我在这里尝试做的是调用一个类的构造函数。 但它给了我一个错误。 它是说：missing1 需要位置参数

Question

class Sensor(db.Model):

    id = db.Column(db.Integer, primary_key=True)
    temperature = db.Column(db.Float())
    date = db.Column(db.DateTime)

    def __init__(self, temperature, date=None):
        self.temperature = temperature
        if date is None:
            date = datetime.utcnow()
        self.date = date

class SensorSchema(ma.ModelSchema):
    class Meta:
        model = Sensor
