Question

我对表单视图中的数据有疑问

原理与该视频（https://www.youtube.com/watch?v=MRfsHix1eRA&t=1257s）相同，也就是说：当我选择“管理”时，我希望与此“管理”相关联的“服务”。 这些必须在“报告表单”（报告实体）中选择。 OneOrMany服务已链接至一个管理人员，而报告已链接至管理人员和服务。

当我转储（）我的$ form-> getData（）-> getServices（）时，这将返回一个集合。但我收到此消息：属性“ service”或方法“ service（）”，“ getservice（）” /“ isservice（）” /“ hasservice（）”或“ __call（）”都不存在并且没有类“ Symfony \ Component \ Form \ FormView”中的公共访问。

在{{form_widget（form.service，{'attr'：{'placeholder'：“ Service”}}）}}

有些人有解决方案？

如果您需要，我可以提供更多信息 谢谢。
