假设我有一个Vehicle模型给定的资源：

class Vehicle(models):
    doors = models.Integerfield
    brand = models.CharField

从不同的主机，我发送PUT请求以使用requests包更新其中一个属性：

requests.put(remote_host + "/" + vehicle_id, data={"brand":"New Brand"})

注意：门没有更新。

现在在遥控器上，我想更新正在发送的任何属性。这将发生在views.py资源Vehicle中：

def update(self, request):
    vehicle_to_update = Vehicle.objects.get(pk=self.request.data["id"])

    # How do I know here, that it is only "brand" that is being updated?
    # Do I need to check for every possible property and see if a value was provided?
    vehicle_to_update.brand = self.request.data["brand"]
    vehicle_to_update.save()
