React Admin/通过“ra-data-graphql”库构建数据提供者 - 自动注入的“raFetchType”参数未定义

如何解决React Admin/通过“ra-data-graphql”库构建数据提供者 - 自动注入的“raFetchType”参数未定义

我正在尝试通过 ra-data-graphql 创建一个 dataProvider，如 library's README 中所述，并且我成功地将内省响应传递给 buildQuery 方法，但是 {{1我的 raFetchType 方法中的 }} 参数始终未定义，并且应该发生的查询映射失败。似乎 buildQuery 应该由库自动填充，或者我（或文档）遗漏了一些东西。

在将 raFetchType 注入 buildCustomQuery 时是否需要提供一些额外的选项？

您所期待的： buildGraphQLProvider 已定义（我假设为“GET_LIST”、“GET_ONE”等之一）

发生了什么： raFetchType 中的 raFetchType 参数（在库的源代码中称为 buildQuery）始终未定义

相关代码：

aorFetchType

// App.tsx

const [dataProvider,setDataProvider] = useState<DataProvider>();
const cache = new InMemoryCache();
const link = createHttpLink({
  uri: // my graphql API URL
});

const client = new ApolloClient({
  cache: cache,link: link,});

useEffect(() => {
  buildGraphQLProvider({
    client: { client },buildQuery: buildCustomQuery,introspection: {
      schema,// JSON prevIoUsly fetched from my GraphQL API
      operationNames: introspectionoperationNames,// function that maps the 'Country' resource to the correct query name for 'GET_LIST'
      include: ['Country'],// just trying it out with a single Resource first
    },}).then((dataProvider: any) => {
    setDataProvider(dataProvider);
  })
},[]);
