Fix create react admin fakerest

[djhi]

Problem

Fixes #10493

• create-react-admin ignore custom resources when using ra-data-fakerest
• The generated App.tsx file is incorrectly formatted:

import { Admin, Resource, ListGuesser, EditGuesser, ShowGuesser } from 'react-admin';
import { Layout } from './Layout';
import { dataProvider } from './dataProvider';


export const App = () => (
    <Admin
        layout={Layout}
        dataProvider={dataProvider}
        >
        <Resource name="books" list={ListGuesser} edit={EditGuesser} show={ShowGuesser} />
                <Resource name="authors" list={ListGuesser} edit={EditGuesser} show={ShowGuesser} />
    </Admin>
);

    

Solution

• Allow to override resources by specifying them using the CLI resource option
• Fix formatting
