如何在Laravel授权中将数字传递给中间件“can”

Question

based on documentation https://laravel.com/docs/5.5/authorization#via-middleware

use App\Post;

Route::put('/post/{post}', function (Post $post) {
    // The current user may update the post...
})->middleware('can:update,post');

the 'post' in 'can:update,post' is variable passed from '{post}'.

im trying to use middleware('can:update,1'). its not working. maybe its search for '$1' variable, how to pass number '1' to 'can' middleware?

update this is the gate:

    Gate::define('update', function ($user, $role){
        $id = $user->id;
        $roles = $user::find($id)->roles()->get();
        $roleid = $roles[0]->pivot->role_id;
        //above code just for get role id, and $role_id is 1
       return $roleid === $role;
    });

Probably you don't have Policy created for Post.

You can create by command:

php artisan make:policy PostPolicy --model=Post

and then implement method update in that policy.
