执行同步
用于生成数据表
manage.py@DjangoOnlineFreshSupermarket > makemigrations
manage.py@DjangoOnlineFreshSupermarket > migrate
# 就开始报错了
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency users.0001_initial on database 'default'.
删除数据库中 除了auth_user的其他表，然后重新来一次
大概原因是因为admin的模型依赖了之前默认的user模型，且之前还在user中添加了admin用户，然后又使用了AbstractUser继承导致出错。
