Django: FieldError: Невозможно преобразовать ключевое слово 'name' в поле. Варианты: Имя, id

Только начинаю работать с Django. Я следовал этому руководству:Django Tutorial Part 3: Using models, и я столкнулся с этой проблемой на связанном шаге

• python3 manage.py makemigrations
• python3 manage.py migrate

После выполнения второй команды появляется ошибка.

Полное сообщение об ошибке:
