Symfony 5 錯誤，屬性訪問有問題

Question

我收到此錯誤，我不知道問題出在哪里

屬性“image_medecin”和方法之一“image_medecin()”、“getimage_medecin()”/“isimage_medecin()”/“hasimage_medecin()”或“__call()”都不存在並且在 class“App\實體\醫學”

問題是我想在視圖中顯示醫生圖像 < templates\medecin\show.html.twig > 我正在從 ZA8CFDE6331BD59EB2AC96F8911Bd59EB2AC96F8911C4B666Z medecin中讀取圖像問題，但它的所有屬性屬性都是圖像醫生顯示的數據不，我不知道為什么，請大家幫忙，我被困了幾個小時！

Answer 1

錯誤非常明確

屬性“image_medecin”和方法之一“image_medecin()”、“getimage_medecin()”/“isimage_medecin()”/“hasimage_medecin()”或“__call()”都不存在並且在 class“App\實體\醫學”

Twig 嘗試訪問image_medecin中的屬性medecin但它是私有的，不能直接訪問。

所以它嘗試image_medecin() 、 getimage_medecin 、 isimage_medecin() 、 hasimage_medecin()和最后的魔術方法__call() 。

您可以直接在您的 twig 模板中使用正確的方法：

<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">
