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.

The general workflow of using jQuery consists of two steps:

  1. Select an HTML element or a group of elements to work on.

  2. Apply a jQuery method to the selected group.

Element selectors

jQuery provides a simple approach to select elements. It works by passing a CSS selector string to a function called $. Here are some examples to illustrate the usage of this function:

  • If you want to select all anchor (<a>) elements on a page, you can use the function call $("a")

  • If you want to select anchor elements which have the .title CSS class, use $("a.title")

  • To select an element whose ID is #nav, you can use $("#nav")
