How to post OneToOne field in django rest-framework using overwrite create method

问题

I am trying to override create method to make a post request but i am stuck, here is my code

class Order(models.Model):
    street_number = models.PositiveIntegerField(blank=True, null=True)
    street_name = models.CharField(max_length=250, null=True, blank=True)

class Seller(models.Model):
    order = models.OneToOneField(Order, on_delete=models.CASCADE, related_name='seller_order',blank=True, null=True)
    first_name = models.CharField(max_length=250, null=True, blank=True)
    last_name = models.CharField(max_length=250, null=True, blank=True)

class OrderSerializer(serializers.ModelSerializer):
    sellers = SellerSerializer()
    class Meta:
        model = Order
        fields = '__all__'

    def create(self, validated_data):
        order = Order.objects.create(**validated_data)
        seller_validated_data = validated_data.pop('sellers')
        if seller_validated_data:
            seller_obj = Seller.objects.create(order=order)
            seller_obj.first_name = seller_validated_data.get('first_name')
            seller_obj.middle_name = seller_validated_data.get('middle_name')
            seller_obj.last_name = seller_validated_data.get('last_name')
        order.save()
        return order
