useAutocomplete

useAutocomplete hook allows you to manage Material UI <Autocomplete> component when records in a resource needs to be used as select options.

This hook uses the useList hook for fetching data. Refer to useList hook for details. →

DERIVATIVES

If you're looking for a complete select library, refine has out-of-the-box support for the libraries below:

Basic Usage​

Here is a basic example of how to use useAutocomplete hook.

localhost:3000
Live previews only work with the latest documentation.
import {
    Autocomplete,
    useAutocomplete,
    TextField,
} from "@pankod/refine-mui";

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

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

    return (
        <Autocomplete
            {...autocompleteProps}
            getOptionLabel={(item) => item.title}
            isOptionEqualToValue={(option, value) =>
                value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()
            }
            placeholder="Select a category"
            renderInput={(params) => (
                <TextField
                    {...params}
                    label="Category"
                    margin="normal"
                    variant="outlined"
                    required
                />
            )}
        />
    );
};

Realtime Updates​

This feature is only available if you use a Live Provider

When useAutocomplete hook is mounted, it passes some parameters (channel, resource etc.) to the subscribe method from the liveProvider. It is useful when you want to subscribe to the live updates.

Refer to the liveProvider documentation for more information →

Properties​

resource
required
​

It will be passed to the getList method from the dataProvider as parameter via the useList hook. The parameter is usually used as an API endpoint path. It all depends on how to handle the resource in the getList method. See the creating a data provider section for an example of how resources are handled.

useAutocomplete({
  resource: "categories",
});

sort​

It allows to show the options in the desired order. sort will be passed to the getList method from the dataProvider as parameter via the useList hook. It is used to send sort query parameters to the API.

Refer to the CrudSorting interface for more information →

useAutocomplete({
  sort: [
    {
      field: "title",
      order: "asc",
    },
  ],
});

import {
    Autocomplete,
    useAutocomplete,
    TextField,
    Button,
} from "@pankod/refine-mui";

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

const PostCreate: React.FC = () => {
    const [order, setOrder] = React.useState<"asc" | "desc">("asc");
    const { autocompleteProps } = useAutocomplete<ICategory>({
        resource: "categories",
        sort: [
            {
                field: "title",
                order,
            }
        ]
    });

    return (
        <>
            <Autocomplete
                {...autocompleteProps}
                getOptionLabel={(item) => item.title}
                isOptionEqualToValue={(option, value) =>
                    value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()
                }
                placeholder="Select a category"
                renderInput={(params) => (
                    <TextField
                        {...params}
                        label="Category"
                        margin="normal"
                        variant="outlined"
                        required
                    />
                )}
            />
            <Button 
                onClick={() => setOrder(order === "asc" ? "desc" : "asc")} 
                variant="contained" 
                size="small"
            >Toggle Order</Button>
        </>
    );
};

filters​

It is used to show options by filtering them. filters will be passed to the getList method from the dataProvider as parameter via the useList hook. It is used to send filter query parameters to the API.

Refer to the CrudFilters interface for more information →

useAutocomplete({
  filter: [
    {
      field: "isActive",
      operator: "eq",
      value: true,
    },
  ],
});

defaultValue​

Allows to make options selected by default. Adds extra options to <select> component. In some cases like there are many entries for the <select> and pagination is required, defaultValue may not be present in the current visible options and this can break the <select> component. To avoid such cases, A seperate useMany query is sent to the backend with the defaultValue and appended to the options of <select>, ensuring the default values exist in the current options array. Since it uses useMany to query the necessary data, the defaultValue can be a single value or an array of values like the following:

useAutocomplete({
  defaultValue: 1, // or [1, 2]
});

Refer to the useMany documentation for detailed usage. →

debounce​

It allows us to debounce the onSearch function.

useAutocomplete({
  debounce: 500,
});

queryOptions​

queryOptions is used to pass additional options to the useQuery hook. It is useful when you want to pass additional options to the useQuery hook.

Refer to the useQuery documentation for more information →

useAutocomplete({
  queryOptions: {
    retry: 3,
  },
});

pagination​

pagination will be passed to the getList method from the dataProvider as parameter. It is used to send pagination query parameters to the API.

current​

You can pass the current page number to the pagination property.

useAutocomplete({
  pagination: {
    current: 2,
  },
});

pageSize​

You can pass the pageSize to the pagination property.

useAutocomplete({
  pagination: {
    pageSize: 20,
  },
});

hasPagination​

Default: false

hasPagination will be passed to the getList method from the dataProvider as parameter via the useList hook. It is used to determine whether to use server-side pagination or not.

useAutocomplete({
  hasPagination: false,
});

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.

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

onSearch​

It allows us to AutoComplete the options.

Refer to the CrudFilters interface for more information →

localhost:3000
Live previews only work with the latest documentation.
import {
    Autocomplete,
    useAutocomplete,
    TextField,
} from "@pankod/refine-mui";

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

const PostCreate: React.FC = () => {
    const { autocompleteProps } = useAutocomplete<ICategory>({
        resource: "categories",
        onSearch: (value) => [
            {
                field: "title",
                operator: "contains",
                value,
            }
        ]
    });

    return (
        <Autocomplete
            {...autocompleteProps}
            getOptionLabel={(item) => item.title}
            isOptionEqualToValue={(option, value) =>
                value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()
            }
            placeholder="Select a category"
            renderInput={(params) => (
                <TextField
                    {...params}
                    label="Category"
                    margin="normal"
                    variant="outlined"
                    required
                />
            )}
        />
    );
};

If onSearch is used, it will override the existing filters. :::

Client-side filtering​

Sometimes, you may want to filter the options on the client-side. You can do this by passing onSearch function as undefined. This will disable the server-side filtering and will filter the options on the client-side.

import { createFilterOptions } from "@pankod/refine-mui";

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

const filterOptions = createFilterOptions({
  matchFrom: "start",
  stringify: (option: any) => option.title,
});

<Autocomplete
  {...autocompleteProps}
  getOptionLabel={(item) => item.title}
  onInputChange={(event, value) => {}}
  filterOptions={filterOptions}
  isOptionEqualToValue={(option, value) =>
    value === undefined ||
    option?.id?.toString() === (value?.id ?? value)?.toString()
  }
  placeholder="Select a category"
  renderInput={(params) => (
    <TextField
      {...params}
      label="Category"
      margin="normal"
      variant="outlined"
      required
    />
  )}
/>;

metaData​

metaData is used following two purposes:

  • To pass additional information to data provider methods.
  • Generate GraphQL queries using plain JavaScript Objects (JSON). Please refer GraphQL for more information.

In the following example, we pass the headers property in the metaData object to the create method. With similar logic, you can pass any properties to specifically handle the data provider methods.

useAutocomplete({
  metaData: {
    headers: { "x-meta-data": "true" },
  },
});

const myDataProvider = {
  //...
  getList: async ({
    resource,
    pagination,
    hasPagination,
    sort,
    filters,
    metaData,
  }) => {
    const headers = metaData?.headers ?? {};
    const url = `${apiUrl}/${resource}`;
    //...
    //...
    const { data, headers } = await httpClient.get(`${url}`, { headers });
    return {
      data,
    };
  },
  //...
};

dataProviderName​

If there is more than one dataProvider, you can specify which one to use by passing the dataProviderName prop. It is useful when you have a different data provider for different resources.

useAutocomplete({
  dataProviderName: "second-data-provider",
});

successNotification​

NotificationProvider is required for this prop to work.

After data is fetched successfully, useAutocomplete can call open function from NotificationProvider to show a success notification. With this prop, you can customize the success notification.

useAutocomplete({
  successNotification: (data, values, resource) => {
    return {
      message: `${data.title} Successfully fetched.`,
      description: "Success with no errors",
      type: "success",
    };
  },
});

errorNotification​

NotificationProvider is required for this prop to work.

After data fetching is failed, useAutocomplete will call open function from NotificationProvider to show a error notification. With this prop, you can customize the error notification.

useAutocomplete({
  errorNotification: (data, values, resource) => {
    return {
      message: `Something went wrong when getting ${data.id}`,
      description: "Error",
      type: "error",
    };
  },
});

liveMode​

LiveProvider is required for this prop to work.

Determines whether to update data automatically ("auto") or not ("manual") if a related live event is received. It can be used to update and show data in Realtime throughout your app. For more information about live mode, please check Live / Realtime page.

useAutocomplete({
  liveMode: "auto",
});

onLiveEvent​

LiveProvider is required for this prop to work.

The callback function that is executed when new events from a subscription are arrived.

useAutocomplete({
  onLiveEvent: (event) => {
    console.log(event);
  },
});

liveParams​

LiveProvider is required for this prop to work.

Params to pass to liveProvider's subscribe method.

FAQ​

How to ensure defaultValue is included in the options?​

In some cases we only have id, it may be necessary to show it selected in the selection box. This hook sends the request via useMany, gets the data and mark as seleted.

localhost:3000
Live previews only work with the latest documentation.
import {
    Autocomplete,
    useAutocomplete,
    TextField,
} from "@pankod/refine-mui";

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

const PostCreate: React.FC = () => {
    
    const { autocompleteProps } = useAutocomplete<ICategory>({
        resource: "categories",
        defaultValue: 11,
    });

    return (
        <Autocomplete
            {...autocompleteProps}
            getOptionLabel={(item) => item.title}
            isOptionEqualToValue={(option, value) =>
                value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()
            }
            placeholder="Select a category"
            renderInput={(params) => (
                <TextField
                    {...params}
                    label="Category"
                    margin="normal"
                    variant="outlined"
                    required
                />
            )}
        />
    );
};

Can I create the options manually?​

You can create a new options object with queryResult.

const { autocompleteProps, queryResult } = useAutocomplete();

const options = queryResult.data?.data.map((item) => ({
  title: item.title,
  value: item.id,
}));

return <Autocomplete {...autocompleteProps} options={options || []} />;

How do I use it with CRUD components and useForm?​

localhost:3000
Live previews only work with the latest documentation.
import {
    Create,
    Box,
    Autocomplete,
    useAutocomplete,
    TextField,
} from "@pankod/refine-mui";
import { useForm, Controller } from "@pankod/refine-react-hook-form";

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

const PostCreate: React.FC = () => {
    const {
        saveButtonProps,
        refineCore: { formLoading, queryResult },
        register,
        control,
        formState: { errors },
    } = useForm<IPost, HttpError, IPost & { category: ICategory }>();

    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={({ title }) => title}
                            isOptionEqualToValue={(option, value) =>
                                value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()
                            }
                            placeholder="Select a category"
                            renderInput={(params) => (
                                <TextField
                                    {...params}
                                    label="Category"
                                    margin="normal"
                                    variant="outlined"
                                    error={!!errors.category}
                                    helperText={errors.category?.message}
                                    required
                                />
                            )}
                        />
                    )}
                />
            </Box>
        </Create>
    );
};

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

INFORMATION

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.
