我的变异更新工作正常,但我想过滤结果,结果只过滤页面刷新?
看看cache.writeQuery(),文档说得到查询和concat到那所以我想这就是为什么它不过滤。反正有问题吗?
这里是我的CreatePost组件的代码
import React from 'react';
import gql from "graphql-tag";
import { Mutation } from "react-apollo";
const GET_POSTS = gql`
{
allPosts(orderBy: createdAt_DESC) {
id
title
content
}
}
`;
const CREATE_POST = gql`
mutation createPost($title: String!, $content: String!){
createPost(title: $title, content: $content){
id
title
content
}
}
`;
const udpateCache = (cache, { data: { createPost } }) => {
const { allPosts } = cache.readQuery({ query: GET_POSTS });
cache.writeQuery({
query: GET_POSTS,
data: { allPosts: allPosts.concat([createPost]) }
})
}
const CreatePost = () => {
//vars for the input refs
let titleInput
let contentInput
return (
<Mutation
mutation={CREATE_POST}
update={udpateCache}
>
{createPost => ( //##form and onSubmit ##// ) }
</Mutation>
)
}
export default CreatePost
当您执行writeQuery时,还需要传入所使用的任何变量,以确保从缓存中收到相同的信息。
const udpateCache = (cache, { data: { createPost } }) => {
const { allPosts } = cache.readQuery({ query: GET_POSTS });
cache.writeQuery({
query: GET_POSTS,
data: { allPosts: allPosts.concat([createPost]) },
variables: { orderBy: /* input */ }
})
}
