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.

We have seen how we can optimize our code and make it more concise using class-based generic views. ViewSets and routers help us further simplify our code. As the name indicates, ViewSets are a set of views represented in a single class. For example, we used the AllBooks view to return a list of all books in the application and the BookDetail view to return the details of a single book. Using ViewSets, we could combine both these classes into a single class.

DRF also provides a class named ModelViewSet. This class not only combines the two views mentioned in the preceding discussion (list and detail) but also allows you to create, update, and delete model instances. The code needed to implement all this functionality could be as simple as specifying the serializer and queryset. For example, a view that allows you to manage all these actions for your user model could be defined as tersely as the following:

class UserViewSet(viewsets.ModelViewSet...
