django_celery_beat - "нет такой таблицы: main.django_celery_beat_solarschedule__old" при обновлении "django_celery_beat_periodictask"

Question

Я использую django + сельдерей, при запуске django devserver я получаю исключение

django.db.utils.OperationalError: no such table: main.django_celery_beat_solarschedule__old

и callstack сообщает, что это произошло при выполнении вставки в таблицу django_celery_beat_periodictask

База данных sqlite3. Версия Python 3.5.6. Все миграции были применены и django_celery_beat был добавлен в настройки

Телефонный код:

def register_task(task, interval=DEFAULT_TASK_INTERVAL):
    logger.info("Registering periodic task %s with interval %s", task, interval)
    name = "Default {}".format(task)

    schedule, _ = IntervalSchedule.objects.update_or_create(
        every=interval, period=IntervalSchedule.SECONDS)
    PeriodicTask.objects.update_or_create(
        name=name, defaults={
            "interval": schedule,
            "task": task
        })

Answer 1

Проблема была в Джанго. Миграции были сломаны для нового sqlite. https://code.djangoproject.com/ticket/29182

Answer 2

Полагаю, вы не запустили migrate, и в результате эти таблицы не были созданы.

Run

python manage.py migrate

И убедитесь, что вы добавили его в INSTALLED_APPS

INSTALLED_APPS = (
    ...,
    'django_celery_beat',
)
