石墨烯中继中基于光标的分页

如何解决石墨烯中继中基于光标的分页

我正在尝试为基于游标的基本分页编写模式。但是我无法从集合中获取数据，因为架构和解析器之间的链接没有正确发生。我可以得到一个完整的应用示例或使用石墨烯中继的基于光标的分页的指南吗？

我尝试的模式：

class VehicleNode(graphene.Node):
     car = graphene.String()
     bike = graphene.String()
    
    class Meta:
        model = Vehicle
        interfaces = (graphene.relay.Node,)  
        fields = "__all__"

class VehicleConnection(graphene.relay.Connection):
    class Meta:
        node = VehicleNode

class VehicleSchema(graphene.ObjectType):
    vehicles =  graphene.relay.ConnectionField(VehicleConnection)

它的解析器：

class VehicleQueryResolver:

    def resolve_Vehicle(self,parent,info,**kwargs):
       return Vehicle.objects.all()

这就是我在主函数中定义架构和解析器的方式：

VehicleResolver = VehicleQueryResolver()
Vehicle = graphene.List(VehicleSchema,resolver = VehicleQueryResolver.resolve_Vehicle)

查询：

query{
  Vehicle {
    vehicles(first:2){
      pageInfo{
        hasNextPage
        hasPrevIoUsPage
        startCursor
        endCursor
      }
      edges{
        cursor
        node{
          id
          car
          bike
        }
      }
    }
  }
}
