Laravel更改連接動態

Question

如何改變laravel的連接形式控制器，但存儲在諸如數據庫管理數據庫的連接信息，我的例子：

我有我的數據庫中的數據庫的信息：

id, driver, database_name, username, password, host 

因此在我的控制器只是打電話：

$connection = Database::find(1); 
$users = new Users(); 
$users->setConnection([ 
    'driver' => $connection->driver, 
    'host' => $connection->host, 
    'username' => $connection->username, 
    'password' => $connection->password 
]); 
$users = $users->get();

我會去幫助這裏的。我們在app/Helpers/DatabaseConnection.php中創建一個。

namespace App\Helpers; 
use Config; 
use DB; 

class DatabaseConnection 
{ 
    public static function setConnection($params) 
    { 
     config(['database.connections.onthefly' => [ 
      'driver' => $params->driver, 
      'host' => $params->host, 
      'username' => $params->username, 
      'password' => $params->password 
     ]]); 

     return DB::connection('onthefly'); 
    } 
} 

現在某處控制器，我們嘗試

use App\Helpers\DatabaseConnection; 
... 

$params = Database::find(1); 
$connection = DatabaseConnection::setConnection($params); 
$users = $connection->select(...); 

注：未測試。我希望它的工作原理或只是引導你
