ModelChoiceFIeld Использование и что включать в набор запросов?

Я никак не могу понять, почему моя ModelChoiceField не работает, даже после просмотра документации django о ModelForm, которая сбила меня с толку, несмотря на то, что я успешно полагался на них на протяжении всего обучения. Ошибка в моем коде, вероятно, глупая, и я заранее извиняюсь за это.

Ошибка, которую я получаю на терминале при попытке сделать makemigrations:

строка 429, в getattr raise AttributeError(name) from None AttributeError: objects'
