Question

我正在尝试在我正在构建的自定义PHP框架中通过作曲家使用Laravel的Eloquent ORM，并且在我的控制器中调用create方法时出现了一个奇怪的错误。

错误：

致命错误：未捕获的异常＆＃39; Illuminate \ Contracts \ Container \ BindingResolutionException＆＃39;消息＆＃39;目标[Illuminate \ Contracts \ Debug \ ExceptionHandler]不可实例化。＆＃39; in /Users/justin/Sites/test/vendor/illuminate/container/Container.php:763 Stack trace：＃0 /Users/justin/Sites/test/vendor/illuminate/container/Container.php(644):Insuminate \ Container \ Container-＆gt; build（＆＃39; Illuminate \ Cont ...＆＃39;，Array）＃1 /Users/justin/Sites/test/vendor/illuminate/database/Connectors/ConnectionFactory.php(130）：Illuminate \ Container \ Container-＆gt; make（＆＃39; Illuminate \ Cont ...＆＃39;）＃2 [内部功能]：Illuminate \ Database \ Connectors \ ConnectionFactory-＆gt; Illuminate \ Database \ Connectors {closure }（）#Users/justin/Sites/test/vendor/illuminate/database/Connection.php(964）：call_user_func（Object（Closure））＃4 / Users / justin / Sites / test / vendor / illuminate / database /Connection.php(832):Illuminate \ Database \ Connection-＆gt; getPdo（）＃5 /Users/justin/Sites/test/vendor/illuminate/database/Connection.php(717):Illuminate \ Database \ Connection-＆gt ;在763行的/Users/justin/Sites/test/vendor/illuminate/container/Container.php中记录

数据库连接：

use Illuminate\Database\Capsule\Manager as Capsule;
$capsule = new Capsule();
$capsule->addConnection([
    'driver' => 'mysql',
    'host' => 'localhost',
    'username' => 'root',
    'password' => 'root',
    'database' => 'database',
    'port' => '3306',
    'charset' => 'utf-8',
    'collation' => 'utf8_unicode_ci'
]);
$capsule->bootEloquent();

型号：

use Illuminate\Database\Eloquent\Model as Eloquent;

class User extends Eloquent{

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

}

最后方法：

public function create($username = '', $email = ''){
    User::create([
        'username' => $username,
        'email' => $email
    ]);
}

有人能帮助我吗？

更新：已实现我使用的是错误版本的Illuminate，需要使用4.2

您的Eloquent初始化可能不完整。

以下是我在Silex应用程序中实现它的方法：

<?php
namespace App\Base\Provider\Database;

use Silex\Application;
use Illuminate\Events\Dispatcher;
use Illuminate\Container\Container;
use Illuminate\Database\Capsule\Manager as Capsule;

class DatabaseSummoner
{
    public static function setup(Application $app)
    {
        $app['db'] = $app->share(function () use ($app) {
            # Set up Fluent Query Builder
            $capsule     = new Capsule;
            $db_settings = $app['config']['db'];

            $capsule->addConnection(
                $db_settings['connections'][$db_settings['connection']]
            );

            return $capsule;
        });

        // Set the event dispatcher used by Eloquent models...
        $app['db']->setEventDispatcher(new Dispatcher(new Container));

        // These two have to be outside closure
        // Make the Capsule instance available globally via static methods...
        $app['db']->setAsGlobal();
        // Boot Eloquent ORM
        $app['db']->bootEloquent();
    }
}

然后在我的composer.json中，我需要"illuminate/database": "~5.3"和"illuminate/events": "~5.3"（这第二个是可选的，但如果你想使用模型事件，则很有用。）

最后，在__construct()课程的Application中，我致电DatabaseSummoner::setup($this);。

这明显不同于您的设置，但您可能会找到自己的方式。
