特别2的情况，奶奶的输出提示有错误把我整蒙了。。
每当创建一个Model以后需要更新。具体提示如下：
root@smart:~/mysite# python manage.py syncdb Operations to perform: Synchronize unmigrated apps: admin, contenttypes, auth, sessions Apply all migrations: (none) Synchronizing apps without migrations: Creating tables... Installing custom SQL... Installing indexes... Installed 0 object(s) from 0 fixture(s) Running migrations: No migrations needed. Your models have changes that are not yet reflected in a migration, and so won't be applied. Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
需要执行manage.py makemigrations.不然教程中的表格创建就不行了。。
执行结果:
root@smart:~/mysite# python manage.py makemigrations Migrations for 'polls': 0001_initial.py: - Create model Poll - Create model Choice
未免太恶心了。。。教程直接就没写。。让人自己摸索会死的亲。。。
最后完成了,可以接下去了。。坑爹..
