Question

使用以下方法在docker-compose中执行migrate命令：

docker-compose run web python manage.py migrate

我收到以下错误：

#->docker-compose run web python manage.py migrate
/usr/local/lib/python3.5/site-packages/django/db/models/fields/subclassing.py:22: RemovedInDjango110Warning: SubfieldBase has been deprecated. Use Field.from_db_value instead.

TypeError: int() argument must be a string, a bytes-like object or a number, not 'datetime.datetime'

原因是什么？我是Django和Docker设置的新手。
