Question

我有一个数据库中的产品列表，想通过将一些过滤器参数作为变量传递给Query组件来查询产品来更新列表。

问题是，当我使用Query组件的refetch时，它会渲染包含在Query组件<Filter /> <ProductList />中的整个组件，而我丢失了这些组件的先前状态，导致重新折叠，如波纹管中的代码所示

  return (
    <Query
      query={GET_FILTER_QUERY}
      pollInterval={160000}
      variables={{ input: {} }}
    >
      {({ loading, error, data, refetch }) => {
        if (loading) return null
        if (data) {
          return (
            <Fragment>
              <Filter refetch={refetch} filterData={data} />
              <ProductList products={data} />
            </Fragment>
          )
        }
      }}
    </Query>
  )
}

在过滤器组件中提交我称为refetch的表单

onSubmit={async formValue => { refetch({ input: formValue }) }}

由于此问题而不是重新获取，我使用<ApolloConsumer>手动运行查询，但无法使用<ApolloConsumer>上的客户端更新现金

  const { brands, types, suppliers, tags } = props.filterData
  const { refetch } = props

  const mutators = {
    setSelector: (args, state, utils) => {
      utils.changeValue(state, args[0].key, () => args[0].value)
    }
  }

  return (
    <ApolloConsumer>
      {client => (
        <div className="row mt-5 mb-5">
          <FinalForm
            onSubmit={async formValue => {
              // refetch({ input: formValue })
              const { data } = await client.query({
                query: GET_FILTER_QUERY,
                variables: { input: formValue }
              })

              // const stores = client.readQuery({ query: GET_PRODUCTS_QUERY })

              return client.writeQuery({
                query: GET_FILTER_QUERY,
                data: {
                  getfilterProducts: data.getfilterProducts
                }
              })
              // console.log(stores)
            }}
            mutators={mutators}
            render={({ handleSubmit, form, values }) => (
              <form onSubmit={handleSubmit} noValidate>

                          }}

我通过使用查询组件updateQuery渲染道具功能解决了这个问题。

onSubmit={async formValue => {
              const { data } = await client.query({
                query: GET_FILTER_QUERY,
                variables: { input: formValue }
              })

              props.updateQuery((prev, { fetchMoreResult }) => {
                return { ...data }
              })
            }}

使用ApolloConsumer手动运行查询后如何更新现金？
