Overview of this book

Python is the language of choice for millions of developers worldwide that builds great web services in RESTful architecture. This second edition of Hands-On RESTful Python Web Services will cover the best tools you can use to build engaging web services. This book shows you how to develop RESTful APIs using the most popular Python frameworks and all the necessary stacks with Python, combined with related libraries and tools. You’ll learn to incorporate all new features of Python 3.7, Flask 1.0.2, Django 2.1, Tornado 5.1, and also a new framework, Pyramid. As you advance through the chapters, you will get to grips with each of these frameworks to build various web services, and be shown use cases and best practices covering when to use a particular framework. You’ll then successfully develop RESTful APIs with all frameworks and understand how each framework processes HTTP requests and routes URLs. You’ll also discover best practices for validation, serialization, and deserialization. In the concluding chapters, you will take advantage of specific features available in certain frameworks such as integrated ORMs, built-in authorization and authentication, and work with asynchronous code. At the end of each framework, you will write tests for RESTful APIs and improve code coverage. By the end of the book, you will have gained a deep understanding of the stacks needed to build RESTful web services.

Designing a RESTful API to interact with a complex PostgreSQL 10.5 database


So far, our Django-based RESTful API performed CRUD operations on a single database table in an SQLite database. Now, we want to create a more complex RESTful API with Django REST Framework to interact with a complex database model that has to allow us to register player scores for playing games that are grouped into ESRB ratings. In our previous RESTful API, we used a string field to specify the ESRB rating for a game. In this case, we want to be able to easily retrieve all the games that have a specific ESRB rating, and therefore, we will have a relationship between a game and an ESRB rating.

We must be able to perform CRUD operations on different related resources and resource collections. The following table enumerates the resources and the class name we will create to represent the model with Django REST Framework:

Resources

Class name that represents the model

ESRB ratings
