console.js:213 MUI: A component is changing the uncontrolled value state of Autocomplete to be controlled. Elements should not switch from uncontrolled to controlled (or vice versa). Decide between using a controlled or uncontrolled Autocomplete element for the lifetime of the component. The nature of the state is determined during the first render. It's considered controlled if the value is not undefined. im getting this error please help

Hi @tuanna_. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hmm, I don't know enough to give you a confident answer yet. However, the error message you're seeing typically occurs when a component's state changes from being uncontrolled (initial state is undefined) to controlled (initial state is defined). In the context of the Autocomplete component, this could happen if the initial state of the value or inputValue prop is undefined and then later changes to a defined value. Here's an example of how to properly manage state in an Autocomplete component from the extracts:

import React, { useState } from 'react';  
import TextField from '@mui/material/TextField';  
import Autocomplete from '@mui/material/Autocomplete';  
  
const options = ['Value 1', 'Value 2'];  
  
// Creating the manageable states  
export default function ManageableStates() {  
 const [value, setValue] = useState<string | null>(options[0]);  
 const [inputValue, setInputValue] = useState('');  
  
 return (  
 <div>  
 {/* displaying the state values with template literals */}  
 <div>{`value: ${value !== null ? `'${value}'` : 'null'}`}</div>  
 <div>{`inputValue: '${inputValue}'`}</div>  
 <br />  
  
 {/* Calling the Autocomplete component and updating its state features */}  
 <Autocomplete  
 value={value}  
 onChange={(event: any, newValue: string | null) => {  
 setValue(newValue);  
 }}  
 inputValue={inputValue}  
 onInputChange={(event, newInputValue) => {  
 setInputValue(newInputValue);  
 }}  
 id="manageable-states-demo"  
 options={options}  
 sx={{ width: 300 }}  
 renderInput={(params) => <TextField {...params} label="Manage State" />}  
 />  
 </div>  
 );  
}

import React, { useState } from 'react';  
import TextField from '@mui/material/TextField';  
import Autocomplete from '@mui/material/Autocomplete';  
  
const options = ['Value 1', 'Value 2'];  
  
// Creating the manageable states  
export default function ManageableStates() {  
 const [value, setValue] = useState<string | null>(options[0]);  
 const [inputValue, setInputValue] = useState('');  
  
 return (  
 <div>  
 {/* displaying the state values with template literals */}  
 <div>{`value: ${value !== null ? `'${value}'` : 'null'}`}</div>  
 <div>{`inputValue: '${inputValue}'`}</div>  
 <br />  
  
 {/* Calling the Autocomplete component and updating its state features */}  
 <Autocomplete  
 value={value}  
 onChange={(event: any, newValue: string | null) => {  
 setValue(newValue);  
 }}  
 inputValue={inputValue}  
 onInputChange={(event, newInputValue) => {  
 setInputValue(newInputValue);  
 }}  
 id="manageable-states-demo"  
 options={options}  
 sx={{ width: 300 }}  
 renderInput={(params) => <TextField {...params} label="Manage State" />}  
 />  
 </div>  
 );  
}

In this example, the initial state of value and inputValue are defined, making the Autocomplete component controlled for its entire lifecycle.

@kapa.ai im assigning it field instead, is it okay or i still have to make a value state <Controller control={control} name="status" render={({ field }) => ( <Autocomplete {...field} options={statusOptions} getOptionLabel={(option) => typeof option === "string" ? option : option.label } onChange={(_, value) => { if (typeof value === "string") { const selectedOption = statusOptions.find( (option) => option.value === value ); field.onChange(selectedOption); } else { field.onChange(value); } }} isOptionEqualToValue={(option, value) => value === undefined || option?.value?.toString() === (value?.value ?? value)?.toString() } renderInput={(params) => ( <TextField {...params} label={t("products.filter.status.label")} placeholder={t("products.filter.status.placeholder")} margin="normal" variant="outlined" size="small" /> )} /> )} />

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, it's perfectly fine to use the field prop from the Controller component of react-hook-form to manage the state of the Autocomplete component. This is a common pattern when using react-hook-form with Material-UI components. In your code, you're spreading the field prop to pass down onChange, onBlur, and value to the Autocomplete component. You're also providing a custom onChange handler to process the selected value before calling field.onChange. Here's the relevant part of your code:

<Controller
  control={control}
  name="status"
  render={({ field }) => (
    <Autocomplete
      {...field}
      options={statusOptions}
      getOptionLabel={(option) =>
        typeof option === "string" ? option : option.label
      }
      onChange={(_, value) => {
        if (typeof value === "string") {
          const selectedOption = statusOptions.find(
            (option) => option.value === value
          );
          field.onChange(selectedOption);
        } else {
          field.onChange(value);
        }
      }}
      // rest of your code...
    />
  )}
/>

<Controller
  control={control}
  name="status"
  render={({ field }) => (
    <Autocomplete
      {...field}
      options={statusOptions}
      getOptionLabel={(option) =>
        typeof option === "string" ? option : option.label
      }
      onChange={(_, value) => {
        if (typeof value === "string") {
          const selectedOption = statusOptions.find(
            (option) => option.value === value
          );
          field.onChange(selectedOption);
        } else {
          field.onChange(value);
        }
      }}
      // rest of your code...
    />
  )}
/>

This approach makes the Autocomplete component controlled without needing to manually create a state with useState. The state is managed by react-hook-form via the Controller component. For more information on using react-hook-form with Material-UI, you can refer to the refine documentation (https://refine.dev/docs/api-reference/mui/hooks/useAutocomplete/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai then why is it still saying that : console.js:213 MUI: A component is changing the uncontrolled value state of Autocomplete to be controlled. Elements should not switch from uncontrolled to controlled (or vice versa). Decide between using a controlled or uncontrolled Autocomplete element for the lifetime of the component. The nature of the state is determined during the first render. It's considered controlled if the value is not undefined.

kapa.ai•11mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The error message you're seeing typically occurs when a component's state changes from being uncontrolled (initial state is undefined) to controlled (initial state is defined). In the context of the Autocomplete component, this could happen if the initial state of the value prop is undefined and then later changes to a defined value. When using react-hook-form with the Controller component, the initial value is determined by the defaultValues you provide to the useForm hook. If you don't provide a default value for the "status" field, then the initial value will be undefined, making the Autocomplete component uncontrolled initially. To fix this issue, you should provide a default value for the "status" field when initializing your form. Here's an example:

const { control } = useForm({
  defaultValues: {
    status: '', // provide a default value
    // other fields...
  },
});

const { control } = useForm({
  defaultValues: {
    status: '', // provide a default value
    // other fields...
  },
});

This will ensure that the Autocomplete component is controlled for its entire lifecycle, preventing the error message you're seeing.

@kapa.ai const { register, handleSubmit, control } = useForm< BaseRecord, HttpError, IColorFilterVariables >({ defaultValues: { status: 'getDefaultFilter("status.text", filters, "eq")', q: getDefaultFilter("q", filters, "eq"), code: getDefaultFilter("code", filters, "eq"), }, }); is this default value for the "status" field valid?

kapa.ai•11mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The defaultValues you've provided in the useForm hook are actually function calls, not actual values. The defaultValues object should contain the actual default values for your form fields. If getDefaultFilter("status.text", filters, "eq") is a function call that returns the default value for the "status" field, you should call this function outside the useForm hook and assign its return value to the "status" field in defaultValues. Here's how you can do it:

const defaultStatus = getDefaultFilter("status.text", filters, "eq");
const defaultQ = getDefaultFilter("q", filters, "eq");
const defaultCode = getDefaultFilter("code", filters, "eq");

const { register, handleSubmit, control } = useForm<BaseRecord, HttpError, IColorFilterVariables>({
  defaultValues: {
    status: defaultStatus,
    q: defaultQ,
    code: defaultCode,
  },
});

const defaultStatus = getDefaultFilter("status.text", filters, "eq");
const defaultQ = getDefaultFilter("q", filters, "eq");
const defaultCode = getDefaultFilter("code", filters, "eq");

const { register, handleSubmit, control } = useForm<BaseRecord, HttpError, IColorFilterVariables>({
  defaultValues: {
    status: defaultStatus,
    q: defaultQ,
    code: defaultCode,
  },
});

In this code, getDefaultFilter("status.text", filters, "eq"), getDefaultFilter("q", filters, "eq"), and getDefaultFilter("code", filters, "eq") are called first, and their return values are assigned to defaultStatus, defaultQ, and defaultCode respectively. These variables are then used as the default values for the "status", "q", and "code" fields in the form. For more information, you can refer to the refine documentation (https://refine.dev/docs/api-reference/mui/hooks/useAutocomplete/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai explain how this works: export const getDefaultFilter = ( columnName: string, filters?: CrudFilters, operatorType: CrudOperators = "eq", ): CrudFilter["value"] | undefined => { const filter = filters?.find((filter) => { if ( filter.operator !== "or" && filter.operator !== "and" && "field" in filter ) { const { operator, field } = filter; return field === columnName && operator === operatorType; } return undefined; }); if (filter) { return filter.value || []; } return undefined; };

kapa.ai•11mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The getDefaultFilter function is used to find and return the default filter value for a given column from the provided filters. Here's a breakdown of how it works: 1. The function takes three parameters: - columnName: The name of the column for which you want to find the default filter value. - filters: An optional array of filters. Each filter is an object that includes a field, operator, and value. - operatorType: The type of operator for the filter. It defaults to "eq" if not provided. 2. The function first tries to find a filter from the filters array where the field matches the columnName and the operator matches the operatorType. It ignores filters where the operator is "or" or "and".

const filter = filters?.find((filter) => {
    if (
        filter.operator !== "or" &&
        filter.operator !== "and" &&
        "field" in filter
    ) {
        const { operator, field } = filter;
        return field === columnName && operator === operatorType;
    }
    return undefined;
});

const filter = filters?.find((filter) => {
    if (
        filter.operator !== "or" &&
        filter.operator !== "and" &&
        "field" in filter
    ) {
        const { operator, field } = filter;
        return field === columnName && operator === operatorType;
    }
    return undefined;
});

3. If such a filter is found, the function returns the value of the filter. If the value is undefined or null, it returns an empty array.

if (filter) {
    return filter.value || [];
}

if (filter) {
    return filter.value || [];
}

4. If no matching filter is found, the function returns undefined.

return undefined;

return undefined;

This function is useful when you want to initialize your form or table with default filter values. For example, you might want to show only the rows where the status is "active" by default. You can use this function to find the default filter value for the "status" column and use it to initialize your form or table. For more information, you can refer to the refine documentation (https://refine.dev/docs/api-reference/core/hooks/useTable/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
