readOnly and writeOnly not respected with allOf

[machitgarha]

If you have something like this:

type: object
required: [id]
properties
  id:
    allOf:
      - $ref: "#/id"
      - readOnly: true

then not passing "id" through a write request (e.g. POST) is not possible.

I thought you could not extend reference in OpenAPI like this:

https://swagger.io/docs/specification/using-ref/

It says 'Any sibling elements of a $ref are ignored.'

[machitgarha]

@pjordaan, this is not a sibling. A sibling has to be on the same object, but in allOf, they are parts of two different array elements. You can see a valid example here:

https://swagger.io/docs/specification/data-models/oneof-anyof-allof-not/#allof

ah sorry I overlooked the - before readOnly.
