hook form mui autocomplete

I am trying to report error if the value is not in the options to the autocomplete . <FormControl sx={{ padding: 0 }}> <Controller control={control} name={fieldName} rules={{ required: t("errors.required.field", { field: fieldName }), validate: (value) => { console.log(value, options); if (!options.some((option) => option.id === value.id)) { return t("errors.invalid.option", { field: fieldName }); } return true; }, }}

Hi @Joe Gaffney. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To report an error if the value is not in the options for a Material UI Autocomplete component using react-hook-form, you can use the Controller component to manage the form state and validation. The validate function in the rules prop can be used to check if the selected value exists in the options. Here's an example based on the knowledge sources provided:

import { Controller } from "react-hook-form";
import { Autocomplete, TextField } from "@mui/material";

<Controller
    control={control}
    name="category"
    rules={{
        required: "This field is required",
        validate: (value) => {
            if (!options.some((option) => option.id === value.id)) {
                return "Invalid option selected";
            }
            return true;
        },
    }}
    render={({ field, fieldState: { error } }) => (
        <Autocomplete
            {...field}
            options={options}
            getOptionLabel={(option) => option.title}
            isOptionEqualToValue={(option, value) => option.id === value.id}
            renderInput={(params) => (
                <TextField
                    {...params}
                    label="Category"
                    error={!!error}
                    helperText={error ? error.message : null}
                    required
                />
            )}
            onChange={(_, value) => field.onChange(value)}
        />
    )}
/>

import { Controller } from "react-hook-form";
import { Autocomplete, TextField } from "@mui/material";

<Controller
    control={control}
    name="category"
    rules={{
        required: "This field is required",
        validate: (value) => {
            if (!options.some((option) => option.id === value.id)) {
                return "Invalid option selected";
            }
            return true;
        },
    }}
    render={({ field, fieldState: { error } }) => (
        <Autocomplete
            {...field}
            options={options}
            getOptionLabel={(option) => option.title}
            isOptionEqualToValue={(option, value) => option.id === value.id}
            renderInput={(params) => (
                <TextField
                    {...params}
                    label="Category"
                    error={!!error}
                    helperText={error ? error.message : null}
                    required
                />
            )}
            onChange={(_, value) => field.onChange(value)}
        />
    )}
/>

In this example, the validate function checks if the selected value's id is present in the options array. If not, it returns an error message. The renderInput function of the Autocomplete component uses a TextField to display any validation errors. For more information, you can refer to the refine documentation on using useAutocomplete with CRUD components and useForm (https://refine.dev/docs/ui-integrations/material-ui/hooks/use-auto-complete/#how-do-i-use-it-with-crud-components-and-useform). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai this is not working is the validate only ran on change issue i am having is my options change based on previous feild choices.

Let me check the knowledge base for you again. One moment! :books: ---------------------- To handle dynamic options in a react-hook-form setup with Material UI's Autocomplete, you need to ensure that the validation logic is triggered whenever the options change. The validate function in the rules prop is typically run on change, but you can manually trigger validation when the options change by using the trigger method from react-hook-form. Here's how you can approach this: 1. Use the useEffect Hook: Monitor changes to the options and trigger validation when they change. 2. Trigger Validation: Use the trigger method from react-hook-form to manually validate the field when the options change. Here's an example implementation:

import { useEffect } from "react";
import { Controller, useForm } from "react-hook-form";
import { Autocomplete, TextField } from "@mui/material";

const MyForm = ({ options, control }) => {
    const { trigger } = useForm();

    useEffect(() => {
        // Trigger validation when options change
        trigger("category");
    }, [options, trigger]);
return (
        <Controller
            control={control}
            name="category"
            rules={{
                required: "This field is required",
                validate: (value) => {
                    if (!options.some((option) => option.id === value.id)) {
                        return "Invalid option selected";
                    }
                    return true;
                },
            }}
            render={({ field, fieldState: { error } }) => (
                <Autocomplete
                    {...field}
                    options={options}
                    getOptionLabel={(option) => option.title}
                    isOptionEqualToValue={(option, value) => option.id === value.id}
                    renderInput={(params) => (
                        <TextField
                            {...params}
                            label="Category"
                            error={!!error}
                            helperText={error ? error.message : null}
                            required
                        />
                    )}
                    onChange={(_, value) => field.onChange(value)}
                />
            )}
        />
    );
};

export default MyForm;

import { useEffect } from "react";
import { Controller, useForm } from "react-hook-form";
import { Autocomplete, TextField } from "@mui/material";

const MyForm = ({ options, control }) => {
    const { trigger } = useForm();

    useEffect(() => {
        // Trigger validation when options change
        trigger("category");
    }, [options, trigger]);
return (
        <Controller
            control={control}
            name="category"
            rules={{
                required: "This field is required",
                validate: (value) => {
                    if (!options.some((option) => option.id === value.id)) {
                        return "Invalid option selected";
                    }
                    return true;
                },
            }}
            render={({ field, fieldState: { error } }) => (
                <Autocomplete
                    {...field}
                    options={options}
                    getOptionLabel={(option) => option.title}
                    isOptionEqualToValue={(option, value) => option.id === value.id}
                    renderInput={(params) => (
                        <TextField
                            {...params}
                            label="Category"
                            error={!!error}
                            helperText={error ? error.message : null}
                            required
                        />
                    )}
                    onChange={(_, value) => field.onChange(value)}
                />
            )}
        />
    );
};

export default MyForm;

In this example, the useEffect hook is used to watch for changes in the options array. Whenever the options change, the trigger function is called to re-validate the "category" field. This ensures that the validation logic is applied even when the options are updated based on previous field choices. For more details on using react-hook-form with dynamic data, you can refer to the React Hook Form documentation (https://react-hook-form.com/docs/useform). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i short of just want to redraw if the options change or rest the value

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To reset the value or redraw the Autocomplete component when the options change, you can use the useEffect hook to monitor changes in the options and reset the field value using the setValue method from react-hook-form. This approach ensures that the Autocomplete component updates its state whenever the options change. Here's how you can implement this:

import { useEffect } from "react";
import { Controller, useForm } from "react-hook-form";
import { Autocomplete, TextField } from "@mui/material";

                    onChange={(_, value) => field.onChange(value)}

            )}
        />
    );
};

export default MyForm;

import { useEffect } from "react";

            )}
        />
    );
};

export default MyForm;

In this example, the useEffect hook is used to reset the "category" field to null whenever the options array changes. This effectively redraws the Autocomplete component with the updated options and resets the selected value, ensuring that the component reflects the current state of the options.

@kapa.ai how i can reset a value of the form feild outsidte from a use effect

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To reset the value of a form field outside of a useEffect hook using react-hook-form, you can use the reset or setValue methods provided by the useForm hook. These methods can be called in response to any event or condition in your component. Here's an example of how you can reset a form field value using a button click:

import React from "react";
import { useForm, Controller } from "react-hook-form";
import { TextField, Button } from "@mui/material";

const MyForm = () => {
    const { control, setValue, reset } = useForm({
        defaultValues: {
            category: "",
        },
    });

    const handleReset = () => {
        // Reset the specific field
        setValue("category", "");

        // Alternatively, reset the entire form to default values
        // reset();
    };

    return (
        <form>
            <Controller
                control={control}
                name="category"
                render={({ field }) => (
                    <TextField
                        {...field}
                        label="Category"
                        variant="outlined"
                    />
                )}
            />
            <Button onClick={handleReset} variant="contained" color="primary">
                Reset Category
            </Button>
        </form>
    );
};

export default MyForm;

import React from "react";
import { useForm, Controller } from "react-hook-form";
import { TextField, Button } from "@mui/material";

const MyForm = () => {
    const { control, setValue, reset } = useForm({
        defaultValues: {
            category: "",
        },
    });

    const handleReset = () => {
        // Reset the specific field
        setValue("category", "");

        // Alternatively, reset the entire form to default values
        // reset();
    };

    return (
        <form>
            <Controller
                control={control}
                name="category"
                render={({ field }) => (
                    <TextField
                        {...field}
                        label="Category"
                        variant="outlined"
                    />
                )}
            />
            <Button onClick={handleReset} variant="contained" color="primary">
                Reset Category
            </Button>
        </form>
    );
};

export default MyForm;

In this example, the handleReset function is called when the "Reset Category" button is clicked. It uses the setValue method to reset the "category" field to an empty string. Alternatively, you can use the reset method to reset the entire form to its default values. For more details on using react-hook-form, you can refer to the React Hook Form documentation (https://react-hook-form.com/docs/useform). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai is there not a way with ther controller

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, you can reset a form field value using the Controller component in react-hook-form. The Controller component itself doesn't directly provide a method to reset values, but you can use the setValue method from the useForm hook in conjunction with Controller to achieve this. Here's how you can do it:

import React from "react";
import { useForm, Controller } from "react-hook-form";
import { TextField, Button } from "@mui/material";

const MyForm = () => {
    const { control, setValue } = useForm({
        defaultValues: {
            category: "",
        },
    });

    const handleReset = () => {
        // Reset the specific field using setValue
        setValue("category", "");
    };

    return (
        <form>
            <Controller
                control={control}
                name="category"
                render={({ field }) => (
                    <TextField
                        {...field}
                        label="Category"
                        variant="outlined"
                    />
                )}
            />
            <Button onClick={handleReset} variant="contained" color="primary">
                Reset Category
            </Button>
        </form>
    );
};

export default MyForm;

import React from "react";
import { useForm, Controller } from "react-hook-form";
import { TextField, Button } from "@mui/material";

const MyForm = () => {
    const { control, setValue } = useForm({
        defaultValues: {
            category: "",
        },
    });

    const handleReset = () => {
        // Reset the specific field using setValue
        setValue("category", "");
    };

    return (
        <form>
            <Controller
                control={control}
                name="category"
                render={({ field }) => (
                    <TextField
                        {...field}
                        label="Category"
                        variant="outlined"
                    />
                )}
            />
            <Button onClick={handleReset} variant="contained" color="primary">
                Reset Category
            </Button>
        </form>
    );
};

export default MyForm;

In this example, the handleReset function is used to reset the "category" field by calling setValue with an empty string. This approach allows you to reset the field value while using the Controller component to manage the form field. For more information on using react-hook-form with Controller, you can refer to the React Hook Form documentation (https://react-hook-form.com/docs/useform). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
