Attempt to read property "model" on null.

I have a table that has a column "Briefcase" to show if the record (Business) belongs to a Briefcase. I'm implementing "->tooltip" to show to which User's Briefcase the Business belongs to.

Tables\Columns\TextColumn::make('briefcase.user.name')
    ->label('Briefcase')
    ->tooltip(fn (Business $record): string => "Business in " . $record->briefcase->user->name . "'s Briefcase"),

Tables\Columns\TextColumn::make('briefcase.user.name')
    ->label('Briefcase')
    ->tooltip(fn (Business $record): string => "Business in " . $record->briefcase->user->name . "'s Briefcase"),

The above "tooltip" code fails when one business is not allocated to any Briefcase, I get:

Attempt to read property "user" on null

Attempt to read property "user" on null

Please, any ideas how can I fix it? Thanks.

Use the nullsafe operator $record->briefcase?->user->name

or data_get($record, 'briefcase.user.name') https://laravel.com/docs/10.x/helpers#method-data-get

Nice, thank you for your help... Works. I have also tried your solution, also works. Now, I think this is better long time/maintenance. Also the "data_get" function accepts a default value which is nice and helpful. Thank you.

yep

You can pass a default via ?? 'default' $record->briefcase?->user->name ?? 'default' Embrace modern PHP 😅
