Model.objects.create为模型的一个字段获取了意外的关键字参数

Question

我有模型订单和订单时间定位。订单与orderTimelocation具有一对多关系：

class Order(models.Model):

    customer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='customer')
    retailer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='retailer')
    date_publish = models.DateField()
    date_available = models.DateField()
    weight = models.DecimalField(decimal_places=2, max_digits=5)

class orderTimelocation(models.Model):
    order = models.ForeignKey(Order, on_delete=models.CASCADE, related_name='ordertimelocation'),
    longitude = models.DecimalField(decimal_places=8, max_digits=12)
    latitude = models.DecimalField(decimal_places=8, max_digits=12)
    

并尝试序列化订单模型，该模型应接收ordertimelocation的。为此，我使用了可写嵌套序列化程序，如DRF文档中所述

class OrderSerializer(serializers.ModelSerializer):
    ordertimelocation = orderTimelocationSerializer(many=True)

    class Meta:
        model = Order
        fields = ['customer', 'retailer', 'date_publish', 'date_available', 'weight', 'ordertimelocation']

    def create(self, validated_data):
        timelocations_data = validated_data.pop('ordertimelocation')
        order = Order.objects.create(**validated_data)
        for timelocation_data in timelocations_data:
           orderTimelocation.objects.create(order=order, **timelocation_data)
        return order

我认为我的代码与文档中的代码类似，但出现以下错误：
