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.

Auto-completion of tags


The last AJAX enhancement that we are going to implement in this chapter is auto-completion of tags. The concept of auto-completion found its way into web applications when Google released their Suggest searching interface. Suggest works by displaying the most popular search queries below the search input field based on what the user has typed so far. It's also similar to how code editors in integrated development environments offer code-completion suggestions based on what you type. This feature saves time by letting the user type a few characters of the word they want and then select it from a list, without having to type it completely.

We will implement this feature by offering suggestions when the user enters tags while submitting a bookmark. But instead of writing this feature from scratch, we are going to use a jQuery plug-in to implement it. jQuery enjoys a large and continually growing list of plug-ins that provide a variety of features.
