<Translate>

The <Translate> component renders a translated message based on a translation key.

Usage

The component will look up the translation for the i18nKey in the i18nProvider and render it. If not found, it will render the children prop.

import { Translate, useRecord, useUpdate } from 'ra-core';

const MarkAsUnreadButton = () => {
    const record = useRecord();
    const update = useUpdate();
    const handleClick = () => {
        update('messages', { id: record.id, data: { isRead: false } });
    };
    return (
        <button onClick={handleClick}>
            <Translate i18nKey="my.messages.actions.mark_as_unread">
                Mark as Unread
            </Translate>
        </button>;
    );
}

Tip: You can also use the useTranslate hook to get a translated message.

Props

Prop	Required	Type	Default	Description
i18nKey	Required	string	-	The translation key.
children	Optional	ReactNode	-	The default content to display if the translation is not found.
options	Optional	Object	-	The options used for pluralization and interpolation.

children

<Translate> renders its child node if translate doesn’t find a translation for the i18nKey.

const messages = {};

<Translate i18nKey="ra.page.loading">Loading</Translate>
// Loading

i18nKey

The translation key, used to look up the translation message.

const messages = {
    resources: {
        reviews: {
            action: {
                reject: 'Reject review',
            },
        },
    },
};

<Translate i18nKey="resources.reviews.action.reject" />
// Reject review

options

Use the options props to pass additional options to the translate function, e.g. for pluralization or interpolation.

const messages = {
    custom: {
        hello_world: 'Hello, %{name}!',
    },
};

<Translate i18nKey="custom.hello_world" options={{ name: 'John' }} />
// Hello, John!

One particular option is smart_count, which is used for pluralization.

const messages = {
    ra: {
        notification: {
            deleted: '1 item deleted |||| %{smart_count} items deleted',
        },
    },
};

<Translate i18nKey="ra.notification.deleted" options={{ smart_count: 2 }} />
// 2 items deleted
