Hi @alfaz_muhammed. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Refine provides a hook called useForm that you can use to modify the form data before it is submitted to the API. When you use the useForm hook with action: "edit", it fetches the record data according to the id with useOne and returns the queryResult for you to fill the form. After the form is submitted, it updates the record with useUpdate. Here is an example of how to use useForm with action: "edit":

import { useForm } from "@refinedev/react-hook-form";  
  
const PostEditPage: React.FC = () => {  
 const {  
 refineCore: { onFinish, formLoading },  
 register,  
 handleSubmit,  
 formState: { errors },  
 } = useForm();  
  
 return (  
 <form onSubmit={handleSubmit(onFinish)}>  
 <label>Title: </label>  
 <input {...register("title", { required: true })} />  
 {errors.title && <span>This field is required</span>}  
 <br />  
 <label>Content: </label>  
 <br />  
 <label>Status: </label>  
 <select {...register("status")}>  
 <option value="published">published</option>  
 <option value="draft">draft</option>  
 <option value="rejected">rejected</option>  
 </select>  
 <br />  
 <textarea  
 {...register("content", { required: true })}  
 rows={10}  
 cols={50}  
 />  
 {errors.content && <span>This field is required</span>}  
 <br />  
 <input type="submit" value="Submit" />  
 {formLoading && <p>Loading</p>}  
 </form>  
 );  
};

import { useForm } from "@refinedev/react-hook-form";  
  
const PostEditPage: React.FC = () => {  
 const {  
 refineCore: { onFinish, formLoading },  
 register,  
 handleSubmit,  
 formState: { errors },  
 } = useForm();  
  
 return (  
 <form onSubmit={handleSubmit(onFinish)}>  
 <label>Title: </label>  
 <input {...register("title", { required: true })} />  
 {errors.title && <span>This field is required</span>}  
 <br />  
 <label>Content: </label>  
 <br />  
 <label>Status: </label>  
 <select {...register("status")}>  
 <option value="published">published</option>  
 <option value="draft">draft</option>  
 <option value="rejected">rejected</option>  
 </select>  
 <br />  
 <textarea  
 {...register("content", { required: true })}  
 rows={10}  
 cols={50}  
 />  
 {errors.content && <span>This field is required</span>}  
 <br />  
 <input type="submit" value="Submit" />  
 {formLoading && <p>Loading</p>}  
 </form>  
 );  
};

In this example, the useForm hook is used to handle the form submission. The register function from useForm is used to register input/select fields in the form. The handleSubmit function is used to handle form submission. The onFinish function is used to handle the form submission event. You can modify the data in the onFinish function before it is submitted to the API. For example, you can modify the title and content fields like this:

onFinish({  
 title: modifiedTitle,  
 content: modifiedContent,  
});

onFinish({  
 title: modifiedTitle,  
 content: modifiedContent,  
});

For more information, you can refer to the useForm documentation (https://refine.dev/docs/api-reference/core/hooks/useForm). Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Iam handling all the form submission, in my Autocomplete, I want to modify only the data refine fills when Edit page loads only at initial time. iam modifying data on onChange and form submission but at initial render of the page, when refine fills the data, I want to modify only there

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Refine does not provide a direct way to modify the initial data that is filled when the Edit page loads. The data is fetched and filled based on the id of the record using the useOne hook. However, you can create a workaround by using a state in your component to track the initial render and modify the data accordingly. Here's a general idea of how you can do it:

import { useState, useEffect } from 'react';
import { useForm } from '@refinedev/core';

const PostEdit: React.FC = () => {
  const { formMethods, formLoading, formError, formState } = useForm();
  const [initialRender, setInitialRender] = useState(true);

  useEffect(() => {
    if (initialRender && formState?.data) {
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
      setInitialRender(false);
    }
  }, [formState, formMethods, initialRender]);

  // Rest of your component
};

import { useState, useEffect } from 'react';
import { useForm } from '@refinedev/core';

const PostEdit: React.FC = () => {
  const { formMethods, formLoading, formError, formState } = useForm();
  const [initialRender, setInitialRender] = useState(true);

  useEffect(() => {
    if (initialRender && formState?.data) {
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
      setInitialRender(false);
    }
  }, [formState, formMethods, initialRender]);

  // Rest of your component
};

In this example, we're using a state initialRender to track if it's the first render. When the component mounts, if it's the initial render and the form data is available, we modify the data using the setValue method from formMethods and then set initialRender to false. Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Hey @alfaz_muhammed, You can use useForm's queryOptions.select props. Like this:

useForm({
  queryOptions: {
    select: (rawData) => {
        return {
            data: {
                ...rawData.data,
                // modify your data here
            }
        }
    }
  }
})

useForm({
  queryOptions: {
    select: (rawData) => {
        return {
            data: {
                ...rawData.data,
                // modify your data here
            }
        }
    }
  }
})

@kapa.ai the code you given works, seEffect(() => { if (initialRender && formState?.data) { // Modify the data here formMethods.setValue('yourFieldName', 'yourModifiedValue'); setInitialRender(false); } }, [formState, formMethods, initialRender]); this code works at initial render and it resetValue the id but in the edit page, we have Refresh button, if I click that the data reloads and value go back to before I want my useEffect works there also

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The Refresh button in Refine triggers the useOne hook to fetch the data again. To modify the data when the Refresh button is clicked, you can add a dependency to the useEffect hook to listen for changes in the formState.data object. This will cause the useEffect hook to run whenever the data is refreshed. Here's how you can modify the code:

import { useState, useEffect } from 'react';
import { useForm } from '@refinedev/core';

const PostEdit: React.FC = () => {
  const { formMethods, formLoading, formError, formState } = useForm();
  const [initialRender, setInitialRender] = useState(true);

  useEffect(() => {
    if (formState?.data) {
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
      setInitialRender(false);
    }
  }, [formState.data, formMethods]); // Add formState.data as a dependency

  // Rest of your component
};

import { useState, useEffect } from 'react';
import { useForm } from '@refinedev/core';

const PostEdit: React.FC = () => {
  const { formMethods, formLoading, formError, formState } = useForm();
  const [initialRender, setInitialRender] = useState(true);

  useEffect(() => {
    if (formState?.data) {
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
      setInitialRender(false);
    }
  }, [formState.data, formMethods]); // Add formState.data as a dependency

  // Rest of your component
};

In this example, the useEffect hook will run whenever formState.data changes, which includes when the Refresh button is clicked and the data is re-fetched. Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai there is no prop 'data' from formState

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I apologize for the confusion. You're correct, formState does not have a data property. The formState object contains information about the form state like errors and isSubmitted. The data fetched by useOne hook is available in the queryResult object. You can use queryResult.data to access the fetched data. Here's how you can modify the code:

import { useState, useEffect } from 'react';
import { useForm } from '@refinedev/core';

const PostEdit: React.FC = () => {
  const {  
    formMethods,  
    refineCore: { queryResult },  
  } = useForm();

  useEffect(() => {
    if (queryResult?.data) {
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
    }
  }, [queryResult.data, formMethods]); // Add queryResult.data as a dependency

  // Rest of your component
};

import { useState, useEffect } from 'react';
import { useForm } from '@refinedev/core';

const PostEdit: React.FC = () => {
  const {  
    formMethods,  
    refineCore: { queryResult },  
  } = useForm();

  useEffect(() => {
    if (queryResult?.data) {
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
    }
  }, [queryResult.data, formMethods]); // Add queryResult.data as a dependency

  // Rest of your component
};

In this example, the useEffect hook will run whenever queryResult.data changes, which includes when the Refresh button is clicked and the data is re-fetched. Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai this works fine but one problem also. if i go to list page and come back to edit page without , the data seem to be going to old form how to handle there

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The issue you're facing might be due to the fact that the queryResult.data object is not being updated when you navigate away from the Edit page and then come back. This could be because the useOne hook is not being triggered again, and so the old data is still being used. One way to handle this is to reset the form when the Edit page unmounts. You can do this by returning a cleanup function from the useEffect hook that calls the reset method from formMethods. Here's how you can modify the code:

import {{ useState, useEffect }} from 'react';
import {{ useForm }} from '@refinedev/core';

const PostEdit: React.FC = () => {{
  const {{  
    formMethods,  
    refineCore: {{ queryResult }},  
  }} = useForm();

  useEffect(() => {{
    if (queryResult?.data) {{
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
    }}

    // Cleanup function
    return () => {{
      formMethods.reset(); // Reset the form
    }};
  }}, [queryResult.data, formMethods]); // Add queryResult.data as a dependency

  // Rest of your component
}};

import {{ useState, useEffect }} from 'react';
import {{ useForm }} from '@refinedev/core';

const PostEdit: React.FC = () => {{
  const {{  
    formMethods,  
    refineCore: {{ queryResult }},  
  }} = useForm();

  useEffect(() => {{
    if (queryResult?.data) {{
      // Modify the data here
      formMethods.setValue('yourFieldName', 'yourModifiedValue');
    }}

    // Cleanup function
    return () => {{
      formMethods.reset(); // Reset the form
    }};
  }}, [queryResult.data, formMethods]); // Add queryResult.data as a dependency

  // Rest of your component
}};

In this example, the useEffect hook will run a cleanup function that resets the form when the Edit page unmounts. This should ensure that the old data is not used when you navigate back to the Edit page. Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
