問題描述

我想在 zend_paginator 中使用學說

i want to use doctrine with zend_paginator

這里有一些示例查詢:

$allArticleObj =$this->_em->getRepository('文章');$qb = $this->_em->createQueryBuilder();

$allArticleObj = $this->_em->getRepository('Articles'); $qb = $this->_em->createQueryBuilder();

    $qb->add('select', 'a')
            ->add('from', 'Articles a')
            ->setFirstResult(0)
            ->setMaxResults(5);

是否有任何示例代碼表明我們可以為 Dotct 2 查詢構建器編寫 zend_paginator 適配器?

is there any example code to show we can write a zend_paginator adapter for doctrine 2 query builder?

推薦答案

結果當然是你必須實現Zend_Paginator_Adapter_Interface，這實質上意味著實現兩個方法:

The upshot, of course, is that you have to implement the Zend_Paginator_Adapter_Interface, which essentially means implementing the two methods:

count()

getItems($offset, $perPage)

您的適配器將接受 Doctrine 查詢作為構造函數參數.

Your adapter would accept the Doctrine query as a constructor argument.

原則上，getItems() 部分實際上很簡單.只需將 $offset 和 $perPage 限制添加到查詢中 - 正如您在示例中所做的 - 并執行查詢.

In principle, the getItems() part is actually straightforward. Simply, add the $offset and $perPage restrictions to the query - as you are doing in your sample - and execute the query.

在實踐中，count() 業務往往很棘手.我會遵循 Zend_Paginator_Adapter_DbSelect 的例子，用它們的 Doctrine 類似物替換 Zend_Db 操作.

In practice, it's the count() business that tends to be tricky. I'd follow the example of Zend_Paginator_Adapter_DbSelect, replacing the Zend_Db operations with their Doctrine analogues.
