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.

Understanding the model-view-template paradigm

A common design pattern in application design is the Model View Controller (MVC), where the model of an application (its data) is displayed in one or more views, and a controller marshals interaction between the model and view. Django follows a different, yet similar, paradigm called the Model-View-Template (MVT).

Like MVC, MVT also uses models for storing data. However, with MVT, a view will query a model and then render it with a template. Usually, with MVC languages, all three components need to be developed with the same language. With MVT, the template can be in a different language. In the case of Django, models and views are written in Python, and the template is written in HTML. This means that a Python developer could work on the models and views, while a specialist HTML developer works on the HTML. We’ll first explain models, views, and templates in more detail and then look at some example scenarios where they are...
