Schema allOf generation does not follow Swagger spec

[MibbitTom]

What are the steps to reproduce this issue?

I want to use Orval to generate an API that uses inheritance. But, my subclass' fields are being generated as optional even though I have marked them as required.

1. Use Orval to generate models using the following Yaml:

openapi: 3.0.1
info:
  contact:
    email: xxx
    name: xxx
    url: xxx
  description: xxx
  title: xxx
  version: '0.1'
servers:
  - url: http://localhost:8080
    description: Generated server url
paths:
  /api/notifications/mine:
    get:
      operationId: getMyNotifications
      responses:
        '200':
          content:
            '*/*':
              schema:
                type: array
                items:
                  oneOf:
                    - $ref: '#/components/schemas/NewTicketNotification'
          description: OK
      summary: Get my notifications
      tags:
        - Notifications
components:
  schemas:
    NewTicketNotification:
      required:
        - ctime
        - id
        - ticketId
        - type
        - userId
      type: object
      allOf:
        - $ref: '#/components/schemas/Notification'
        - type: object
          properties:
            ticketId:
              type: integer
              format: int32
            userId:
              type: integer
              format: int32
    Notification:
      required:
        - ctime
        - id
        - type
      type: object
      properties:
        ctime:
          type: string
          format: date-time
        id:
          type: integer
          format: int32
        type:
          type: string
      discriminator:
        propertyName: type

What happens?

Orval generates the following:

export interface Notification {
  ctime: string;
  id: number;
  type: string;
}

export type NewTicketNotificationAllOf = {
  ticketId?: number;
  userId?: number;
};

export type NewTicketNotification = Notification & NewTicketNotificationAllOf;

What were you expecting to happen?

The fields in the subclass NewTicketNotificationAllOf should be required. E.g.

export type NewTicketNotificationAllOf = {
  ticketId: number;
  userId: number;
};

They actually are generated as required if I manually add required in the properties of the allOf. E.g.

NewTicketNotification:
      required:
        - ctime
        - id
        - ticketId
        - type
        - userId
      type: object
      allOf:
        - $ref: '#/components/schemas/Notification'
        - type: object
          required:
          - ticketId
          - userId
          properties:
            ticketId:
              type: integer
              format: int32
            userId:
              type: integer
              format: int32

But I shouldn't have to do that! NewTicketNotification already has ticketId declared as required. This should supersede the non-required property included in the allOf.

Any other comments?

Swagger's editor and codegen tool interpret the YAML correctly so I think I have interpreted the spec correctly! (See pictures)

I presume the parser needs a change to use the oneOf/allOf/anyOf key to make properties required (if needed) or leave them alone if they are already required.

I think this is similar to #861

[MibbitTom]

Sweet! Yes, that looks to be referring to the same issue.

Do you know if the maintainers are looking into that still? Pull request looks pretty dead...

(In case anyone else has the same issue, I'm just using input.override.transformer to manually remove the allOf properties for now.)

[melloware]

That PR is way out of date. Probably need a new Pr if you are interested .

Ditto on this as-well^^
