(“参数“"路由“"必须匹配“[^/]++"(“"给定)使用pagerfanta [英] ("Parameter "" for route "" must match "[^/]++" ("" given) using pagerfanta

问题描述

我正在尝试让 PagerFanta 工作来分页我的数据.我可以查看第一页，并且 pagerfanta 部分中生成的代码会生成所有正确的链接，但是当我单击这些相应链接中的任何一个时，标题中出现异常.似乎 pagerfanta twig 函数在生成路由时没有给出正确的参数.

I'm attempting to get PagerFanta working to page my data. I can view the first page and the generated code in the pagerfanta portion generates all the correct links, however when I click on any of those corresponding links I get the exception in the title. It seems like the pagerfanta twig function is not giving the correct parameter when generating the routes.

控制器动作:

/**
     * @Route("/people/{page}", name="view_people")
     * @Template("AppBundle:Default:people.html.twig")
     */
    public function viewPeopleAction($page)
    {
        $people = $this->getDoctrine()
            ->getRepository('AppBundle\Entity\Person')
            ->findAll();
        $adapter = new ArrayAdapter($people);
        $pager = new Pagerfanta($adapter);
        $pager->setMaxPerPage(45);

        try {
            $pager->setCurrentPage($page);
        } catch(NotValidCurrentPageException $e) {
            throw new NotFoundHttpException();
        }

        return array('pager' => $pager);
    }

树枝页:

{% extends '::base.html.twig' %}

{% block title %}{% endblock %}

{% block body %}
    <table>
  {% for object in pager.currentPageResults %}
    <tr>
      <td><a href="{{ path('view_person', {'personid': object.id}) }}">{{ object.name }}</a></td>
    </tr>
  {% endfor %}
</table>

{% if pager.haveToPaginate %}
  {{ pagerfanta(pager, "twitter_bootstrap_translated", {"routeName": "view_people", "pageParameter": "[page]"} ) }}
{% endif %}
{% endblock body %}
{% block javascripts %}
{% endblock %}

完全错误:

An exception has been thrown during the rendering of a template ("Parameter "page" for route "view_people" must match "[^/]++" ("" given) to generate a corresponding URL.") in AppBundle:Default:people.html.twig at line 15.

我的代码有什么问题导致了这个错误?非常感谢任何和所有帮助.

What is wrong with my code that is causing this error? Any and all help greatly appreciated.

推荐答案

page 参数需要设置一个默认值，当页面为一页时会省略这个参数:

You need to set a default value for the page parameter as this one will be omitted when the page is one:

/**
 * @Route("/people/{page}", name="view_people", defaults={"page"=1})
 * @Template("AppBundle:Default:people.html.twig")
 */
public function viewPeopleAction($page)
{
    // ...
}
