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(); } } |

tutorial.symblog.co.uk/docs/… // src/Blogger/BlogBu??ndle/Entity/Blog.php 命名空间 Blogger\\\\\\\\BlogBu??ndle\\\\\\\\Entity;使用 Doctrine\\\\\\\\ORM\\\\\\\\Mapping 作为 ORM；使用 Doctrine\\\\\\\\Common\\\\\\\\Collections\\\\\\\\ArrayCollection; /** * @ORM\\\\\\\\Entity(repositoryClass=”Blogger\\\\\\\\BlogBu??ndle\\\\\\\\Entity\\\\
epos??itory\\\\\\\\BlogRepository??”) * @ORM\\\\\\\\Table(name=”blog”) * @ORM\\\\\\\\HasLifecycleCallbacks() */ class Blog { //.. …….. 公共函数 __toString() { return $this->getTitle(); } } - 这是我从这里 tutorial.symblog.co.uk/docs/… 找到的，我正在关注”视图”部分 thnx..
- @bartek 在下面为您提供了答案。那应该可以解决您的问题。
只需在 Blog 实体中添加 __toString() 方法
