Sonata Admin Bundle: show total count of collection on list view

Question

Is there any way to show total count of collection on list view? Imagine that there is a user that can have many links. How can I show total links count on list view?

Answer 1

Yes you can show the total count of links for each user, i assume you have arraycollection of links defined in your user entity, define a property named as $totalLinks and in getter of that property return count of links something like below

class User{

    public $totalLinks;
    public function getTotalLinks(){
        return count($this->getLinks());
    }
}

and then in your configureListFields() you can add $totalLinks property

protected function configureListFields(ListMapper $list)
{
    $list
    ->add('...')
    ->add('...')
    ->add('totalLinks');
}
