Building RESTful Python Web Services

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

Persisting the user that makes a request


We want to be able to list all the users and retrieve the details for a single user. We will create subclasses of the two following generic class views declared in rest_framework.generics:

  • ListAPIView: Implements the get method that retrieves a listing of a queryset

  • RetrieveAPIView: Implements the get method to retrieve a model instance

Go to the gamesapi/games folder and open the views.py file. Add the following code after the last line that declares the imports, before the declaration of the GameCategoryList class. The code file for the sample is included in the restful_python_chapter_03_04 folder:

from django.contrib.auth.models import User 
from games.serializers import UserSerializer 
from rest_framework import permissions 
from games.permissions import IsOwnerOrReadOnly 
 
 
class UserList(generics.ListAPIView): 
    queryset = User.objects.all() 
    serializer_class = UserSerializer 
    name = 'user-list' 
 
 
class UserDetail(generics.RetrieveAPIView...
