Equivalent of Pydantic __root__ attribute

[johnthagen]

I have a Serializer that I would like to contain some data directly without an attribute name. Pydantic has this feature using the __root__ special attribute:

• https://docs.pydantic.dev/usage/models/#custom-root-types

class Pets(BaseModel):
    __root__: List[str]

And example of this data would be:

{
    ["a", "b", "c"]
}

This can be very nice when you want to express (and then have an automatic OpenAPI description for) root types.

With DRF, as far as I've been able to find, this isn't possible and you would need to name that field. I've found some hacks, but nothing that seems declarative in a way that other tools, such as drf-spectacular could take ahold of:

Does DRF have an equivalent way to model this kind of data?
