4. Adding Create Page

First, let's create our file under the src/pages/blog-posts folder. We will name it create.tsx. Then, we will copy the create 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 create page, click the "Create" button in the top right corner of the table.

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

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

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

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

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

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

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

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

• useForm hook, imported from @pankod/refine-react-hook-form package, has been developed by using the React Hook Form and useForm hook imported from @pankod/refine-core package.

  It provides all the features of the useForm hook from @pankod/refine-core package as well as the useForm hook from React Hook Form.

  It also provides the saveButtonProps prop that we can pass to the submit button of the form.

  When you use useForm in the create page, it sends the form data to dataProvider's create method when the form is submitted.

  Refer to the @pankod/refine-react-hook-form useForm documentation for more information →

  Refer to the React Hook Form documentation for more information →

• All other components provided by Chakra UI are used to display the form fields.

  Refer to the Chakra UI documentation for more information →

In the create 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 resource name to the dataProvider's getList method. Then, it returns the options to be used in the <Select/> component.

Refer to the useSelect documentation for more information →

Refer to the Chakra UI <Select/> documentation for more information →

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

const { options: categoryOptions } = useSelect({
  resource: "categories",
});

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

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

2. Import the created BlogPostCreate component.

3. Replace the ChakraUIInferencer component with the BlogPostCreate 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";
import { BlogPostCreate } from "pages/blog-posts/create";

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: BlogPostCreate,
          },
        ]}
      />
    </ChakraProvider>
  );
};
export default App;

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