<CreateBase>
<CreateBase> is a headless variant of <Create>. It prepares a form submit handler, and renders its children in a CreateContext. Use it to build a custom creation page layout.
Contrary to <Create>, it does not render the page layout, so no title, no actions, and no <Card>.
<CreateBase> relies on the useCreateController hook.
Usage
Use <CreateBase> to create a custom Creation view, with exactly the content you add as child and nothing else (no title, Card, or list of actions as in the <Create> component).
import * as React from "react";
import { CreateBase, SimpleForm, TextInput, SelectInput } from "react-admin";
import { Card } from "@mui/material";
export const BookCreate = () => ( 
    <CreateBase>
        <div>
            <Title title="Book Creation" />
            <Card>
                <SimpleForm>
                    <TextInput source="title" />
                    <TextInput source="author" />
                    <SelectInput source="availability" choices={[
                        { id: "in_stock", name: "In stock" },
                        { id: "out_of_stock", name: "Out of stock" },
                        { id: "out_of_print", name: "Out of print" },
                    ]} />
                </SimpleForm>
            </Card>
        </div>
    </CreateBase>
);
Props
You can customize the <CreateBase> component using the following props, documented in the <Create> component:
- children: the components that renders the form
- disableAuthentication: disable the authentication check
- mutationOptions: options for the- dataProvider.create()call
- record: initialize the form with a record
- redirect: change the redirect location after successful creation
- resource: override the name of the resource to create
- transform: transform the form data before calling- dataProvider.create()
Security
The <CreateBase> component requires authentication and will redirect anonymous users to the login page. If you want to allow anonymous access, use the disableAuthentication prop.
If your authProvider implements Access Control, <CreateBase>  will only render if the user has the βcreateβ access to the related resource.
For instance, for the <PostCreate>page below:
import { CreateBase, SimpleForm, TextInput } from 'react-admin';
// Resource name is "posts"
const PostCreate = () => (
    <CreateBase>
        <SimpleForm>
            <TextInput source="title" />
            <TextInput source="author" />
            <TextInput source="published_at" />
        </SimpleForm>
    </CreateBase>
);
<CreateBase> will call authProvider.canAccess() using the following parameters:
{ action: "create", resource: "posts" }
Users without access will be redirected to the Access Denied page.
Note: Access control is disabled when you use the disableAuthentication prop.
