Support oneOf when describing requestBody

[bobics]

Is your feature request related to a problem? Please describe.
I'd like a way to describe two request bodies to the same API path, but with somewhat different bodies. For example, say I have a /user path, and want to be able to create a regular user and a manager user, where the manager user has multiple other fields that need to be set.

Describe the solution you'd like
The OpenAPI 3.0 spec supports oneOf for requestBody -> content -> application/json -> schema, per the docs:

      requestBody:
        description: A JSON object containing pet information
        content:
          application/json:
            schema:
              oneOf:
                - $ref: '#/components/schemas/Cat'
                - $ref: '#/components/schemas/Dog'
                - $ref: '#/components/schemas/Hamster'

https://swagger.io/docs/specification/describing-request-body/

Right now if you use oneOf here, it doesn't show any of the requestBodies.

Describe alternatives you've considered
I'm also tried using multiple requestBody examples per this other ticket I created, but unfortunately that isn't supported either.

Hi there,

Any ETA for this feature?

Thanks :)

[MikeRalphson]

No ETA at the moment, I'm afraid. Pull requests would be very welcome!

[Flo354]

Thanks for your answer, I'll look if I can do something

Hi, do we have any ETA on this ? If not can I get a summary of what needs to be changed with possible code pointers where to look for inspiration ? I guess this could be similar to the request response examples right ? Any pitfalls ?

[MikeRalphson]

Generally unless an issue is tied to a milestone with a date on it, then there is no ETA. I'll try and take a look at what's (not) going on and either fix or write it up for someone else.

is there still progress on this topic? having no proper support on oneOf/allOf renders the openapi-generator unusable for many use cases

[MikeRalphson]

@manuelhartl do you mean openapi-generator? That's a completely separate project.
