编写视图 设计模板 这只是冰山一角 Django 最初被设计用于具有快速开发需求的新闻类站点，目的是要实现简单快捷的网站开发。以下 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 - 8 - 本文档使用 书栈(BookStack.CN) 构建 当你的模型完成定义，Django 就会自动生成一个专业的生产级管理页面 - 一个可以让已认证用户 进行添加、更改和删除对象的 Web 站点。你只需简单的在 admin 站点上注册你的模型即可。 1. # mysite/news/models.py 2. 3. from django.db import models 4 应用的典型流程是：先建立数据模型，然后搭建管理站点，尽可能快的跑起来。那样 你的团队（或者客户）就可以向网站里填充数据了。后面我们会谈到如何展示这些数据。 简洁优雅的 URL 规划对于一个高质量 Web 应用来说至关重要。Django 推崇优美的 URL 设计， 所以不要把诸如 .php 和 .asp 之类的冗余的后缀放到 URL 里。 为了设计你自己的 URL，你需要创建一个叫做 URLconf

总体而言，这种前后端分离的开发模式有助于实现前后端开发的解耦，使得各自的 开发工作更加专注和高效。前端负责用户界面的呈现和交互，后端负责数据处理和业务 逻辑，通过 API 接口进行数据传输和交互，从而实现一个完整的 Web 应用。 3 《51 测试天地》七十四 www.51testing.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 测试天地》七十四 www.51testing.com 依赖包，这些依赖包通常存储在 package.json 文件中。 前端服务配置启动：在项目目录下执行 npm run serve 命令，启动前端开发服务器， 可以在浏览器中预览项目。 三、关键技术介绍 1、后端为什么要创建虚拟环境，创建虚拟环境可以达到什么效果？ 隔离项目依赖：通过创建后端虚拟环境，每个项目都拥有独立的 Python 解释器和包 等工具来管理项目的依赖，这样 可以确保项目在不同环境中安装相同的依赖版本，从而避免由于依赖版本不一致而引发 的错误。 提高项目可移植性：将项目的依赖放在虚拟环境中，可以使得项目在不同的计算机 或服务器上都能轻松地部署和运行，而不需要担心依赖问题。 简化依赖管理：虚拟环境可以将项目所需的依赖以及其版本信息保存在一个文件中 （例如 Pipfile.lock），这样可以方便地重现项目的开发环境，使得依赖的安装和管理更加
