Phalcon MongoDB

Question

php7.0、Phalcon 3.2、MongoDB 3.2.14

我想连接到MongoDB，但在Phalcon文档中，我只想通过MongoClient()连接并使用它。我用的是php7.0，MongoClient()已经被弃用了。如何正确使用\MongoDB\Driver\Manager()和Phalcon？在services.php中，我写道：

/**
* MongoDB connection
*/
$di->set( "mongo", function () {
       $config = $this->getConfig();

        $db_string = sprintf( 'mongodb://%s:%s/%s', $config->mongodb->host, $config->mongodb->port, $config->mongodb->database );

        if( isset( $config->mongodb->user ) AND isset( $config->mongodb->password ) ) {
            $db_string = sprintf( 'mongodb://%s:%s@%s:%s/%s',
                $config->mongodb->user,
                (string)$config->mongodb->password,
                $config->mongodb->host,
                (string)$config->mongodb->port,
                $config->mongodb->database );
       }

        try {
            return new \MongoDB\Driver\Manager( $db_string );
        } catch (MongoConnectionException $e) {
            die( 'Failed to connect to MongoDB '.$e->getMessage() );
        }
    },
    true
);

它起作用了。但在模型中存在错误。在app/models/User.php中，我写道：

use Phalcon\Mvc\Collection;

class User extends Collection
{
    public function initialize()
    {
        $this->setSource('users');
    }
}

在控制器中：

class IndexController extends ControllerBase
{
    public function indexAction()
    {
        echo User::count();
    }
}

在浏览器中，我有以下内容：

Call to undefined method ::selectcollection()
#0 [internal function]: Phalcon\Mvc\Collection::_getGroupResultset(Array, Object(User), Object(MongoDB\Driver\Manager))
#1 /var/www/testing/app/controllers/IndexController.php(8): Phalcon\Mvc\Collection::count()
#2 [internal function]: IndexController->indexAction()
#3 [internal function]: Phalcon\Dispatcher->callActionMethod(Object(IndexController), 'indexAction', Array)
#4 [internal function]: Phalcon\Dispatcher->_dispatch()
#5 [internal function]: Phalcon\Dispatcher->dispatch()
#6 /var/www/testing/public/index.php(42): Phalcon\Mvc\Application->handle()
#7 {main}

我该怎么做才对？:)对不起，我来自俄罗斯:)
