Issue with accessing data in React Admin Show Page using useRecordContext() function leads to undefined return

Within a basic RA application, I am attempting to showcase an item known as a "card" utilizing a Show Page. The fields—specifically id and title—are being presented correctly.

Nevertheless, the useRecordContext() hook is consistently returning undefined (similarly, useShowContext() and useShowController() were experimented with, as shown in the code below)—although I'm unable to determine the reason behind this issue.

The code within the ShowPage is outlined as follows:

// ./cards/CardShow.tsx
import { useParams } from 'react-router-dom';
import { useRecordContext, useShowContext, useShowController } from 'react-admin';
import { Show, SimpleShowLayout, TextField } from 'react-admin';

const CardShow = () => {
    const { id } = useParams();
    console.log(id);        // OK: displays the id
    
    const record = useRecordContext();
    console.log(record);    // ERROR: undefined
    
    const {isLoading, record:record2} = useShowContext();
    if(isLoading) {return null}
    console.log(record2);   // ERROR: null

    const { data } = useShowController();
    console.log(data);      // ERROR: undefined

    return (
        <Show>
            <SimpleShowLayout>
                {/* Displays correct data which 
                    proves somehow the record is fetched */}
                <TextField source="id" /> 
                <TextField source="title" />                
            </SimpleShowLayout>
        </Show>
    )
};
export default CardShow;

I have a suspicion that I might be overlooking something quite straightforward, yet pinpointing it has eluded me thus far... Any suggestions?

Your help is greatly appreciated!

Answer №1

Understood, for those who may be curious, the useRecordContext() function is only accessible below the Show component. Therefore, the code below now executes successfully:

import { useRecordContext } from 'react-admin';
import { Show, SimpleShowLayout, TextField } from 'react-admin';

const CustomLayout = () => {
    const record = useRecordContext();
    console.log(record); // it's working!
    return (
        <SimpleShowLayout>
            <TextField source="id" />
            <TextField source="name" />
        </SimpleShowLayout>
    )
}

const CustomShow = (
    <Show>
        <CustomLayout />
    </Show>
)
export default CustomShow;
