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: ---------------------- Yes, you can modify the value that refine gives to the Autocomplete component. You can use the useForm hook from refine to register your form component and make its values available for both validation and submission. Here's a basic usage of the useForm hook:

const {  
 control,  
 handleSubmit,  
 watch,  
 formState: { errors },  
} = useForm({  
 mode: "onChange",  
 defaultValues,  
});

const {  
 control,  
 handleSubmit,  
 watch,  
 formState: { errors },  
} = useForm({  
 mode: "onChange",  
 defaultValues,  
});

You can use the register method to register an input for validation. This method allows you to access the value of the input field. For example, if you want to modify the form data before it is sent to the API, you can do something like this:

const handleSubmitPostCreate = (values: FormValues) => {  
 const { name, surname } = values;  
 const fullName = `${name} ${surname}`;  
 onFinish({  
 ...value,  
 fullName,  
 });  
};

const handleSubmitPostCreate = (values: FormValues) => {  
 const { name, surname } = values;  
 const fullName = `${name} ${surname}`;  
 onFinish({  
 ...value,  
 fullName,  
 });  
};

In this example, the values received from the user in two separate inputs, name and surname, are sent to the API as fullName. You can refer to the useForm documentation (https://refine.dev/docs/packages/documentation/react-hook-form/useForm/) for more information. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I know hot to modify the values when submission, but the usecase is I have a lot of autocomplete component in the form all of them are registered. but the api response for all of them are object with key and value so refine picks it and give it them. but when submit the form instead of submitting object as values I want to give the key id from the object but modifying every field in submit fucntion is code repeating since iam using a generic autocomplete for all i should modify Autocmplete to return the id if the value given by refine is in ibject form

Let me check the knowledge base for you. One moment! :books: ---------------------- You can modify the Autocomplete component to return the id if the value given by refine is in object form. You can use the useAutocomplete hook from refine to achieve this. This hook sends the request via useMany, gets the data, and marks it as selected. Here's an example of how you can use the useAutocomplete hook:

import { useAutocomplete } from "@refinedev/mui";  
import { Autocomplete, TextField } from "@mui/material";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { autocompleteProps } = useAutocomplete<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
 });  
  
 return (  
 <Autocomplete  
 {...autocompleteProps}  
 getOptionLabel={(item) => item.title}  
 isOptionEqualToValue={(option, value) =>  
 value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()  
 }  
 placeholder="Select a category"  
 renderInput={(params) => (  
 <TextField  
 {...params}  
 label="Category"  
 margin="normal"  
 variant="outlined"  
 required  
 />  
 )}  
 />  
 );  
};

import { useAutocomplete } from "@refinedev/mui";  
import { Autocomplete, TextField } from "@mui/material";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { autocompleteProps } = useAutocomplete<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
 });  
  
 return (  
 <Autocomplete  
 {...autocompleteProps}  
 getOptionLabel={(item) => item.title}  
 isOptionEqualToValue={(option, value) =>  
 value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()  
 }  
 placeholder="Select a category"  
 renderInput={(params) => (  
 <TextField  
 {...params}  
 label="Category"  
 margin="normal"  
 variant="outlined"  
 required  
 />  
 )}  
 />  
 );  
};

In this example, the isOptionEqualToValue prop is used to determine if the option is equal to the value. If the value is an object, it returns the id of the object. You can modify this function to return the id if the value is an object. You can refer to the useAutocomplete documentation (https://refine.dev/docs/api-reference/mui/hooks/useAutocomplete/) for more information. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai this is not what i want when the edit page loads, refine will pick and give the value to the Autocomplete component. I want to access that value inside the Autocmoplete component when refine give them automatically when page loads

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In the useAutocomplete hook, the autocompleteProps object contains the value that refine gives to the Autocomplete component. You can access this value directly from the autocompleteProps object. Here's an example:

const { autocompleteProps } = useAutocomplete<ICategory>({
  resource: "categories",
  defaultValue: 11,
});

console.log(autocompleteProps.value); // This will log the value that refine gives to the Autocomplete component

const { autocompleteProps } = useAutocomplete<ICategory>({
  resource: "categories",
  defaultValue: 11,
});

console.log(autocompleteProps.value); // This will log the value that refine gives to the Autocomplete component

In this example, autocompleteProps.value will contain the value that refine gives to the Autocomplete component when the page loads. Please note that the value property of autocompleteProps will be updated whenever the user selects a different option in the Autocomplete component. You can refer to the useAutocomplete documentation (https://refine.dev/docs/api-reference/mui/hooks/useAutocomplete/) for more information. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai what is mode: onChange in useForm

kapa.ai•12mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The mode: "onChange" option in the useForm hook from React Hook Form specifies when the form input values should be validated. Here's a basic usage of the useForm hook with mode: "onChange":

const {  
 control,  
 handleSubmit,  
 watch,  
 formState: { errors },  
} = useForm({  
 mode: "onChange",  
 defaultValues,  
});

const {  
 control,  
 handleSubmit,  
 watch,  
 formState: { errors },  
} = useForm({  
 mode: "onChange",  
 defaultValues,  
});

In this example, the form input values are validated every time the user changes the value of any input field. If you remove mode: "onChange", the form input values will only be validated when the form is submitted. You can refer to the React Hook Form Validation Examples (https://refine.dev/blog/react-hook-form-validation-examples) for more information. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
