Django-重建项目数据库

出于某些原因，我使用MYSQL命令DROP-database删除了我的数据库

我在MySQL数据库中使用Python3.6和Django 1.11

那么现在，我应该如何按照models.py重新构建我的数据库/表呢

我只是使用makemigrations，但我有一些错误，比如Django没有忘记任何表

manage.py makemigrations

File "/usr/local/lib/python3.6/site-packages/MySQLdb/connections.py", line 292, in query
_mysql.connection.query(self, query)
django.db.utils.ProgrammingError: (1146, "Table 'agora.start_games' doesn't exist")

仅供参考，“开始”是我django项目中唯一的应用程序。我知道这张桌子不存在，我只想把所有的都重建好

然后，我试着：

root@raspberrypi:/home/django-project/agora# python3.6 manage.py migrate --run-syncdb
