阅读更多关于 Apollo boost - __typename in query prevent new mutation

问题 I have a problem in my meteor/react/apollo (with boost) project. When I query data from the server, it adds __typename to every object and subobject in my query but it my case it creates a major issue as I normally reuse these data to send them to other mutation. Now the other mutation tell me there is an error because the __typename field is not defined in my graphql schema.

Apollo（阿波罗）是携程框架部门研发的配置管理平台，能够集中化管理应用不同环境、不同集群的配置，配置修改后能够实时推送到应用端，并且具备规范的权限、流程治理等特性。服务端基于Spring Boot和Spring Cloud开发，打包后可以直接运行，不需要额外安装Tomcat等应用容器。Java客户端不依赖任何框架，能够运行于所有Java运行时环境，同时对Spring环境也有较好的支持。.Net客户端不依赖任何框架，能够运行于所有.Net运行时环境，而且已经支持.NET Core。官网： https://github.com/ctripcorp/apollo Wiki： https://github.com/ctripcorp/apollo/wiki （一切的集成方式和使用方法都在这里） Issues： https://github.com/ctripcorp/apollo/issues （如果期间有任何问题，请通过这里查找大部分解决方法）说明：官方提供了分布式部署方案，但是基于本地开发和调试上一般是单机部署的比较多。且提供的Quick Start方案跑不起来。所以下面将针对单机搭建上做详细的实践,用作开发环境。注意：如果是生产环境一定要使用分布式部署方案来做高可用集群。下载Release版本： https://github.com/ctripcorp/apollo

how to set many-to-many relation in graphql mutation?

阅读更多关于 how to set many-to-many relation in graphql mutation?

问题 I may be missing something, but can not find any information on Apollo docs about the way to set a many-to-many relation when creating a new entry. When the relation is one-to-many it is as simple as setting the ID of the one-side of the relationship in the many-side object. But let's pretend I am working with Books and Authors, how would I write a graphql query that creates a Book for one (or many?) Authors? 回答1: This should probably happen at the API layer on the GraphQL server (i.e. schema

Apollo mutate calling update four times for a single mutation

阅读更多关于 Apollo mutate calling update four times for a single mutation

问题 Every time I add a new item in my app, the mutation calls update() four times, for some reason. The first two are optimistic data, and in the second batch, one is optimistic and one is real data from the network. I can't make any sense of this. The new item being created shows up twice on the page. This is my mutation: mutation CreateTrack($name: String!, $trackNum: Int, $s3Key: String!) { createTrack(name: $name, trackNum: $trackNum, s3Key: $s3Key) { trackId name createdAt duration trackNum
