我正在尝试创建一个注释系统。当我的表单发布时，并调用我的"actionCreate"函数。我在firebug上出错了。但是数据存储在我的数据库中。知道我做错了什么吗？
这是我在控制器中的操作
public function actionCreate()
{
/** @var Comment $comment */
$comment = Yii::createComponent($this->module->commentModelClass);
// Uncomment the following line if AJAX validation is needed
$user=new User;
$this->performAjaxValidation(array($comment, $user));
//end of Ajax validation
$_user = Yii::app()->request->getPost('User');
if(isset($_POST[$cClass=get_class($comment)], $_user))
{
$comment->attributes = $_POST[$cClass];
//$comment->type = $_POST[$cClass]['type'];
//$comment->key = $_POST[$cClass]['key'];
$user->attributes = $_user;
// determine current users id
if (Yii::app()->user->isGuest) {
$comment->userId = null;
} else {
$comment->userId = Yii::app()->user->id;
}
if(Yii::app()->request->isAjaxRequest)
{
/* the error happens here */
if($comment->save())
{
// refresh model to replace CDbExpression for timestamp attribute
$comment->refresh();
// create new comment model for empty form
$comment = Yii::createComponent($this->module->commentModelClass);
//$comment->type = $_POST[$cClass]['type'];
//$comment->key = $_POST[$cClass]['key'];
}
else {
//Return messages from try/catch
echo CJSON::encode(array(
'msg' => 'Check your form, and fill up all required fields'
));
}
Yii::app()->end();
}
else
{
if($comment->save()) {
$this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('view','id'=>$comment->id));
}
else {
//Return messages from try/catch
echo CJSON::encode(array(
'msg' => 'Check your form, and fill up all required fields'
));
}
Yii::app()->end();
}
}
}

错误我得到
<b>Fatal error</b>: Class name must be a valid object or a string in <b>/Library/WebServer/Documents/dev/common/lib/yii/framework/db/ar/CActiveRecord.php</b> on line <b>395</b><br />
这是CActiveRecord.php
public static function model($className=__CLASS__)
{
if(isset(self::$_models[$className]))
return self::$_models[$className];
else
{
$model=self::$_models[$className]=new $className(null); //this is line 395
$model->attachBehaviors($model->behaviors());
return $model;
}
}
在我的例子中，这就是注释的工作方式：
public function actionCreate(){
$comment = new Comment;
if($_POST[get_class($comment)]){
// save data here
if ( $comment->save() ) {
// comment saved !!
} else {
// comment not saved
}
}
$this->render('new',array('comment'=>$comment));
}
在您的案例中，注释是一个组件，而不是一个模型
我不知道是否要检查是否提交了表格。
注释模型示例：
class Comment extends CActiveRecord
{
$id;
public static function model($className=__CLASS__)
{
return parent::model($className);
}
public function rules(){
}
}
