4. Adding Create Page
Create page is the page where you can create the record. In this tutorial, we will create the create page for the blog_posts
resource.
Creating 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:
Navigate to the localhost:3000/blog-posts in your browser.
To open the create page, click the "Create" button in the top right corner of the table.
On the create page, click on the "Show Code" button in the bottom right corner of the page.
You can see the create page code generated by Inferencer. Click on the "Copy" button to copy the code.
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.
Understanding the Create Component
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.useForm
hook, imported from@pankod/refine-react-hook-form
package, has been developed by using the React Hook Form anduseForm
hook imported from@pankod/refine-core
package.It provides all the features of the
useForm
hook from@pankod/refine-core
package as well as theuseForm
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 edit page,it sends the form data todataProvider
'screate
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 Material UI are used to display the form fields.
Refer to the Material UI documentation for more information →
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 useAutocomplete
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 <Autocomplete/>
component.
Refer to the useAutocomplete
documentation for more information →
Refer to the Material UI <Autocomplete/>
documentation for more information →
In the auto-generated create page code, Inferencer used the useAutocomplete
hook to select a category from the categories
resource like below:
const { selectProps: categorySelectProps } = useAutocomplete({
resource: "categories",
});
Adding the Create Page to the App
Now that we have created the create page, we need to add it to the App.tsx
file.
Open
src/App.tsx
file on your editor.Import the created
BlogPostCreate
component.Replace the
MuiInferencer
component with theBlogPostCreate
component.
import { Refine } from "@pankod/refine-core";
import {
Layout,
ReadyPage,
ErrorComponent,
LightTheme,
CssBaseline,
GlobalStyles,
ThemeProvider,
RefineSnackbarProvider,
useNotificationProvider,
} from "@pankod/refine-mui";
import routerProvider from "@pankod/refine-react-router-v6";
import dataProvider from "@pankod/refine-simple-rest";
import { MuiInferencer } from "@pankod/refine-inferencer/mui";
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: React.FC = () => {
return (
<ThemeProvider theme={LightTheme}>
<CssBaseline />
<GlobalStyles styles={{ html: { WebkitFontSmoothing: "auto" } }} />
<RefineSnackbarProvider>
<Refine
routerProvider={routerProvider}
dataProvider={dataProvider("https://api.fake-rest.refine.dev")}
notificationProvider={useNotificationProvider}
Layout={Layout}
ReadyPage={ReadyPage}
catchAll={<ErrorComponent />}
resources={[
{
name: "blog_posts",
list: BlogPostList,
edit: BlogPostEdit,
show: BlogPostShow,
create: BlogPostCreate,
},
]}
/>
</RefineSnackbarProvider>
</ThemeProvider>
);
};
export default App;
Now, we can see the create page in the browser at localhost:3000/blog-posts/create
