициализаторах/student_init.rb:

#lib/student_module.rb, the error pointed to this line： 
user_attributes = User.new.abttributes.keys 
#config/initializers/student_init.rb 
require 'student_module' 
ActiveRecord::Base.extend Student

ошибка может быть вызвана тем, что Heroku инициализирует приложение, которое включает подключение к базе данных. Но я не должен был видеть сообщения, как

rake aborted! 
could not connect to server: Connection refused 
Is the server running on host "127.0.0.1" and accepting 
TCP/IP connections on port 5432?

, потому что я установил config.assets.initialize_on_precompile ложь, а также перекомпилировать активы на местном уровне.

Любые предложения по этому вопросу? Спасибо!

Вам необходимо включить функцию лабораторных работ на пользовательском env-компиляции Heroku, которая дает приложению доступ к переменным среды во время компиляции.

heroku labs:enable user-env-compile -a myapp

вы знаете, почему это решает проблему? Это похоже на быстрое исправление, которое нарушает лучшие практики Heroku. – corbin

Да, это так - это означает, что сборка зависит от чего-то определенного вне кода, который определенно нарушает 12фактор. Проблема в том, что в вашем приложении есть код, который обращается к БД при инициализации, он ожидает, что БД будет там, и вызывает ошибку - для Gems/Frameworks это исключает возможность возникновения этого события. –
