3. Adding Show Page

Creating the Show Page

First, we need to create our file, named show.tsx, under the src/pages/blog-posts folder. We will then copy the show page code generated by Inferencer and paste it into the file; for this, follow these steps:

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

  2. Click on any of the "Show" buttons in the "Actions" column of the table to open the edit page.

  3. 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. Copy it by clicking on the "Copy" button.

  5. Paste the code into the newly created show.tsx file.

You can see an example show page generated by Inferencer below:


Understanding the Show Component

Hooks and Components in Show Page

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

    For more information, refer to the <Show/> documentation

  • The useShow hook 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.

    For more information, refer to the useShow documentation#8594

Handling Relationships

On the show page, we have a single record, and it 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, which allows us to fetch single record data by using the id and resource parameters.

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

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

To ensure that the related data is fetched only 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, just like below:

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

For more information, refer to the useOne documentation

Adding the Show Page to the App

Now that we have created the show page, we can 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 AntdInferencer component with the BlogPostShow component.

import {
} from "@refinedev/antd";
import { Refine } from "@refinedev/core";
import { AntdInferencer } from "@refinedev/inferencer/antd";
import routerBindings, {
} from "@refinedev/react-router-v6";
import dataProvider from "@refinedev/simple-rest";

import { BrowserRouter, Outlet, Route, Routes } from "react-router-dom";

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

import "@refinedev/antd/dist/reset.css";

const App: React.FC = () => {
return (
name: "blog_posts",
list: "/blog-posts",
show: "/blog-posts/show/:id",
create: "/blog-posts/create",
edit: "/blog-posts/edit/:id",
syncWithLocation: true,
warnWhenUnsavedChanges: true,
<Outlet />
<NavigateToResource resource="blog_posts" />

<Route path="blog-posts">
<Route index element={<BlogPostList />} />
<Route path="show/:id" element={<BlogPostShow />} />
<Route path="edit/:id" element={<BlogPostEdit />} />
<Route path="create" element={<AntdInferencer />} />

<Route path="*" element={<ErrorComponent />} />
<UnsavedChangesNotifier />

export default App;

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