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.

Preface

Chapter 7. Voting and Commenting

The main idea behind our application is to provide easy ways for users to discover and share bookmarks. One way to achieve this is to allow users to recommend bookmarks to each other. Since the main page of our application is empty, apart from a welcome message, we will enable users to share bookmarks with other users by submitting their favorite bookmarks to the main page of the application. After that, we will let other users vote for the bookmarks that they like, and then create a page for the most popular bookmarks by votes. This set of features will provide a fresh list of interesting bookmarks selected by our community of users. In the second part of this chapter, we will enable commenting on bookmarks. It will let users share opinions and discuss the bookmarks that are posted on our site. This chapter brings many exciting features to our application, and you will learn several new Django features while working through it.
