Laravel Nova authorization using Policy is not working

Question

I am developing a web application using Laravel. I am using Nova for admin panel. What I am doing now is I am authorizing my resource using policies as mentioned in the documentation. But seems like it is not working. This is what I have done so far. I have created a nova resource like this.

class Item extends Resource
{
    /**
     * The model the resource corresponds to.
     *
     * @var string
     */
    public static $model = \App\Models\Item::class;

    /**
     * The single value that should be used to represent the resource when being displayed.
     *
     * @var string
     */
    public static $title = 'id';

    /**
     * The columns that should be searched.
     *
     * @var array
     */
    public static $search = [
        'id',
    ];

    /**
     * Get the fields displayed by the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),
        ];
    }

    /**
     * Get the cards available for the request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function cards(Request $request)
    {
        return [];
    }

    /**
     * Get the filters available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function filters(Request $request)
    {
        return [];
    }

    /**
     * Get the lenses available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function lenses(Request $request)
    {
        return [];
    }

    /**
     * Get the actions available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function actions(Request $request)
    {
        return [];
    }
}

Then I created a Laravel Model class for that resource with the name Item.

Then I created policy.

class ItemPolicy
{
    use HandlesAuthorization;

    public function viewAny(User $user)
    {
        return true;
    }

    public function view(User $user, $item)
    {
        return true;
    }


    public function create(User $user)
    {
        return false;
    }

    public function update(User $user, $item)
    {

        return false;
    }

    public function delete(User $user, $item)
    {
        return false;
    }

    public function restore(User $user, $item)
    {
        return false;
    }

    public function forceDelete(User $user, $item)
    {
        return false;
    }
}

I register the policy in the in AuthServiceProvider.

protected $policies = [

    Item::class => ItemPolicy::class,
];

When I see the list of item in the nova admin panel, I can still create the item. What is wrong? The option for creating an item should be hidden.

Answer 1

Add the following to your Nova resource class:

public static function authorizable()
{
    return true;
}

Answer 2

Check AuthServiceProvider once again.

where you define the policy mapping array:

protected $policies = [
    Item::class => ItemPolicy::class,
];

The Item - should be your Model, not Nova Resource
