在Symfony2中使用Pagerfanta进行分页的正确方法是什么

Question

I have read that Pagerfanta is the pagination plugin of choice for Symfony2, but I am having some trouble getting it to work correctly. I have downloaded the code for pagerfanta and PagerfantaBundle and installed them as described in the WhiteOctober Github readme file and in this tutorial . I'm pretty sure the code in my controller is okay, but there is something wrong with my template file.

My controller code:

public function indexAction($page =  null)
{
    ...
    $query = $em->createQuery('SELECT something FROM some_table');
    $adapter = new DoctrineORMAdapter($query);
    $pager =  new Pagerfanta($adapter);
    $pager->setMaxPerPage(10);
    if (!$page)    $page = 1;
    try  {
        $pager->setCurrentPage($page);
    }
    catch(NotValidCurrentPageException $e) {
      throw new NotFoundHttpException('Illegal page');
    }
    return $this->render('MyBundle:MyEntity:index.html.twig', array(
        'pager' => $pager,
    ));
}

In my template:

...
<table>
  {% for object in pager.currentPageResults %}
    <tr>
      <td>{{ object.attribute1 }}</td>
      <td>{{ object.attribute2 }}</td>
      <td>{{ object.attribute3 }}</td>
    </tr>
  {% endfor %}
</table>

{% if pager.haveToPaginate %}
  {{ pagerfanta(pager) }}
{% endif %}

When I go to the page, I get a list of the first 10 objects. However,the rendering of the pager is just PreviousNext as one word (not links and no pages 1, 2, 3, etc).

If I add ?page=2 to the URL, it doesn't display the next 10 items in the list.

I didn't change the route from what is was before I added the pagination code because the documentation says:

The routes are generated automatically for the current route using the variable "page" to propagate the page number.

... but I wonder if incorrect routing is part of the problem. Assuming this is the case, I'm not sure how to proceed with this.

I have been unable to find any instructions other the sources I have linked to above, so it would be great if someone who has implemented this successfully could share the details of how they did it.

Answer 1

I think your application doesn't know how to parse ?page=2 to the controller action.

Include a {page} in your route (as @AdrienBrault replied), which you wish to have pagination.

like this:

my_index:
  pattern:  /{page}
  defaults: { _controller: MyTestBundle:Object:index, page: 1 }
  requirements:
    _method:  GET
    page: \d+

PagerFantaBundle will (I guess) try to guess the correct route.

Worked for me.

Answer 2

我不得不在我的路由中使用'currenPage'而不是'page'，我找到了一种方法：

{{ pagerfanta(pager, 'my_pager_view', {'pageParameter':'[currentPage]'}) }}
