Question

由crud返回null对象生成的默认ActionAdmin。我已粘贴了操作代码。

public function actionAdmin()
{
    $model=new Messages('search');
    $model->unsetAttributes();  // clear any default values
    if(isset($_GET['Messages']))
        $model->attributes=$_GET['Messages'];
    echo "<pre>";
    print_r($model);exit;
    $this->render('admin',array(
        'model'=>$model,
    ));
}

/ ** *这是表“消息”的模型类。 * *以下是表'消息'中的可用列： * @property整数$ id * @property integer $ offer_id * @property string $ message * @property string $ created * / class Messages扩展了CActiveRecord { public function defaultScope（）{ 返回数组（ 'order'=＆gt;'创建了DESC' ）; } / ** * @return字符串关联的数据库表名称 * / public function tableName（） { 返回'消息'; }

/**
 * @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('offer_id, user_id, message', 'required'),
        array('offer_id, user_id', 'numerical', 'integerOnly'=>true),
        array('message', 'length', 'max'=>2000),
        array('message','filter','filter'=>array($obj=new CHtmlPurifier(),'purify')),
        // The following rule is used by search().
        // @todo Please remove those attributes that should not be searched.
        array('id, offer_id, user_id, message, created', 'safe', 'on'=>'search'),
    );
}

/**
 * @return array relational rules.
 */
public function relations()
{
    return array(
        'offer' => array(self::BELONGS_TO, 'Offers', 'offer_id'),
        'sender' => array(self::BELONGS_TO, 'Users', 'user_id')
    );
}

/**
 * @return array customized attribute labels (name=>label)
 */
public function attributeLabels()
{
    return array(
        'id' => 'Message ID',
        'offer_id' => 'Offer ID',
        'user_id' => 'Sender',
        'message' => 'Message',
        'created' => 'Sent',
    );
}

/**
 * Retrieves a list of models based on the current search/filter conditions.
 *
 * Typical usecase:
 * - Initialize the model fields with values from filter form.
 * - Execute this method to get CActiveDataProvider instance which will filter
 * models according to data in model fields.
 * - Pass data provider to CGridView, CListView or any similar widget.
 *
 * @return CActiveDataProvider the data provider that can return the models
 * based on the search/filter conditions.
 */
public function search()
{
    // @todo Please modify the following code to remove attributes that should not be searched.

    $criteria=new CDbCriteria;

    $criteria->compare('id',$this->id);
    $criteria->compare('offer_id',$this->offer_id);
    $criteria->compare('user_id',$this->user_id);
    $criteria->compare('message',$this->message,true);
    $criteria->compare('created',$this->created,true);

    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
    ));
}

/**
 * Returns the static model of the specified AR class.
 * Please note that you should have this exact method in all your CActiveRecord descendants!
 * @param string $className active record class name.
 * @return Messages the static model class
 */
public static function model($className=__CLASS__)
{
    return parent::model($className);
}

protected function beforeSave() {
    if ($this->isNewRecord)
        $this->created = date('Y-m-d H:i:s');

    return parent::beforeSave();
}

}
