使用中继在Django石墨烯中将要求设为False

Question

带中继的Django-Graphene要求获得一个对象需要ID，我想在Node上使required = False，因此我可以由登录用户而不是用户ID来获得节点

class Customer(models.Model):
    user = models.OneToOneField(User)

class CustomerNode(DjangoObjectType):
    class Meta:
        model = Customer
        interfaces = (graphene.relay.Node,)

    @classmethod
    @login_required
    def get_queryset(cls, queryset, info):  # This should work
        return queryset.get(user=info.context.user)

class Query(graphene.ObjectType):
    customer = graphene.relay.Node.Field(CustomerNode)
    all_customers = DjangoFilterConnectionField(CustomerNode)

query getCustomer {
  customer(id: "XXX") {  # I don't want to pass this parameter!
    id
  }
}

如果我不传递任何参数，这是错误：

"message": "Field \"customer\" argument \"id\" of type \"ID!\" is required but not provided."
