Django 中的 projects 和 app

An app is a Web application that does something – e.g., a Weblog system, a database of public records or a small poll app. A project is a collection of configuration and apps for a particular website. A project can contain multiple apps. An app can be in multiple projects.

projects 就是环境，整个项目以及 Django 的基础配置，可以理解为就是 siteName

创建 Django App：python manage.py startapp polls

path()函数接收 4 个参数，route、view、kwargs、name
