編集画面の作成
1. sail artisan make:controller Tweet/Update/IndexController --invokable
namespace App\Http\Controllers\Tweet\Update;
use App\Http\Controllers\Controller;
use App\Models\Tweet;
use Illuminate\Http\Request;
class IndexController extends Controller
{
/**
* Handle the incoming request.
*/
public function __invoke(Request $request): View
{
return view('tweet.update', ['tweet' => Tweet::where('id', (int)$request->route('id'))->firstOrFail()]);
}
}2. route/web.phpに追加
Route::get('/tweet/update/{id}', \App\Http\Controllers\Tweet\Update\IndexController::class)->name('tweet.update.index')->where('id', '[0-9]+');
3. touch resources/views/tweet/update.blade.php

1. sail artisan make:controller Tweet/Update/PutController --invokable
<?php
namespace App\Http\Controllers\Tweet\Update;
use App\Http\Controllers\Controller;
use App\Http\Requests\Tweet\UpdateRequest;
use App\Models\Tweet;
use App\Services\TweetService;
use Symfony\Component\HttpFoundation\File\Exception\AccessDeniedException;
use Symfony\Component\HttpFoundation\Response;
class PutController extends Controller
{
/**

*/
public function __invoke(UpdateRequest $request, TweetService $tweetService): Response
{
if (!$tweetService->isOwnTweet($request->user()->id, $request->id())) {
throw new AccessDeniedException();
}
$tweet = Tweet::where('id', $request->id())->firstOrFail();
$tweet->content = $request->tweet();
$tweet->save();
return redirect()
->route('tweet.update.index', ['id' => $tweet->id])
->with('feedback.success', 'つぶやきを編集しました。');
}
}2. route/web.phpに追加
Route::put('/tweet/update/{id}', \App\Http\Controllers\Tweet\Update\PutController::class)->name('tweet.update.put')->where('id', '[0-9]+');
3. sail artisan make:request Tweet/UpdateRequest
<?php
namespace App\Http\Requests\Tweet;
use Illuminate\Foundation\Http\FormRequest;
class UpdateRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*/
public function authorize(): bool
{
return true;

* Get the validation rules that apply to the request.
*
* @return array<string, \Illuminate\Contracts\Validation\Rule|array|string>
*/
public function rules(): array
{
return [
'tweet' => 'required|max:140'
];
}
public function tweet(): string
{
return $this->input('tweet');
}
public function id(): int
{
return (int)$this->route('id');
}
}
4. resources/views/tweet/update.blade.phpに以下を追加
@if (session('feedback.success'))
<p style="color: green">{{ session('feedback.success') }}</p>
@endif削除処理の作成
1. sail artisan make:controller Tweet/DeleteController --invokable
