Я только что переместил приложение Rails 5.2.2 на рабочий сервер, и у меня возникли проблемы с MongoDB, ни один из запросов не работает.Вот некоторая информация:
CentOS 7
Ruby 2.6.3
Rails (5.2.2)
Mongoid (7.0.2)
$ mongo --version
MongoDB shell version v4.0.9
git version: fc525e2d9b0e4bceff5c2201457e564362909765
OpenSSL version: OpenSSL 1.0.1e-fips 11 Feb 2013
allocator: tcmalloc
modules: none
build environment:
distmod: rhel70
distarch: x86_64
target_arch: x86_64
Проверка подлинности MongoDB включена, пользователь с соответствующими правами был создан, БД не пуста (была восстановлена из локальной копии), вот производственный раздел файла mongoid.yml:
production:
clients:
default:
database: mydb_production
hosts:
- localhost:27017
username: myuser
password: "mypass"
options:
auth_mech: :scram
auth_source: admin
Я продолжаю видеть эти topology отладочные сообщения в производственном журнале:
[rails_root] /log/production.log

При подключении к консоли любая попытка чтения или записи записей приводит к следующей ошибке:
$ rails c production
Running via Spring preloader in process 3131
Loading production environment (Rails 5.2.2)
2.6.3 :001 > User.first
Traceback (most recent call last):
1: from (irb):1
NoMethodError (undefined method `encode' for nil:NilClass)
Есть идеи, что здесь происходит?Подключаясь к БД либо через графический интерфейс удаленно, либо через командную строку mongo, я могу нормально читать коллекции, поэтому я предполагаю, что это проблема между рельсами и mongo, а не самой mongo.
EDIT
Полная трассировка стека ошибки, мне кажется, что mongoid не может аутентифицироваться с MongoDB, не знаю почему, хотя, я использую те же конфигурации, что и при подключении через GUI или командную строку ...
