Laravel 9门“功能App\Providers\AuthServiceProvider::App\Providers\{closure}()...”的参数太少

Question

我有一个Evaluation模型，它与User有关系。我试图使用Laravel来保护评估路线，只允许指定的用户访问他们的评估。我以前从未使用过盖茨，也似乎无法让盖茨工作并不断地得到Too few arguments to function App\Providers\AuthServiceProvider::App\Providers\{closure}(), 1 passed in /Users/charles/Documents/Development/seedgen/vendor/laravel/framework/src/Illuminate/Auth/Access/Gate.php on line 536 and exactly 2 expected错误。我知道我需要提出更多的论点，但我被困住了。

AuthServiceProvidor.php

...
public function boot()
{
    $this->registerPolicies();

    Gate::define('showEval', function (User $user, Evaluation $evaluation) {
        return $user->id === $evaluation->user_id;
    });
}
...

Show.php

...
public function render()
{

    if (Gate::allows('showEval')) {
        return view('livewire.evaluation.show');
    } else {
        abort(403);
    }

}
...

Answer 1

你没有通过$evaluation来办理登机手续

public function render()
{
    // somehow getting $evaluation you want to pass to gate check
    if (Gate::allows('showEval', $evaluation)) {
        return view('livewire.evaluation.show');
    } else {
        abort(403);
    }

}

根据文档门本身获取当前用户，所以通过第二个param就在您身上。
