Bug: UUIDBase ID Value Changed from UUID to Bytes about polyfactory

[guacs]

Thanks for reporting this @junhopark97! I am able to reproduce this. According to git bisect, it seems #502 broke something.

Actually, this may be due to something in advanced-alchemy because the following works:

from uuid import UUID

from sqlalchemy.orm import DeclarativeBase, Mapped, mapped_column

from polyfactory.factories.sqlalchemy_factory import SQLAlchemyFactory


class Base(DeclarativeBase):
    ...

class User(Base):
    __tablename__ = "users"

    id: Mapped[UUID] = mapped_column(primary_key=True)


class UserFactory(SQLAlchemyFactory[User]):
    pass

assert isinstance(UserFactory.build().id, UUID)

@cofin any ideas?

Looking here https://github.com/jolt-org/advanced-alchemy/blob/main/advanced_alchemy/types/guid.py#L38 it seems the mapped typed for UUID in advanced alchemy uses binary under the hood.

By my understanding, TypeEngine.impl.python_type would be the internal type passed to a particular dialect engine. I think should prioritise TypeEngine.python_type over TypeEngine.impl.python_type

Thanks @guacs, @adhtruong!
