/**
 * An Input component for choosing a reference record. Useful for foreign keys.
 *
 * This component fetches the possible values in the reference resource
 * (using `dataProvider.getList()`), then delegates rendering
 * to a subcomponent, to which it passes the possible choices
 * as the `choices` attribute.
 *
 * Use it with a selector component as child, like `<AutocompleteInput>`,
 * `<SelectInput>`, or `<RadioButtonGroupInput>`.
 *
 * @example
 * export const CommentEdit = (props) => (
 *     <Edit {...props}>
 *         <SimpleForm>
 *             <ReferenceInput label="Post" source="post_id" reference="posts">
 *                 <AutocompleteInput optionText="title" />
 *             </ReferenceInput>
 *         </SimpleForm>
 *     </Edit>
 * );
 *
 * @example
 * export const CommentEdit = (props) => (
 *     <Edit {...props}>
 *         <SimpleForm>
 *             <ReferenceInput label="Post" source="post_id" reference="posts">
 *                 <SelectInput optionText="title" />
 *             </ReferenceInput>
 *         </SimpleForm>
 *     </Edit>
 * );
 *
 * By default, restricts the possible values to 25. You can extend this limit
 * by setting the `perPage` prop.
 *
 * @example
 * <ReferenceInput
 *      source="post_id"
 *      reference="posts"
 *      perPage={100}>
 *     <SelectInput optionText="title" />
 * </ReferenceInput>
 *
 * By default, orders the possible values by id desc. You can change this order
 * by setting the `sort` prop (an object with `field` and `order` properties).
 *
 * @example
 * <ReferenceInput
 *      source="post_id"
 *      reference="posts"
 *      sort={{ field: 'title', order: 'ASC' }}>
 *     <SelectInput optionText="title" />
 * </ReferenceInput>
 *
 * Also, you can filter the query used to populate the possible values. Use the
 * `filter` prop for that.
 *
 * @example
 * <ReferenceInput
 *      source="post_id"
 *      reference="posts"
 *      filter={{ is_published: true }}>
 *     <SelectInput optionText="title" />
 * </ReferenceInput>
 *
 * The enclosed component may filter results. ReferenceInput passes a `setFilter`
 * function as prop to its child component. It uses the value to create a filter
 * for the query - by default { q: [searchText] }. You can customize the mapping
 * searchText => searchQuery by setting a custom `filterToQuery` function prop:
 *
 * @example
 * <ReferenceInput
 *      source="post_id"
 *      reference="posts"
 *      filterToQuery={searchText => ({ title: searchText })}>
 *     <AutocompleteInput optionText="title" />
 * </ReferenceInput>
