调研方向

Start by locating the oneOf and discriminator validation entry points in the Python library, then reproduce the issue with the provided schema and request. Trace how the discriminator mapping selects a schema and compare the current generic error with the requested property-specific validation error. Done means the mapped schema is validated and invalid requests receive useful errors.

描述

area/schema kind/enhancement

If a discriminator is set for a list of oneOf schemas only the matching schema should be validated against and therefore useful errors can be provided:

schema

requestBody:
  content:
    application/json:
      schema:
        oneOf:
          - $ref: '#/components/schemas/cat_type'
          - $ref: '#/components/schemas/dog_type'
        discriminator:
          propertyName: type
          mapping:
            cat: '#/components/schemas/cat_type'
            dog: '#/components/schemas/dog_type'

request

{'type': 'dog' ...}

If the request is invalid the validator raises: "Exactly one valid schema should be valid, None found."

But if there's a discriminator we know which schema to validate against and could provide a useful error message. Such as what property is missing or invalid.
