Pydantic convert underscores in keys to hyphen when exporting to json

Question

I have a class

class SampleModel(BaseModel):
    first_name: str
    last_name int

When I export it to json, I want to json to be

{
    "first-name": "john doe",
    "last-name": 1234
}

I was going to use aliases, but does pydantic have a config or an option to directly do this for all fields in a model?

Does this answer your question? [Is it possible to change the output alias in pydantic?](https://stackoverflow.com/questions/69306103/is-it-possible-to-change-the-output-alias-in-pydantic) — JacekK, Sep 27 '22 at 19:52

Pydantic has an Alias Generator which can be used.
