Chapter 3 creates the main page so that we have the initial view and a URL. You will learn how to create templates for both the main page and the user page.

Chapter 4 is where the application really starts to take shape as user management is implemented. Learn how to log users in and out, create a registration form and allow users to manage their own accounts by changing email or password details.

Chapter 5 explores how to manage your growing bank of content. Create tags, tag clouds, and a bookmark submission form all of which interact with your database. Security features also come into play as you learn how to restrict access to certain pages and protect against malicious input.

Chapter 6 enables you to enhance your application with AJAX and jQuery as users can now edit entries in place and do live searching. Data entry is also made easier with the introduction of auto-completion.

Chapter 7 shows you how to enable users to vote and comment on their bookmark entries.

Chapter 11 covers extending and deploying your application. You will also learn about advanced features including offering the site in multiple languages, managing the site during high traffic, and configuring the site for a production environment.

Chapter 12 takes a brief look at extra Django features that have not been covered elsewhere in the book. You will gain the knowledge required to further your application and build on the basic skills that you have learned throughout the book.

In Detail

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 leverage its power to design, develop, and deploy a fully-featured website. It will walk you through the creation of an example web application, with lots of code. Each chapter will add new features to the site, and show what parts of Django to work on to build these features.

This book has been specifically written for Python developers new to Django, and it's goal is to help you put together Django applications as quickly as possible. This book will give you clear, concise and, of course, practical guidance to take you from the basics of creating pages with Django through to learning the skills that will make you a Django developer to be reckoned with.

This book is a beginner's guide to design, develop, and deploy a fully-featured dynamic website using the features of Django.

Approach

Being a beginner's guide this book has a very simple and clear approach. It is a practical guide that will help you learn the features of Django and help you build a dynamic website using those features.

Who this book is for

This book is for web developers who want to see how to build a complete site with Web 2.0 features, using the power of a proven and popular development system, but do not necessarily want to learn how a complete framework functions in order to do this.

Basic knowledge of Python development is required for this book, but no knowledge of Django is expected.
