Yii 打造带有缓存功能的AR

继承AR类 重写 findByPk方法为pk  还有afterSave afterDelete

通过对象主键缓存其属性  在insert update delete 操作时候 都会自动更新缓存
还是挺方便的

public function afterDelete()

{

    $cache = $this->getCache();

    $cache->cdelete($this->cacheGroup(), $this->getPKValue());

    parent::afterDelete();

}



public function cacheGroup()

{

    return $this->tableName();

}



public function pk($value)

{

    $attr = $this->getCache()->cget($this->cacheGroup(), $value);

    if (!$attr) {

        $model = $this->findByPk($value);

        if ($model) {

            $attr = $model->getAttributes();

        }

        $this->getCache()->cset($this->cacheGroup(), $value, $attr = !empty($attr) ? $attr :

            MMemcache::NULL_VAR);

    } elseif (MMemcache::isNULL($attr)) {

        $model = null;

    } else {

        $model = $this->populateRecord($attr);

    }

    return $model;

}



public function afterSave()

{

    $cache = $this->getCache();

    $cache->cdelete($this->cacheGroup(), $this->getPKValue());

    if ($this->getIsNewRecord()) {

        $cache->cadd($this->tableName(), $this->getPKValue(), $this->getAttributes());

    } else {

        $cache->cadd($this->tableName(), $this->getPKValue(), $this->getAttributes());

    }

    parent::afterSave();

}

MMemcache 自己的情况实现

大家有好思路 多分享哦  这样Yii才会越来越强大
