I have the following OpenAPI in components --> schema. In CreateBookDto, I want to refer only to the id property of my Person schema. Is this possible with OpenAPI? If yes, how? If not, is there any reason why this feature does not exist?
Person:
type: object
properties:
id:
type: number
description: ID of the person
username:
type: string
description: Username of the person
books:
description: All books of one person
type: array
items:
$ref: '#/components/schemas/Book'
CreateBookDto:
type: object
properties:
title:
type: string
description: The title of the book
person_id: <-- Here I want to reference to the id property of Person
type: number
description: The ID of the person
You can use a JSON pointer

person_id:
$ref: '#/components/schemas/Person/properties/id'
