What this book covers

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 1.7).

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.
