Django 1.0 Website Development

Overview of this book

Django is a high-level Python web framework that was developed by a fast-moving online-news operation to meet the stringent twin challenges of newsroom deadlines and the needs of web developers. It is designed to promote rapid development and clean, pragmatic design and lets you build high-performing, elegant web applications rapidly. Django focuses on automating as much as possible and adhering to the DRY (Don't Repeat Yourself) principle, making it easier to build high-performance web applications faster, with less code. This book will show you how to assemble Django's features and take advantage of its power to design, develop, and deploy a fully-featured web site. It will walk you through the creation of an example web application, with lots of code examples. Specially revised for version 1.0 of Django, the book starts by introducing the main design concepts in Django. Next, it leads you through the process of installing Django on your system. After that, you will start right away on building your social bookmarking application using Django. Various Django 1.0 components and sub-frameworks will be explained during this process, and you will learn about them by example. In each chapter, you will build one or more of the features that are essential in Web 2.0 applications, like user management, tags, and AJAX. You will also learn about good software development practices, such as keeping your application secure, and automating testing with unit tests. By the end of the book, you will have built a fully functional real-life Web 2.0 application, and learned how to deploy it to a production server.

Fortunately, a technology called web feeds already existed for providing users with frequently updated content. The concept behind this technology is simple:

  • An XML document containing the latest updates is published on the web site. This document is called a web feed

  • Users can take advantage of this document by subscribing to it, using a specialized program called a feed reader or aggregator

  • This program polls the feed on a regular basis and notifies the user when updates are available

Web feeds became an efficient and easy solution for tracking updates, and the technology of feeds and aggregators quickly spread among web sites and users. These...
