useGetLocksLive

Use the useGetLocksLive hook to get all the locks for a resource in real time.

This feature requires a valid Enterprise Edition subscription.

Installation

npm install --save @react-admin/ra-core-ee
# or
yarn add @react-admin/ra-core-ee

Usage

This hook calls dataProvider.getLocks() for the current resource on mount, and subscribes to live updates on the lock/[resource] topic. This means that if a lock is acquired or released by another user while the current user is on the page, the return value will be updated.

import { useRecordContext } from 'ra-core';
import { useGetLocksLive } from '@react-admin/ra-core-ee';
import { Lock } from 'lucide-react';

export const LockField = () => {
    const record = useRecordContext();
    const locks = useGetLocksLive();
    if (!record) return null;
    const lock = locks?.find(lock => lock.recordId === record?.id);
    if (!lock) return <span className="w-4 h-4" />;
    return <Lock className="w-4 h-4" />;
};

useGetLocksLive reads the current resource from the ResourceContext. You can provide it explicitly if you are not in such a context:

const { data: locks } = useGetLocksLive('posts');
