FastAPI schema can not show the fields in parent odmantic.Model class

[SolardiaX]

Bug

# odmantic model
class User(odmantic.Model):
    username: str
    password: str

# model in fastapi for response
class CurrentUser(User):
    token: str


class LoginForm(pydantic.Model):
    username: str = pydantic.Field(description="Username")
    password: str = pydantic.Field(description="Password")


@router.post("/login", description="Method to login user",
             response_model=CurrentUser,
             response_model_exclude_none=True)
async def login(request: Request, db: AsyncEngine = Depends(get_engine), form = Body()) -> CurrentUser {
  ...
}

Current Behavior

The response model in FastAPI swagger for CurrentUser only has the token field, username and password in parent class is missing.

Expected behavior

The response model in FastAPI swagger for CurrentUser should contains username, password and token.

Additional context

I've got the same behavior. Here's my classes:

from odmantic import Field, Model

class CoreModel(Model):
    created_at: int = Field(
        default_factory=lambda: int(time.time()),
        description="Unix timestamp when the user was created",
    )
    updated_at: int = Field(
        default_factory=lambda: int(time.time()),
        description="Unix timestamp of the last update",
    )

class User(CoreModel):
    first_name: str
    last_name: str
