useStepsForm
useStepsForm allows you to manage a form with multiple steps. It provides features such as which step is currently active, the ability to go to a specific step and validation when changing steps etc.
信息
useStepsForm hook based on useForm hook provided by @pankod/refine-mantine.
Usage
We'll show two examples, one for creating and one for editing a post. Let's see how useStepsForm is used in both.
Let's create our <PostList> component to redirect to create and edit pages.
PostList
src/pages/posts/list.tsx
import React from "react";
import { useTable, ColumnDef, flexRender } from "@pankod/refine-react-table";
import {
List,
ScrollArea,
Table,
Pagination,
EditButton,
} from "@pankod/refine-mantine";
import { IPost } from "../../interfaces";
export const PostList: React.FC = () => {
const columns = React.useMemo<ColumnDef<IPost>[]>(
() => [
{
id: "id",
header: "ID",
accessorKey: "id",
},
{
id: "title",
header: "Title",
accessorKey: "title",
},
{
id: "status",
header: "Status",
accessorKey: "status",
},
{
id: "actions",
header: "Actions",
accessorKey: "id",
cell: function render({ getValue }) {
return (
<EditButton
hideText
size="xs"
recordItemId={getValue() as number}
/>
);
},
},
],
[],
);
const {
getHeaderGroups,
getRowModel,
refineCore: { setCurrent, pageCount, current },
} = useTable({
columns,
});
return (
<ScrollArea>
<List>
<Table highlightOnHover>
<thead>
{getHeaderGroups().map((headerGroup) => (
<tr key={headerGroup.id}>
{headerGroup.headers.map((header) => {
return (
<th key={header.id}>
{!header.isPlaceholder && (
<div>
{flexRender(
header.column.columnDef
.header,
header.getContext(),
)}
</div>
)}
</th>
);
})}
</tr>
))}
</thead>
<tbody>
{getRowModel().rows.map((row) => {
return (
<tr key={row.id}>
{row.getVisibleCells().map((cell) => {
return (
<td key={cell.id}>
{flexRender(
cell.column.columnDef.cell,
cell.getContext(),
)}
</td>
);
})}
</tr>
);
})}
</tbody>
</Table>
<br />
<Pagination
position="right"
total={pageCount}
page={current}
onChange={setCurrent}
/>
</List>
</ScrollArea>
);
};
Create Form
In this component you can see how useStepsForm is used to manage the steps and form.
src/pages/posts/create.tsx
import {
Button,
Code,
Create,
Group,
Select,
Stepper,
TextInput,
useStepsForm,
DatePicker,
RichTextEditor,
SaveButton,
Text,
} from "@pankod/refine-mantine";
export const PostCreate: React.FC = () => {
const {
saveButtonProps,
getInputProps,
values,
steps: { currentStep, gotoStep },
} = useStepsForm({
initialValues: {
title: "",
status: "",
slug: "",
createdAt: new Date(),
content: "",
},
validate: (values) => {
// validation for each step
if (currentStep === 0) {
return {
title: values.title ? null : "Title is required",
slug: values.slug ? null : "Slug is required",
};
}
if (currentStep === 1) {
return {
status: values.status ? null : "Status is required",
createdAt: values.createdAt
? null
: "CreatedAt is required",
};
}
return {};
},
});
return (
<Create
// Next, previous and save buttons
footerButtons={
<Group position="right" mt="xl">
{currentStep !== 0 && (
<Button
variant="default"
onClick={() => gotoStep(currentStep - 1)}
>
Back
</Button>
)}
{currentStep !== 3 && (
<Button onClick={() => gotoStep(currentStep + 1)}>
Next step
</Button>
)}
{currentStep === 2 && <SaveButton {...saveButtonProps} />}
</Group>
}
>
<Stepper active={currentStep} breakpoint="sm">
<Stepper.Step label="First Step">
<TextInput
mt="md"
label="Title"
placeholder="Title"
{...getInputProps("title")}
/>
<TextInput
mt="md"
label="Slug"
placeholder="Slug"
{...getInputProps("slug")}
/>
</Stepper.Step>
<Stepper.Step label="Second Step">
<Select
mt="md"
label="Status"
placeholder="Pick one"
{...getInputProps("status")}
data={[
{ label: "Published", value: "published" },
{ label: "Draft", value: "draft" },
{ label: "Rejected", value: "rejected" },
]}
/>
<DatePicker
mt="md"
label="CreatedAt"
placeholder="CreatedAt"
{...getInputProps("createdAt")}
/>
</Stepper.Step>
<Stepper.Step label="Final Step">
<Text mt={8} weight={500} size="sm" color="#212529">
Content
</Text>
<RichTextEditor
sx={{ minHeight: 300 }}
{...getInputProps("content")}
/>
</Stepper.Step>
<Stepper.Completed>
Completed! Form values:
<Code block mt="xl">
{JSON.stringify(values, null, 2)}
</Code>
</Stepper.Completed>
</Stepper>
</Create>
);
};
Edit Form
Magic, <PostCreate> and <PostEdit> pages are almost the same. So how are the form's default values set? useStepsForm does this with te id parameter it reads from the URL and fetches the data from the server.
You can change the id as you want with the setId that comes out of refineCore.
Another part that is different from <PostCreate> and <PostEdit> is the value passed to the DatePicker component.
src/pages/posts/edit.tsx
import {
Button,
Code,
Edit,
Group,
Select,
Stepper,
TextInput,
useStepsForm,
DatePicker,
RichTextEditor,
SaveButton,
Text,
} from "@pankod/refine-mantine";
import dayjs from "dayjs";
export const PostEdit: React.FC = () => {
const {
saveButtonProps,
getInputProps,
values,
steps: { currentStep, gotoStep },
} = useStepsForm({
initialValues: {
title: "",
status: "",
slug: "",
createdAt: new Date(),
content: "",
},
validate: (values) => {
// validation for each step
if (currentStep === 0) {
return {
title: values.title ? null : "Title is required",
status: values.status ? null : "Status is required",
};
}
if (currentStep === 1) {
return {
slug: values.slug ? null : "Slug is required",
createdAt: values.createdAt
? null
: "CreatedAt is required",
};
}
return {};
},
});
return (
<Edit
// Next, previous and save buttons
footerButtons={
<Group position="right" mt="xl">
{currentStep !== 0 && (
<Button
variant="default"
onClick={() => gotoStep(currentStep - 1)}
>
Back
</Button>
)}
{currentStep !== 3 && (
<Button onClick={() => gotoStep(currentStep + 1)}>
Next step
</Button>
)}
{currentStep === 2 && <SaveButton {...saveButtonProps} />}
</Group>
}
