How to build a registry from a simple OpenAPI document dict?

[meoyawn]

I'm trying to build a registry

self.registry = Registry().with_resources(
    (f"#/components/schemas/{k}", Resource.from_contents(v, referencing.jsonschema.DRAFT202012)
    for k, v in openapi["components"]["schemas"].items()
)

but then it fails during validation

jsonschema.Draft202012Validator(registry=registry, schema=schema).validate(dict)

with

self = Resource(contents={'oneOf': [{'type': 'object', 'properties': {'status': {'enum': [200]}, 'headers': {'type': 'object'...['mime', 'body']}]}}, 'required': ['status', 'headers', 'body']}]}, _specification=<Specification name='draft2020-12'>)
pointer = '/components/schemas/YtDlInfo'
resolver = Resolver(_base_uri='', _registry=<Registry (25 resources, 5 uncrawled)>)

    def pointer(self, pointer: str, resolver: Resolver[D]) -> Resolved[D]:
        """
        Resolve the given JSON pointer.

        Raises:

            `exceptions.PointerToNowhere`

                if the pointer points to a location not present in the document

        """
        if not pointer:
            return Resolved(contents=self.contents, resolver=resolver)

        contents = self.contents
        segments: list[int | str] = []
        for segment in unquote(pointer[1:]).split("/"):
            if isinstance(contents, Sequence):
                segment = int(segment)
            else:
                segment = segment.replace("~1", "/").replace("~0", "~")
            try:
>               contents = contents[segment]  # type: ignore[reportUnknownArgumentType]
E               KeyError: 'components'

how do I correctly build a registry from an OpenAPI dict? Docs don't mention this

Thanks

I haven't looked at this carefully but two things:

• Support specifically for the OpenAPI spec is/was planned for but not implemented yet, so it's possible the answer here depends on finishing that work
• You're tagging the resources with JSON Schema 2020-12, so you're getting behavior for JSON Schema 2020-12, where what you have isn't going to work
• The reason it won't work is that #/components/schemas/{k} means "look for a components/schemas/k key in this subschema" for each subschema you're looping over -- and that is (probably) incorrect -- you want # to be the parent OpenAPI spec document, as that's presumably the one with the components/schemas sub-properties. So maybe try only adding the parent document and then using $refs to yourSpecDocument#/components/schemas/foo, but whether that works exactly correctly or not depends on any differences in OpenAPI.

Support for OpenAPI would be greatly appreciated.
