Zend_Paginator 和缓存.如何读取已发送到缓存的数据 [英] Zend_Paginator and cache. How can I read the datas that I have sent to cache

问题描述

我将数据注册到缓存，然后看到以下内容:

I register the data to cache and I see the foliowing :

zend_cache---Zend_Paginator_1_42242d5fa3c4e4b7758810c276163e8a

zend_cache---Zend_Paginator_1_42242d5fa3c4e4b7758810c276163e8a

但我看不懂.

$request = $this->getRequest();
 $q = new Model();
 $paginator = Zend_Paginator::factory($q->fetchAll());
 $paginator->setCurrentPageNumber($request->getParam('p')); 
 $paginator->setItemCountPerPage(40);
 $this->view->q = $paginator;

 $fO = array('lifetime' => 3600, 'automatic_serialization' => true);
 $bO = array('cache_dir'=> APPLICATION_PATH . '/cache/');
 $cache = Zend_cache::factory('Core', 'File', $fO, $bO);
 Zend_Paginator::setCache($cache);

推荐答案

检查是否启用了 DB Profiler.似乎 DB 分析器和 Zend_Paginator_Adapter_DbTableSelect 之间存在冲突.

Check to see if DB profiler is enabled. It seems that there is a conflict between DB profiler and Zend_Paginator_Adapter_DbTableSelect.

我还创建了一个扩展 Zend_Paginator 的新分页器类，并且我修改了 getItemsByPage 函数.

I've also created a new Paginator class that extends Zend_Paginator and I've modified getItemsByPage function.

$offset = ($pageNumber - 1) * $this->getItemCountPerPage();
$items = $this->_adapter->getItems($offset, $this->getItemCountPerPage());

这两行代码应该在开头添加，在$pageNumber = $this->normalizePageNumber($pageNumber)之后.

These two lines of code should be added at the beggining, after $pageNumber = $this->normalizePageNumber($pageNumber).
