内容简要介绍了如何使用 Django 实现一个数据库驱动的 Web 应用。 为了让您充分理解 Django 的工作原理，这份文档为您详细描述了相关的技术细节，不过这并不是 一份入门教程或者是参考文档（我们当然也为您准备了这些）。如果您想要马上开始一个项目，可以 从 实例教程（zh）开始入手，或者直接开始阅读详细的参考文档。 Django 无需数据库就可以使用，它提供了对象关系映射器（ORM）。通过此技术，你可以使用 。通过此技术，你可以使用 Python 代码来描述数据库结构。 数据模型语法提供了很多方法来描述你的数据，这解决了多年来在数据库模式中的难题。以下是一个 简明的例子： 1. # mysite/news/models.py 2. 3. from django.db import models 4. 5. class Reporter(models.Model): 6. full_name __unicode__ 18. return self.headline 然后，运行 Django 命令行工具来创建数据库表。 1. $ python manage.py migrate migrate 命令会查找所有可用的模型，如果数据库中没有与之对应的表，则会为其自动创建。 Django 也提供了其他更丰富的控制方式。 接下来，你就可以使用一套便捷而丰富的 Python

和 Element UI 前后 端原理论述  作者：M&T. 2 《51 测试天地》七十四 www.51testing.com 后端开发（Django+Rest Framework+MySQL）： Django 负责处理 HTTP 请求和响应，以及 URL 路由的配置。它接收来自前端的 HTTP 请求，并根据 URL 将请求分发给相应的视图函数进行处理。 Rest Framework 的扩展，用于快速构建 RESTful API 接口。通过 Rest Framework，可以定义 API 视图和序列化器，实现数据的序列化和反序列化，从而方便地 与前端进行数据交互。 MySQL 是一个关系型数据库，用于存储后端的数据。 前端开发（Vue+Element UI）： Vue 是一种现代的 JavaScript 框架，用于构建用户界面。Vue 提供了丰富的组件和模 块，可以帮助开发者构建交互式的单页面应用（SPA）。 com 二、搭建流程 2.1 后端搭建流程 安装相关包->创建工程->后端依赖（pipenv）创建虚拟环境->后端服务配置启动->后 端创建子应用->后端 Rest Framework->数据库配置 简要说明： 安装相关包：在开始之前，首先需要安装 Python 和 pip，然后安装 Django 等相关包， 可以使用 pip 命令来安装。 创建工程：使用 Django 的命令行工具创建
