refetch data

hi to fetch data I use

  const { data, isLoading, isError } = queryResult;
// OR
  const {
    tableQueryResult: {data, isLoading, isError},
  } = useTable();

  const { data, isLoading, isError } = queryResult;
// OR
  const {
    tableQueryResult: {data, isLoading, isError},
  } = useTable();

in case I did some changes and I want to refetch the data in same page (it will be the same if I call fetch function in normal framework) how I can do it ?

Hi @the_grateful. 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 manually refetch the data using the refetch function provided by the queryResult or tableQueryResult returned from the useTable or useForm hooks. Here's an example of how you can use the refetch function with useTable:

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

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

// Call refetch() whenever you want to fetch the data again
refetch();

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

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

// Call refetch() whenever you want to fetch the data again
refetch();

And here's an example with useForm:

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

// Call refetch() whenever you want to fetch the data again
refetch();

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

// Call refetch() whenever you want to fetch the data again
refetch();

In these examples, refetch() is used to manually trigger the API call. You can call this function wherever you need to refresh the data. Sources: - Discord support thread: How to re-run useDataGrid?

is there the same for queryResult ? @kapa.ai

kapa.ai•9mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, the queryResult object returned by hooks like useForm, useList, useShow, and useCustom also provides a refetch function that you can use to manually trigger a refetch of the data. Here's an example of how you can use the refetch function with useForm:

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

// Call refetch() whenever you want to fetch the data again
refetch();

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

// Call refetch() whenever you want to fetch the data again
refetch();

And here's an example with useList:

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

const { queryResult } = useList({ resource: "posts" });

// You can then use queryResult.refetch to manually refetch the data
queryResult.refetch();

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

const { queryResult } = useList({ resource: "posts" });

// You can then use queryResult.refetch to manually refetch the data
queryResult.refetch();

In these examples, refetch() is used to manually trigger the API call. You can call this function wherever you need to refresh the data.

@kapa.ai here:

  const {
    tableQueryResult: {data, isLoading, isError, refetch }
  } = useTable();

  const {
    tableQueryResult: {data, isLoading, isError, refetch }
  } = useTable();

when I call refetch, will isLoading be true ?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the information provided in the extracts, when you call refetch using the useTable hook in refine, the isLoading state does not automatically become true during the refetching process after invalidation or during re-validation of the cache. This behavior was specifically discussed in a GitHub issue where it was noted that the tableProps.loading (which corresponds to isLoading when destructured from tableQueryResult) remains false during refetching after data changes, such as after editing a record and saving changes. To accurately track the loading state during refetching, you might need to consider additional states provided by TanStack Query (formerly React Query), which refine uses under the hood. Specifically, isFetching or isRefetching could be used alongside isLoading to determine if a refetch operation is in progress. Here's an example based on the discussions:

const {
  tableQueryResult: { data, isLoading, isError, isFetching, isRefetching, refetch }
} = useTable();

// To determine if data is being loaded or refetched, you might use:
const realLoadingState = isLoading || isFetching || isRefetching;

const {
  tableQueryResult: { data, isLoading, isError, isFetching, isRefetching, refetch }
} = useTable();

// To determine if data is being loaded or refetched, you might use:
const realLoadingState = isLoading || isFetching || isRefetching;

This approach combines isLoading with isFetching and isRefetching to provide a more accurate loading state during various data fetching scenarios, including initial loads, pagination changes, and data refetching.

why data not updated agter refetch ?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Hmm, I don't know enough to give you a confident answer yet. For detailed guidance and troubleshooting on why data might not be updating after a refetch call with useTable in refine, I recommend consulting the official refine documentation and resources: - Refine Documentation (https://refine.dev/docs/) - Refine GitHub Issues (https://github.com/refinedev/refine/issues) for similar issues or to open a new one. These resources can provide specific insights and examples related to the behavior of useTable and its refetch functionality. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai may I have to get the updated data from the refetch result and not data ?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the extracts provided, there isn't direct information about handling the updated data directly from the refetch result when using useTable or similar hooks in refine. Typically, in refine (which leverages React Query for data fetching and state management), the pattern involves using the data destructured from the hook's return object, which gets automatically updated upon a successful refetch. However, if you're encountering issues where data does not seem to update after calling refetch, it's important to ensure that your component correctly re-renders upon the data update. The data variable should automatically reflect the latest state after refetch completes, assuming the fetch was successful and the component re-renders accordingly. In standard React Query usage, refetch returns a promise that resolves to the query's latest state, including the updated data. While the extracts don't specifically mention this pattern for refine, you could theoretically access the updated data directly from the refetch call like so:

refetch().then(({ data: updatedData }) => {
  // Use updatedData here
});

refetch().then(({ data: updatedData }) => {
  // Use updatedData here
});

However, this approach is not explicitly described in the provided extracts, and refine's typical usage patterns rely on the automatic updating of the data variable provided by the hook. If you're not seeing data update as expected, it might be worth reviewing the component's rendering logic or checking for any issues that could prevent a re-render. For detailed guidance and best practices specific to refine, including handling data updates after refetching, please refer to the official refine documentation (https://refine.dev/docs/) and resources. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai

  const {
    tableQueryResult: {data, isLoading, isError, isFetching, isRefetching, refetch }
  } = useTable();
    refetch().then(({ data: updatedData }) => {
      console.log(updatedData)
    });

  const {
    tableQueryResult: {data, isLoading, isError, isFetching, isRefetching, refetch }
  } = useTable();
    refetch().then(({ data: updatedData }) => {
      console.log(updatedData)
    });

the update data is the data I have to take how I can update the data after refetching ?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the information provided in the extracts, there isn't a direct mention of handling or updating data manually after a refetch operation within the context of using useTable in refine. In refine, and generally in React Query which refine builds upon, the data variable should automatically update to reflect the latest state after a refetch operation completes, without the need for manually setting the data from the refetch promise. In a typical use case with refine (and React Query), the data variable is reactively updated when the refetch function is called and completes successfully. This means that your component should automatically re-render with the updated data. Here's a simplified example of how it usually works:

const {
  tableQueryResult: { data, isLoading, isError, refetch }
} = useTable();

// When you call refetch, data is automatically updated upon successful completion
refetch();

const {
  tableQueryResult: { data, isLoading, isError, refetch }
} = useTable();

// When you call refetch, data is automatically updated upon successful completion
refetch();

In this pattern, you don't need to manually handle the updated data from the refetch promise. Instead, you rely on the reactive update of the data variable provided by the useTable hook. If data does not seem to update as expected, it's important to ensure that there are no issues with the component's re-rendering or with the fetch operation itself. If you find yourself in a situation where you need to manually handle the data from the refetch operation for some reason (which is not the standard approach in refine), you would typically need to manage the state yourself, outside of the standard useTable pattern. However, this approach is not covered in the provided extracts and would diverge from refine's intended usage patterns. For comprehensive guidance and best practices on using useTable and handling data fetching and updating in refine, please refer to the official refine documentation (https://refine.dev/docs/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai When I call refetch data is not updated upon successful completion what the reason may be ? may becuse I use old version ?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you're experiencing issues where data is not updated upon successful completion of a refetch operation when using useTable or similar hooks in refine, there could be several reasons for this behavior. While the provided extracts do not directly address this specific issue or its resolution, based on general knowledge of React Query and refine, here are some potential reasons and considerations: 1. Stale State or Props: Ensure that your component is correctly using the latest state or props. React's rendering optimizations might sometimes prevent a component from re-rendering if it doesn't detect a change in state or props. 2. Cache Configuration: React Query (used by refine for data fetching and caching) has configurations for cache time and stale time. If your query's cache time is too long, it might not be fetching fresh data as expected. However, the default behavior as mentioned in the extracts is to refetch data in the background if a query is reused within 5 minutes, which suggests that cache configuration might not be the issue unless explicitly changed. 3. Version Compatibility: You mentioned the possibility of using an old version. It's worth noting that both React Query and refine have seen significant updates over time. If you're using an older version, there might be bugs or differences in behavior that have been addressed in more recent releases. Ensure that you're using a version of refine that is compatible with your project requirements and has the latest features and fixes. 4. Error in Fetching: Verify that there are no errors during the fetch operation. Both isLoading and isError states can help diagnose if the fetch operation is completing successfully. An error in fetching could prevent the data from being updated as expected. 5. Manual Handling of Data: As mentioned previously, manually handling data from the refetch promise is not the standard approach in refine. Ensure that you're allowing refine to manage the data state automatically, as manual interventions could lead to unexpected behaviors. If you're still facing issues, consider the following steps: - Check the Console for Errors: Any errors during fetching or rendering might be logged to the console, providing clues to the issue. - Review refine and React Query Documentation: The official refine documentation (https://refine.dev/docs/) and React Query documentation can offer insights into correct usage patterns and potential pitfalls. - Update Your Dependencies: If you suspect a version issue, updating refine and its dependencies to the latest versions might resolve compatibility issues or bugs affecting your project. Without specific details on the version you're using or the exact nature of the fetch operation, these are general recommendations. For version-specific issues or bugs, consulting the refine GitHub repository or community forums might provide more targeted advice. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai why when I refetch the data not updated and the page not reload ?

  const {
    tableQueryResult: {data, isLoading, isError, isFetching, isRefetching, refetch }
  } = useTable();
  
  let orders = data?.data ?? [];
  console.log(data)

  if(isLoading || isFetching || isRefetching) return <center><CircularProgress disableShrink /></center>
  
  if(isError) { 
      mutateLogout() 
      navigate('/login') 
  }

  const handleClickOrderRemoved = async (itemId:any) => {
    await axios.delete(`${url}/Orders_History/${itemId}`,
    {withCredentials: true, responseType: 'json'}).then((res) => {
      setOrderToDelete(false);
      navigate("/Orders_History");
    })
    await refetch();
  }

  const {
    tableQueryResult: {data, isLoading, isError, isFetching, isRefetching, refetch }
  } = useTable();
  
  let orders = data?.data ?? [];
  console.log(data)

  if(isLoading || isFetching || isRefetching) return <center><CircularProgress disableShrink /></center>
  
  if(isError) { 
      mutateLogout() 
      navigate('/login') 
  }

  const handleClickOrderRemoved = async (itemId:any) => {
    await axios.delete(`${url}/Orders_History/${itemId}`,
    {withCredentials: true, responseType: 'json'}).then((res) => {
      setOrderToDelete(false);
      navigate("/Orders_History");
    })
    await refetch();
  }

Let me check the knowledge base for you. One moment! :books: ---------------------- The issue you're experiencing might be due to the asynchronous nature of the refetch function and the axios.delete request. In your handleClickOrderRemoved function, you're calling refetch immediately after the axios.delete request, but axios.delete returns a promise and it might not have completed before refetch is called. To ensure that refetch is called after the delete request has completed, you can move the refetch call into the then block of the axios.delete promise. Here's how you can modify your function:

const handleClickOrderRemoved = async (itemId:any) => {
  await axios.delete(`${url}/Orders_History/${itemId}`,
  {withCredentials: true, responseType: 'json'}).then(async (res) => {
    setOrderToDelete(false);
    navigate("/Orders_History");
    await refetch();
  })
}

const handleClickOrderRemoved = async (itemId:any) => {
  await axios.delete(`${url}/Orders_History/${itemId}`,
  {withCredentials: true, responseType: 'json'}).then(async (res) => {
    setOrderToDelete(false);
    navigate("/Orders_History");
    await refetch();
  })
}

In this modified version, refetch is called after the delete request has completed and the state updates have been made. If you're still facing issues, it might be worth checking if there are any errors during the fetch operation. You can use the error state from tableQueryResult to check for any errors during fetching. Also, ensure that your component is correctly using the latest state or props. React's rendering optimizations might sometimes prevent a component from re-rendering if it doesn't detect a change in state or props. Lastly, make sure you're using a compatible version of refine and its dependencies. If you're using an older version, there might be bugs or differences in behavior that have been addressed in more recent releases. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai is addint this work ?

 await refetch().then(({ data: updatedData }) => {
      orders = updatedData?.data ?? [];
    });

 await refetch().then(({ data: updatedData }) => {
      orders = updatedData?.data ?? [];
    });

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can use the refetch function to fetch the updated data and then update your orders variable with the new data. Here's how you can do it:

await refetch().then(({ data: updatedData }) => {
  orders = updatedData?.data ?? [];
});

await refetch().then(({ data: updatedData }) => {
  orders = updatedData?.data ?? [];
});

In this code, refetch is called and it returns a promise. When the promise resolves, it provides the updated data which you can then use to update your orders variable. However, please note that this will not trigger a re-render of your component because orders is not a state variable. If you want your component to re-render when orders changes, you should use the useState hook to manage its state. Here's an example:

const [orders, setOrders] = useState([]);

// ...

await refetch().then(({ data: updatedData }) => {
  setOrders(updatedData?.data ?? []);
});

const [orders, setOrders] = useState([]);

// ...

await refetch().then(({ data: updatedData }) => {
  setOrders(updatedData?.data ?? []);
});

In this code, setOrders is used to update the state of orders, which will trigger a re-render of your component. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
