    2. Adding Edit Page

    Edit page is the page where you can edit the record. In this tutorial, we will create the edit page for the blog_posts resource.

    Creating Edit Page

    First, let's create our file under the src/pages/blog-posts folder. We will name it edit.tsx. Then, we will copy the edit page code generated by Inferencer and paste it into the file.

    To copy the code and paste it into the file, follow the steps below:

    1. Navigate to the localhost:3000/blog-posts in your browser.

    2. To open the edit page, click any "Edit" button in the "Actions" column of the table.

    3. On the edit page, click on the "Show Code" button in the bottom right corner of the page.

    4. You can see the edit page code generated by Inferencer. Click on the "Copy" button to copy the code.

    5. Paste the code into the you created, edit.tsx file.

    You can see the edit page code generated by Inferencer below:

    Live previews only work with the latest documentation.

    Instead of coding the edit page component from scratch, Inferencer created the required code base on API response, so that we can customize.

    Understanding the Edit Component

    We will go through the edit page components and hooks one by one.

    Handling Relationships

    In the edit page, we may need to select a record from another resource. For example, we may need to select a category from the categories resource to assign the blog post to the category. In this case, we can use the useSelect hook provided by refine. This hook fetches the data by passing the params to the dataProvider's getList method. Then, it returns the necessary props for the <Select/> component.

    Refer to the useSelect documentation for more information

    Refer to the Mantine <Select/> documentation for more information

    In the auto-generated edit page code, Inferencer used the useSelect hook to select a category from the categories resource like below:

    const { selectProps: categorySelectProps } = useSelect({
    resource: "categories",

    useSelect returns 10 record by default, but the category of the blog post may not be in the first 10 records. To solve this problem, we can use the defaultValue prop to set the default value of the useSelect hook like below:

    const { selectProps: categorySelectProps } = useSelect({
    resource: "categories",
    defaultValue: blogPostsData?.category?.id,

    Adding the Edit Page to the App

    Now that we have created the edit page, we need to add it to the App.tsx file.

    1. Open src/App.tsx file on your editor.

    2. Import the created BlogPostEdit component.

    3. Replace the MantineInferencer component with the BlogPostEdit component.

    import { Refine } from "@pankod/refine-core";
    import routerProvider from "@pankod/refine-react-router-v6";
    import dataProvider from "@pankod/refine-simple-rest";
    import {
    } from "@pankod/refine-mantine";
    import { MantineInferencer } from "@pankod/refine-inferencer/mantine";

    import { BlogPostList } from "pages/blog-posts/list";
    import { BlogPostEdit } from "pages/blog-posts/edit";

    const App = () => {
    return (
    <MantineProvider theme={LightTheme} withNormalizeCSS withGlobalStyles>
    <Global styles={{ body: { WebkitFontSmoothing: "auto" } }} />
    <NotificationsProvider position="top-right">
    catchAll={<ErrorComponent />}
    name: "blog_posts",
    list: BlogPostList,
    edit: BlogPostEdit,
    edit: MantineInferencer,
    show: MantineInferencer,
    create: MantineInferencer,
    export default App;

    Now, we can see the edit page in the browser at localhost:3000/blog-posts/edit/123
