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.

Django’s middleware refers to a variety of software components that intervene in this request/response process to integrate important functionalities such as security, session management, and authentication.

So, when we write a view in Django, we don’t have to explicitly set a series of important security features in the response header. These additions to the response object are automatically made by the SecurityMiddleware instance after the view returns its response. As middleware components wrap the view and perform a series of pre-processes on the request and post-processes on the response, the view is not cluttered with a lot of repetitive...
