Using Gates in Laravel 11 for view functionality

I'm trying to get a gate in Laravel 11 to show only the income for the particular user. I am not sure what condition to pass to the gate. I am using the example from Laravel docs for update, but this is still passing all the data to the vue page.

This is in AppServiceProvider.php:

    public function boot(): void
    {
        Gate::define('view-income', function (User $user, Income $income) {
            return $user->id === $income->user_id;
        });
    }

And this is FinancesController.php:

class FinancesController extends Controller
{
    public function index(User $user, Income $income)
    {
        if(!Gate::allows('view-income', $income)) {
            return inertia(
                'Finances/FinancesMain',
                [
                    'incomes' => Income::all(),
                ]
            );
        }
    }
}

If I toggle between "!" and removing "!", it will either pass all the data or none of the data. I'm trying to get it only to pass data for a certain userid. I'm not sure what condition to pass to the gate. If I use

  'incomes' => Income::all()->where('user_id', $id),

there's not much point in having a gate.

Any help would be appreciated.

It may be a misunderstanding about Gates.

In general, it's supposed to control who is allowed to access something.

Gates can be used to return data, but usually, the answer will be only a bool to define whether someone can access something.

The way to implement it will depend on your logic. let's imagine you have 2 levels of users: admin and normal, admin users can see all data but normal users can only see itself data. The code can be something like that:

if (Gate::allows('admin')) {
  $data = Income::all();
} else {
  $data = Income::all()->where('user_id', $id);
}

return inertia(
  'Finances/FinancesMain',
    [
      'incomes' => $data,
    ]
);

PS.

As you're using === please ensure both data types are equal.
