Django多租户迁移提高了KeyError：“ Prune”

Question

因此，我已经在一个项目中工作了一段时间，并且根本没有真正改变模型，因此没有进行任何迁移。现在，我需要添加两个新字段并删除另一个通常，这通常应该很好。我正在使用django-tenants，所以我运行迁移的命令是./ manage.py migrate_schemas。 现在，每当我运行该操作时，我都会获得错误keyError：“ Prune”（下面的完整追溯），似乎是Django的内部代码。

现在，之后，我尝试重新恢复更改，因此没有新的迁移并再次运行Comnad，并遇到了同样的错误。我还认为可能在某个时候数据库变得“肮脏”，所以我尝试从头开始迁移一个干净的数据库，结果相同。迁移甚至没有开始。

有人遇到过类似的事情吗？

似乎版本不兼容。

如果要使用新的django，则必须修补django-tenants手动和

def add_arguments(self, parser):
    parser.add_argument(
        '--prune', action='store_true', dest='prune',
        help='Delete nonexistent migrations from the django_migrations table.',
    )

django-tenants/blob/fc4956067fb3a486ae04472374705298f3a47474f6/django_tenants / t查找 evarese 与prune >，因此您可以创建新的;）
