How to prefetch a specific query with id?

Using invalidate just marks the query invalidated and the new data isn't being loaded when I open the component again. I want to force refetch the query i.e I want to refetch it.

Hi @ethix. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Refine, you can use the refetch function provided by the data-related hooks to manually refetch data. For example, if you are using the useShow hook to fetch a specific resource by its ID, you can use the refetch function as follows:

import { useShow } from "@refinedev/core";  

const { queryResult: { refetch } } = useShow();

import { useShow } from "@refinedev/core";  

const { queryResult: { refetch } } = useShow();

You can call refetch whenever you want to force a refetch of the data. This will bypass any caching and fetch fresh data from the server. If you want to invalidate a specific state of a resource with an ID, you can use the useInvalidate hook:

import { useInvalidate } from "@refinedev/core";  

const invalidate = useInvalidate();  

// To invalidate the state of a Posts with an id of 1  
invalidate({  
 resource: "posts",  
 invalidates: ["detail"],  
 id: 1,  
});

import { useInvalidate } from "@refinedev/core";  

const invalidate = useInvalidate();  

// To invalidate the state of a Posts with an id of 1  
invalidate({  
 resource: "posts",  
 invalidates: ["detail"],  
 id: 1,  
});

This will mark the specified state as invalidated. The next time you fetch this state, it will be fetched from the server instead of from the cache. Please note that invalidation does not trigger a refetch immediately. It only marks the data as outdated so that it will be refetched the next time it is needed.

@kapa.ai No, after a query is invalidated, it is refetched only when the component is mounted again. I want to force refetch the query, and not invalidate it

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In Refine, you can force a refetch of a specific query using the refetch function provided by the data-related hooks. For example, if you are using the useShow hook to fetch a specific resource by its ID, you can use the refetch function as follows:

import { useShow } from "@refinedev/core";  

const { queryResult: { refetch } } = useShow();

import { useShow } from "@refinedev/core";  

const { queryResult: { refetch } } = useShow();

You can call refetch whenever you want to force a refetch of the data. This will bypass any caching and fetch fresh data from the server. Similarly, you can use the refetch function with other hooks like useTable and useForm:

import { useTable, useForm } from "@refinedev/core";  

const { tableQueryResult: { refetch } } = useTable();  
const { queryResult: { refetch } } = useForm();

import { useTable, useForm } from "@refinedev/core";  

const { tableQueryResult: { refetch } } = useTable();  
const { queryResult: { refetch } } = useForm();

Please note that calling refetch will immediately trigger a network request to fetch the data, regardless of whether the data is currently being used or not.

@kapa.ai give me an example of how should I call the refetch function

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Sure, here's an example of how you can use the refetch function with the useShow hook in Refine:

import { useShow } from "@refinedev/core";  

const { queryResult: { data, refetch } } = useShow({
    resource: "posts",
    id: "1",
});

// Call refetch function when needed
refetch();

import { useShow } from "@refinedev/core";  

const { queryResult: { data, refetch } } = useShow({
    resource: "posts",
    id: "1",
});

// Call refetch function when needed
refetch();

In this example, useShow is used to fetch a specific post with the ID of "1". The refetch function is then used to manually refetch this data from the server. You can call refetch whenever you want to force a refetch of the data. This will bypass any caching and fetch fresh data from the server. Source: Refine FAQ: How can I refetch data?

@kapa.ai I tried refetching and logging the new data in console but still, the data is stale

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The refetch function in Refine returns a Promise that resolves to the new data. However, it doesn't immediately update the data variable in the component. The data variable will be updated on the next render after the refetch is complete. If you want to log the new data immediately after refetching, you can do so by awaiting the refetch function:

import { useShow } from "@refinedev/core";  

const { queryResult: { data, refetch } } = useShow({
    resource: "posts",
    id: "1",
});

// Call refetch function when needed
const newData = await refetch();
console.log(newData);

import { useShow } from "@refinedev/core";  

const { queryResult: { data, refetch } } = useShow({
    resource: "posts",
    id: "1",
});

// Call refetch function when needed
const newData = await refetch();
console.log(newData);

In this example, refetch is called and the returned Promise is awaited. The resolved value (which is the new data) is then logged to the console. Please note that you need to be inside an async function to use await. If you're not, you can use the then method of the Promise instead:

refetch().then(newData => {
    console.log(newData);
});

refetch().then(newData => {
    console.log(newData);
});

Remember that even though you can get the new data immediately with this method, the data variable in your component will still only be updated on the next render.

@kapa.ai This is exactly how I checked it.

const refetchQuery = async () => {
        console.log("refetch initiated");
        await refetch().then(
            ()=> console.log("refetch completed", variant_data)
        )
    }; 

    useEffect( () => {
        if(shallRefetch) refetchQuery();
    }, [shallRefetch]);

const refetchQuery = async () => {
        console.log("refetch initiated");
        await refetch().then(
            ()=> console.log("refetch completed", variant_data)
        )
    }; 

    useEffect( () => {
        if(shallRefetch) refetchQuery();
    }, [shallRefetch]);

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In your code, you're logging variant_data immediately after the refetch completes. However, variant_data won't be updated with the new data until the next render. This is why you're still seeing the old data in the console. If you want to log the new data immediately after the refetch, you should log the result of the refetch function instead:

const refetchQuery = async () => {
    console.log("refetch initiated");
    const newData = await refetch();
    console.log("refetch completed", newData);
}; 

useEffect( () => {
    if(shallRefetch) refetchQuery();
}, [shallRefetch]);

const refetchQuery = async () => {
    console.log("refetch initiated");
    const newData = await refetch();
    console.log("refetch completed", newData);
}; 

useEffect( () => {
    if(shallRefetch) refetchQuery();
}, [shallRefetch]);

In this updated code, refetch is called and the returned Promise is awaited. The resolved value (which is the new data) is then logged to the console. Remember that even though you can get the new data immediately with this method, the variant_data variable in your component will still only be updated on the next render.
