FastAPI + OpenAPI Integration

[rja172]

Hi all,

thanks for the package. It is really nice to have pydantic defined over pandas dataframe. I am able to successfully integrate pandera with fast-api but having trouble integrating with swagger. I want to example shown in swagger to use "record" format instead of index format i.e. I want input and output to look like this

[{"score": 0.8, "prediction": 1.0}, {"score": 0.0, "prediction": 0.0}]

Another option is to have schema_extra variable. But that raises AttributeError:

AttributeError: '<class 'pandera.checks.Check'>' object has no attribute 'schema_extra'. Make sure any custom checks have been registered using the extensions API.
