在阿波罗客户端突变后，如何将反应组件的道具传递给选项？

Question

在apollo-client突变后，如何将反应组件的道具传递给选项？

我正在使用与apollo-client react 。 在一个组件中，我试图运行一个delete突变，此后我想从本地存储中删除该项目，而无需执行refetchQueries 。 为了做到这一点，我一直在使用options.update命令。

为了更新商店，我需要我要删除的对象的父ID。 它在react组件中可用，我只需要找到一种方法即可将其传递给options.update函数。

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)

这是我从FundDocumentQLOptions传递给选项的内容，因为您可以看到我从localStorage那里获得了FundId，这有点怪。 我宁愿尝试将其正确传递。

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此示例： 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);

在这里阅读其他答案Apollo无法访问update中的queryVariables：发生突变后

我意识到我可以在突变之前创建options对象时，将fundId的this.props传递给update函数。

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)

从FundDocumentQLOptions

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);
  }
};
