42.深入模型 第3点的时候，继续不下去了。

drop database if exists oa;
create database oa default charset utf8;

Read the tutorial section “42.深入模型”, especially point 3, and inspect the instructions around the SQL setup and python manage.py migrate. Reproduce the reported migration failure, then clarify where the database commands belong and document the dependency or environment requirements needed for the command to complete.
