在Sonata管理员列表视图中显示不同的实体

Question

I've got this entity, which contains entityName property and entityId property:

    /**
     * @var string
     *
     * @ORM\Column(name="entityName", type="string", length=255)
     */
    private $entityName;

    /**
     * @var integer
     * @ORM\Column(name="entityId", type="integer")
     */
    private $entityId;

Instead of showing this entity using __toString() function, I wanted to actually return the entity with name and id. and show that in sonata admin list view.

for now, here is __toString :

public function __toString()
{
    return $this->entityName . ":" . $this->entityId;
}

which should return something like:

public function __toString()
{
    return $em->getRepository($this->entityName)->find($this->entityId);
}

I hope that I've described my problem well. tnx

One workaround is to use custom list block for sonata.

1. create a new twig filter called entityFilter , this filter will convert FQCN of an sonata admin object to a readable route name generated by sonata. like admin_blablabla_show :

    public function entityFilter($entityName) { $str = str_replace('\\\\', '_', $entityName); $str = str_replace('Bundle', '', $str); $str = str_replace('_Entity', '', $str); $str = 'Admin' . $str . '_Show'; return strtolower($str); } public function getName() { return 'my_extension'; } 

2. in you admin class, set the template of the desired field to a new twig template:

     ->add('orderItems', null, array( 'template' => 'AcmeBundle::order_items_list.html.twig' )) 

3. And in your new twig template (order_items_list.html.twig):

    {% extends 'SonataAdminBundle:CRUD:base_list_field.html.twig' %} {% block field %} <div> {% for item in object.orderItems %} {% if entity(item.entityName) == 'admin_first_entity_show' %} {% set foo = 'Apple ID' %} {% elseif entity(item.entityName) == 'admin_second_entity_show' %} {% set foo = 'Device Accessory' %} {% else %} {% set foo = 'Not defiend' %} {% endif %} <a target="_blank" class="btn btn-default btn-xs" href="{{ path(entity(item.entityName), {'id': item.entityId}) }}"><i class="fa fa-external-link"></i> {{ foo }}</a> {% endfor %} </div> {% endblock %}
