A new version of openapi-SQLAlchemy has been release which adds support for $ref for columns. The package now supports openapi schemas such as the following:
components:
schemas:
Id:
type: integer
description: Unique identifier for the employee.
example: 0
Employee:
description: Person that works for a company.
type: object
properties:
id:
$ref: "#/components/schemas/Id"
name:
type: string
description: The name of the employee.
example: David Andersson.
If you are interested in how this was accomplished with decorators and recursive programming, the following article describes the implementation: Python Recursive Decorators.
