How to make useCustom hook invalidate resources like useUpdate

Is there a way to make a call to useCustom invalidate resources such as "list" similar to the way useUpdate does? Such that the call will automatically cause the components to re-render?

Hi @HypnoticMeat. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To make the useCustom hook invalidate resources similar to how useUpdate does, you can use the invalidateQueries method from the useQueryClient hook provided by the @tanstack/react-query library. This method allows you to manually invalidate specific queries, causing the components to re-render. Here's how you can achieve this: 1. Import the necessary hooks:

   import { useQueryClient } from "@tanstack/react-query";
   import { useCustom } from "@refinedev/core";

   import { useQueryClient } from "@tanstack/react-query";
   import { useCustom } from "@refinedev/core";

2. Use the useQueryClient hook to get the query client instance:

   const queryClient = useQueryClient();

   const queryClient = useQueryClient();

3. Invalidate the desired queries using the invalidateQueries method:

   queryClient.invalidateQueries(["custom-key"]);

   queryClient.invalidateQueries(["custom-key"]);

4. If you don't know the query key, you can use the queryOptions property of the useCustom hook:

   useCustom({
       queryOptions: {
           queryKey: ["custom-key"],
       },
   });

   useCustom({
       queryOptions: {
           queryKey: ["custom-key"],
       },
   });

Here is a complete example:

import { useQueryClient } from "@tanstack/react-query";
import { useCustom } from "@refinedev/core";

const MyComponent = () => {
    const queryClient = useQueryClient();

    // Invalidate the "list" state of the "posts" resource
    const invalidatePostsList = () => {
        queryClient.invalidateQueries(["posts", "list"]);
    };

    // Example usage of useCustom with queryOptions
    useCustom({
        queryOptions: {
            queryKey: ["custom-key"],
        },
    });

    return (
        <button onClick={invalidatePostsList}>
            Invalidate Posts List
        </button>
    );
};

import { useQueryClient } from "@tanstack/react-query";
import { useCustom } from "@refinedev/core";

const MyComponent = () => {
    const queryClient = useQueryClient();

    // Invalidate the "list" state of the "posts" resource
    const invalidatePostsList = () => {
        queryClient.invalidateQueries(["posts", "list"]);
    };

    // Example usage of useCustom with queryOptions
    useCustom({
        queryOptions: {
            queryKey: ["custom-key"],
        },
    });

    return (
        <button onClick={invalidatePostsList}>
            Invalidate Posts List
        </button>
    );
};

For more information, you can refer to the useCustom documentation (https://refine.dev/docs/data/hooks/use-custom#how-to-invalidate-the-custom-query). This approach allows you to manually control the invalidation of queries, similar to how useUpdate automatically invalidates queries after a mutation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
