Describe the bug

I have the following SQLAlchemy models:

from uuid import UUID, uuid4

from sqlalchemy import ForeignKey, String, inspect
from sqlalchemy.dialects.postgresql import UUID as PSQL_UUID
from sqlalchemy.orm import DeclarativeBase, Mapped, mapped_column


class Base(DeclarativeBase):
    pass


class Interlocutor(Base):
    __tablename__ = "interlocutors"
    __mapper_args__ = {"polymorphic_on": "type", "polymorphic_identity": "interlocutor"}

    # Base primary key
    uuid: Mapped[UUID] = mapped_column(
        PSQL_UUID(as_uuid=True),
        primary_key=True,
        default=uuid4,
    )
    type: Mapped[str] = mapped_column(String, nullable=False)


class AIAgent(Interlocutor):
    __tablename__ = "ai_agents"
    __mapper_args__ = {"polymorphic_identity": "ai_agent"}

    uuid: Mapped[UUID] = mapped_column(
        PSQL_UUID(as_uuid=True),
        ForeignKey("interlocutors.uuid"),
        primary_key=True,
        default=uuid4,
    )

class Token(BaseModel):
    __tablename__ = "tokens"

    key: Mapped[str] = mapped_column(String, nullable=False)
    agent_id: Mapped[UUID] = mapped_column(PSQLUUID(), ForeignKey("ai_agents.uuid"), nullable=False)

    agent: Mapped["AuthUser"] = relationship(back_populates="tokens")

Then I create a view for the Token table.

When trying to create a new token, it fails with the following error (see full traceback below):

Column('uuid', UUID(), ForeignKey('chats.interlocutors.uuid'), table=<auth_users>, primary_key=True, nullable=False, default=CallableColumnDefault(<function uuid4 at 0x12ee09d00>))

The guys from SQLAlchemy provided a solution to this bug: https://github.com/sqlalchemy/sqlalchemy/discussions/12157#discussioncomment-11464233

Steps to reproduce the bug

Take the code above, create a view for the Token table and try to create a new row for that table using the admin panel.

Expected behavior

No response

Actual behavior

Debugging material

Column('uuid', UUID(), ForeignKey('chats.interlocutors.uuid'), table=<auth_users>, primary_key=True, nullable=False, default=CallableColumnDefault(<function uuid4 at 0x12ee09d00>))
