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 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 上面的代码将 URL 的正则表达式映射到 views 里的回调函数。正则表达式通过括号来提取 URL 中的参数值。当一个用户请求页面时，Django 会顺序遍历这些匹配模式，直至模式和请求的 URL 成功匹配。（如果全部模式都无法匹配，Django 会返回一个404视图。）这个过程会在瞬间完成， 因为这些正则表达式在启动时就被编译了。 一旦其中一个正则表达式匹配成功，Django 就会导入并调用指定的视图——那是一个简单的 ），它们是可以被放在“/polls/”、 “/fun_polls/”、 “/content/polls/”、 或者其他任何路径，而应用仍然是可以运行的。 什么时候使用 include() 当你要包含其他 URL 匹配模式时，你应该一直使用 include()。 admin.site.urls 在这里是一个例外。 不符合你所想看到的？ 如果你看到的是 include(admin.iste.urls) 而不是 admin

HTTP 请求向后端发送数据请求，后端根据请求进行相应的数据处理，并 返回响应数据给前端。 前端接收到后端返回的数据，并根据数据更新页面展示，实现与用户的交互。 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。 安装依赖非常简单，只需要运行一个命令即可，而不需 要手动管理依赖的安装。 提供更友好的命令行界面：Pipenv 提供了一组易于使用的命令，使得包管理和虚拟 环境管理更加直观和简便。 支持开发模式：Pipenv 支持将项目的开发依赖和运行时依赖分开，这样可以减少项 目打包时的冗余依赖。 3、Django Rest Framework 介绍 Django Rest Framework（简称 小编通过两个简单的案例，进行介绍了Yaml在我们自动化测试过程中如何存储数据， 通过 Python 进行读取 Yaml 文件数据，以及在自动化测试过程中参数化的数据如何在 Yaml 文件中存储且如何通过运行参数化模式的自动化测试用例，文章知识点不是很多，但是 很容易进行掌握，主打的一个简单易懂，希望本篇文章对您有所帮助，感谢您的阅读。 拓展学习 [5] 人工智能深度学习全栈开发工程师 咨询：微信 atstudy-js
