PHP Laravel Lumenでデータベースへの接続を確立するには？

Question

私はルーメンベースのクエリをlocalhostで実行しようとしています。適切なデータベース名を正しく呼び出す方法がわかりません。

EDIT：私は以下のエラーを取得しています理由は、私のプロジェクトで私の.envファイル内のDB名の名前です。私の.envファイルのDB_DATABASE=mydbschemaname行にデータベース名が必要ですが、それをどのように見つけることができますか？私はどこでもそれを見つけることができません。

次のように私が持っているコードは、APP->のHttpに位置routes.phpある：APP-> HTTP->コントローラで

$app->get('/records', 'UserController@index'); 

UserController.php：

namespace App\Http\Controllers; 

use App\User; 
use App\Http\Controllers\Controller; 
use Illuminate\Http\Request; 

class UserController extends Controller 
{ 

    public function index() { 
     $users = User::all(); 
     return response()->json($users); 
    } 
} 

User.phpアプリ - > Http：

namespace App; 

use Illuminate\Auth\Authenticatable; 
use Laravel\Lumen\Auth\Authorizable; 
use Illuminate\Database\Eloquent\Model; 
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract; 
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract; 

class User extends Model implements 
    AuthenticatableContract, 
    AuthorizableContract 
{ 
    use Authenticatable, Authorizable; 

    protected $fillable = [ 
     'name', 'email', 
    ]; 

    protected $hidden = [ 
     'password', 
    ]; 
} 

APP->データベース - >移行中

[date]_create_users_table.php：

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

class CreateUsersTable extends Migration 
{ 
    public function up() 
    { 
     Schema::create('users', function (Blueprint $table) { 
      $table->increments('id'); 
      $table->string('name', 200); 
      $table->string('email', 200)->unique(); 
      $table->string('password', 200); 
      $table->timestamps(); 
     }); 

     DB::table('users')->insert(
      ['id' => 1, 'name' => 'example', 'email' => 'example@example.com', 'password' => 'thisisthepassword', 'updated_at' => '2015-10-15 01:23:45', 'created_at' => '2015-10-15 01:23:45'] 
     ); 
    } 

    public function down() 
    { 
     Schema::drop('users'); 
    } 
} 

その後、もちろん、私が持っているに位置database.php APP->ベンダー> laravel->ルーメン-framework->設定：

最後に、ここではappフォルダの外に位置私.envファイルは、ルートプロジェクトフォルダに、です：

APP_ENV=local 
APP_DEBUG=true 
APP_KEY=SomeRandomKey!!! 

APP_LOCALE=en 
APP_FALLBACK_LOCALE=en 

DB_CONNECTION=mysql 
DB_HOST=localhost 
DB_PORT=3306 
DB_DATABASE=database 
DB_USERNAME=homestead 
DB_PASSWORD=secret 

CACHE_DRIVER=memcached 
SESSION_DRIVER=memcached 
QUEUE_DRIVER=database 

私はDB_DATABASEの名前を変更する必要があるのが最後のファイル（.env）だと思っていますが、私は完全にはわかりません。どんな助けもありがとう。

FYI：ここでの最終結果は、データベースに接続して、ユーザーテーブルに追加するユーザーのレコードを表示できるようにすることです。

Answer 1

スキーマ名が「データベース」のデータベースはありますか？

データベースが設定されているので、以下のようにDB_プロパティを変更する必要があります。

など。

DB_CONNECTION=mysql 
DB_HOST=localhost 
DB_PORT=3306 
DB_DATABASE=mydbschemaname 
DB_USERNAME=dbadmin 
DB_PASSWORD=myverysecretpassword
