Hi @Sly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To auto-fill fields in a form based on the selected value from a related resource, you can use the useSelect hook provided by Refine. This hook allows you to fetch and manage data from other resources and use it in your components. Here's a basic example of how you can use the useSelect hook to fetch and populate categories in a products resource:

import React from "react";
import { useForm } from "@refinedev/react-hook-form";
import { useSelect } from "@refinedev/core";

export const EditPage: React.FC = () => {
    const {
        refineCore: { onFinish, formLoading, queryResult: productQueryResult },
        register,
        handleSubmit,
    } = useForm<IProduct>({
        refineCoreProps: {
            resource: "products",
            id: 1,
            action: "edit",
        },
    });
    const product = productQueryResult?.data?.data;
    //...
}

import React from "react";
import { useForm } from "@refinedev/react-hook-form";
import { useSelect } from "@refinedev/core";

export const EditPage: React.FC = () => {
    const {
        refineCore: { onFinish, formLoading, queryResult: productQueryResult },
        register,
        handleSubmit,
    } = useForm<IProduct>({
        refineCoreProps: {
            resource: "products",
            id: 1,
            action: "edit",
        },
    });
    const product = productQueryResult?.data?.data;
    //...
}

In this example, the useForm hook is used to manage the form state and the useSelect hook is used to fetch and manage the categories from the categories resource. The selected category is then used to populate the category field in the products resource. To auto-fill the price field based on the selected product in the sells resource, you would need to fetch the product data using the useSelect hook and then use the fetched data to set the value of the price field. Unfortunately, the provided extracts do not include a specific example of how to auto-fill a field based on the selected value from a useSelect hook. For more detailed information and examples, you can refer to the Refine documentation on the useSelect hook (https://refine.dev/docs/core/hooks/use-select/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to do this?

kapa.ai•9mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm sorry for the confusion, but the provided extracts do not contain specific information or code examples on how to auto-fill a field based on the selected value from a useSelect hook in Refine. However, you can generally use the useSelect hook to fetch data from a related resource, and then use this data to set the value of a field in your form. Here's a general idea of how you might do this: 1. Use the useSelect hook to fetch data from the related resource (in your case, the "products" resource). You would pass the resource name and the id of the selected item to the useSelect hook. 2. In the useSelect hook's response, you would get the data for the selected item. You can then use this data to set the value of the "price" field in your "sells" form. 3. To set the value of the "price" field, you can use the setValue function from the useForm hook. You would call setValue('price', selectedProduct.price) to set the price. Please note that this is a general idea and the actual implementation might vary based on your specific use case and the structure of your data. For more detailed information and examples, I recommend checking the Refine documentation (https://refine.dev/docs), specifically the sections on the useForm and useSelect hooks. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai give me an example code

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm sorry for any confusion, but the provided extracts do not contain a specific example of how to auto-fill a field based on the selected value from a useSelect hook. However, I can provide a general example based on the information available:

import { useSelect } from "@refinedev/core";  
import { useForm } from "@refinedev/react-hook-form";

interface IProduct {  
 id: number;  
 title: string;  
 price: number;
}  

const SellCreate: React.FC = () => {  
 const { selectProps } = useSelect<IProduct>({  
 resource: "products",  
 });  

 const { register, setValue, handleSubmit } = useForm();

 const handleSelectChange = (value: any) => {
   const selectedProduct = selectProps.options.find(option => option.value === value);
   if (selectedProduct) {
     setValue('price', selectedProduct.price);
   }
 };

 return (  
   <form onSubmit={handleSubmit(onSubmit)}>
     <label>  
       Select a product:  
       <select onChange={handleSelectChange} {...selectProps} />  
     </label>
     <label>
       Price:
       <input {...register('price')} />
     </label>
     <input type="submit" />
   </form>
 );  
};

import { useSelect } from "@refinedev/core";  
import { useForm } from "@refinedev/react-hook-form";

interface IProduct {  
 id: number;  
 title: string;  
 price: number;
}  

const SellCreate: React.FC = () => {  
 const { selectProps } = useSelect<IProduct>({  
 resource: "products",  
 });  

 const { register, setValue, handleSubmit } = useForm();

 const handleSelectChange = (value: any) => {
   const selectedProduct = selectProps.options.find(option => option.value === value);
   if (selectedProduct) {
     setValue('price', selectedProduct.price);
   }
 };

 return (  
   <form onSubmit={handleSubmit(onSubmit)}>
     <label>  
       Select a product:  
       <select onChange={handleSelectChange} {...selectProps} />  
     </label>
     <label>
       Price:
       <input {...register('price')} />
     </label>
     <input type="submit" />
   </form>
 );  
};

In this example, when a product is selected from the dropdown, the handleSelectChange function is triggered. This function finds the selected product from the options and sets the price field's value to the price of the selected product. Please note that this is a general example and the actual implementation might vary based on your specific use case and the structure of your data. For more detailed information and examples, I recommend checking the Refine documentation (https://refine.dev/docs), specifically the sections on the useForm and useSelect hooks. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
