我想缓存 CActiveDataProvider 实例的数据库结果。
没有缓存CActiveDataProvider？还是一切正常？
我在控制器的操作中准备数据提供程序，然后在 CGridView 中使用数据提供程序，稍后在某些视图中使用。
这是我的代码：
$criteria = new CDbCriteria;
$criteria->with = array('person', 'department', 'position', 'policy');
$criteria->condition='t.companyID=:companyID AND t.state = :state';
$criteria->params = array(':companyID'=>$companyID, ':state'=>VersionedActiveRecordState::ACTIVE);
$dataProvider = new CActiveDataProvider( Employee::model()->cache(2000,null), array(
'criteria' => $criteria,
'totalItemCount'=>200,
'sort' => array(
'defaultOrder' => 'person.lastName ASC, person.firstName ASC, person.patronymic ASC',
'attributes' => array(
'ID',
'code',
'grade',
'employeeFullName' => array(
'asc' => 'person.lastName ASC, person.firstName ASC, person.patronymic ASC',
'desc' => 'person.lastName DESC, person.firstName DESC, person.patronymic DESC',
),
'departmentTitle' => array(
'asc' => 'department.title ASC',
'desc' => 'department.title DESC',
),
'positionTitle' => array(
'asc' => 'position.title ASC',
'desc' => 'position.title DESC',
),
'scheduleTitle' => array(
'asc' => 'schedule.title ASC',
'desc' => 'schedule.title DESC',
),
'policyTitle' => array(
'asc' => 'policy.title ASC',
'desc' => 'policy.title DESC',
),
),
),
'pagination' => array(
'pageSize'=> Yii::app()->user->getState('employee_pageSize',Yii::app()->params['defaultPageSize']),
)
));
但无济于事：查询没有被缓存。
