Example Code

class Club(SQLModel, table=True):  
    __tablename__ = "clubs"

    updated_at: datetime = Field(sa_type=DateTime, sa_column_kwargs={"server_default": utcnow()})
    id: Optional[int] = Field(nullable=True, index=True, unique=True)
    uid: str = Field(nullable=False, sa_type=String, primary_key=True, sa_column_kwargs={"autoincrement":False})
    name: Optional[str] = Field(default=None, nullable=True)

    members: List[Member] = Relationship(back_populates="club", sa_relationship_kwargs=dict(cascade="all"))

class Member(SQLModel, table=True):  # type: ignore
    __tablename__ = "members"
    id: int = Field(nullable=False, sa_type=Integer, primary_key=True, sa_column_kwargs={
        "autoincrement": False
    })
    club_uid: str = Field(nullable=False, foreign_key="clubs.uid", index=True)

    club: "Club" = Relationship(back_populates="members")

Description

We are trying to update to pydantic v2 (from v1) and latest versions of sqlmodel and sqlalchemy. We have two models connected by a relationship. We want to get a model as a dict along with its relationships (as keys of the dict too). We use club.model_dump(inlcude={'id', 'uid', 'name', 'members'}). In the past instead of .model_dump we used .dict() with the same parameters it worked. Now model_dump method does not work and does not return the relationships as keys of the dict. We have tried various options of the method but nothing did the trick.
Any help and interest in the issue is welcome!
Thank you in advance.
