阿波罗客户端突变后,如何将react组件的道具传递给选项?

之后,如何将react组件的道具传递给选项 apollo-client 突变

我正在使用 react 具有 阿波罗客户 . 在一个组件中,我试图运行一个删除变异,之后我想从本地存储中删除该项,而不需要执行 refetchQueries . 为了做到这一点,我一直在使用 options.update 命令

为了更新存储,我需要尝试删除的对象的父ID。它在react组件中可用,我只需要找到一种方法将其传递给 选项。使现代化 作用

const { fundId } = this.props;
const variables = { documentId: document.id };
const options = { variables }

this.props.deleteFundDocument(options)
.then( response => console.log("Document successfully deleted", response) )
  .catch( e => console.log("Document not deleted", e) )

export default graphql(FundDocumentQL.deleteFundDocument, {name: 'deleteFundDocument', options: FundDocumentQLOptions.deleteFundDocument})
)(DocumentDisplay)

下面是我从FundDocumentQLPOptions中传递给选项的内容,您可以看到我从localStorage中获取fundId,这有点像黑客。我宁愿试着把它传下去。

const deleteFundDocument = {
  update: (proxy, {data: {deleteFundDocument}}) => {
    try {
      if (localStorage.getItem('documentViewerFundId')) {
        const fundId = localStorage.getItem('documentViewerFundId');
        let data = proxy.readQuery({query: FundDocumentQL.allFundDocuments, variables: {fundId: fundId}});
        console.log('data.allFundDocuments 1', data.allFundDocuments);
        // console.log('documentId', documentId);
        console.log('variables.documentId', variables.documentId);
        const newDocuments = data.allFundDocuments.filter( item => {
          return item.id !== deleteFundDocument.id;
        });
        console.log('newDocuments', newDocuments);
        data.allFundDocuments = [...newDocuments];
        console.log('data.allFundDocuments 2', data.allFundDocuments);
        proxy.writeQuery({query: FundDocumentQL.allFundDocuments, data, variables: {fundId: fundId}});
      }
    } catch (e) {
      console.log(e);
    }
  }
};

我在apollo客户端文档中看到了这个示例: https://www.apollographql.com/docs/react/basics/mutations.html#graphql-mutation-options-variables

export default graphql(gql`
  mutation ($foo: String!, $bar: String!) {
    ...
  }
`, {
  options: (props) => ({
    variables: {
      foo: props.foo,
      bar: props.bar,
    },
  }),
})(MyComponent);

我看到了这个答案: Apollo can't access queryVariables in update: after a mutation

在这里阅读另一个答案 Apollo can't access queryVariables in update: after a mutation

我意识到我可以通过 fundId 从…起 this.props 当我创建 options 突变前的对象。

const { fundId } = this.props;    
const variables = { documentId: document.id };
const options = { 
  variables: variables,
  update:  (proxy, { data: { deleteFundDocument } }) => FundDocumentQLOptions.deleteFundDocument(proxy, deleteFundDocument, fundId)}
this.props.deleteFundDocument(options)
.then( response => console.log('Document successfully deleted', response) )
.catch( e => console.log('Document not deleted', e) )


export default graphql(FundDocumentQL.deleteFundDocument, {name: 'deleteFundDocument'})(DocumentDisplay)

来自FundDocumentQOptions

const deleteFundDocument = (proxy, deleteFundDocument, fundId) => {
  try {
    let data = proxy.readQuery({query: FundDocumentQL.allFundDocuments, variables: {fundId: fundId}});
    // console.log('data.allFundDocuments 1', data.allFundDocuments);
    data.allFundDocuments = data.allFundDocuments.filter( item => {
      return item.id !== deleteFundDocument.id;
    });
    // console.log('data.allFundDocuments 2', data.allFundDocuments);
    proxy.writeQuery({query: FundDocumentQL.allFundDocuments, data, variables: {fundId: fundId}});
  } catch (e) {
    console.log(e);
  }
};
