laravel authorization ability check too few arguments

Question

blade:

@can('see_similar', $similar, $in_pair)
...
@endcan

class AuthServiceProvider extends ServiceProvider:

public function boot()
{
    $this->registerPolicies();
    Gate::define('see_similar', function ($user, $similar, $in_pair) {
        return count($similar) > 0 && (isset($in_pair)) && $in_pair !== 'in_pair';
    });
}

It gives me this error:

Too few arguments to function App\Providers\AuthServiceProvider::App\Providers{closure}(), 2 passed in /var/www/html/vendor/laravel/framework/src/Illuminate/Auth/Access/Gate.php on line 452 and exactly 3 expected (View: /var/www/html/resources/views/daters.blade.php)

Though it works if I pass just one argument "...function($user, $similar)" for example. I tried to pass an array of args, didn't work.

Please explain to me how can I pass several arguments.

From the doc:

Gates always receive a user instance as their first argument, and may optionally receive additional arguments such as a relevant Eloquent model

Your problem is that you are passing 3 parameters to the closure function, you need to remove one.

public function boot()
{
    $this->registerPolicies();
    // Here you MUST pass at most 2 parameters
    Gate::define('see_similar', function ($user, $ELOQUENT_MODEL) {
        return $what_you_want; // A boolean value
    });
}
