Symfony2 - SonataAdmin - Empty admin_list block

我一直在尝试安装SonataAdminBundle。我想我遵循了文档，加上我读了一些关于它的博客。但我做不到。

当转到admin/dashboard页面时，我看到了Sonata标题，我可以看到右边的Sonata.block.service.text和Sonata.bock.service.rss，但admin_list块中没有任何东西=>我看不到我的实体。

以下是我的设置方式。我可能忘了什么？这是app/config/config.yml

- { resource: parameters.yml }
- { resource: security.yml }
- { resource: ../../src/Pierre/TennisBundle/Resources/config/admin.yml }

我的管理员类

namespace Pierre'TennisBundle'Admin;
use Sonata'AdminBundle'Admin'Admin;
use Sonata'AdminBundle'Datagrid'ListMapper;
use Sonata'AdminBundle'Datagrid'DatagridMapper;
use Sonata'AdminBundle'Form'FormMapper;
use Pierre'TennisBundle'Entity'Tennismen;
class TennismenAdmin extends Admin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('name')
               ;
    }
    protected function configureDatagridFilters(DatagridMapper $datagridMapper)
    {
        $datagridMapper
            ->add('name')
               ;
    }
    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->addIdentifier('name')
                ;
    }
}

我的控制器：

namespace Pierre'TennisBundle'Controller;
use Sonata'AdminBundle'Controller'CRUDController as Controller;
class TennismenAdminController extends Controller
{
}

我的服务：

# TennisBundle/Resources/config/admin.yml
services:
    pierre.tennis.admin.tennismen:
        class: Pierre'TennisBundle'Admin'TennismenAdmin
        tags:
            - { name: sonata.admin, manager_type: orm, group: sonata_page, label: Blog }
        arguments: [null, Pierre'TennisBundle'Entity'Tennismen, PierreTennisBundle:TennismenAdmin]

所以我想我尊重导游。。。但我在仪表板上看不到我的实体Tennismen。
