Inheritance in SQLAlchemy (with Flask)
SQLAlchemy is an Object-relational mapping (ORM) made for the Python programming language. ORMs in theory allow programmers to abstract away SQL. In simple terms they allow us to interact with a database using purely Python (objects/functions). I will be using the flask-SQLAlchemy extension for my examples. Each table is referred to as a model, each model is simply just a python class and each attribute of that class becomes a column in an SQL table. The database is made up of multiple models. Just like with normal Python models can inherit from other models and share attributes with the parent model. This is very useful if you going to have models that will store similar types of data. ...
