Support for FastAPI pydantic response models about fhir.resources HOT 5 OPEN

Thanks! This kind of works, in that the code runs, but the response model is incorrect and it doesn't play nice with FastAPI's OpenAPI documentation generation:

• The OpenAPI doc generators can't parse the response model, and gives the message "Unknown Type: Practitioner"
• The response model contains a bunch of private fields:

{
  "fhir_comments": null,
  "id": null,
  "_id": null,
  "implicitRules": null,
  "_implicitRules": null,
  "language": null,
  "_language": null,
  "meta": null,
  "contained": null,
  "extension": null,
  "modifierExtension": null,
  "text": null,
  "active": null,
  "_active": null,
  "address": null,
  "birthDate": null,
  "_birthDate": null,
  "communication": null,
  "gender": null,
  "_gender": null,
  "identifier": null,
  "name": null,
  "photo": null,
  "qualification": null,
  "telecom": null,
  "resourceType": "Practitioner"
}

If improved FastAPI support is something you'd be open to adding to the library, I'm happy to work on a pull request to see if we can fix these issues.

@garry-jeromson you are welcome to make your pull requests. we are fully open to add any new feature.
Just keep in mind that the new feature should not make any new mandatory package dependency as well as not violating FHIR Resource specification.

I think we have support the FastAPI typing methodology.
try

from fastapi import APIRouter
from fhir.resources.practitioner import Practitioner
from fhir.resources.fhirtypes import PractitionerType

router = APIRouter()

@router.get(
    "/practitioner",
    response_model=PractitionerType,
)
def get_practitioner(
) -> Any:
    return Practitioner()

Let us know if you face any problem.

if we add this to here: https://github.com/nazrulworld/fhir.resources/blob/main/fhir/resources/fhirabstractmodel.py#L516
We can remove all the _ properties from showing up on the Schema for FastAPI Swagger.

@staticmethod
        def schema_extra(schema: Dict[str, Any], model: Type['FHIRAbstractModel']) -> None:
            current_schema = schema.get('properties', {})

            for key in list(current_schema.keys()):
                if "_" in key:
                    current_schema.pop(key)

My next question is.. how do we get the sub models to render in FastAPI? if we do something like this:
name: HumanName = Field( None, alias="name", title="A name associated with the patient", description="A name associated with the individual.", # if property is element of this resource. element_property=True, ) i.e. removing the typing.List[fhirtypes.HumanNameType] we are nearly there, you get both the HumanName added to the Schema, but it also plugs in the full contract into the name field as well. Which might be problematic for some of the larger resources.

I don't know if there is a way to keep HumanNameType and then like.. simply add the HumanName to the Schema somehow?

What's the status on FastAPI? Is there any inherit functionality for fastAPI in this repository or is there a 3rd party tool now?
