Я занимаюсь обновлением нашего продукта с rails 4.1 до 5.2. Я зациклен на том, что кажется проблемой, связанной с конвейером активов. Когда я загружаю приложение в наш браузер, я вижу следующую ошибку в журнале сервера, и в приложении отсутствуют все стили и код javascript, которые у него обычно есть.
DEPRECATION WARNING: The asset application.js" is not present in the asset pipeline.Falling back to an asset that may be in the public folder.
This behavior is deprecated and will be removed.
To bypass the asset pipeline and preserve this behavior,
use the `skip_pipeline: true` option.
Когда я получаю файл index.html приложения, я вижу, что всем изображениям и URL-адресам javascript не хватает дайджеста отпечатков пальцев, который они должны иметь. Интересно, что у них есть тот же S3 assets_host, что и у нас, так что на самом деле они обрабатываются хелперами.
Для демонстрации у меня есть два сервера с одинаковой конфигурацией, но на одном работает 4.1, а на другом 5.2. В обоих случаях я использую S3 в качестве assets_host, и дайджест включен. Я выполнил следующие команды в своих консолях:
