Overview of this book

Do you want to develop reliable and secure applications which stand out from the crowd, rather than spending hours on boilerplate code? Then the Django framework is where you should begin. 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 takes this philosophy and equips you with the knowledge and confidence to build real-world applications using Python. Starting with the essential concepts of Django, you'll cover its major features 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 that are presented as exercises and activities, allowing you to challenge yourself in an enjoyable and attainable way. As you progress, you'll learn 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. Throughout this book, you'll cover key daily tasks that are part of the development cycle of a real-world web application. By the end of this book, you'll have the skills and confidence to creatively tackle your own ambitious projects with Django.

Imagine a case where a developer is building an online event scheduling platform. On this platform, users can schedule events on their calendars as per their local time zone. Now, what if, on this platform, users can schedule events as expected, but due to a bug, the events are scheduled in an incorrect time zone? It is such issues that tend to drive many users away.

That is why a lot of companies spend a huge amount of money making sure that the applications they are building have undergone thorough testing. That way, they ensure that they do not release...
