Slim 3 Eloquent 初始化错误 Argument 1 must be Illuminate\Database\Capsule\Manager

Question

披露：这是我的第一个 Slim 应用程序

我试过将 Eloquent 与 Slim 3 一起使用，但似乎无法正常工作。我已经用 composer 安装了所有东西，遵循网站上的安装指南。

当我尝试使用我的用户模型（它扩展了 Eloquent 模型）时，我收到一个致命错误：

Fatal error: Call to a member function connection() on null in ****\vendor\illuminate\database\Eloquent\Model.php on line 3280

我的 appConfig 如下所示：

$config['db'] = [
    'driver'    => 'mysql',
    'host'      => '****',
    'database'  => '****',
    'username'  => '****',
    'password'  => '****',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
];

我根据文档将其传递给应用程序：

$app = new \Slim\App(["settings" => $config]);
$container = $app->getContainer();
$container['db'] = function (ContainerInterface $container) {
    $settings = $container->get('database');
    $capsule = new \Illuminate\Database\Capsule\Manager;
    $capsule->addConnection($settings);
    $capsule->setAsGlobal();
    $capsule->bootEloquent();

    return $capsule;
};

我的用户 class 看起来像这样：

class User extends Illuminate\Database\Eloquent\Model {}

我在 Whosebug 上找到了解决方法，如下所示：

use Illuminate\Database\Eloquent\Model as Eloquent;
use Illuminate\Database\Capsule\Manager;

    class User extends Eloquent {
            public function __construct(Manager $capsule, array $attributes = [])
        {
            parent::__construct($attributes);
        }
    }

但是如果我根据端口重写构造函数，我会得到一个不同的错误：

_Catchable fatal error: Argument 1 passed to Up\models\User::_construct() must be an instance of Illuminate\Database\Capsule\Manager, none given, called in ****\vendor\illuminate\database\Eloquent\Model.php on line 644 and defined in ****\models\User.php on line 14

我现在卡住了。请帮助

Answer 1

我找到了一个解决方案here，但似乎有点不合适。我只需要像这样单独初始化 Eloquent：

$capsule = new Capsule;
$capsule->addConnection($config['db']);
$capsule->setEventDispatcher(new Dispatcher(new Container));
$capsule->bootEloquent();

这样 $container['db'] = function () {} 部分就被排除了，但是现在一切正常了

编辑（供评论）：整个部分现在看起来像这样：

$app = new \Slim\App(["settings" => $config]);
$container = $app->getContainer();
/*$container['db'] = function (ContainerInterface $container) {
    $settings = $container->get('database');
    $capsule = new \Illuminate\Database\Capsule\Manager;
    $capsule->addConnection($settings);
    $capsule->setAsGlobal();
    $capsule->bootEloquent();

    return $capsule;
};*/

$capsule = new Capsule;
$capsule->addConnection($config['db']);
$capsule->setEventDispatcher(new Dispatcher(new Container));
$capsule->bootEloquent();
