Django是一个开源的Web应用框架,由Python写成,并于2005年7月在BSD许可证下发布。Django的主要目标是使得开发复杂的、数据库驱动的网站变得简单。Django采用MVC设计模式注重组件的重用性和“可插拔性”,敏捷开发和DRY法则(Don't Repeat Yourself)。在Django中Python被普遍使用,甚至包括配置文件和数据模型。本文介绍Django在Linux(Ubuntu 14.04.2) My SQL(5.5.43)环境下安装、配置的过程,包括安装、运行、添加应用的所有流程,最终建立一个可以从My SQL读取文章并显示的Django应用。文章面向刚接触Python/Django的初学者,所以安装过程都以默认环境为主,用pip可以简化安装过程。 首先下载Django,得到 show tables; ---------------------------- | Tables_in_dmyz | ---------------------------- | auth_group | auth_group_permissions | auth_permission | auth_user | auth_user_groups | auth_user_user_permissions | django_admin_log | django_content_type | django_migrations | django_session ---------------------------- 10 rows in set (0.00 sec) from urls import include, url from django.contrib import admin from .
