无法使用getModule（）从模块文件中注册CssFile（）

Question

Instead of calling/registering the CSS in my view. i want to register it in my AbcModule.php since the CSS will be used thru out the module.

class Abc extends CWebModule
{

    protected $_assetsUrl;

    public function init()
    {
        $path = Yii::app()->module->getAssetsUrl();

        Yii::app()->clientScript->registerCssFile($path.'/css/abc.css', 'all');

       $this->setImport(array(
        'abc.models.*',
        'abc.components.*',
       ));

   }

   public function getAssetsUrl()
    {
        if ($this->_assetsUrl === null)
            $this->_assetsUrl = Yii::app()->getAssetManager()->publish(__DIR__ . '/assets', false, -1, true);
        return $this->_assetsUrl;
    }
}

in the code above i get this error

Missing argument 1 for CModule::getModule(), called in /Library/WebServer/Documents/dev/common/lib/yii/framework/base/CComponent.php on line 111 and defined

which is this line

$path = Yii::app()->module->getAssetsUrl();

i also tried

$path = Yii::app()->getModule("Abc")->getAssetsUrl();

but got this error

Fatal error: Call to a member function getAssetsUrl() on a non-object in /Library/WebServer/Documents/dev/frontend/modules/research/AbcModule.php on line 17

in my view i call it like this. and it works perfect

Yii::app()->clientScript->registerCssFile($this->module->getAssetsUrl().'/css/abc.css', 'all');

any idea what I'm doing wrong?

$path = $this->getAssetsUrl();
