-The `<BooleanField>` component accept a generic type that describe the record. This is used to validate the `source` prop to ensure it targets an actual property of the record:
-
-```tsx
-import * as React from "react";
-import { Show, SimpleShowLayout, TextField, BooleanField, RichTextField } from 'react-admin';
-
-type Post = {
-    id: number;
-    title: string;
-    teaser: string;
-    body: string;
-    published: boolean;
-}
-
-export const PostShow = () => (
-    <Show>
-        <SimpleShowLayout>
-            <TextField<Post> source="title" />
-            <TextField<Post> source="teaser" />
-            <RichTextField<Post> source="body" />
-            <BooleanField<Post> source="published" />
-        </SimpleShowLayout>
-    </Show>
-);
-```

-Specifying the record type will also allow your IDE to provide auto-completion for both the `source` and `sortBy` prop. Note that the `sortBy` prop also accept any string.
