Overview of this book

Django is a framework designed to balance rapid web development with high performance. It handles high levels of user traffic and interaction, integrates with a variety of databases, and collects and processes data in real time. This book follows a task-based approach to guide you through developing with the Django 2.1 framework, starting with setting up and configuring Docker containers and a virtual environment for your project. You'll learn how to write reusable pieces of code for your models and manage database changes. You'll work with forms and views to enter and list data, applying practical examples using templates and JavaScript together for the optimum user experience. This cookbook helps you to adjust the built-in Django administration to fit your needs and sharpen security and performance to make your web applications as robust, scalable, and dependable as possible. You'll also explore integration with Django CMS, the popular content management suite. In the final chapters, you'll learn programming and debugging tricks and discover how collecting data from different sources and providing it to others in various formats can be a breeze. By the end of the book, you'll learn how to test and deploy projects to a remote dedicated server and scale your application to meet user demands.

Once you have created categories in your app, you need to display them hierarchically in a template. The easiest way to do this with MPTT trees, as described in the Creating hierarchical categories with django-mptt recipe, is to use the {% recursetree %} template tag from the django-mptt app. We will show you how to do that in this recipe.

Getting ready

Make sure that your movies app has the Category model created, as per the Creating hierarchical categories with django-mptt recipe, and some categories are entered in the database.
