middleware内でバリデーションが可能に

namespace App\Http\Middleware;

class CheckRequiredParameters
{
    public function handle(Request $request, Closure $next)
    {
         $rules = [
              ‘user_id' => 'required',
         1;

         $request->validate($rules);

         return $next($request);
    }
}

middlewareに引数渡せる

Route::get('/success-diary', ShowSuccessDiaryController::class)
        ->middleware('onboarding:SuccessDiary.Onboarding' )
        ->name('success-diary. index' )

class ShowOnboardingScreen
{
    // $viewにSuccessDiary.Onboardingが入っていると思う
    public function handle(Request $request, Closure $next, string $view)
    {
         if (! $request->user()->sawOnboardingScreen($view)) {

            $request->user()->markOnboardingScreenAsSeen($view) ;

            return Inertia::render(str_replace('.', '/', $view));
        }

        return $next($request);
    }
}

もし、Eloquentがカスタムコレクションクラスを返すようにしたい場合は、モデルで newCollection メソッドを使用します。

class Invoice extends Eloquent
{
    public function newCollection(array $models = [])
    {
         return new InvoiceCollection($models);
    }
}

Eloquentのモデルでは、他のリレーションの最新（または最古）の項目を取得するリレーションを定義することができます。

public function historyItems(): HasMany
{
    return $this
        ->hasMany (ApplicationHealthCheckHistoryItem::class)
        ->orderByDesc('created_at');
}


public function LatestHistoryItem(): HasOne
{
    return $this
        ->hasOne(ApplicationHealthCheckHistoryItem: : class)
        ->latestOfMany();
}

this package can be used to monitor the health of your Laravel application.

example

class HealthServiceProvider extends ServiceProvider
{
    public function register()
    {
        Health::checks([
            CpuLoadCheck::new()->failWhenLoadIsHigherInTheLast5Minutes(2.0),
            DebugModeCheck::new(),
            EnvironmentCheck::new(),
            DatabaseCheck::new(),
            HorizonCheck::new(),
            UsedDiskSpaceCheck::new()
                ->warnWhenUsedSpaceIsAbovePercentage(90)
                ->failWhenUsedSpaceIsAbovePercentage(95),
            ScheduleCheck::new()->heartbeatMaxAgeInMinutes(2),
            FlareErrorOccurrenceCountCheck::new()
                ->projectId(config('services.flare.project_id'))
                ->apiToken(config('services.flare.api_token'))
        ]);
    }
}

以下２つは同じふるまい

$query->tap(fn ($query) => match (request('sort')) {
   ‘category' => $query->orderByCategory(),
   'last_comment' => $query->orderByLastCommentDate(),
   'status' => $query->orderByStatus(),
   'activity' => $query->orderByActivity(),
   default => $query->orderByName(),
);

$query->when(Request::input('sort'), Gunction ($query, $sort) {
    Switch ($sort) 
        case 'category': return $query->orderByCategory();
        case 'last_comment': return $query->orderByLastCommentDate();
        case 'status': return $query->orderByStatus();
        case ‘activity’: return $query->orderByActivity();
    3
}, gunction ($query) {
    $query->orderByName();
});

$request->whenFilled('name', function ($input) {
    // "name"の値が空でない場合の処理…
}, function () {
    // "name"の値が空の場合の処理…
});
