Laravel 6で旅行予約サイトを作成してAuth0で認証機能を追加する

# はじめに
この記事はLaravelフレームワークで旅行予約サイトを作成して、Auth0で認証機能を追加する手順で、[こちらの原文](https://auth0.com/blog/build-a-laravel-6-app-with-authentication/)を元に作成しています。完成版のソースコードは[ここ](https://github.com/hollylawly/travel-planet-crud)で公開しています。


# 前提条件と検証環境
sshキーペアの作成、PHP, Virtualbox, Vagrant, Node, NPMのインストール、およびAuth0の無料アカウントの取得とテナントの作成が完了していることが前提となっています。Auth0の無料アカウント取得がまだの方は[こちら](https://qiita.com/furuth/items/8826b66a3ec2b2b14222)の記事を参照の上ご準備をお願いします。

- **OS** : `macOS Mojave 10.14.6`
- **PHP** : `7.2.24`
- **Virtualbox** : `6.0.14 r133895 (Qt5.6.3)`
- **Vagrant** : `2.2.6`
- **node** : `10.15.3`
- **npm** : `6.12.0`

# 手順
## 各種ツールのインストール
PHP7.2をインストールします。この記事では[こちら](https://qiita.com/naente_dev/items/b7c4b89616473dcec2fd)を参考にインストールしています。
composer(PHPのパッケージ管理ツール)をインストールします。この記事では[こちら](https://qiita.com/tomk79/items/e6e1db94ea8b661b1e86)を参考にインストールしています。インストール後、~/.composer/vendor/binをPATHにセットします。**その他のツールのインストール手順は割愛します。Qiitaに多数記事が掲載されているのでそれらをご参照お願いします。**
<br>
composerを使ってLaravelをインストールします。

```console
$ composer global require laravel/installer
```

## Laravel Homesteadの設定
Laravelのプロジェクトを作成します。

```console
$ laravel new travel-planet-crud
$ cd travel-planet-crud
```

Laravel Homestead Vagrant boxをダウンロードします。

```console
$ vagrant box add laravel/homestead
```

Homesteadをインストールします。

```console
$ pwd
~/travel-planet-crud
$ composer require laravel/homestead --dev
```

Homestead.yaml(構成情報ファイル)を作成します。

```console
$ php vendor/bin/homestead make
```

/etc/hostsファイルにホスト名を追加します。**IPはHomestead.yamlに記載されています。**

```vim:/etc/hosts
192.168.10.10   homestead.test
```

仮想マシンを起動します。

```console
$ pwd
~/travel-planet-crud
$ vagrant up
```

Chrhomeで`http://homestead.test`にアクセスしてページが表示されることを確認します。

## Routeの作成
routes/web.phpを編集してルートを指定します。**手順の後半でApplicationとAuth0を連携します。ここでは連携後のAuth0モデルを利用することを前提としています。**

```php
<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::view('/', 'home'); 
Route::get('/hotels', 'HotelController@index'); 
Route::get('/auth0/callback', '\Auth0\Login\Auth0Controller@callback' )->name('auth0-callback');
Route::get('/login', 'Auth\Auth0IndexController@login')->name('login');
Route::get('/logout', 'Auth\Auth0IndexController@logout')->name('logout')->middleware('auth');

Route::group(['prefix' => 'dashboard', 'middleware' => 'auth'], function() {
    Route::view('/', 'dashboard/dashboard');
    Route::get('reservations/create/{id}', 'ReservationController@create');
    Route::resource('reservations', 'ReservationController')->except('create');
});
```

## Databaseの作成
reservation, hotels, roomsの3つのテーブルを作成します。

### 設定
MySQLのパラメータを修正します。

```vim:travel-planet-crud/.env
---省略---
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret
--省略--
```

### Modelの作成
Modelファイルを作成します。**この記事ではLaravel's Eloquent ORMを利用したModelを作成します。**

```console
$ pwd
~/travel-planet-crud
$ mkdir app/Models
$ php artisan make:model Models/Hotel -m 
$ php artisan make:model Models/Room -m
$ php artisan make:model Models/Reservation -m
```

Hotel.php, Room.php, Reservation.phpを編集して属性とテーブル間の相関を定義します。

```php:app/Models/Hotel.php
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Hotel extends Model
{
    public $timestamps = false;
    protected $fillable = [
        'name',
        'location',
        'description',
        'image'
    ];

    public function rooms() {
        return $this->hasMany('App\Models\Room');
    }
}
```

```php:app/Models/Room.php
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Room extends Model
{
    public $timestamps = false;
    protected $fillable = [
        'hotel_id',
        'type',
        'description',
        'price',
        'image'
    ];

    public function hotel() {
        return $this->belongsTo('App\Models\Hotel');
    }
}
```

```php:app/Models/Reservation.php
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Reservation extends Model
{
    protected $fillable = [
        'user_id',
        'room_id',
        'num_of_guests',
        'arrival',
        'departure'
    ];

    public function room() {
        return $this->belongsTo('App\Models\Room');
    }
}
```

### Migrationの作成
LaravelのMigration(データベースのバージョンコントロール)を作成します。
プロジェクトルートディレクトリ配下のdatabase/migrations/xxxx_xx_xx_xxxxx_create_hotels_table.phpを編集します。

```php:travel-planet-crud/database/migrations/xxxx_xx_xx_xxxxx_create_hotels_table.php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateHotelsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('hotels', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('location');
            $table->string('description');
            $table->string('image');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('hotels');
    }
}
```

database/migrations/xxxx_xx_xx_xxxxx_create_rooms_table.phpを編集します。

```php:travel-planet-crud/database/migrations/xxxx_xx_xx_xxxxx_create_rooms_table.php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateRoomsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('rooms', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->unsignedBigInteger('hotel_id');
            $table->foreign('hotel_id')->references('id')->on('hotels');
            $table->string('type');
            $table->string('description');
            $table->decimal('price', 10, 2);
            $table->string('image');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('rooms');
    }
}
```

database/migrations/xxxx_xx_xx_xxxxx_create_reservations_table.phpを編集します。

```php:travel-planet-crud/database/migrations/xxxx_xx_xx_xxxxx_create_reservations_table.php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateReservationsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('reservations', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->timestamps();
            $table->string('user_id');
            $table->unsignedBigInteger('room_id');
            $table->foreign('room_id')->references('id')->on('rooms');
            $table->integer('num_of_guests');
            $table->date('arrival');
            $table->date('departure');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('reservations');
    }
}
```

### データの投入
Seeder Fileを作成します。

```console
$ pwd
~/travel-planet-crud
$ php artisan make:seeder HotelSeeder
$ php artisan make:seeder RoomSeeder
$ php artisan make:seeder ReservationSeeder
```

database/HotelSeeder.phpを編集します。

```php:travel-planet-crud/database/HotelSeeder.php
<?php

use Illuminate\Database\Seeder;
use App\Models\Hotel;

class HotelSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // array of specific hotels to populate database
        $hotels = [

            ]
        ];

        foreach ($hotels as $hotel) {
            Hotel::create(array(

## Controllerの作成
HotelControllerとReservationControllerを作成します。

```console
$ pwd
~/travel-planet-crud
$ php artisan make:controller HotelController
$ php artisan make:controller ReservationController --resource
```

app/Http/Controllers/ReservationController.phpを編集します。

```php:travel-planet-crud/app/Http/Controllers/ReservationController.php

# おわりに
Laravelのような便利なフレームワークのおかげで、今はスタイリッシュなWeb Applicationを誰でも簡単に実装できるようになりました。であれば、Web Applicationに必須の認証機能も簡単に実装できるべきかと思います。ソフトウェア開発者の皆様には、ボタン設定で簡単に認証機能を実装できるAuth0を利用して、ワクワクするようなWeb Applicationを早く世に送り出して頂きたいですね。
