How to retrieve subject in Sonata configureListFields? - symfony

Question

I use Sonata Admin Bundle in my Symfony project and created an ArticleAdmin class for my Article entity.
In the list page, I added some custom actions to quickly publish, unpublish, delete & preview each article.
What I want to do is to hide publish button when an article is already published & vice versa.
To do this, I need to have access to each object in method configureListFields(). I would do something like this:
protected function configureListFields(ListMapper $listMapper)
{
$listMapper->add('title');
// ...
/** #var Article article */
$article = $this->getSubject();
// Actions for all items.
$actions = array(
'delete' => array(),
'preview' => array(
'template' => 'AppBundle:ArticleAdmin:list__action_preview.html.twig',
),
);
// Manage actions depending on article's status.
if ($article->isPublished()) {
$actions['draft']['template'] = 'AppBundle:ArticleAdmin:list__action_draft.html.twig';
} else {
$actions['publish']['template'] = 'AppBundle:ArticleAdmin:list__action_preview.html.twig';
}
$listMapper->add('_actions', null, array('actions' => $actions));
}
But $this->getSubjet() always returns NULL. I also tried $listMapper->getAdmin()->getSubject() and many other getters but always the same result.
What am I doing wrong ?
Thanks for reading & have a good day :)

You can do the check directly in the _action template, as you can access the current subject.
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->add('title')
->add('_action', 'actions', array(
'actions' => array(
'delete' => array(),
'preview' => array(
'template' => 'AppBundle:ArticleAdmin:list__action_preview.html.twig',
),
'draft' => array(
'template' => 'AppBundle:ArticleAdmin:list__action_draft.html.twig',
),
'publish' => array(
'template' => 'AppBundle:ArticleAdmin:list__action_publish.html.twig',
),
))
;
}
And for example in AppBundle:ArticleAdmin:list__action_draft.html.twig, you can check your condition :
{% if object.isPublished %}
your html code
{% endif %}
