Adding action in SonataAdminBundle - symfony

Question

I'm trying to add an action in sonata admin bundle. I changed my Admin class with :
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('id')
->add('name')
// add custom action links
->add('_action', 'actions', array(
'actions' => array(
'view' => array(),
'calculate' => array('template' => 'myappMyBundle:Admin:list__action_calculate.html.twig'),
'edit' => array(),
)
))
;
}
and
protected function configureSideMenu(MenuItemInterface $menu, $action, Admin $childAdmin = null)
{
if (!$childAdmin && !in_array($action, array('edit'))) {
return;
}
$admin = $this->isChild() ? $this->getParent() : $this;
$id = $admin->getRequest()->get('id');
$menu->addChild('calculate', array('uri' => 'http://google.com?id=' . $id));
}
and put a template called list__action_calculate.html.twig in src/myapp/MyBundle/Resources/views/Admin/ :
{% if admin.isGranted('EDIT', object) and admin.hasRoute('edit') %}
<a href="{{ admin.generateObjectUrl('calculate', object) }}" class="calculate_link" title="{{ 'action_calculate'|trans({}, 'SonataAdminBundle') }}">
<img src="{{ asset('bundles/sonataadmin/famfamfam/page_white_edit.png') }}" alt="{{ 'action_calculate'|trans({}, 'SonataAdminBundle') }}" />
</a>
{% endif %}
But i got this error from symfony :
An exception has been thrown during the rendering of a template
("unable to find the route `mysite.mybundle.admin.myentity.calculate`")
in "SonataAdminBundle:CRUD:list.html.twig"
What have i missed ?
Is there a clue in the documentation than this page of the Doc.

Finally got it !
In the admin class :
protected function configureRoutes(RouteCollection $collection)
{
$collection->add('calculate');
}
# Override to add actions like delete, etc...
public function getBatchActions()
{
// retrieve the default (currently only the delete action) actions
$actions = parent::getBatchActions();
// check user permissions
if($this->hasRoute('edit') && $this->isGranted('EDIT') && $this->hasRoute('delete') && $this->isGranted('DELETE'))
{
// define calculate action
$actions['calculate']= array ('label' => 'Calculate', 'ask_confirmation' => true );
}
return $actions;
}
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('id')
->add('name')
// add custom action links
->add('_action', 'actions', array(
'actions' => array(
'view' => array(),
'calculate' => array('template' => 'chemoinfoEdrugBundle:CRUD:list__action_calculate.html.twig'),
'edit' => array(),
)
))
;
}
and in admin controller :
public function batchActionCalculate(ProxyQueryInterface $selectedModelQuery)
{
...
}
and in /src/mysite/mybundle/Resources/views/CRUD :
{% if admin.isGranted('EDIT', object) and admin.hasRoute('edit') %}
<a href="{{ admin.generateObjectUrl('calculate', object) }}" class="calculate_link" title="{{ 'action_calculate'|trans({}, 'SonataAdminBundle') }}">
<img src="{{ asset('bundles/sonataadmin/famfamfam/calculator.png') }}" alt="{{ 'action_calculate'|trans({}, 'SonataAdminBundle') }}" />
</a>
{% endif %}
