Overview of this book

Discover what makes Flask, the lightweight Python web framework, popular, as you delve into its modular design that enables the development of scalable web apps. With this practical guide, you'll explore modern solutions, recommended design patterns, and best practices for Flask web development. Updated to the latest version of Flask and Python, this third edition of the Flask Framework Cookbook moves away from the outdated libraries, updates content to incorporate new coding patterns, and introduces recipes for the latest tools. You'll explore different ways to integrate with GPT to build AI-ready Flask applications. The book starts with an exploration of Flask application configurations and then guides you through working with templates and understanding the ORM and view layers. You’ll also be able to write an admin interface and get to grips with testing using the factory pattern, debugging, and logging errors. Then you’ll discover different ways of using Flask to create, deploy, and manage microservices using AWS, GCP, and Kubernetes. Finally, you’ll gain insights into various deployment and post-deployment techniques for platforms such as Apache, Tornado, and Datadog. By the end of this book, you'll have acquired the knowledge necessary to write Flask applications that cater to a wide range of use cases in the best possible way and scale them using standard industry practices.

Using the Flask-Admin extension

Flask-Admin is an available extension that helps in the creation of admin interfaces for our application in a simpler and faster way. All the subsequent recipes in this chapter will focus on using and extending this extension.

Getting ready

First, we need to install the Flask-Admin extension:

$ pip install Flask-Admin

We will extend our application from the previous recipe and keep building on the same.

How to do it…

Adding a simple admin interface to any Flask application using the Flask-Admin extension is just a matter of a couple of statements.

Simply add the following lines to the application’s configuration in my_app/__init__.py:

from flask_admin import Admin
app = Flask(__name__)
# Add any other application configurations
admin = Admin(app)

You can also add your own views to this; this is as simple as adding a new class as a new view that inherits from the BaseView class, as shown in the following code block...
