Overview of this book

The HTML over WebSockets approach simplifies single-page application (SPA) development and lets you bypass learning a JavaScript rendering framework such as React, Vue, or Angular, moving the logic to Python. This web application development book provides you with all the Django tools you need to simplify your developments with real-time results. You’ll learn state-of-the-art WebSocket techniques to realize real-time applications with minimal reliance on JavaScript. This book will also show you how to create a project with Docker from the ground up, test it, and deploy it on a server. You’ll learn how to create a project, add Docker, and discover development libraries, Django channels, and bidirectional communication, and from then, on you’ll create real projects of all kinds using HTML over WebSockets as a chat app or a blog with real-time comments. In addition, you’ll modernize your development techniques by moving from using an SSR model to creating web pages using WebSockets over HTML. With Django, you’ll be able to create SPAs with professional real-time projects where the logic is in Python. By the end of this Django book, you’ll be able to build real-time applications, as well as gaining a solid understanding of WebSockets with Django.

Chapter 4: Working with the Database

This chapter does not aim to teach you how to interact with a database using Django or to create migrations—I assume you already have those minimal skills. This chapter instead will show you how to work with real situations where a Channels instance interacts recurrently with models.

Unless the application is only powered by external APIs, having a database is an elementary requirement in any modern web development. The needs can range from functionality as simple as storing plain text in an orderly fashion, to an authentication system, to managing a complex structure of connections between users. In other words, you must connect to a database if you want to build a practical project.

Fortunately, Django is compatible with the most popular relational databases: PostgreSQL, MariaDB, MySQL, Oracle, and SQLite. And if that’s not enough, we can also connect to other possibilities thanks to extensions created by the community: CockroachDB...
