Overview of this book

Do you want to develop reliable and secure applications that stand out from the crowd without spending hours on boilerplate code? You’ve made the right choice trusting the Django framework, and this book will tell you why. Often referred to as a “batteries included” web development framework, Django comes with all the core features needed to build a standalone application. Web Development with Django will take you through all the essential concepts and help you explore its power to build real-world applications using Python. Throughout the book, you’ll get the grips with the major features of Django by building a website called Bookr – a repository for book reviews. This end-to-end case study is split into a series of bitesize projects presented as exercises and activities, allowing you to challenge yourself in an enjoyable and attainable way. As you advance, you'll acquire various practical skills, including how to serve static files to add CSS, JavaScript, and images to your application, how to implement forms to accept user input, and how to manage sessions to ensure a reliable user experience. You’ll cover everyday tasks that are part of the development cycle of a real-world web application. By the end of this Django book, you'll have the skills and confidence to creatively develop and deploy your own projects.

Class-based views

Django provides different ways in which developers can write views for their applications. One way is to map a Python function to act as a view function to create FBVs. Another way of creating views is to use Python object instances (based on top of Python classes). These are known as CBVs. An important question that arises is, what is the need for a CBV when we can already create views using the FBV approach?

When creating FBVs, the idea is that, at times, we may be replicating the same logic again and again, for example, the processing of certain fields or logic for handling certain request types. Although it is completely possible to create logically separate functions that handle a particular piece of logic, the task becomes difficult to manage as the complexity of the application increases.

This is where CBVs come in handy, as they abstract away implementation of the common repetitive code that we need to write to handle certain tasks, such as the rendering...
