Sonata Admin - Disable list view - symfony

Question

I'm facing a problem with Sonata Admin. Is there a way to disable the "list view" ? I would like to fetch the first entity in the database and to go on it when clicking on the link in the sidebar. But not for all entry.
Is there a clean way to do it ? (I have the idea to check the entity in a custom controller, and to redirect to list view or edit view depending on the entity, but that's not really clean)

Answer 1

If you want to do a custom query for your list view, you could override the createQuery method in your Admin class like this :
class EntityAdmin
{
public function createQuery($context = 'list')
{
$query = parent::createQuery($context);
$query->andWhere(
$query->expr()->eq($query->getRootAlias() . '.id', ':id')
);
$query->setParameter('id', 1);
return $query;
}
}
You will have only your first entity in your list view.
UPDATE
You could override the standard_layout.html.twig to change the link in your sidebar :
First you need to set where your template is located:
app/config/config.yml
sonata_admin:
templates:
layout: ApplicationSonataAdminBundle::standard_layout.html.twig
Change the behaviour of the sidebar, for Sonata Admin 2.3 this is how you do it :
src/Application/Sonata/AdminBundle/Resources/Views/standard_layout.html.twig l.224
<ul class="treeview-menu{% if active %} active{% endif %}">
{% for admin in group.items %}
{% if admin.code == 'sonata.admin.entity' and
admin.hasroute('edit') and
admin.isGranted('EDIT') %}
<li{% if app.request.get('_sonata_admin') == admin.code %} class="active"{% endif %}><i class="fa fa-angle-double-right"></i> {{ admin.label|trans({}, admin.translationdomain) }}</li>
{% else %}
{% if admin.hasroute('list') and admin.isGranted('LIST') %}
<li{% if app.request.get('_sonata_admin') == admin.code %} class="active"{% endif %}><i class="fa fa-angle-double-right"></i> {{ admin.label|trans({}, admin.translationdomain) }}</li>
{% endif %}
{% endif %}
{% endfor %}
</ul>
You must change 'sonata.admin.entity' by the identifier of your admin service.
Also if you want to remove access to the list you should add in your Admin class
use Sonata\AdminBundle\Route\RouteCollection;
class EntityAdmin
{
protected function configureRoutes(RouteCollection $collection)
{
$collection->remove('list');
}
}
