Symfony的2.X服务引发异常

Question

我现在面临的问题与Symfony的2.x版的服务。当我尝试使用它的服务给我下面的错误

FatalErrorException: Error: Call to a member function has() on a non-object in C:\wamp\www\skerp8\vendor\symfony\symfony\src\Symfony\Bundle\FrameworkBundle\Controller\Controller.php line 202

at ??{main}() in C:\wamp\www\skerp8\web\app_dev.php line 0 

以下是我config.yml代码

services: 
    RouteCardControllerService: 
     class: Skerp\ProductionBundle\Controller\RouteCardController 
     arguments: 
      container: "@service_container" 

我打电话BlockInventoryController.php上述控制器用下面的代码。

$routecardControllerService = $this->get('RouteCardControllerService'); 
$routecardControllerService->updateRouteCardSummaryReportDetailsByRoutecardIdAction($routecardid) 

在RouteCardController.php文件

public function getRouteCardSummaryDetailsByRoutecardIdAction($routecardid){ 
    //Do something and return array of data 
} 

public function updateRouteCardSummaryReportDetailsByRoutecardIdAction($routecardid) { 
    $routecardSummaryDetails = $this->getRouteCardSummaryDetailsByRoutecardIdAction($routecardid); 
    //Do Something... 
} 

为什么会抛出一个错误。我应该如何实现一项服务，以便我可以访问其他控制器中的控制器的方法。

Answer 1

这是因为代码：

if (!$this->container->has('doctrine')) { 

在Symfony控制器。您没有在您的RouteCardController控制器上正确设置container服务。

你在哪里设置container服务，请复制粘贴您的控制器的一部分。你的控制器是否实现了ContainerAwareInterface？

注：这是真的不建议注射container，但服务，您真正需要的。
