Как правильно реорганизовать файл настроек в Django | Django Split Settings?

Здравствуйте, помогите пожалуйста разобраться.

Решил реорганизовать в своем проекте файл настроек с помощью приложение django-split-settings. Использую следующую структуру:

project_name/settings/ <- директория в которой обычно Django по умолчанию создает файл settings.py
    __init__.py
    components
        __init__.py
        common.py
        secret_key.py
        database.py
    environments
        __init__.py
        development.py
        production.py


P.S. Cледующий код не вызывает ошибки при запуске команды python manage.py runserver. Ошибка вылетает когда пользователь заходит на любую из страниц проекта. В настройках правильно указаны параметры базы данных. В чем может быть ошибка?
