Laravel Adminでmigrate してデータが消えたら

Laravel Adminを使っていて、`migrate fresh`したら、初期の管理者データが消えてしまいました。
さくっと直せるようにLaravel Adminで使われているSeederを利用して、データを投入できるようにします

#Seeder 作成

```
php artisan make:seeder AdminTablesSeeder 
```
`vendor/encore/laravel-admin/src/Auth/Database/AdminTablesSeeder.php`にLaravelAdminのSeederがあるので中身をコピーし、
ディレクトリ構成が異なるので、インポートを多少書き足します。
そうすると下記のように書き換えられます。

```php:AdminTablesSeeder
<?php

use Illuminate\Database\Seeder;
use Encore\Admin\Auth\Database\Administrator;
use Encore\Admin\Auth\Database\Role;
use Encore\Admin\Auth\Database\Permission;
use Encore\Admin\Auth\Database\Menu;

class AdminTablesSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // create a user.
        Administrator::truncate();
        Administrator::create([
            'username' => 'admin',
            'password' => bcrypt('admin'),
            'name'     => 'Administrator',
        ]);

        // create a role.
        Role::truncate();
        Role::create([
            'name' => 'Administrator',
            'slug' => 'administrator',
        ]);

        // add role to user.
        Administrator::first()->roles()->save(Role::first());

        //create a permission
        Permission::truncate();
        Permission::insert([
            [
                'name'        => 'All permission',

            ],
        ]);

        Role::first()->permissions()->save(Permission::first());

        // add default menus.
        Menu::truncate();
        Menu::insert([
            [
                'parent_id' => 0,
                'order'     => 1,

                'icon'      => 'fa-tasks',
                'uri'       => '',

                'uri'       => 'auth/roles',
            ],
            [

            [

                'uri'       => 'auth/logs',
            ],
        ]);

        // add role to menu.
        Menu::find(2)->roles()->save(Role::first());
    }
}


```

seederの呼び出しに追加します

```php:DatabaseSeeder 

<?php

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call([
            AdminTablesSeeder::class,
        ]);
    }
}
```

#Composerのオートローダー再生成

```
composer dump-autoload
```

#実行
```
php artisan db:seed
#または
php artisan db:seed --class=AdminTablesSeeder 
```
