useAutocomplete

The useAutocomplete hook is used to get data from the API and to manage the Material UI <Autocomplete> component.

Usage with React Hook Form (@pankod/refine-react-hook-form)

We'll demonstrate how to get data at /categories endpoint from https://api.fake-rest.refine.dev REST API.

https://api.fake-rest.refine.dev/categories
{
[
{
id: 1,
title: "E-business",
},
{
id: 2,
title: "Virtual Invoice Avon",
},
{
id: 3,
title: "Unbranded",
},
]
}
pages/posts/create.tsx
import {
Create,
Box,
Autocomplete,
useAutocomplete,
TextField,
} from "@pankod/refine-mui";
import { useForm, Controller } from "@pankod/refine-react-hook-form";

export const PostCreate = () => {
const {
saveButtonProps,
refineCore: { formLoading, queryResult },
register,
control,
formState: { errors },
} = useForm();

const { autocompleteProps } = useAutocomplete<ICategory>({
resource: "categories",
});

return (
<Create isLoading={formLoading} saveButtonProps={saveButtonProps}>
<Box component="form">
<Controller
control={control}
name="category"
rules={{ required: "This field is required" }}
render={({ field }) => (
<Autocomplete
{...autocompleteProps}
{...field}
onChange={(_, value) => {
field.onChange(value);
}}
getOptionLabel={(item) => {
return (
autocompleteProps?.options?.find(
(p) =>
p?.id?.toString() ===
item?.id?.toString(),
)?.title ?? ""
);
}}
isOptionEqualToValue={(option, value) =>
value === undefined ||
option.id.toString() === value.toString()
}
renderInput={(params) => (
<TextField
{...params}
label="Category"
margin="normal"
variant="outlined"
error={!!errors.category}
helperText={errors.category?.message}
required
/>
)}
/>
)}
/>
</Box>
</Create>
);
};

interface ICategory {
id: number;
title: string;
}

The use of useAutocomplete with useForm is demonstrated in the code above. You can use the useAutocomplete hook independently of the useFormhook.

Basic use of Autocomplete

Search functionality

info

By default, refine does the search using the useList hook and passes it to the search parameter. If you get a problem you should check your getList function in your Data Provider. If you want to change this behavior to make client-side filtering, you can examine this documentation.

Options

resource

const { autocompleteProps } = useAutocomplete({
resource: "categories",
});

resource property determines API resource endpoint to fetch records from dataProvider. It returns properly configured options values for <Autocomplete> options.

Refer to Material UI Autocomplete component documentation for detailed info for options. β†’

defaultValue

const { autocompleteProps } = useAutocomplete({
resource: "categories",
defaultValue: "1",
});

Adds extra options to <Autocomplete> component. It uses useMany so defaultValue can be an array of strings like follows.

defaultValue: ["1", "2"],

Refer to the useMany documentation for detailed usage. β†’

tip

Can use defaultValue property when edit a record in <Edit> component.

filters

const { autocompleteProps } = useAutocomplete({
resource: "categories",
filters: [
{
field: "isActive",
operator: "eq",
value: true,
},
],
});

It allows us to add some filters while fetching the data. For example, if you want to list only the active records.

sort

const { autocompleteProps } = useAutocomplete({
resource: "categories",
sort: [
{
field: "title",
order: "asc",
},
],
});

It allows us to sort the options. For example, if you want to sort your list according to title by ascending.

fetchSize

const { autocompleteProps } = useAutocomplete({
resource: "categories",
fetchSize: 20,
});

Amount of records to fetch in the select box.

onSearch

const { autocompleteProps } = useAutocomplete({
resource: "categories",
onSearch: (value) => [
{
field: "title",
operator: "containss",
value,
},
],
});

If defined, it allows us to override the filters to use when fetching the list of records. Thus, it. It should return CrudFilters.

queryOptions

const { autocompleteProps } = useAutocomplete({
resource: "categories",
queryOptions: {
onError: () => {
console.log("triggers when on query return Error");
},
},
});

useQuery options can be set by passing queryOptions property.

defaultValueQueryOptions

When the defaultValue property is given, the useMany data hook is called for the selected records. With this property, you can change the options of this query. If not given, the values given in queryOptions will be used.

const { autocompleteProps } = useAutocomplete({
resource: "categories",
defaultValueQueryOptions: {
onSuccess: (data) => {
console.log("triggers when on query return on success");
},
},
});

useQuery options for default value query can be set by passing queryOptions property.
