Yii: невозможно удалить вещи из панели администратора

Я yiibie, и у меня проблема, что любое событие, которое я пытаюсь удалить, не удаляется, и это дает мне ошибку, которая

Error 500: <h1>CDbException</h1> <p>CDbCommand failed to execute the SQL statement: SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`response_system`.`user_join_event`, CONSTRAINT `fk_user_join_event_event1` FOREIGN KEY (`event_id`) REFERENCES `event` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION). The SQL statement executed was: DELETE FROM `event` WHERE `event`.`id`=18 (C:\wamp\apps\yii\db\CDbCommand.php:357)</p><pre>#0 C:\wamp\apps\yii\db\ar\CActiveRecord.php(1745): CDbCommand->execute(). 

Я могу легко обновить событие, как я могу обновить изображение, но я не могу его удалить. Это мой EventController

 class EventController extends RController { /** * @var string the default layout for the views. Defaults to '//layouts/column2', meaning * using two-column layout. See 'protected/views/layouts/column2.php'. */ public $layout='//layouts/admin'; /** * @return array action filters */ public function filters() { return array( // 'accessControl', // perform access control for CRUD operations // 'postOnly + delete', // we only allow deletion via POST request 'rights', ); } /** * Specifies the access control rules. * This method is used by the 'accessControl' filter. * @return array access control rules */ public function accessRules() { return array( array('allow', // allow all users to perform 'index' and 'view' actions 'actions'=>array('index','view'), 'users'=>array('*'), ), array('allow', // allow authenticated user to perform 'create' and 'update' actions 'actions'=>array('create','update'), 'users'=>array('@'), ), array('allow', // allow admin user to perform 'admin' and 'delete' actions 'actions'=>array('admin','delete'), 'users'=>array('admin'), ), array('deny', // deny all users 'users'=>array('*'), ), ); } /** * Displays a particular model. * @param integer $id the ID of the model to be displayed */ public function actionView($id) { $this->render('view',array( 'model'=>$this->loadModel($id), )); } public function actionAllevent() { $allmodels=Event::model()->findAll(array('order'=>'id DESC')); $this->layout='main'; $this->render('allevent' ,array('allmodels'=>$allmodels)); } /** * Creates a new model. * If creation is successful, the browser will be redirected to the 'view' page. */ public function actionCreate() { $model=new Event; // Uncomment the following line if AJAX validation is needed // $this->performAjaxValidation($model); if(isset($_POST['Event'])) { $rnd = rand(0,9999); // generate random number between 0-9999 $model->attributes=$_POST['Event']; $uploadedFile=CUploadedFile::getInstance($model,'image'); $fileName = "{$rnd}-{$uploadedFile}"; // random number + file name $model->image = $fileName; if($model->save()) { $uploadedFile->saveAs(Yii::app()->basePath.'/../img/'.$fileName); // image will uplode to rootDirectory/event/ $this->redirect(array('admin')); } $this->redirect(array('view','id'=>$model->id)); } $this->render('create',array( 'model'=>$model, )); } /** * Updates a particular model. * If update is successful, the browser will be redirected to the 'view' page. * @param integer $id the ID of the model to be updated */ public function actionUpdate($id) { $model=$this->loadModel($id); // Uncomment the following line if AJAX validation is needed // $this->performAjaxValidation($model); if(isset($_POST['Event'])) { $_POST['Event']['image'] = $model->image; $model->attributes=$_POST['Event']; $uploadedFile=CUploadedFile::getInstance($model,'image'); if($model->save()) { if(!empty($uploadedFile)) // check if uploaded file is set or not { $uploadedFile->saveAs(Yii::app()->basePath.'/../img/'.$model->image); } $this->redirect(array('admin')); } $this->redirect(array('view','id'=>$model->id)); } $this->render('update',array( 'model'=>$model, )); } /** * Deletes a particular model. * If deletion is successful, the browser will be redirected to the 'admin' page. * @param integer $id the ID of the model to be deleted */ public function actionDelete($id) { if(Yii::app()->request->isPostRequest) { // we only allow deletion via POST request $this->loadModel($id)->delete(); // if AJAX request (triggered by deletion via admin grid view), we should not redirect the browser if(!isset($_GET['ajax'])) $this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('admin')); } else throw new CHttpException(400,'Invalid request. Please do not repeat this request again.'); } /** * Lists all models. */ public function actionIndex() { $dataProvider=new CActiveDataProvider('Event'); $this->render('index',array( 'dataProvider'=>$dataProvider, )); } /** * Manages all models. */ public function actionAdmin() { $model=new Event('search'); $model->unsetAttributes(); // clear any default values if(isset($_GET['Event'])) $model->attributes=$_GET['Event']; $this->render('admin',array( 'model'=>$model, )); } /** * Returns the data model based on the primary key given in the GET variable. * If the data model is not found, an HTTP exception will be raised. * @param integer $id the ID of the model to be loaded * @return Event the loaded model * @throws CHttpException */ public function loadModel($id) { $model=Event::model()->findByPk($id); if($model===null) throw new CHttpException(404,'The requested page does not exist.'); return $model; } /** * Performs the AJAX validation. * @param Event $model the model to be validated */ protected function performAjaxValidation($model) { if(isset($_POST['ajax']) && $_POST['ajax']==='event-form') { echo CActiveForm::validate($model); Yii::app()->end(); } } } 

И это моя Event model

 <?php /** * This is the model class for table "event". * * The followings are the available columns in table 'event': * @property integer $id * @property string $image * * The followings are the available model relations: * @property UserJoinEvent[] $userJoinEvents */ class Event extends CActiveRecord { /** * Returns the static model of the specified AR class. * @param string $className active record class name. * @return Event the static model class */ public static function model($className=__CLASS__) { return parent::model($className); } /** * @return string the associated database table name */ public function tableName() { return 'event'; } /** * @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('image', 'required'), array('image', 'length', 'max'=>45), // The following rule is used by search(). // Please remove those attributes that should not be searched. array('id, image', 'safe', 'on'=>'search'), // this will allow empty field when page is update (remember here i create scenario update) array('image', 'file','types'=>'jpg, gif, png, mp4', 'allowEmpty'=>true, 'safe'=>false, 'on'=>'insert,update'), array('image', 'length', 'max'=>255, 'on'=>'insert,update'), ); } /** * @return array relational rules. */ public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'userJoinEvents' => array(self::HAS_MANY, 'UserJoinEvent', 'event_event_id'), ); } /** * @return array customized attribute labels (name=>label) */ public function attributeLabels() { return array( 'id' => 'ID', 'image' => 'Image', ); } /** * Retrieves a list of models based on the current search/filter conditions. * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions. */ public function search() { // Warning: Please modify the following code to remove attributes that // should not be searched. $criteria=new CDbCriteria; $criteria->compare('id',$this->id); $criteria->compare('image',$this->image,true); return new CActiveDataProvider($this, array( 'criteria'=>$criteria, )); } } 

И это мой view file(_form.php)

 <?php /* @var $this EventController */ /* @var $model Event */ /* @var $form BSActiveForm */ ?> <?php $form=$this->beginWidget('bootstrap.widgets.BsActiveForm', array( 'id'=>'event-form', // Please note: When you enable ajax validation, make sure the corresponding // controller action is handling ajax validation correctly. // There is a call to performAjaxValidation() commented in generated controller code. // See class documentation of CActiveForm for details on this. 'enableAjaxValidation'=>false, //form options array... 'htmlOptions' => array( 'enctype' => 'multipart/form-data', ), )); ?> <p class="help-block">Fields with <span class="required">*</span> are required.</p> <?php echo $form->errorSummary($model); ?> <?php //echo $form->textFieldControlGroup($model,'image',array('maxlength'=>45)); ?> <!--this is for data path entry--> <div class="row"> <?php echo $form->labelEx($model,'image'); ?> <?php echo CHtml::activeFileField($model, 'image'); ?> <!--by this we can upload image--> <?php echo $form->error($model,'image'); ?> </div> <?php if($model->isNewRecord!='1') ?> <div class="row"> <?php echo CHtml::image(Yii::app()->request->baseUrl.'/img/'.$model->image,"",array("width"=>200)); ?> <!--Image shown here if page is update page--> </div> <br> <?php echo BsHtml::submitButton('Submit', array('color' => BsHtml::BUTTON_COLOR_PRIMARY)); ?> <?php $this->endWidget(); ?> 

Это структура таблицы userjoinevent Table для таблицы user_join_event

 -- CREATE TABLE IF NOT EXISTS `user_join_event` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) NOT NULL, `event_id` int(11) NOT NULL, `date_created` varchar(45) DEFAULT NULL, `date_modified` varchar(45) DEFAULT NULL, PRIMARY KEY (`id`), KEY `fk_user_join_event_user1_idx` (`user_id`), KEY `fk_user_join_event_event1_idx` (`event_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=91 ; 

И это ограничение для таблицы

 ALTER TABLE `user_join_event` ADD CONSTRAINT `fk_user_join_event_event1` FOREIGN KEY (`event_id`) REFERENCES `event` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION, ADD CONSTRAINT `fk_user_join_event_user1` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION; 

И это модель UserJoinEvent

 <?php /** * This is the model class for table "user_join_event". * * The followings are the available columns in table 'user_join_event': * @property integer $id * @property integer $user_id * @property integer $event_id * @property string $date_created * @property string $date_modified * * The followings are the available model relations: * @property Event $event * @property User $user */ class UserJoinEvent extends CActiveRecord { /** * Returns the static model of the specified AR class. * @param string $className active record class name. * @return UserJoinEvent the static model class */ public static function model($className=__CLASS__) { return parent::model($className); } /** * @return string the associated database table name */ public function tableName() { return 'user_join_event'; } /** * @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('user_id, event_id', 'required'), array('user_id, event_id', 'numerical', 'integerOnly'=>true), array('date_created, date_modified', 'length', 'max'=>45), // The following rule is used by search(). // Please remove those attributes that should not be searched. array('id, user_id, event_id, date_created, date_modified', 'safe', 'on'=>'search'), array('date_modified','default', 'value'=>new CDbExpression('NOW()'),//automatically add the current date in mysql feild 'setOnEmpty'=>false,'on'=>'update'), array('date_created,date_modified','default', 'value'=>new CDbExpression('NOW()'),'setOnEmpty'=>false,'on'=>'insert'), ); } /** * @return array relational rules. */ public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'event' => array(self::BELONGS_TO, 'Event', 'event_id'), 'user' => array(self::BELONGS_TO, 'User', 'user_id'), ); } /** * @return array customized attribute labels (name=>label) */ public function attributeLabels() { return array( 'id' => 'ID', 'user_id' => 'User', 'event_id' => 'Event', 'date_created' => 'Date Created', 'date_modified' => 'Date Modified', ); } /** * Retrieves a list of models based on the current search/filter conditions. * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions. */ public function search() { // Warning: Please modify the following code to remove attributes that // should not be searched. $criteria=new CDbCriteria; $criteria->compare('id',$this->id); $criteria->compare('user_id',$this->user_id); $criteria->compare('event_id',$this->event_id); $criteria->compare('date_created',$this->date_created,true); $criteria->compare('date_modified',$this->date_modified,true); return new CActiveDataProvider($this, array( 'criteria'=>$criteria, )); } } 

Пожалуйста, помогите мне с этим, спасибо.
