使用Doctrine和ZF2进行分页

Question

我正在尝试使用ZF2和Doctrine实现分页.

我在这里尝试做的是从关联表中获取数据,让我们说'xyz'.

我的类别表在其自己的PK上进行一对多的自引用.我的catgories表有以下的feilds

• ID(PK)
• Created_at
• Category_id(自引用PK)

我的XYZ表让我们说它名为Name表

• ID(PK)
• CATEGORY_ID(FK)
• 名称
• 详情

这就是我想要获取数据的方法

      public function allSubcategories($id, $column, $order) {
 $repository = $this->entityManager->getRepository('Category\Entity\Category');
    $queryBuilder = $repository->createQueryBuilder('category');
    $queryBuilder->distinct();
    $queryBuilder->select('category');

    $queryBuilder->join('Category\Entity\CategoryName', 'category_name', 'WITH', 'category.id = category_name.category');
    $queryBuilder->orderBy("category.status");
    $q = $queryBuilder->getDql();
    return $query = $this->entityManager->createQuery($q);
}

在我的控制器中,这就是我在做的事情

      public function subcategoryAction() {

    ///////////////////////////InPut Params Given for the pagination
    $category_id = (int) $this->params()->fromRoute('id', 0);
    $page = (int) $this->params()->fromRoute('page', 0);
    $column = $this->params()->fromQuery('column');
    $order = $this->params()->fromQuery('order');



    $categoryModel = $this->getServiceLocator()->get('Category');
    $categoryModel->category = $category_id;


    $perPage = 10;
    $request = $this->getRequest();
    if ($request->isGet()) {
        $view = new ViewModel();
        $query = $categoryModel->allSubcategories($category_id, $column, $order);

        $paginator = new ORMPaginator($query);

        $paginator = new \Zend\Paginator\Paginator(new
                        \Zend\Paginator\Adapter\ArrayAdapter(array($paginator)));
        $paginator->setCurrentPageNumber($page);
        $paginator->setItemCountPerPage(2);

    }

    return array('id' => $category_id, 'view' => $paginator);
}

现在我没有得到实施分页的结果可以指导一下我错过的内容吗？

你在那里使用了错误的分页符.相反,你可以使用一个DoctrineORMModule(见DoctrineORMModule\Paginator\Adapter\DoctrinePaginator).

它可能不是很明显,但逻辑与你已写的类似:

use DoctrineORMModule\Paginator\Adapter\DoctrinePaginator as PaginatorAdapter;
use Doctrine\ORM\Tools\Pagination\Paginator as ORMPaginator;
use Zend\Paginator\Paginator as ZendPaginator;

$query = $categoryModel->allSubcategories($category_id, $column, $order);

$paginator = new ZendPaginator(new PaginatorAdapter(new ORMPaginator($query)));
