Hi @jash.s. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The useOne hook is a React hook and it cannot be used inside a regular function or event handler like handlePinCodeChange. React hooks should be called at the top level of your React function components or custom hooks. They should not be called inside loops, conditions, or nested functions to follow the Rules of Hooks (https://reactjs.org/docs/hooks-rules.html). However, you can use the useOne hook at the top level of your component and use its returned data in your handlePinCodeChange function. Here is an example based on the code you provided:

import { useState } from "react";  
import { useOne, HttpError } from "@refinedev/core";  

const YourComponent = () => {
  const [value, setValue] = useState("");
  const { data, isLoading, isError } = useOne({
    resource: apiEndpoint.pincode,
    id: value,
  });

  const pincodeData = data?.data;

  const handlePinCodeChange = async (value) => {
    console.log(value);
    if (value.length >= 6) {
      setValue(value);
      if(pincodeData){
        const {country,pincode,city,state} = pincodeData;
        form.setFieldsValue({
          country,
          pincode,
          city,
          state,
        });
      }
    }
  };

  // rest of your component
};

import { useState } from "react";  
import { useOne, HttpError } from "@refinedev/core";  

const YourComponent = () => {
  const [value, setValue] = useState("");
  const { data, isLoading, isError } = useOne({
    resource: apiEndpoint.pincode,
    id: value,
  });

  const pincodeData = data?.data;

  const handlePinCodeChange = async (value) => {
    console.log(value);
    if (value.length >= 6) {
      setValue(value);
      if(pincodeData){
        const {country,pincode,city,state} = pincodeData;
        form.setFieldsValue({
          country,
          pincode,
          city,
          state,
        });
      }
    }
  };

  // rest of your component
};

In this example, whenever the value changes and it has a length of 6 or more, the useOne hook will trigger a new request to fetch the data related to the new value (source: useOne documentation (https://refine.dev/docs/core/hooks/data/use-one)). Please note that you need to handle loading and error states properly in your component. You can use isLoading and isError variables returned from useOne for this purpose. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

is there a mutate getOne or get call ? @kapa.ai

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the information provided in the extracts, there isn't a specific mutate function for getOne or get calls in Refine. The mutate function is typically used with hooks that modify data, such as useUpdate, useCreate, useDelete, etc. For fetching data, you would typically use hooks like useOne, useList, useMany, etc. These hooks return the data and some other properties but not a mutate function. You can refer to the Refine documentation on data hooks (https://refine.dev/docs/guides-concepts/data-fetching#data-hooks) for more information on how to use these hooks. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how to make a get call when updating a field in form , have used antd for useForm and Form @kapa.ai

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To make a GET call when updating a field in a form, you can use the useEffect hook from React. This hook allows you to perform side effects, such as data fetching, in function components. Here's an example of how you can use it with useForm from Ant Design:

import { useEffect } from "react";
import { useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

export const YourComponent: React.FC = () => {
  const { formProps } = useForm();

  useEffect(() => {
    // This function will be called whenever the form values change
    const handleFormChange = (changedValues: any, allValues: any) => {
      // You can make your GET call here
      // For example, you can use the useGet hook from Refine
      // const { data } = useGet({ resource: "yourResource", id: changedValues.yourField });
    };

    // Listen for form value changes
    formProps.form.watch(handleFormChange);

    // Cleanup
    return () => {
      formProps.form.unwatch(handleFormChange);
    };
  }, [formProps.form]);

  return (
    <Form {...formProps}>
      <Form.Item label="Your Field" name="yourField">
        <Input />
      </Form.Item>
      // Your other form items...
    </Form>
  );
};

import { useEffect } from "react";
import { useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

export const YourComponent: React.FC = () => {
  const { formProps } = useForm();

  useEffect(() => {
    // This function will be called whenever the form values change
    const handleFormChange = (changedValues: any, allValues: any) => {
      // You can make your GET call here
      // For example, you can use the useGet hook from Refine
      // const { data } = useGet({ resource: "yourResource", id: changedValues.yourField });
    };

    // Listen for form value changes
    formProps.form.watch(handleFormChange);

    // Cleanup
    return () => {
      formProps.form.unwatch(handleFormChange);
    };
  }, [formProps.form]);

  return (
    <Form {...formProps}>
      <Form.Item label="Your Field" name="yourField">
        <Input />
      </Form.Item>
      // Your other form items...
    </Form>
  );
};

In this example, the handleFormChange function will be called whenever the form values change. You can make your GET call inside this function. Please replace "yourResource" and "yourField" with your actual resource and field names. Please note that the useEffect hook is not mentioned in the provided extracts. This is a basic React hook and you can learn more about it in the React documentation (https://reactjs.org/docs/hooks-effect.html). Also, the useGet hook is not mentioned in the provided extracts. This is just an example of how you can make a GET call. You should replace it with your actual data fetching code. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how make a getList call inside a inner function ? @kapa.ai

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- React hooks, including getList, cannot be called inside regular JavaScript functions. They must be called at the top level of a React function component or inside custom hooks. This is a rule enforced by React to ensure hooks behave predictably. However, you can use the data returned by the getList hook (via useList or useInfiniteList) inside your function. Here's an example:

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

const YourComponent = () => {
  const { data, isLoading, isError } = useList({
    resource: "yourResource",
  });

  const handleSomeEvent = () => {
    // You can use the data here
    console.log(data);
  };

  // rest of your component
};

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

const YourComponent = () => {
  const { data, isLoading, isError } = useList({
    resource: "yourResource",
  });

  const handleSomeEvent = () => {
    // You can use the data here
    console.log(data);
  };

  // rest of your component
};

In this example, handleSomeEvent is a regular JavaScript function inside a React component. It can use the data returned by the useList hook. If you need to fetch new data when an event happens, you might need to use a state variable to trigger a change in the parameters passed to useList. This would cause useList to fetch new data. Please replace "yourResource" with your actual resource name. For more information, you can refer to the useList documentation (https://refine.dev/docs/data/hooks/use-list/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai On a button click i want to make a get call to getList

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To make a getList call on a button click, you can use a state variable to trigger the call. Here's an example:

import { useState } from "react";
import { useList } from "@refinedev/core";
import { Button } from "antd";

const YourComponent = () => {
  const [trigger, setTrigger] = useState(false);

  const { data, isLoading, isError } = useList({
    resource: "yourResource",
    filters: trigger ? [{ field: "yourField", operator: "eq", value: "yourValue" }] : [],
  });

  const handleClick = () => {
    setTrigger(true);
  };

  return (
    <div>
      <Button onClick={handleClick}>Fetch Data</Button>
      {/* Use your data here */}
    </div>
  );
};

import { useState } from "react";
import { useList } from "@refinedev/core";
import { Button } from "antd";

const YourComponent = () => {
  const [trigger, setTrigger] = useState(false);

  const { data, isLoading, isError } = useList({
    resource: "yourResource",
    filters: trigger ? [{ field: "yourField", operator: "eq", value: "yourValue" }] : [],
  });

  const handleClick = () => {
    setTrigger(true);
  };

  return (
    <div>
      <Button onClick={handleClick}>Fetch Data</Button>
      {/* Use your data here */}
    </div>
  );
};

In this example, the useList hook will make a getList call whenever the trigger state changes. Initially, trigger is false, so no filters are applied and no data is fetched. When you click the button, trigger is set to true, which changes the filters and causes useList to fetch new data. Please replace "yourResource", "yourField", and "yourValue" with your actual resource name, field name, and value. For more information, you can refer to the useList documentation (https://refine.dev/docs/data/hooks/use-list/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
