AttributeError 'User' объект не имеет атрибута 'userStripe'

Question

Использование Stripe API для создания формы оформления кредитной карты на моем веб-сайте. Я пытаюсь проверить следующую строку в моей view.py проверки приложения.

print (request.user.userStripe.stripe_id)

Это может быть способ настройки моих пользователей. Я попытался импортировать модели из пользовательского приложения. Я просто не понимаю, почему он этого не видит.

У меня есть два приложения: пользователи и проверка

У меня следующая ошибка на странице отладки

Вы должны использовать название модели в нижнем регистре, print(request.user.userstripe.stripe_id). Лучше установить related_name в вашем OneToOneField, чтобы вы точно знали, как получить доступ к userStripe из user.

class userStripe(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name='user_stripe')
    ...

print(request.user.user_stripe.stripe_id)
