`useHardDeleteMany`

This hook allows calling dataProvider.hardDeleteMany() when the callback is executed and deleting an array of deleted records based on their ids.

Warning: The ids here are the IDs of the deleted records, and not the IDs of the actual records that have been deleted.

const [hardDeleteMany, { data, isPending, error }] = useHardDeleteMany(
 { ids, meta },
 options,
);

The hardDeleteMany() method can be called with the same parameters as the hook:

const [hardDeleteMany, { data, isPending, error }] = useHardDeleteMany();
// ...
hardDeleteMany(
 { ids, meta },
 options,
);

So, should you pass the parameters when calling the hook, or when executing the callback? It’s up to you; but if you have the choice, we recommend passing the parameters when calling the hardDeleteMany callback (second example).

Usage

// set params when calling the hook
import { useListContext } from 'react-admin';
import { useHardDeleteMany } from '@react-admin/ra-soft-delete';
const BulkHardDeletePostsButton = () => {
 const { selectedIds } = useListContext();
 const [hardDeleteMany, { isPending, error }] = useHardDeleteMany(
 { ids: selectedIds }
 );
 const handleClick = () => {
 hardDeleteMany();
 }
 if (error) { return <p>ERROR</p>; }
 return <button disabled={isPending} onClick={handleClick}>Delete selected posts</button>;
};
// set params when calling the hardDeleteMany callback
import { useListContext } from 'react-admin';
import { useHardDeleteMany } from '@react-admin/ra-soft-delete';
const BulkHardDeletePostsButton = () => {
 const { selectedIds } = useListContext();
 const [hardDeleteMany, { isPending, error }] = useHardDeleteMany();
 const handleClick = () => {
 hardDeleteMany(
 { ids: seletedIds }
 );
 }
 if (error) { return <p>ERROR</p>; }
 return <button disabled={isPending} onClick={handleClick}>Delete selected posts</button>;
};

TypeScript

The useHardDeleteMany hook accepts a generic parameter for the record type and another for the error type:

useHardDeleteMany<Product, Error>(undefined, undefined, {
 onError: (error) => {
 // TypeScript knows that error is of type Error
 },
 onSettled: (data, error) => {
 // TypeScript knows that data is of type Product['id'][]
 // TypeScript knows that error is of type Error
 },
});
