Symfony 4.1 - sonata admin - 覆盖单个显示映射器项目的模板

Question

我正在尝试像这样覆盖显示操作的单个模板：

public function configureShowFields(ShowMapper $showMapper)
    {
        $showMapper
            ->add('smsShipments',null, array(
                'template' => 'sms_shipment_list.html.twig'
            ))    
    }

但我收到这样的警告：

An error occured trying to load the template "sms_shipment_list.html.twig" for the field "smsShipments", the default template "@SonataAdmin/CRUD/base_show_field.html.twig" was used instead.

因此错误如下：

Uncaught PHP Exception Twig_Error_Runtime: "An exception has been thrown during the rendering of a template ("Warning: nl2br() expects parameter 1 to be string, object given")." at C:\xampp_7\htdocs\project_name\vendor\sonata-project\admin-bundle\src\Resources\views\CRUD\base_show_field.html.twig line 23

这在 Symfony 3.1 中非常有效。您能否提供替代解决方案来覆盖单个管理员的显示元素或显示操作？

Answer 1

从这个 SonataAdminBundle guide on the official Symfony 4.x documentation 中提取，我发现您需要在 templates/Namespace/sms_shipment_list.html.twig 中使用您的树枝模板。

然后，然后在选项参数中将其引用为@App/Namespace/sms_shipment_list.html.twig。

像这样，然后：

public function configureShowFields(ShowMapper $showMapper)
{
    $showMapper
        ->add('smsShipments',null, array(
            'template' => '@App/Namespace/sms_shipment_list.html.twig'
        ))    
}
