Я использую Джанго.

После запуска миграции управления Python БД создается нормально. Однако через некоторое время БД внезапно исчезает. Команда drop не существует в моем коде.

Мне любопытно, почему БД удалена. Все данные удалены. (БД, Коллекция, Поле)

Кто-нибудь знает причину?

Это мой код

ниже кода — приложение/модели

модель

from djongo import models

class RealTime(models.Model):
    _id = models.CharField(max_length=255, primary_key=True)
    site = models.CharField(max_length=125)
    title = models.CharField(max_length=255)
    url = models.URLField()
    create_time = models.DateTimeField()
    GPTAnswer = models.TextField()
    
    class Meta:
        db_table = 'realtimebest'

class Daily(models.Model):
    rank = models.IntegerField()
    title = models.CharField(max_length=255)
    url = models.URLField()
    create_time = models.DateTimeField()

Ниже приведен код схемы:

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' Может ли это быть проблемой?

Какую часть необходимо изменить, чтобы решить проблему полного исчезновения данных?

1. Часовой пояс = Ложь

Но Python manage migrate это нормально
