如何CACHE查询/查找结果与PAGINATION CakePhp 2.x？ [英] How to CACHE query/find results with PAGINATION CakePhp 2.x?

问题描述

我在CakePhp中使用 Cache :: read（）， Cache :: write（）

I use Cache::read(), Cache::write() in CakePhp to cache queries.

如何更新paginator params或CACHE整个分页器？

缓存查询结果，但是如何缓存 $ this-> Paginator-> params（）？

It easy to cache query result but how to cache $this->Paginator->params() too?

strong>我尝试过到 Cache :: write（） $ this-> Paginator-& code>但如何在缓存后修改 $ this-> Paginator-> params（）？当我做某事时：
...

I've tried to Cache::write() $this->Paginator->params() but how to modify $this->Paginator->params() after caching? When I do someting like: ...

$this->Paginator->params['paging'][$model] = $paginator_params;

...
我收到通知：

... I've got notice:

Indirect modification of overloaded element of CakeRequest has no effect

我可以在哪里和何时重写PAGINATOR参数/设置缓存的参数？

谢谢。

推荐答案

您需要缓存 $ this-> request-> params ['paging'] array

You need to cache $this->request->params['paging'] array.

您必须将Paginator Helper添加到 $ helpers 数组。

And you have to add Paginator Helper to $helpers array. If you don't, beforeRender method of Paginator helper won't be invoked and paging links will be broken.

$page = !isset($this->request->named['page']) ? '1' : $this->request->named['page'];
$products = Cache::read('my_unique_cache_id_' . $page, 'query');  
$paging = Cache::read('my_unique_cache_id_paging_' . $page, 'query');

if ($products && $paging) {
    $this->set('products', $products);
    $this->request->params['paging'] = $paging;

}else{
    $products = $this->paginate('Product');
    Cache::write('my_unique_cache_id_paging_' . $page, $this->request->params['paging'], 'query');
    Cache::write('my_unique_cache_id_' . $page, $products, 'query');
    $this->set('products', $products);
}
