• Laravel Version: 9.45.1
• Nova Version: 4.19.5
• PHP Version: 8.1.10
• Database Driver & Version: MySQL
• Operating System and Version: 11
• Browser type and version: Firefox 108.0.1

Description:

When using the canSee function as describe in the document:
https://nova.laravel.com/docs/4.0/resources/authorization.html#fields

`
use Laravel\Nova\Fields\ID;
use Laravel\Nova\Fields\Text;

/**

• Get the fields displayed by the resource.

• @param \Laravel\Nova\Http\Requests\NovaRequest $request

• @return array
  */
  public function fields(NovaRequest $request)
  {
  return [
  ID::make()->sortable(),

   Text::make('Name')
           ->sortable()
           ->canSee(function ($request) {
               return $request->user()->can('viewProfile', $this);
           }),
  

  ];
  }
  `

it fired an error:
App\Policies\ModeNamePolicy::viwe(): Argument #2 ($modelName) must be of type App\Models\ModeName , App\Nova\ModeName given, called in ...\vendor\laravel\framework\src\Illuminate\Auth\Access\Gate.php on line 798

the function reun correctrly when us the function as:

Text::make('Name') ->sortable() ->canSee(function ($request) { return $request->user()->can('viewProfile', $this->resource); }),

This is not a bug. You can't pass a Nova resource to a Policy; it must be a Model instance.

As I mention the method that written in the document does not work for me,

Text::make('Name') ->sortable() ->canSee(function ($request) { return $request->user()->can('viewProfile', $this); }),

even the other way I was mistaken.
so what is the correct way to do it when i need to pass model to can?
right now I'm looking for the model that I need then pass it as:

$supply_contract = \App\Models\SupplyContract::find($request->resourceId);

SellsProductsTotal::make()->canSee(function ($request) use ($supply_contract) { return $request->user()->can('viewMetrics', $supply_contract); })->onlyOnDetail()

You would need to do this:

Text::make('Name') ->sortable() ->canSee(function ($request) {
    return $request->user()->can('viewProfile', $this->model());
}),

$this is the resource, $this->model() will provide the model if on the detail view of the page, but an empty model if on the index page.
