Question

我已经在yii中更新了ajax用于更新模型属性，但似乎模型没有保存在数据库中，并且我在检查模型时没有验证错误

视图

<?php echo CHtml::dropDownList('roomType', $bed->room_type, SiteBed::roomTypes(), array('class' => 'room-types',
                'ajax' => array(
                    'type' => 'POST',
                    'url' => Yii::app()->createUrl("admission/admit/bedUpdate", 'ajax' => TRUE)),
                    'data' => array('Bed[room_type]' => 'js:this.value', 'bed_id' => $bed->bed_id),
                    'update' => '#Bed_room_type'
                )
            )); ?>

控制器

public function actionBedUpdate()
{
    if(!isset($_POST['bed_id']))
        throw new CHttpException(400, 'Bad Request');

    if(!isset($_POST['Bed']))
        throw new CHttpException(400, 'Bad Request');

    $model = Bed::model()->findByPk($_POST['bed_id']);

    if($model===null)
        throw new CHttpException(404,'The requested page does not exist.');

    $model->attributes = $_POST['Bed'];

    $model->save();

    //    throw new CHttpException(422, 'Saving Error');
}

模型规则

/**
 * @return array validation rules for model attributes.
 */
public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('name, status, price, room_type, house_id', 'required'),
        array('status, room_type, house_id', 'numerical', 'integerOnly'=>true),
        array('name', 'length', 'max'=>150),
        array('description', 'length', 'max'=>500),
        array('price', 'length', 'max'=>10),
        array('date_created, date_modified', 'length', 'max'=>14),
        // The following rule is used by search().
        // @todo Please remove those attributes that should not be searched.
        array('bed_id, name, description, status, price, room_type, house_id, date_created, date_modified', 'safe', 'on'=>'search'),
    );
}

我认为您忘记为帖子请求添加csrf令牌

<?php echo CHtml::dropDownList('roomType', $bed->room_type, SiteBed::roomTypes(), array('class' => 'room-types',
                'ajax' => array(
                    'type' => 'POST',
                    'url' => Yii::app()->createUrl("admission/admit/bedUpdate", 'ajax' => TRUE)),
                    'data' => array(
                      'Bed[room_type]' => 'js:this.value', 
                      'bed_id' => $bed->bed_id, 
                      'YII_CSRF_TOKEN' => Yii::app()->request->csrfToken    
                    ),
                    'update' => '#Bed_room_type'
                )
            )); ?>

我发现yii生成的jQuery代码是问题所在，我忘了在这里提到我创建了多个CHtml :: dropDownList（＆＃39; roomType＆＃39;）因为我在这里使用了GridView，问题是如果dropDownList多次生成，yii将使用下拉元素的id，在这种情况下是roomtype。我认为yii会使用元素类（房间类型）。感谢您的回复

模型不保存在yii中
