Database issues caused by '@ computed_field'

[kuuuuy]

Reflex: 0.8.11
OS: windows 11
python: 3.12

I created the database model in the following way, But an error occurred, and I found that it was related to '@ computed_field', It seems to conflict with the '@ computed_field' feature

class Stock(rx.Model, table=True):
    __tablename__ = 'stock'
    id: int | None = Field(default=None, primary_key=True)
    timestamp: date
    code: str
    open: float
    high: float
    low: float
    close: float

    @computed_field
    def color(self) -> str:
        if self.close > self.open:
            return 'red'
        else:
            return 'green'
