How to serrialize models with root

from pydantic import BaseModel
from typing import List

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

pets = Pets(__root__=['dog', 'cat'])
print(pets.json())

result: {"__root__": ["dog", "cat"]}
How can I get ["dog","cat"]?

pets.__root__

[samuelcolvin]

Just for future reference "["dog","cat"]" is ambiguous, it could be a python object or a JSON string without the quotes, best to be clear what you're taking about.

I guess json() should be changed as per v1 to serialize m.__root__ if it's defined that would fundamentally change it's behaviour from dict() but I think makes sense.

Anyone else, thoughts?

what is the pydantic 2 version of this question? because root is gone

[will-e-yams]

@tommyjcarpenter , the v2 property is just .root instead of .__root__.
