Question

大家好我正在研究一个symfony 3.3项目，我有一个错误我来不解决它，即使我在这里搜索类似的帖子，但我找不到任何适合我的解决方案。我有两个实体“Cours”和“Categorie”（法语）这两个实体有很多关联。问题是，当我转到创建新Cours的页面时，我收到此错误

属性“类别”也不是其中一种方法 “getCategories（）”，“categories（）”，“isCategories（）”， “hasCategories（）”，“__ get（）”存在并且在课堂上具有公共访问权限 “LearnBundle \实体\ Categorie”。

这是Cours.php代码
