RESTfulなcontrollerを作成

$ php artisan make:controller ArticleController

以下ができる

vi app/Http/Controllers/ArticleController.php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
class ArticleController extends Controller
{
    //
}

vi app/Http/routes.php

Route::resource('article', 'ArticleController');

vi app/Http/Controllers/ArticleController.php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Article;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class ArticleController extends Controller
{
   public function index()
   {
       return 'index';
   }
   public function create()
   {
       return 'create';
   }
   public function store()
   {
       return 'store';
   }
   public function show($id)
   {
       return 'show' . $id;
   }
   public function edit($id)
   {
       return 'edit' . $id;
   }
   public function update($id)
   {
       return 'update' . $id;
   }
   public function destroy($id)
   {
       return 'destroy' . $id;
   }
}

ttp://localhost/article/1でshow1が表示

その他は以下の通り

$ php artisan route:list
+--------+-----------+------------------------+-----------------+------------------------------------------------+------------+

|        | GET|HEAD  | article/{article}      | article.show    | App\Http\Controllers\ArticleController@show     |            |
|        | GET|HEAD  | article/{article}/edit | article.edit    | App\Http\Controllers\ArticleController@edit    |            |
  • indexがリスト表示
  • createが新規入力フォーム画面表示
  • storeが新規追加処理
  • showが個別詳細表示
  • editが個別入力フォーム更新画面表示
  • updateが個別更新処理
  • destoryが個別削除処理

テンプレートdirも作る

mkdir resources/views/article

restful controller

-ArticleController.php

class ArticleController extends Controller
{
  public function index()
  {
       $articles = \App\Article::get();
       $data = ['articles' => $articles];
       return view('articles.index', $data);
  }
  public function create()
  {
      return view('articles.create');
  }
  public function store(Request $request)
  {
      $article = \App\Article::create();
      $article->title= $request->title;
      $article->body= $request->body;
      $article->save();
      return redirect()->to('/article');
  }
  public function show($id)
  {
      $article = \App\Article::find($id);
      $data = ['article' => $article];
      return view('articles.show', $data);
  }
  public function edit($id)
  {
      $article = \App\Article::find($id);
      $data = ['article' => $article];
      return view('articles.edit', $data);
  }
  public function update(Request $request, $id)
  {
      $article = \App\Article::find($id);
      $article->title= $request->title;
      $article->body= $request->body;
      $article->save();
      return redirect()->to('/article');
  }
  public function destroy($id)
  {
      $article = \App\Article::find($id);
      $article->delete();
      return redirect()->to('/article');
  }
}
