"Learning Django Web Development 是一本由 Sanjeev Jaiswal 和 Ratan Kumar 合著的书籍,专注于介绍如何使用 Django 框架进行Web开发。本书旨在引导初学者从概念到原型,全面理解Django在Web开发中的应用。" Django是一个用Python编写的开源Web框架,它遵循模型-视图-控制器(MVC)架构模式,旨在简化高效、可扩展和可维护的Web应用程序的创建。Django的核心特性包括: 1. **快速开发**:Django提供了一套强大的工具,如ORM(对象关系映射器),可以快速构建数据库驱动的应用程序,而无需编写大量的SQL代码。 2. **内置模板引擎**:Django的模板语言允许开发者将内容和呈现分离,创建动态HTML页面。它可以处理变量插入、条件语句、循环以及自定义过滤器和标签。 3. **URL路由系统**:Django的URL配置允许开发者创建清晰且可读的URL结构,将URL映射到相应的视图函数或类。 4. **表单处理**:Django提供了一种简单的方法来处理HTTP请求中的数据,包括表单的创建、验证和渲染。 5. **认证和权限**:Django内置了用户认证系统,包括用户注册、登录、密码管理以及基于角色的权限控制。 6. **安全**:Django默认配置了防止常见的Web攻击,如跨站脚本(XSS)、跨站请求伪造(CSRF)和SQL注入。 7. **性能优化**:Django支持缓存机制,可以缓存页面、查询结果或者自定义数据,提高网站的响应速度。 8. **多语言支持**:Django提供多语言支持,方便开发多语言的Web应用。 本书《Learning Django Web Development》将深入探讨这些核心概念,并指导读者: - 安装和配置Django环境 - 创建第一个Django项目和应用 - 设计和实现数据库模型 - 创建视图函数和类视图 - 使用模板系统构建动态页面 - 实现URL路由 - 处理表单和验证用户输入 - 用户认证和授权 - 部署Django应用到生产环境 通过学习这本书,读者不仅可以掌握Django的基本用法,还能了解Web开发的最佳实践,包括测试、调试和性能优化等。书中可能还会涵盖一些高级主题,如自定义中间件、管理命令、信号处理器以及如何扩展Django的内置功能。 《Learning Django Web Development》是初学者和有一定经验的Python开发者深入了解Django并提升Web开发技能的理想教程。它提供了从零开始构建Web应用的全面指导,使读者能够迅速掌握Django框架,从而将想法转化为实际的Web应用程序。

From idea to prototype, a learner's guide for web development with the Django application framework About This Book Build two real-life based projects, one based on SQL and other based on NoSQL Best practices to code, debug, and deploy the Django web application Easy to follow instructions and real world examples to build highly effective Django web application Who This Book Is For This book is for web developers who want to get started with Django for web development. Basic knowledge of Python programming is required but no knowledge of Django is expected. In Detail Django, written in Python, is a web application framework designed to build complex web applications quickly without any hassle. It loosely follows the MVC pattern and adheres to the Don't Repeat Yourself principle, which makes a database-driven application efficient and highly scalable, and is by far the most popular and mature Python web framework. This book is a manual that will help you build a simple yet effective Django web application. It starts by introducing Django, setting it up, and shows you how to code simple programs. You will then learn to build your first Twitter-like app. Later on, you will be introduced to Hashtags, AJAX to enhance the user interface, and tweets. You will then move on to create an administration interface, learn database connectivity, and use third-party libraries. Then you will learn to debug and deploy Django projects, and also get a glimpse of Django with AngularJS and Elasticsearch. By the end of the book, you will be able to leverage the Django framework to develop a fully functional web application with minimal effort. Table of Contents Chapter 1.
