Question

我已经遵循了这个：http://sonata-project.org/bundles/admin/master/doc/cookbook/recipe_sortable_listing.html

当我试图列出我的物品时，我得到了这个：

PHP Fatal error:  Call to a member function getLastPosition() on a
non-object in
/home/tirengarfio/workspace/javierperezpla/src/Placas/FrontendBundle/Admin/ColumnaAdmin.php
on line 45, referer:
http://javierperezpla/app_dev.php/admin/placas/frontend/columna/3/edit

这是我的代码：

namespace Placas\FrontendBundle\Admin;

use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;

class ColumnaAdmin extends Admin
{
    public $last_position = 0;

    private $container;
    private $positionService;

    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('name', 'text', array('label' => 'Nombre', 'required' => false))
            ->add('position', 'text', array('label' => 'Posición', 'required' => false))
        ;
    }

     public function setContainer(\Symfony\Component\DependencyInjection\ContainerInterface $container)
     {

         $this->container = $container;
     }

     public function setPositionService(\Pix\SortableBehaviorBundle\Services\PositionHandler $positionHandler)
     {
  /*It is not entering here*/
         $this->positionService = $positionHandler;
     }

     protected $datagridValues = array(
         '_page' => 1,
         '_sort_order' => 'ASC',
         '_sort_by' => 'position',
     );

    // Fields to be shown on lists
    protected function configureListFields(ListMapper $listMapper)
    {
        /*var_dump($this->postionService);die; HERE I GET NULL*/
        $this->last_position = $this->positionService->getLastPosition($this->getRoot()->getClass());
        $listMapper
            ->addIdentifier('name')
            ->add('enabled')
            ->add('_action', 'actions', array(
                'actions' => array(
                'move' => array('template' => 'PixSortableBehaviorBundle:Default:_sort.html.twig'),
        )));
    }

    protected function configureRoutes(\Sonata\AdminBundle\Route\RouteCollection $collection)
    {
        $collection->add('move', $this->getRouterIdParameter() . '/move/{position}');
    }
}

您应该致电setPositionService()：

sonata.admin.columna:
    class: Placas\FrontendBundle\Admin\ColumnaAdmin
    tags:
        - { name: sonata.admin, manager_type: orm, group: "Contenido web", label: "Columna" }
    arguments:
        - ~
        - Placas\FrontendBundle\Entity\Columna
        - 'PixSortableBehaviorBundle:SortableAdmin' # define the new controller via the third argument
    calls:
        - [ setTranslationDomain, [PlacasFrontendBundle]]
        - [ setPositionService, [@pix_sortable_behavior.position]]

pix_sortable_behavior.position必须是\Pix\SortableBehaviorBundle\Services\PositionHandler的实例。

事实上，您提供的文档是：

在admin.yml中添加以下调用

 - [ setContainer, [ @service_container ] ]
 - [ setPositionService, [@pix_sortable_behavior.position]]
