Displaying item id in sonata admin bundle

Question

I created an admin interface using sonatadminbundle, it works fine & can add items & display them, but I also need to display the item id set by default (set as auto-increment) in the admin interface, how can I do that?

Answer 1

you can do that using the __toString() method in the Entity (in your example Category) like:

function __toString()
{
    return $this->getId().' - '.$this->getName();
}

Answer 2

Add id in $listMapper in your Acme/DemoBundle/Admin/somethingAdmin.php file:

protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->addIdentifier('name')
            ->add('id')
        ;
    }
