Question

我使用stwe / DatatablesBundle进行symfony 2（http://github.com/stwe/DatatablesBundle）（稳定版本v0.6.1）并收到以下错误：

捕获致命错误：参数1传递给 SG \ DatatablesBundle \ DATATABLE \查看\ AbstractDatatableView :: __结构（）必须是Symfony \ Bundle \ TwigBundle \ TwigEngine的实例，无给予，召唤 G：\服务器\ WWW \ bongoapp \程序\缓存\ dev的\ appDevDebugProjectContainer.php 在第418行并定义

我已尝试按照here的答案，但这对我不起作用。我究竟做错了什么？代码如下并提前感谢：

生成的数据表类：

namespace Bbd\BongoAppBundle\Datatables;

use Sg\DatatablesBundle\Datatable\View\AbstractDatatableView;

/**
 * Class ArtistDatatable
 *
 * @package Bbd\BongoAppBundle\Datatables
 */
 class ArtistDatatable extends AbstractDatatableView
{
/**
 * {@inheritdoc}

public function buildDatatableView()
{
    $this->getFeatures()
                    ->setServerSide(true)
                    ->setProcessing(true);

            $this->getAjax()->setUrl($this->getRouter()->generate('artist_results'));

    $this->setStyle(self::BOOTSTRAP_3_STYLE);


    $this->getColumnBuilder()
            ->add('id', 'column', array('title' => 'Id',))
            ->add('name', 'column', array('title' => 'Name',))
            ->add('bangla_name', 'column', array('title' => 'Bangla_name',))

            ->add('graphics.poster', 'column', array('title' => 'Graphics Poster',))
            ->add('graphics.feature', 'column', array('title' => 'Graphics Feature',))
            ->add('graphics.gallery', 'column', array('title' => 'Graphics Gallery',))
            ;
}

/**

public function getEntity()
{
    return 'Bbd\BongoAppBundle\Entity\Artist';
}

/**

public function getName()
{
    return 'artist_datatable';
}
}

控制器

public function indexAction()
{
    $postDatatable = $this->get("bbd_datatables.artist");

    return array(
        "datatable" => $postDatatable,
    );
}

public function indexResultsAction()
{
    /**
     * @var \Sg\DatatablesBundle\Datatable\Data\DatatableData $datatable
     */
    $datatable = $this->get("bbd_datatables.datatable")->getDatatable($this->get("bbd_datatables.artist"));



    return $datatable->getResponse();
}

services.yml

  bbd_datatables.artist:
     class: Bbd\BongoAppBundle\Datatables\ArtistDatatable
     tags:
        - { name: bbd.datatable.view }

和 index.html.twig

{% block content_content %}
{{ datatable_render_html(datatable) }}
{% endblock %}
{% block javascripts %}
{{ parent() }}
{{ datatable_render_js(datatable) }}
{% endblock %}

Answer 1

好像你使用了错误的标签。

bbd_datatables.artist:
   class: Bbd\BongoAppBundle\Datatables\ArtistDatatable
   tags:
      - { name: sg.datatable.view }

查找： https://github.com/stwe/DatatablesBundle/blob/master/Resources/doc/example.md#step-3-registering-your-datatables-class-as-a-service

Answer 2

我可以通过在配置中使用parent参数来解决这个问题：

bbd_datatables.artist:
    class: Bbd\BongoAppBundle\Datatables\ArtistDatatable
    parent: sg_datatables.datatable.abstract
    tags:
        - { name: sg.datatable.view }

这会提取AbstractDatatableView所需的参数声明。
