如何处理 SonataAdminBundle 列表视图中的每个实体? [英] How to process each entity in SonataAdminBundle list view?

问题描述

如何将一些代码应用于管理员列表视图中显示的每个实体?

How to apply some code to each entity being displayed in Admin's list view?

例如，如果我有一个 TagManager 并且需要为每个显示的实体加载标签，我该怎么做?是否有一种方法可以在实体的 Admin 中进行覆盖，或者我可以绑定到某个列表表单事件吗?我找不到这样做的地方.

For example, if I have a TagManager and need to load tags for each entity being displayed, how do I do that? Is there a method to override in entity's Admin or can I bind to some list form event? I could not find a place to do that.

我不想绑定到实体的 onLoad 事件.

I don't wan't to bind to entity's onLoad event.

推荐答案

在您的 entityAdminController 中:

In your entityAdminController :

public function listAction()
{
    if (false === $this->admin->isGranted('LIST')) {
        throw new AccessDeniedException();
    }

    $datagrid = $this->admin->getDatagrid();
    $formView = $datagrid->getForm()->createView();

    foreach($datagrid->getResults() as $object)
    {
        //do what you want with $object
    }

    // set the theme for the current Admin Form
    $this->get('twig')->getExtension('form')->renderer->setTheme($formView, $this->admin->getFilterTheme());

    return $this->render($this->admin->getTemplate('list'), array(
        'action'   => 'list',
        'form'     => $formView,
        'datagrid' => $datagrid
    ));
}
