Is there a way to convert key casing in responses?

[eboddington]

I'd like to have my Pydantic models defined in snake_case but have the API return JSON with camelCase fields.

In FastAPI, I can do the following:

def to_camel(string: str):
    # returns "string" converted to camelCase

class MyModel(BaseModel):
    foo_bar: str

    class Config:
        alias_generator = to_camel
        allow_population_by_field_name = True

And the resulting JSON will be {"fooBar": "x"}. This is similar to the way it's described in the Pydantic docs.

This doesn't work with flask-pydantic. Is there any way to achieve similar behaviour?

Hi,

please refer to #15 where I implemented the solution.

Model aliases for response models are added in newest version 0.4.0.

If you are not satisfied with solution or have another suggestion, please reopen this or create a new issue.
