[REQUEST] Using oneOf, anyOf or AllOf with inline schemas

[kheraankit]

Is your feature request related to a problem? Please describe.

We want to leverage oneOf in some of our API responses. The way these seem to function is one needs to first define these schemas part of the openapi_specs config that is supplied via swagger_helper.rb. This doesn't seem to support the schemas that are defined inline within the spec or in some ruby files. It expects these schemas to be present as part of the config.openapi_specs = { openapi: '3.0.1', ... schemas: {} } .

      parameter name: :blog, in: :body, schema: {
          oneOf: [
            { '$ref' => '#/components/schemas/blog' },
            { '$ref' => '#/components/schemas/flexible_blog' }
          ]
        }

Describe the solution you'd like

Is there a way to use them in the following manner

      schema:  {
          oneOf: [
            { '$ref' =>  { type: :object, properties : { ... } }},
            { '$ref' => { type: :object, properties : { ... } }}
          ]
        }

@kheraankit I think the issue here is that the inline schemas must be provided without the $ref key:

schema:  {
          oneOf: [
            { type: :object, properties : { ... } },
            { type: :object, properties : { ... } }
          ]
        }
