How to Use Schema with Path Parameter?

In the example below, I am trying to figure out how to use the ClientSchema to correctly document and validate ClientResource.get. Is this possible?

ma = flask_marshmallow.Marshmallow()

class ClientSchema(ma.SQLAlchemyAutoSchema):
    class Meta:
        model = Client
    clientId  = ma.auto_field(description='The ID of the client', 
                                            required=True,
                                            validate=validate.Range(min=1))
                                            )

@bp.route('/<int:clientId>')
class ClientResource(MethodView):

    def get(self, *args, **kwargs):
        pass

I did think that the parameter converters could be employed to solve this issue, but I’m not familiar with werkzeug so really don’t know how to do this.

My example above should do what you want.

I understand the will to centralize.

I’d choose my way other yours because sending clientId twice to the view func kinda sucks while my method only leaves a bit of documentation in the call to route which is not that bad.

Yours should work too.

I rely on werkzeug path parameter converters for the validation, and if I define a custom path parameter converter, I register it in flask-smorest to get automatic documentation as explained in https://flask-smorest.readthedocs.io/en/latest/openapi.html#register-custom-path-parameter-converters.
