Django is one of the most popular web frameworks in use today. With a few lines of code, you can rapidly build a functional and secure website that can scale to millions of users. This book attempts to share solutions to several common design problems faced by Django developers. Sometimes, there are several solutions but we often wonder whether there is a recommended approach.

Experienced developers frequently use certain idioms while deliberately avoiding certain others. This book is a collection of such patterns and insights. It is organized into chapters each covering a key area of the framework, such as Models, or an aspect of web development, such as Debugging. The focus is on building clean, modular, and more maintainable code. Every attempt has been made to present up-to-date information and use the latest versions. Django 1.

Python 3. Both, both of which have been used here. Superheroes are a constant theme throughout the book. Most of the code examples are about building SuperBook—a social network of superheroes. As a novel way to present the challenges of a web development project, an exciting fictional narrative has been woven into each chapter in the form of story boxes. Chapter 1, Django and Patterns , helps us understand Django better by telling us why it was created and how it has evolved over time.

Then, it introduces design patterns, its importance, and several popular pattern collections. Chapter 2, Application Design , guides us through the early stages of an application life cycle, such as gathering requirements and creating mockups.

We will also see how to break your project into modular apps through our running project—SuperBook. Chapter 3, Models , gives us insights into how models can be graphically represented, structured using several kinds of patterns, and later altered using migrations built into Django 1. Chapter 4, Views and URLs , shows us how function-based views evolved into class-based views with the powerful mixin concept, familiarizes us with useful view patterns, and teaches us how short and meaningful URLs are designed.

Chapter 5, Templates , walks us through the Django template language constructs explaining their design choices, suggests how to organize template files, introduces handy template patterns, and points to several ways in which Bootstrap can be integrated and customized.

Chapter 6, Admin Interface , shows us how to use Django's brilliant out-of-the box admin interface more effectively, and several ways to customize it, from enhancing the models to improving its default look and feel. Chapter 7, Forms , illustrates the often confusing forms workflow, different ways of rendering forms, how to improve a form's appearance using crispy forms and various applied form patterns.

Chapter 8, Dealing with Legacy Code , tackles the common issues with legacy Django projects, such as identifying the right version, locating the files, where to start reading a large codebase, and how to enhance legacy code by adding new functionality. Chapter 9, Testing and Debugging , gives us an overview of various testing and debugging tools and techniques, introduces test-driven development, mocking, logging, and debuggers.

Chapter 10, Security , familiarizes you with various web security threats and their countermeasures, and especially with how Django can protect you. Finally, a handy security checklist reminds you of commonly overlooked areas. Chapter 11, Production-ready , introduces a crash course in deploying a public-facing application beginning with choosing your web stack, understanding hosting options, and walking through a typical deployment process. We go into the details of monitoring and performance at this stage.

Appendix, Python 2 versus Python 3 , introduces Python 3 to Python 2 developers. Starting off by showing the most relevant differences, while working in Django, we then move on to the new modules and tools offered in Python 3.

You will just need a computer PC or Mac and Internet connectivity to start with. Then, ensure that the following are installed:. I recommend working on a Linux-based system such as Ubuntu or Arch Linux. Here is a full disclosure: I prefer command-line interfaces, Emacs, and eggs sunny-side up. Certain chapters might also require installing certain Python libraries or Django packages.

In most cases, they can be installed using pip as follows:. Hence, it is highly recommended that you first create a separate virtual environment, as mentioned in Chapter 2, Application Design. This book is aimed at developers who want insights into building highly maintainable websites using Django. It will help you gain a deeper understanding of the framework, but it will also familiarize you with several web development concepts.

It will be useful for beginners and experienced Django developers alike. You do not have to be an expert in Django or Python. No prior knowledge of patterns is expected for reading this book. More specifically, this book is not about the classic Gang of Four patterns, though they might get mentioned.

A lot of practical information here might not be unique to just Django, but to web development in general. By the end of this book, you should be a more efficient and pragmatic. Open navigation menu. Close suggestions Search Search. User Settings.
