External images. Location stored in json column

Not sure what you're asking. Are you trying to extract the thumb from the JSON?

$data = json_decode($JSON);
$thumb = $json->thumb;

Or...not sure what you're asking for.

1. Table with urls column woth format json.
2. Nova
3. Extract URL from urls (thumb)
4. Aply this how image image in list of resource photo, such image

My code with nova:

use Laravel\Nova\Fields\ID;
use Laravel\Nova\Fields\Text;
use R64\NovaFields\JSON;
use Chaseconey\ExternalImage\ExternalImage;

public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),
            Text::make('Unsplash','unsplash_id'),
            Text::make('Title', 'description'),
            ExternalImage::make('Image')
                ->prefix(function () {
                    $data = json_decode($this->urls);
                    return $data->thumb;
                })
        ];
    }

But fails

Argument 1 passed to Chaseconey\ExternalImage\ExternalImage::prefix() must be of the type string, object given, called in /Users/abkrim/Sites/multimedia/app/Nova/Photo.php on line 55 {"userId":1,"email":"[email protected]","exception":"[object] (Symfony\Component\Debug\Exception\FatalThrowableError(code: 0): Argument 1 passed to Chaseconey\ExternalImage\ExternalImage::prefix() must be of the type string, object given, called in /Users/abkrim/Sites/multimedia/app/Nova/Photo.php on line 55 at /Users/abkrim/Sites/multimedia/vendor/chaseconey/nova-external-image/src/ExternalImage.php:24)

If use this

    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),
            Text::make('Unsplash','unsplash_id'),
            Text::make('Title', 'description'),
//            ExternalImage::make('Image')
//                ->prefix(function () {
//                    $data = json_decode($this->urls);
//                    return $data->thumb;
//                })
            Text::make('url', function () {
                    $data = json_decode($this->urls);
                    return $data->thumb;
                })
        ];
    }

I see text of link, but I like code for see an image.

Best regards.

Well, after some ideas I get solution.

...
use Chaseconey\ExternalImage\ExternalImage;
...

public function fields(Request $request)
{
    return [
        ID::make()->sortable(),
        Text::make('Unsplash','unsplash_id'),
        Text::make('Title', 'description'),

        ExternalImage::make('Image', 'url_regular')

    ];
}

In my model Photo

...
public function getUrlRegularAttribute()
{
    $data = json_decode($this->urls);
    return "{$data->regular}";
}

public function getUrlThumbAttribute()
{
    $data = json_decode($this->urls);
    //$uri = str_replace('https://images.unsplash.com/', '', $data->thumb);
    //return "{$uri}";
    return "{$data->thumb}";
}
