Symfony 5 错误，我的属性访问有问题答案

【问题标题】：Symfony 5 Error, I have problem on properties accessSymfony 5 错误，我的属性访问有问题
【发布时间】：2022-08-19 05:22:50
【问题描述】：

我收到此错误，但我不知道问题出在哪里

属性 \"image_medecin\" 和方法之一 \"image_medecin()\"、\"getimage_medecin()\"/\"isimage_medecin()\"/\"hasimage_medecin()\" 或 \"__call() \" 存在并在类 \"App\\Entity\\Medecin\" 中具有公共访问权限

问题是我想在视图中显示医生图像 <模板\\medecin\\show.html.twig> 我正在读取一个对象医学作为医生的数据，问题是它的所有属性都显示了，但是image_medecin财产不，我不知道为什么，请大家帮忙，我被困了几个小时！

【解决方案1】：

错误非常明确

既不是属性“image_medecin”也不是其中一种方法 "image_medecin()", “getimage_medecin()”/“isimage_medecin()”/“hasimage_medecin()”或 “__call()” 存在并在“App\Entity\Medecin”类中具有公共访问权限

Twig 尝试访问对象medecin 中的属性image_medecin，但它是私有的，无法直接访问。

所以它尝试了image_medecin()、getimage_medecin、isimage_medecin()、hasimage_medecin()，最后尝试了魔术方法__call()。

您可以直接在树枝模板中使用正确的方法：
<img src="{{ medecin.getImageMedecin() ? "asset('assets/Uploads/medecin/')" ~ medecin.getImageMedecin() : "https://img.freepik.com/free-photo/doctor-with-his-arms-crossed-white-background_1368-5790.jpg?w=2000"}}" alt="Medecin Image">
