"《轻量级Django》是一本由Julia Elman和Mark Lavin合著的专业书籍，旨在帮助读者掌握在现代Web开发中利用Django框架构建高性能、高效且轻量级应用的方法。本书特别关注如何将Django与RESTful API、WebSockets和前端MVC框架Backbone.js集成，以支持复杂的客户端交互和实时特性。
书中的主要内容包括：
1. **模块化设计**：提倡将可重用的应用分解为小型服务，通过它们之间的通信来构建系统，实现组件化开发，降低复杂性。
2. **静态原型网站**：通过创建静态网站作为快速原型，为web应用和网站设计提供早期反馈，提高开发效率。
3. **Django与RESTful API**：学习如何使用`django-rest-framework`来构建RESTful API，这是后端服务的核心组成部分，为单页应用提供数据支持。
4. **Backbone.js集成**：了解如何结合Django与Backbone.js MVC框架，实现前后端分离，提高用户体验和开发灵活性。
5. **单页应用构建**：基于REST API，构建功能完整的单页Web应用，简化页面刷新，提升性能。
6. **实时通信**：介绍如何利用WebSockets技术与Tornado网络库，实现实时数据传输，增强应用程序的交互性。
7. **实践导向**：书中提供了丰富的代码示例，鼓励读者将所学应用于自己的项目中，确保理论与实践相结合。
《轻量级Django》对于希望超越传统应用开发模式，探索Django在单页应用后台的强大潜力的开发者来说，是一本极具价值的资源。它降低了开发门槛，让开发者更加专注于核心业务逻辑，而不被不必要的重量所束缚。
来自Django核心开发者Aymeric Augustin和Python开发者Barbara Shaurette的推荐，进一步证实了这本书在提升开发效率和降低入门难度方面的价值。通过阅读和实践本书，读者将能更好地理解和运用Django，为现代Web开发注入新的活力。"
Python Packages
The only Python package that is required before you start this book is Django. All of
the examples have been tested and written to work with Django 1.7. It is recommended
that you install with pip:
hostname $ pip install Django==1.7
As of August 2014, Django 1.7 was still in a release candidate phase.
If the preceding installation does not work, you can install the 1.7 pre-
release from the development branch with pip install https://
github.com/django/django/archive/stable/1.7.x.zip.
To read more about what is new in this version of Django, visit https://docs.djangopro
ject.com/en/dev/releases/1.7/. For additional installation instructions, you can also see
the Django guide on installation.
Additional packages will be installed throughout the chapters. Chapters 1, 2, and 3 are
each independent projects and can be treated as separate virtual environments, again
with Django being the only prerequisite. Chapters 4 through 8 comprise one large
project, and the same virtual environment should be used for those chapters.
Web Development
As Django is a web framework, this book assumes you have some basic knowledge of
HTML and CSS. The JavaScript examples are more in depth, and the expected level of
knowledge is detailed more in the following section. A basic understanding of the HTTP
protocol, in particular the usage and purpose of the various HTTP verbs (GET, POST,
PUT, DELETE, etc.), is helpful.
JavaScript
The later chapters in this book make heavy use of JavaScript. You should also be familiar
with writing JavaScript/jQuery. A developer experienced doing DOM manipulation and
making AJAX calls with jQuery should be able to follow the examples using Backbone.js.
If you are familiar with another client-side framework such as Angular.js, Ember.js, or
Knockout.js, you will be ahead of the game. This is not meant to be a definitive guide
on Backbone.js. If you are not familiar with working with JavaScript, and Backbone.js
MVC architecture in particular, here are some recommended O’Reilly titles for you to
