关于php：在渲染模板的过程中抛出了异常(“A”__toString()”

An exception has been thrown during the rendering of a template (“A “__toString()”

我在继续操作时遇到了这个错误
tutorial.symblog.co.uk[第 4 部分]–评论模型：添加评论、Doctrine 存储库和迁移]

An exception has been thrown during the rendering of a template (“A”__toString()” method was not found on the objects of type”Blogger//BlogBundle//Entity//Blog” passed to the choice field. To read a custom getter instead, set the option”property” to the desired property path.”)
in BloggerBlogBundle:Blog:show.html.twig at line 23.

有人对此有所了解吗？

// src/Blogger/BlogBundle/Entity/Blog.php
namespace Blogger//BlogBundle//Entity;
use Doctrine//ORM//Mapping as ORM;
use Doctrine//Common//Collections//ArrayCollection;
/**
* @ORM//Entity(repositoryClass="Blogger//BlogBundle//Entity/
epository//BlogRepositorya€?a€?")
* @ORM//Table(name="blog")
* @ORM//HasLifecycleCallbacks()
*/
class Blog {
//……….
public function __toString() {
return $this->getTitle();
}
}

只需在 Blog 实体中添加 __toString() 方法
