在Yii应用程序中,我将数据显示为表格。我使用CGridView
来处理(基于搜索的)数据过滤和排序。它有效。
现在我在ENUM
数据库表中添加了status
列user
。在网格中,我可以对此进行排序和过滤,但只能通过表中的值进行排序和过滤。嗯,这很有道理。但是用户实际上并不知道它是如何在数据库中保存的,并且与标签一起工作(并希望对其进行排序和过滤)。
有没有办法通过Yii中ENUM
数据库表列的自定义标签提供排序和过滤(使用CActiveRecord
模型和CGridView
生成的数据网格)?
数据库表
CREATE TABLE `users` (
`userid` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`email` varchar(45) NOT NULL,
...
`status` enum('processed', 'waiting') NOT NULL,
PRIMARY KEY (`userid`),
UNIQUE KEY `email_UNIQUE` (`email`)
);
User
模型
/**
* ...
* @property string $userid
* @property string $email
* ...
* @property string $status
*/
class User extends CActiveRecord
{
public function tableName()
{
return 'users';
}
public function getFirstAndLastName(){
return CHtml::encode($this->firstname." ".$this->lastname);
}
public function rules()
{
return array(
...
array('userid, email, status', 'safe', 'on'=>'search'),
);
}
public function attributeLabels()
{
return array(
'userid' => 'Userid',
'email' => 'Email',
...
'status' => Yii::t('app', 'status'),
);
}
public function relations()
{
return array(
...
);
}
public function search()
{
$criteria=new CDbCriteria;
$criteria->compare('userid',$this->userid,true);
$criteria->compare('email',$this->email,true);
...
$criteria->compare('status',$this->status,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
"pagination"=>array(
"pageSize"=>25
)
));
}
public static function model($className=__CLASS__)
{
return parent::model($className);
}
protected function beforeSave()
{
return parent::beforeSave(); // TODO: Change the autogenerated stub
}
public function getProcessingStatus()
{
return Yii::t('app', $this->processing_status);
}
}
UserController
class UserController extends Controller
{
...
/**
* Manages all models.
*/
public function actionAdmin()
{
// Yii::app()->cache->flush();
$model=new User('search');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['User']))
$model->attributes=$_GET['User'];
$this->render('admin',array(
'model'=>$model,

您可以通过将CDataColumn
属性设置为数组,在filter
中指定自定义过滤器。它将导致下拉列表过滤器而不是文本字段过滤器。
示例:
<?php
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'user-grid',
'dataProvider' => $model->search(),
'filter' => $model,
'columns' => array(
'email',
array(
'name' => 'status',
'filter' => array(
'processed' => 'Processed',
'waiting' => 'Waiting',
),
),
array(
'class' => 'CButtonColumn',
'template' => '{view}{update}',
'buttons' => array(
'view' => array(
)
),
),
),
));

型号:
class User extends CActiveRecord {
const STATUS_PROCESSED = 'processed';
const STATUS_WAITING = 'waiting';
public static function getStatusList(){
return array(
self::STATUS_PROCESSED => 'Processed',
self::STATUS_WAITING => 'Waiting',
);
}
public function getStatusValue(){
$list = self::getStatusList();
return array_key_exists( $this->status, $list ) ? $list[ $this->status ] : 'Undefined';
}
}
查看:
$this->widget('zii.widgets.grid.CGridView', array(
// other params
'columns' => array(
// other columns
array(
'name' => 'status',
'value' => '$data->getStatusValue()',
'filter' => User::getStatusList(),
),
)
));
