is there a way to change the property names used for exception handlers?

I am wondering if something like this is possible: expose the property on a 400 response that is normally called status_code as e.g. status or statusCode.

For my own validators, I am experimenting with pydantic's alias_generator. I have a camel-case converter, and then place a Config on my models like so:

    class Config:
        alias_generator = to_camel
        allow_population_by_field_name = True

So far, this appears to do what I am expecting. It exposes the validation properties as camelCase, while allowing me to keep my pythonic snake_case properties internally. There are a few things I have to do to make this work:

1. Define the above mentioned config on all my input and output validators
2. In the controller, validate the response with the response validator, and then return the result of .dict(by_alias=True)
3. Define incoming parameters with the Parameter class so that I can specify the camel cased name of the property. Path string matchers in the route decorators then use the camel case version of the property name.

So far this looks good but then I have lingering things like the status_code on 400 responses or other public exceptions. From what I can tell, these don't really go through validation and the given properties are just coded into the HTTPException. So I'm not sure if there is really a straightforward way to change this.

Update. I guess point 3 above does not work like I thought. I suppose I would need to specify camel case path parameters. I don't see a way to specify a path parameter alias the way you can a query parameter. I was under the impression that the query property was overloaded for both, but I am seeing now that does not seem to be the case.

You can define a custom serializer on your response and modify the data there.
