php - 使用 Yii 框架的 "extends CAction"类

Question

在本Yii框架教程中 http://www.yiiframework.com/doc/guide/1.1/en/basics.controller#action

我想把我的 Action 从一个 Controller 放到一个单独的 Action 文件中并按照说明“创建一个 Action 类”

这是我的 Action 类文件

class LoginAction extends CAction
{

    private $contents = array();
    public function run(){
        $loginmodel = new LoginForm;

        //answer ajax validating request
        if(isset($_POST['ajax']) && $_POST['ajax']==='login-form'){
            echo CActiveForm::validate($loginmodel);
            Yii::app()->end();
        }

        //collect user input data to do login
        if(isset($_POST["LoginForm"]))
        {
            $loginmodel->attributes = $_POST["LoginForm"];
            // validate user input and redirect to the previous page if valid
            if($loginmodel->validate() && $loginmodel->login()){ //<--invoking here the login and validate function
                $this->redirect(Yii::app()->user->returnUrl);
            }
        }

        $this->contents["loginmodel"] =  $loginmodel;
        $this->render('index',$this->contents); 
    }    

}

在我的 Controller 中

class SandboxController extends Controller{       
    public function actions(){
        // return external action classes, e.g.:
            return array(
            'authlog'=>'application.controllers.authentication.LoginAction',
            // page action renders "static" pages stored under 'protected/views/site/pages'
            // They can be accessed via: index.php?r=site/page&view=FileName
            'page'=>array(
                'class'=>'CViewAction',
            ),
        );   
    }
}

然后我使用浏览单独的 Action Controller

http://localhost/mysite/index.php/sandbox/authlog/login

我的错误是

LoginAction and its behaviors do not have a method or closure named "render".

我做错了什么吗？谢谢。

这是堆栈跟踪

CException LoginAction and its behaviors do not have a method or closure named "render".

问题出在这行代码上:

$this->render('index',$this->contents);

如果它在 Controller 中，这会很好，但是一旦代码被移动到专用操作类中，就不再有 render 方法可以在 $this 上调用>，因此出现错误。

您只需要先获取对 Controller 的引用，然后在其上调用render:

$controller=$this->getController();
$controller->render('index',$this->contents);
