python - pydantic.error_wrappers.ValidationError : 11 validation errors for For Trip type=value_error. 缺失

Question

我的 pydantic 模式出现了这个错误，但奇怪的是它正确地生成了对象，并将其发送到 SQLAlchemy 模型，然后它突然对模型中的所有元素抛出错误。

response -> id
  field required (type=value_error.missing)
response -> date
  field required (type=value_error.missing)
response -> time
  field required (type=value_error.missing)
response -> price
  field required (type=value_error.missing)
response -> distance
  field required (type=value_error.missing)
response -> origin_id
  field required (type=value_error.missing)
response -> destination_id
  field required (type=value_error.missing)
response -> driver_id
  field required (type=value_error.missing)
response -> passenger_id
  field required (type=value_error.missing)
response -> vehicle_id
  field required (type=value_error.missing)
response -> status
  field required (type=value_error.missing)

我必须说所有字段都应该有值。而且错误跟踪不引用我代码的任何部分，所以我什至不知道在哪里调试。我是 SQLAlchemy/pydantic 的菜鸟

部分代码

    id: int

    origin = db.query(models.PlaceDB).filter(models.PlaceDB.id == trip.origin_id).first()
    destination = db.query(models.PlaceDB).filter(models.PlaceDB.id == trip.destination_id).first()
    db_trip = TripDB(
        id=(trip.id or None),
        date=trip.date or None, time=trip.time or None, price=trip.price or None, 

    distance=trip.distance or None, 
            origin_id=trip.origin_id or None, destination_id=(trip.destination_id or None), status=trip.status or None, 
            driver_id=trip.driver_id or None, passenger_id=trip.passenger_id or None, vehicle_id=trip.vehicle_id or None, origin=origin, destination=destination)
    try:
        db.add(db_trip)
        db.commit()
        db.refresh(db_trip)
        return db_trip

    except:
        return "Somethig went wrong"

这似乎是 pydantic 模型上的一个错误，它也发生在我身上，我无法修复它，但实际上如果你只是跳过路由中的类型​​检查它工作正常
