Overview of this book

<p>This project-based guide will give you a sound understanding of Django 2.0 through three full-featured applications. It starts off by building a basic IMDB clone and adding users who can register, vote on their favorite movies, and upload associated pictures. You will learn how to use the votes that your users have cast to build a list of the top 10 movies. This book will also take you through deploying your app into a production environment using Docker containers hosted on the server in Amazon's Electric Computing Cloud (EC2). </p><p> </p><p>Next, you're going to build a Stack Overflow clone wherein registered users can ask and answer questions. You will learn how to enable a user asking a question to accept answers and mark them as useful. You will also learn how to add search functionality to help users find questions by using ElasticSearch. You'll discover ways to apply the principles of 12 factor apps while deploying Django on the most popular web server, Apache, with mod_wsgi. Lastly, you'll build a clone of MailChimp so users can send and create emails, and deploy it using AWS. </p><p> </p><p>Get set to take your basic Python skills to the next level with this comprehensive guide! </p><p></p>

Summary

In this chapter, we covered how to use the Django REST framework to create an RESTful API for our Django project. We saw how the Django REST framework uses similar principles to Django forms and Django generic views. We also used some of the core classes in the Django REST framework, we used a ModelSerializer to build aSerializerbased on a Django models, and we used aListCreateAPIViewto create a view that can list and create Django models We used RetrieveUpdateDestroyAPIViewto manage a Django model instance based on its primary key.

Next, we'll deploy our code to the internet using Amazon Web Services.
