Web Development with Django

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.

In Exercise 3.01, Implementing a Simple Function-Based View, we saw how to create a view, do the URL mapping, and display a message in the browser. But if you recall, we hardcoded the HTML message Welcome to Bookr! in the view function itself and returned an HttpResponse object, as follows:

message = f"<html><h1>Welcome to Bookr!</h1> "\
"<p>{Book.objects.count()} books and counting!</p></html>"
return HttpResponse(message)

Hardcoding of HTML inside Python modules is not a good practice, because as the content to be rendered in a web page increases, so does the amount of HTML code we need to write for it. Having a lot of HTML code among Python code can make the code hard to read and maintain in the long run.

For this reason, Django templates provide us with a better way to write and manage HTML templates. Django's templates not only work with static HTML content but also dynamic HTML templates.
