Building RESTful Python Web Services

By: Gaston C. Hillar

Overview of this book

Python is the language of choice for millions of developers worldwide, due to its gentle learning curve as well as its vast applications in day-to-day programming. It serves the purpose of building great web services in the RESTful architecture. This book will show you the best tools you can use to build your own web services. Learn how to develop RESTful APIs using the popular Python frameworks and all the necessary stacks with Python, Django, Flask, and Tornado, combined with related libraries and tools. We will dive deep into each of these frameworks to build various web services, and will provide use cases and best practices on when to use a particular framework to get the best results. We will show you everything required to successfully develop RESTful APIs with the four frameworks such as request handling, URL mapping, serialization, validation, authentication, authorization, versioning, ORMs, databases, custom code for models and views, and asynchronous callbacks. At the end of each framework, we will add authentication and security to the RESTful APIs and prepare tests for it. By the end of the book, you will have a deep understanding of the stacks needed to build RESTful web services.

Preface

Adding security-related data to the models


We will associate a game with a creator or owner. Only the authenticated users will be able to create new games. Only the creator of a game will be able to update it or delete it. All the requests that aren't authenticated will only have read-only access to games.

Open the games/models.py file and replace the code that declares the Game class with the following code. The line that changes is highlighted in the code listing. The code file for the sample is included in the restful_python_chapter_03_04 folder.

class Game(models.Model): 
    owner = models.ForeignKey( 
        'auth.User',  
        related_name='games', 
        on_delete=models.CASCADE) 
    created = models.DateTimeField(auto_now_add=True) 
    name = models.CharField(max_length=200, unique=True) 
    game_category = models.ForeignKey( 
        GameCategory,  
        related_name='games',  
        on_delete=models.CASCADE) 
    release_date = models.DateTimeField() 
    played =...
