laravel5.2でRouteModelBinding後、NotFoundHttpException in RouteCollection.php line 161:がでる

Question

###前提・実現したいこと
Lara帳：はじめてのLaravel5.1(32)を参考に勉強しています。
PHP自体初心者の者です。
こちらのサイトはlaravel5.1ですが私はlaravel5.2を使用しています。

RouteModelBindingを行った後、記事の閲覧・編集・更新・削除ができなくなりました。
idが取得できていない？のでしょうか。

似たような質問がこちらの掲示板にあったので見たのですが、そちらはlaravel5.1を使用している方だったため、暗黙のモデルバインディング自体がなくできなくなっているようでした。

調べたところ、下記のようなものをよく見たのですが、この形を使用しなくてはいけないのでしょうか。ご教授お願いします。

Route::get('/user/{user}', function (App\User $user) {
    //
});

###発生している問題・エラーメッセージ

NotFoundHttpException in RouteCollection.php line 161:

解決しました。なんとも単純なことでした。
routes.php

Route::get('articles', ['as' => 'articles.index',
                        'uses' => 'ArticlesController@index']);
Route::get('articles/create', ['as' => 'articles.create',
                               'uses' => 'ArticlesController@create']);
Route::get('articles/{id}', ['as' => 'articles.show',
                             'uses' => 'ArticlesController@show']);
Route::post('articles', ['as' => 'articles.store',
                         'uses' => 'ArticlesController@store']);
Route::get('articles/{id}/edit', ['as' => 'articles.edit',
                                  'uses' => 'ArticlesController@edit']);
Route::patch('articles/{id}', ['as' => 'articles.update',
                               'uses' => 'ArticlesController@update']);
Route::delete('articles/{id}', ['as' => 'articles.destroy',
                                'uses' => 'ArticlesController@destroy']);

こちらの{id}を{article}に変更したら正常に動作しました。

目を通してくださった方々ありがとうございます。
