Camel case serialization/deserialization for Schema about django-ninja

[fletcheaston]

I've basically solved this myself without library additions, the solution isn't perfect but I'm pretty happy with it.

I'm using the pyhumps package for camel-casing my strings.

from ninja import Schema
from humps import camelize


def to_camel(string: str) -> str:
    return camelize(string)


class CamelCaseSchema(Schema):

    class Config:
        alias_generator = to_camel
        allow_population_by_field_name = True

    def dict(self, ignore_alias: bool = False, by_alias: bool = True, **kwargs) -> 'DictStrAny':
        if ignore_alias:
            return super().dict(by_alias=False, **kwargs)

        return super().dict(by_alias=True, **kwargs)

And then I just use CamelCaseSchema as a drop-in for Schema everywhere.

It's a little funky, and I'm ignoring the by_alias entirely (because Ninja seems to have its own mind about using aliases). The only time I don't want to use by_alias is when I'm directly serializing the object to a Django Model, then I have to use...

MyModel.objects.create(**myschema.dict(ignore_alias=True))

This method allows me to serialize directly to a Django Model and the schema shows up in the Swagger documentation correctly. I personally think adding this to the library would be beneficial. I'm happy to submit a PR and update the Ninja docs to highlight this use case @vitalik. If you reopen the issue, I can throw this and the docs together and submit a PR within a day or so.
