model.update_or_create KeyError about tortoise-orm

[waketzheng]

For why it raises KeyError instead of TypeError with Python<3.12, see this: https://stackoverflow.com/questions/78427983/why-does-dictid-1-id-2-sometimes-raise-keyerror-id-instead-of-a

I got different errors with the following code snippet:

import uuid

from tortoise import Tortoise, fields, run_async
from tortoise.models import Model


class Faqs(Model):
    id = fields.UUIDField(pk=True)
    question = fields.TextField(null=True)


async def run():
    await Tortoise.init(db_url="sqlite://:memory:", modules={"models": ["__main__"]})
    await Tortoise.generate_schemas()

    faq, _ = await Faqs.get_or_create(id="6aadafff-e0b9-497b-aeb2-65498a35b6f5")
    # modify question
    faq.question = "q111234"
    # assign new id
    faq.id = uuid.uuid4()
    # update_or_create, KeyError
    new_faq, created = await Faqs.update_or_create(id=faq.id, defaults=dict(faq))
    print(dict(new_faq), created)


if __name__ == "__main__":
    run_async(run())

ERROR is:

After change the Python version to 3.10, got the KeyError:

Traceback (most recent call last):
  File "/home/wenping/github/tortoise-orm/tortoise/models.py", line 1079, in get_or_create
