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.

Creating a database for testing


Now we will create the PostgreSQL database that we will use as a repository for our testing environment. Notice that the testing computer or server must have PostgreSQL 10.5 installed on it, as explained in the previous chapters for the development environment. I assume that you are running the tests on the same computer in which you worked with the previous examples.

Note

Remember to make sure that the PostgreSQL bin folder is included in the PATH environmental variable. You should be able to execute the psql command-line utility from your current Terminal, Command Prompt, or Windows PowerShell.

We will use the PostgreSQL command-line tools to create a new database named test_flask_notifications. If you already have a PostgreSQL database with this name, make sure that you use another name in all the commands and configurations. You can perform the same task with any PostgreSQL GUI tool. If you are developing on Linux, it is necessary to run the commands as the...
