Display sonata mongodb admin bundle - mongodb

Question

i'm adding Sonata mongoDB admin Bundle in my project, after doing all the config, it seems that the bundle works fine but there is a problem it does not display the list of the document which is supposed to display.
when i go to /admin i find the sonata admin template but i got it empty. here is my config.yml :
sonata_block:
default_contexts: [cms]
blocks:
# Enable the SonataAdminBundle block
sonata.admin.block.admin_list:
contexts: [admin]
sonata_doctrine_mongo_db_admin:
templates:
form:
- SonataDoctrineMongoDBAdminBundle:Form:form_admin_fields.html.twig
filter:
- SonataDoctrineMongoDBAdminBundle:Form:filter_admin_fields.html.twig
types:
list:
array: SonataAdminBundle:CRUD:list_array.html.twig
boolean: SonataAdminBundle:CRUD:list_boolean.html.twig
date: SonataAdminBundle:CRUD:list_date.html.twig
time: SonataAdminBundle:CRUD:list_time.html.twig
datetime: SonataAdminBundle:CRUD:list_datetime.html.twig
text: SonataAdminBundle:CRUD:base_list_field.html.twig
trans: SonataAdminBundle:CRUD:list_trans.html.twig
string: SonataAdminBundle:CRUD:base_list_field.html.twig
smallint: SonataAdminBundle:CRUD:base_list_field.html.twig
bigint: SonataAdminBundle:CRUD:base_list_field.html.twig
integer: SonataAdminBundle:CRUD:base_list_field.html.twig
decimal: SonataAdminBundle:CRUD:base_list_field.html.twig
identifier: SonataAdminBundle:CRUD:base_list_field.html.twig
show:
array: SonataAdminBundle:CRUD:show_array.html.twig
boolean: SonataAdminBundle:CRUD:show_boolean.html.twig
date: SonataAdminBundle:CRUD:show_date.html.twig
time: SonataAdminBundle:CRUD:show_time.html.twig
datetime: SonataAdminBundle:CRUD:show_datetime.html.twig
text: SonataAdminBundle:CRUD:base_show_field.html.twig
trans: SonataAdminBundle:CRUD:show_trans.html.twig
string: SonataAdminBundle:CRUD:base_show_field.html.twig
smallint: SonataAdminBundle:CRUD:base_show_field.html.twig
bigint: SonataAdminBundle:CRUD:base_show_field.html.twig
integer: SonataAdminBundle:CRUD:base_show_field.html.twig
decimal: SonataAdminBundle:CRUD:base_show_field.html.twig
and here is my admin.yml (i followed the documentation) :
services:
sonata.admin.question:
class: ATS\AdminBundle\Admin\questionAdmin
tags:
- { name: sonata.admin, manager_type: doctrine_mongodb, group: "Content", label: "Question" }
arguments:
- ~
- ATS\QuizzBundle\Document\Question
- ~
calls:
- [ setTranslationDomain, [ATSAdminBundle]]
and finally here is my questionAdmin class (until here i need only to show the list of my questions stored in the db) :
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Show\ShowMapper;
class questionAdmin extends Admin
{
// Fields to be shown on create/edit forms
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('question')
->add('weight')
// ->add('tags')
// ->add('commentsEnabled')
//add custom action links
->add('_action', 'actions', array(
'actions' => array(
'view' => array(),
'edit' => array(),
)
))
;
}
Any one have the solution plz ? thank you
