Пример авторизации и управление пользователями.
Пример авторизации и управление пользователями. Для локаольного развертывания требуется сделать следующие шаги.
Переименовать local_settings.py_orig в local_settings.py
Исправьте следующие строки
SECRET_KEY Укажите свой ключ безопасности
DEBUG Выберите включен или выключен дебаг
ALLOWED_HOSTS Укажите свои сетевые адреса
CORS_ORIGIN_WHITELIST Добавьте свой список
CSRF_TRUSTED_ORIGINS Добавьте свой список
DB_CONFIG_SQLL или DB_CONFIG_PSQL выбирете один из доступных способов хранения данных
DB_CONFIG_PSQL Укажите актуальные учётные данные
В проекте в основу взять Django 4.2 Это стабильная ветка на данный момент, в версии 5.0 есть ряд изменений которые требую существенных изменений в проекте.
