Я использую mysql в качестве базы данных и получаю django.db.utils.OperationalError: (1054, "Unknown column 'commons_smsmessages.sent_date' in 'field list'"), когда добавляю поле к уже существующей модели. Как это исправить?
Я пробовал python manage.py makemigrations, а также пытался удалить все файлы миграции и запустить python manage.py makemigrations, но, похоже, это не работает.
Этомодель, которую я пытаюсь обновить / добавить в поле:
class SMSMessages(models.Model):
sms_number_to = models.CharField(max_length=14)
sms_content = models.CharField(max_length=160)
sender_company = models.ForeignKey("SMSUser", on_delete=models.PROTECT, related_name="company_that_sent", limit_choices_to=1)
sent_date = models.DateTimeField(auto_now=True)
class Meta:
verbose_name_plural = "SMSMessages"
def __str__(self):
return self.sender_company
Поле, которое я пытаюсь добавить в модель, - sent_date. Но всякий раз, когда я запускаю python manage.py makemigrations, я получаю сообщение об ошибке

Я ожидал, что make-миграция python manage.py успешно запустится, обновит мою базу данных и добавит столбец в модель / таблицу.
