Book Description:

Django 4 By Example is the 4th edition of the best-selling franchise that helps you build web apps. This book will walk you through the creation of real-world applications, solving common problems, and implementing best practices using a step-by-step approach.

You'll cover a wide range of web app development topics as you build four different apps:

• A blog application: Create data models, views, and URLs and implement an admin site for your blog. Create sitemaps and RSS feeds and implement a full-text search engine with PostgreSQL. A social website: Implement authentication with Facebook, Twitter, and Google. Create user profiles, image thumbnails, a bookmarklet, and an activity stream. Implement a user follower system and add infinite scroll pagination to your website. An e-commerce application: Build a product catalog, a shopping cart, and asynchronous tasks with Celery and RabbitMQ. Process payments with Stripe and manage payment notifications via webhooks. Build a product recommendation engine with Redis. Create PDF invoices and export orders to CSV.
• An e-learning platform: Create a content management system to manage polymorphic content. Cache content with Memcached and Redis. Build and consume a RESTful API. Implement a real-time chat using WebSockets with ASGI. Create a production environment using NGINX, uWSGI and Daphne with Docker Compose.

This is a practical book that will have you creating web apps quickly.

What You Will Learn:

• Learn Django essentials, including models, ORM, views, templates, URLs, forms, authentication, signals and middleware
• Implement different modules of the Django framework to solve specific problems
• Integrate third-party Django applications into your project
• Build asynchronous (ASGI) applications with Django
• Set up a production environment for your projects
• Easily create complex web applications to solve real use cases

Who this book is for:

This book is for readers with basic Python knowledge and programmers transitioning from other web frameworks who wish to learn Django by doing. If you already use Django or have in the past, and want to learn best practices and integrate other technologies to scale your applications, then this book is for you too. This book will help you master the most relevant areas of the framework by building practical projects from scratch. Some previous knowledge of HTML and JavaScript is assumed.
