`useListController`

useListController contains the headless logic of the <List> component. It’s useful to create a custom List view. It’s also the base hook when building a custom view with another UI kit than Material UI.

List view built with Ant Design

useListController reads the list parameters from the URL, calls dataProvider.getList(), prepares callbacks for modifying the pagination, filters, sort and selection, and returns them together with the data. Its return value matches the ListContext shape.

useListController is used internally by <List> and <ListBase>. If your list view uses react-admin components like <Datagrid>, prefer <ListBase> to useListController as it takes care of creating a <ListContext>.

Usage

useListController expects a parameters object defining the list sorting, pagination, and filters. It returns an object with the fetched data, and callbacks to modify the list parameters.

Here the code for the post list view above, built with Ant Design:

import { useListController } from 'react-admin'; 
import { Card, Table, Button } from 'antd';
import {
  CheckCircleOutlined,
  PlusOutlined,
  EditOutlined,
} from '@ant-design/icons';
import { Link } from 'react-router-dom';

const PostList = () => {
  const { data, page, total, setPage, isPending } = useListController({
    sort: { field: 'published_at', order: 'DESC' },
    perPage: 10,
  });
  const handleTableChange = (pagination) => {
    setPage(pagination.current);
  };
  return (
    <>
      <div style={{ margin: 10, textAlign: 'right' }}>
        <Link to="/posts/create">
          <Button icon={<PlusOutlined />}>Create</Button>
        </Link>
      </div>
      <Card bodyStyle={{ padding: '0' }} loading={isPending}>
        <Table
          size="small"
          dataSource={data}
          columns={columns}
          pagination={{ current: page, pageSize: 10, total }}
          onChange={handleTableChange}
        />
      </Card>
    </>
  );
};

const columns = [
  { title: 'Id', dataIndex: 'id', key: 'id' },
  { title: 'Title', dataIndex: 'title', key: 'title' },
  {
    title: 'Publication date',
    dataIndex: 'published_at',
    key: 'pub_at',
    render: (value) => new Date(value).toLocaleDateString(),
  },
  {
    title: 'Commentable',
    dataIndex: 'commentable',
    key: 'commentable',
    render: (value) => (value ? <CheckCircleOutlined /> : null),
  },
  {
    title: 'Actions',
    render: (_, record) => (
      <Link to={`/posts/${record.id}`}>
        <Button icon={<EditOutlined />}>Edit</Button>
      </Link>
    ),
  },
];

export default PostList;

When using react-admin components, it’s common to call useListController() without parameters, and to put the result in a ListContext to make it available to the rest of the component tree.

import { 
    useListController,
    ListContextProvider
} from 'react-admin';

const MyList = () => {
    const listContext = useListController();
    return (
        <ListContextProvider value={listContext}>
            {children}
        </ListContextProvider>
    );
};

Parameters

useListController expects an object as parameter. All keys are optional.

debounce: Debounce time in ms for the setFilters callbacks
disableAuthentication: Set to true to allow anonymous access to the list
disableSyncWithLocation: Set to true to have more than one list per page
exporter: Exporter function
filter: Permanent filter, forced over the user filter
filterDefaultValues: Default values for the filter form
perPage: Number of results per page
queryOptions: React-query options for the useQuery call
resource: Resource name, e.g. ‘posts’ ; defaults to the current resource context
sort: Current sort value, e.g. { field: 'published_at', order: 'DESC' }
storeKey: Key used to differentiate the list from another sharing the same resource, in store managed states

Here are their default values:

import {  
    useListController,
    defaultExporter,
    ListContextProvider
} from 'react-admin';

const MyList = ({
    debounce = 500,
    disableAuthentication = false,
    disableSyncWithLocation = false,
    exporter = defaultExporter,
    filter = undefined,
    filterDefaultValues = undefined,
    perPage = 10,
    queryOptions = undefined,
    resource = '',
    sort = { field: 'id', order: 'DESC' },
    storeKey = undefined,
}) => {
    const listContext = useListController({
        debounce,
        disableAuthentication,
        disableSyncWithLocation,
        exporter,
        filter,
        filterDefaultValues,
        perPage,
        queryOptions,
        resource,
        sort,
        storeKey,
    });
    return (
        <ListContextProvider value={listContext}>
            {children}
        </ListContextProvider>
    );
};

`storeKey`

To display multiple lists of the same resource and keep distinct store states for each of them (filters, sorting and pagination), specify unique keys with the storeKey property.

In case no storeKey is provided, the states will be stored with the following key: ${resource}.listParams.

Note: Please note that selection state will remain linked to a resource-based key as described here.

If you want to disable the storage of list parameters altogether for a given list, you can use the disableSyncWithLocation prop.

In the example below, both lists TopPosts and FlopPosts use the same resource (‘posts’), but their controller states are stored separately (under the store keys 'top' and 'flop' respectively).

import { useListController } from 'react-admin';

const OrderedPostList = ({
    storeKey,
    sort,
}) => {
    const params = useListController({
        resource: 'posts',
        sort,
        storeKey,
    });
    return (
        <div>
            <ul style={styles.ul}>
                {!params.isPending &&
                    params.data.map(post => (
                        <li key={`post_${post.id}`}>
                            {post.title} - {post.votes} votes
                        </li>
                    ))}
            </ul>
        </div>
    );
};

const TopPosts = (
    <OrderedPostList storeKey="top" sort={{ field: 'votes', order: 'DESC' }} />
);
const FlopPosts = (
    <OrderedPostList storeKey="flop" sort={{ field: 'votes', order: 'ASC' }} />
);

You can disable this feature by setting the storeKey prop to false. When disabled, parameters will not be persisted in the store.

Return Value

useListController returns an object with the following keys:

const {
    // Data
    data, // Array of the list records, e.g. [{ id: 123, title: 'hello world' }, { ... }
    total, // Total number of results for the current filters, excluding pagination. Useful to build the pagination controls, e.g. 23

    resource, // Resource name, deduced from the location. e.g. 'posts'
    refetch, // Callback for fetching the list data again
} = useListController();

Using `setFilters` to Update Filters

The setFilters method is used to update the filters. It takes three arguments:

filters: an object containing the new filter values
displayedFilters: an object containing the new displayed filters
debounced: set to true to debounce the call to setFilters (false by default)

You can use it to update the list filters:

import { useState } from 'react';
import { useListController } from 'react-admin';

const OfficeList = () => {
    const { filterValues, setFilters, data, isLoading } = useListController({ resource: 'offices' });
    const [formValues, setFormValues] = useState(filterValues);

    const handleChange = (event) => {
        setFormValues(formValues => ({
            ...formValues,
            [event.target.name]: event.target.value
        }));
    };

    const handleSubmit = (event) => {
        event.preventDefault();
        setFilters(filterFormValues);
    };

    if (isLoading) return <div>Loading...</div>;

    return (
        <>
            <form onSubmit={handleSubmit}>
                <input name="country" value={formValues.country} onChange={handleChange} />
                <input name="city" value={formValues.city} onChange={handleChange} />
                <input name="zipcode" value={formValues.zipcode} onChange={handleChange} />
                <input type="submit">Filter</input>
            </form>
            <ul>
                {data.map(record => (
                    <li key={record.id}>{record.name}</li>
                ))}
            </ul>
        </>
    );
};
