Creating a Model Layer for Flask 2

A model layer is a common and useful abstraction in web development. This course will teach you how to implement a model layer within Flask.

Embedding SQL queries within the backend of a web application can make it hard to maintain and extend functionality. In this course, Creating a Model Layer for Flask, you’ll learn to implement a model layer using SQLAlchemy and avoid these issues. First, you’ll explore the setup of SQLAlchemy and how to replace existing SQL queries. Next, you’ll discover how to extend an application using the model layer. Finally, you’ll learn how to manage authorization on views for both interactive and automated users. When you’re finished with this course, you’ll have the skills and knowledge of Flask needed to refactor or extend a model layer.
