3. Adding Show Page

First, let's create our file under the src/pages/blog-posts folder. We will name it show.tsx. Then, we will copy the show 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 show page, click any "Show" button in the "Actions" column of the table.

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

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

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

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

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

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

• <Show/> is a refine component that is used to presentation purposes like showing the title of the page, list button, etc.

  Refer to the <Show/> documentation for more information →

• useShow is a refine hook that is used to get single record data by using the id in the URL. It sends the parameters to the dataProvider's getOne function and returns the result.

  Refer to the useShow documentation for more information →

• All other components are Chakra UI components that are used to show the record data.

  Refer to the Chakra UI documentation for more information →

In the show page, we have a single record. The record may have relationships with other resources.

For example, the blog_posts resource has a relationship with the categories resource. In this case, we can use the useOne hook provided by refine. This hook allows us to fetch single record data by using the id and resource parameters.

Refer to the useOne documentation for more information →

In the auto-generated show page code, Inferencer used the useOne hook to fetch the category data of the blog post record.

const { data: categoryData, isLoading: categoryIsLoading } = useOne({
  resource: "categories",
  id: record?.category?.id || "",
});

To ensure that the related data is only fetched after the blog post record has been successfully retrieved, we can use the queryOptions object. By setting the enabled property to true only if the record variable is truthy, we can control when the related data is fetched like below:

const { data: categoryData, isLoading: categoryIsLoading } = useOne({
  resource: "categories",
  id: record?.category?.id || "",
  queryOptions: {
    enabled: !!record,
  },
});

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

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

2. Import the created BlogPostShow component.

3. Replace the ChakraUIInferencer component with the BlogPostShow component.

import { Refine } from "@pankod/refine-core";
import routerProvider from "@pankod/refine-react-router-v6";
import dataProvider from "@pankod/refine-simple-rest";
import {
  ChakraProvider,
  ErrorComponent,
  Layout,
  refineTheme,
  ReadyPage,
  useNotificationProvider,
} from "@pankod/refine-chakra-ui";
import { ChakraUIInferencer } from "@pankod/refine-inferencer/chakra-ui";

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

const App = () => {
  return (
    <ChakraProvider theme={refineTheme}>
      <Refine
        notificationProvider={notificationProvider()}
        routerProvider={routerProvider}
        dataProvider={dataProvider("https://api.fake-rest.refine.dev")}
        Layout={Layout}
        ReadyPage={ReadyPage}
        catchAll={<ErrorComponent />}
        resources={[
          {
            name: "blog_posts",
            list: BlogPostList,
            edit: BlogPostEdit,
            show: BlogPostShow,
            create: ChakraUIInferencer,
          },
        ]}
      />
    </ChakraProvider>
  );
};
export default App;

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