1. Introduction to the Course

Dive into the world of web APIs with Flask, starting with the basics. You'll learn what APIs and REST APIs are, how to set up your project, configure your environment, and establish a GitHub SSH connection. This foundational knowledge will set you up for success.

Project Description

Project Initialization

Environment Configuration and Dependency Management

Establish SSH Connection to GitHub

2. Database and Models

Explore the core of database handling with SQLAlchemy. You'll learn to create robust models and understand many-to-one, one-to-one, and many-to-many relationships. This section empowers you with the skills to structure complex databases for real-world applications.

SQLAlchemy Set Up

Many-to-One Relationship

One-to-One Relationship

Many-to-Many Relationship

3. Flask-Smorest and Schemas

Unveil the power of Flask-Smorest and Marshmallow for managing web APIs and data serialization. You'll delve into JSON, schema handling, and the intricacies of data representation and validation, paving the way for advanced API development.

4. Endpoints with Blueprints and MethodView

Master the art of creating and managing endpoints with Flask's Blueprints and MethodView. From setting up your first endpoints to exploring Flask-Migration and SQLite Studio, and utilizing tools like Postman and Insomnia, you'll craft scalable and maintainable web architectures.

Blueprints and MethodView Overview

Start with Blueprints and MethodViews

First Endpoint, Flask-Migration and SQLite Studio

Postman and Insomnia

User and Player Endpoints

5. Authentication with JWT

Secure your web APIs with JWT authentication. Learn to set up Flask-JWT-Extended, handle user registration, login, and logout processes, and implement permissions and security measures. By the end of this section, you'll be adept at protecting and testing your endpoints.

Flask-JWT-Extended Set Up

User Registration

Login Endpoint

Logout Endpoint

Testing New Endpoints

6. Deployment

Prepare your Flask project for deployment. This final leap covers the essentials: creating a requirements.txt, code formatting with Black and Flake8, and documenting your project with a README.md. You'll also master Git for version control and branch merging, readying you for a seamless project launch.

Login Endpoint

The class and method for login are similar to those for registration. Let's write it:

We filter users in the database by username and check if such a user exists and if the password verification for this user passes. If so, we create a JWT access token.

In this method, we return an access token generated using the create_access_token function imported from the flask_jwt_extended library. We add the user ID information to the JWT access token so that when a user returns the JWT to us, we will know which user it belongs to.

If a user with the given username does not exist or the password does not match what is in the table, we return an error.

1. Which HTTP method is used by the UserLogin class to authenticate users?

2. What information is included in the JWT access token generated by the UserLogin method?

Everything was clear?
