Yii ajax 表单提交和更新？

Question

我正在尝试在我的网络项目中实现评论系统，我对 Yii 非常陌生。我希望用户能够提交评论，从而更新数据库，并重新呈现所有帖子的 cmets（注意：我不希望整个页面刷新）。

我正在尝试使用CHtml::ajaxSubmitButton 来实现这一点，但我似乎无法让它打电话。我不知道如何检查是否正在拨打电话。

我目前的代码如下：

_questionComment - 这部分呈现在“浏览”视图中

<div class="form">

<?php

    $form = $this -> beginWidget('CActiveForm', array(
        'id' => 'question-answer-form',
        'enableClientValidation'=>true,
        'clientOptions'=>array(
            'validateOnSubmit'=>true,
        ),
    ));

    $response = new QuestionAnswerForm;
?>

    <div class="row">
        <?php 
            echo $form->labelEx($response, 'link');
            echo $form->textField($response, 'link');
            echo $form->error($response, 'link');
        ?>
    </div>

    <div class="row">
        <?php 
            echo $form->labelEx($response, 'description');
            echo $form->textField($response, 'description');
            echo $form->error($response, 'description');
        ?>
    </div>

    <div class="row buttons">
         <?php echo CHtml::ajaxSubmitButton('Reply', 'comment', array(
             'update'=>'#comments',
             'type'=>'POST',
        )); ?>
    </div>

<?php $this->endWidget(); ?>

</div>

QuestionController/actionComment() - 应该处理 ajax 请求

public function actionComment()
        {
            if(Yii::app()->request->isAjaxRequest)
            {
                //current user has posted a response
                if(isset($_POST['QuestionAnswerForm']))
                {
                    $response = new QuestionAnswerForm;
                    $response->attributes = $_POST['QuestionAnswerForm'];
                    //answer form has passed inspection
                    if($response->validate())
                    {
                        //save new answer to database
                        $newAnswer = new QuestionAnswer;
                        $newAnswer->link = $response->link;
                        $newAnswer->description = $response->description;
                        $newAnswer->question_id = Yii::app()->getRequest()->getQuery('id');
                        $newAnswer->user_id = Yii::app()->user->getId();

                        //adds a timestamp using a default timezone 'GMT'
                        $newAnswer->timestamp = Timestamp::getCurrentTimeStamp();

                        $newAnswer->save();
                    }     
                }
            }
        }

browse - 这是渲染 cmets 的位置。用户提交评论后，我希望浏览页面再次部分呈现所有 cmets。我尝试使用 ajaxSubmitButton 中的“更新”参数来实现这一点。

<?php
/* 
 * @var $this QuestionController
 * @var $question Question
 * @var $answers QuestionAnswer
 */

    echo "<h1>" . $question['name'] . "</h1>";
    echo "<h3>" . $question['description'] . "</h3>"
?>

<? $this->renderPartial('_renderComments', array('answers'=>$answers)); ?>
<? $this->renderPartial('_questionComment'); ?>
