Моя цель - подключиться к базе данных oracle и выполнить запрос, чтобы заполнить эти результаты на веб-странице. Но когда я пытаюсь запустить python manage.py migrate, я получаю ошибку ниже. Даже когда я использую опцию --fake-initial или --fake та же ошибка. Я не хочу создавать какие-либо таблицы. Я только что внес изменения в файл settings.py для подключения к базе данных oracle вместо sqlite.
