useModalForm

useModalForm hook also allows you to manage a form inside a modal component. It provides some useful methods to handle the form modal.

useModalForm hook is extended from useForm hook from the @refinedev/mantine package. This means that you can use all the features of useForm hook.

Usage​

We will show three examples, "create", "edit" and "clone". Let's see how useModalForm is used in all.

In this example, we will show you how to "create" a record with useModalForm:

localhost:3000/posts
import {
  Box,
  Group,
  Modal,
  Pagination,
  ScrollArea,
  Select,
  Table,
  TextInput,
} from "@mantine/core";
import { List, SaveButton, useModalForm } from "@refinedev/mantine";
import { useTable } from "@refinedev/react-table";
import { ColumnDef, flexRender } from "@tanstack/react-table";
import React from "react";

const PostList: React.FC = () => {
  const {
    getInputProps,
    saveButtonProps,
    modal: { show, close, title, visible },
  } = useModalForm({
    refineCoreProps: { action: "create" },
    initialValues: {
      title: "",
      status: "",
      content: "",
    },
    validate: {
      title: (value) => (value.length < 2 ? "Too short title" : null),
      status: (value) => (value.length <= 0 ? "Status is required" : null),
    },
  });

  const columns = React.useMemo<ColumnDef<IPost>[]>(
    () => [
      {
        id: "id",
        header: "ID",
        accessorKey: "id",
      },
      {
        id: "title",
        header: "Title",
        accessorKey: "title",
        meta: {
          filterOperator: "contains",
        },
      },
      {
        id: "status",
        header: "Status",
        accessorKey: "status",
        meta: {
          filterElement: function render(props: FilterElementProps) {
            return (
              <Select
                defaultValue="published"
                data={[
                  { label: "Published", value: "published" },
                  { label: "Draft", value: "draft" },

                ]}
                {...props}
              />
            );
          },
          filterOperator: "eq",
        },
      },
    ],
    [],
  );

  const {
    getHeaderGroups,
    getRowModel,
    setOptions,
    refineCore: {
      setCurrent,
      pageCount,
      current,
      tableQuery: { data: tableData },
    },
  } = useTable({
    columns,
  });

Properties​

refineCoreProps​

All useForm properties are also available in useStepsForm. You can find descriptions on useForm documentation.

const modalForm = useModalForm({
  refineCoreProps: {
    action: "edit",
    resource: "posts",
    id: "1",
  },
});

initialValues​

Default values for the form. Use this to pre-populate the form with data that needs to be displayed. This property is only available for "create" action.

const modalForm = useModalForm({
  initialValues: {
    title: "Hello World",
  },
});

defaultVisible​

When true, modal will be visible by default. It is false by default.

const modalForm = useModalForm({
  modalProps: {
    defaultVisible: true,
  },
});

autoSubmitClose​

When true, modal will be closed after successful submit. It is true by default.

const modalForm = useModalForm({
  modalProps: {
    autoSubmitClose: false,
  },
});

autoResetForm​

When true, form will be reset after successful submit. It is true by default.

const modalForm = useModalForm({
  modalProps: {
    autoResetForm: false,
  },
});

syncWithLocation​

When true, the modals visibility state and the id of the record will be synced with the URL. It is false by default.

This property can also be set as an object { key: string; syncId?: boolean } to customize the key of the URL query parameter. id will be synced with the URL only if syncId is true.

const modalForm = useModalForm({
  syncWithLocation: { key: "my-modal", syncId: true },
});

overtimeOptions​

If you want loading overtime for the request, you can pass the overtimeOptions prop to the this hook. It is useful when you want to show a loading indicator when the request takes too long. interval is the time interval in milliseconds. onInterval is the function that will be called on each interval.

Return overtime object from this hook. elapsedTime is the elapsed time in milliseconds. It becomes undefined when the request is completed.

const { overtime } = useModalForm({
  //...
  overtimeOptions: {
    interval: 1000,
    onInterval(elapsedInterval) {
      console.log(elapsedInterval);
    },
  },
});

console.log(overtime.elapsedTime); // undefined, 1000, 2000, 3000 4000, ...

// You can use it like this:
{
  elapsedTime >= 4000 && <div>this takes a bit longer than expected</div>;
}

autoSave​

If you want to save the form automatically after some delay when user edits the form, you can pass true to autoSave.enabled prop.

By default the autoSave feature does not invalidate queries. However, you can use the invalidateOnUnmount and invalidateOnClose props to invalidate queries upon unmount or close.

It also supports onMutationSuccess and onMutationError callback functions. You can use isAutoSave parameter to determine whether the mutation is triggered by autoSave or not.

autoSave feature operates exclusively in edit mode. Users can take advantage of this feature while editing data, as changes are automatically saved in editing mode. However, when creating new data, manual saving is still required.

onMutationSuccess and onMutationError callbacks will be called after the mutation is successful or failed.

enabled​

To enable the autoSave feature, set the enabled parameter to true. Default value is false.

useModalForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
    },
  },
});

debounce​

Set the debounce time for the autoSave prop. Default value is 1000 milliseconds.

useModalForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
      debounce: 2000,
    },
  },
});

invalidateOnUnmount​

This prop is useful when you want to invalidate the list, many and detail queries from the current resource when the hook is unmounted. By default, it invalidates the list, many and detail queries associated with the current resource. Also, You can use the invalidates prop to select which queries to invalidate. Default value is false.

useModalForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
      invalidateOnUnmount: true,
    },
  },
});

invalidateOnClose​

This prop is useful when you want to invalidate the list, many and detail queries from the current resource when the modal is closed. By default, it invalidates the list, many and detail queries associated with the current resource. Also, You can use the invalidates prop to select which queries to invalidate. Default value is false.

useModalForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
      invalidateOnClose: true,
    },
  },
});

Return Values​

All useForm return values also available in useModalForm. You can find descriptions on useForm docs.

All mantine useForm return values also available in useModalForm. You can find descriptions on mantine docs.

FAQ​

How can I change the form data before submitting it to the API?​

You may need to modify the form data before it is sent to the API.

For example, let's send the values we received from the user in two separate inputs, name and surname, to the API as fullName.

pages/user/create.tsx
import React from "react";
import { useModalForm } from "@refinedev/mantine";
import { TextInput, Modal } from "@mantine/core";

const UserCreate: React.FC = () => {
    const {
        getInputProps,
        saveButtonProps,
        modal: { show, close, title, visible },
    } = useModalForm({
        refineCoreProps: { action: "create" },
        initialValues: {
            name: "",
            surname: "",
        },
        transformValues: (values) => ({
            fullName: `${values.name} ${values.surname}`,
        }),
    });

    return (
        <Modal opened={visible} onClose={close} title={title}>
            <TextInput
                mt={8}
                label="Name"
                placeholder="Name"
                {...getInputProps("name")}
            />
            <TextInput
                mt={8}
                label="Surname"
                placeholder="Surname"
                {...getInputProps("surname")}
            />
            <Box mt={8} sx={{ display: "flex", justifyContent: "flex-end" }}>
                <Button
                    {...saveButtonProps}
                    onClick={(e) => {
                        // -- your custom logic
                        saveButtonProps.onClick(e);
                    }}
                />
