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 views

To recall, a view in Django is a piece of Python code that allows a request to be taken in, performs an action based on the request, and then returns a response to the user, hence forming an important part of our Django applications.

Inside Django, we have the option of building our views by following two different methodologies, one of which we have already seen in the preceding examples and is known as function-based views, while the other one, which we will be covering soon, is known as class-based views:

  • Function-based views (FBVs): FBVs inside Django are nothing more than generic Python functions that are supposed to take an HTTPRequest type object as their first positional parameter and return an HTTPResponse type object, which corresponds to the action the view wants to perform once the request is processed by it. In the preceding exercise, index() and greeting_view() were examples of FBVs.
  • Class-based views (CBVs): CBVs are views that closely adhere...
