SQLAlchemy | One To Many Relationships

SQLAlchemy | One To Many Relationships. In this video, I walk through how to create one to many relationships between two models using SQLAlchemy. One-to-many relationships are one of the most common database relationships. If you want to learn how to use one-to-many relationships using SQLAlchemy, then this video is a great starting point. I walk through how to create database tables and the different ways to create a relationship between two models. I also explain how to configure delete behaviour using cascade.
