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？

只需在 Blog 实体中添加 __toString() 方法
