Python—Django配置问题：Unknown command: 'syncdb'

在配置完数据库mysite/settings.py后,

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

run python manage.py syncdb
命令参照 INSTALLED_APPS 设置，并在你的 settings.py 文件所配置的数据库中创建必要的数据库表。每创建一个数据库表你都会看到一条消息。
然而如果你安装的Django Version >= 1.9，那么会出现如下问题：

>>>python manage.py syncdb
Unknown command: 'syncdb'
Type 'manage.py help' for usage.

在stackoverflow上找到原因和解决方法：

syncdb is deprecated because of the migration system.
Now you can log your changes using makemigrations. This transforms your model changes into python code to make them deployable to another databases.
After you created the migrations you have to apply them: migrate.
So instead of using syncdb you should use makemigrations and then migrate.

>>>python manage.py migrate
Operations to perform:
  Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
  Applying contenttypes.0001_initial... OK
  Applying auth.0001_initial... OK
  Applying admin.0001_initial... OK
  Applying admin.0002_logentry_remove_auto_add... OK

通过sqlitebrower可以查看到数据库中的表。
