我有一个User实体，我以称为Register的形式收集所有数据。但是一旦注册，我想通过表单编辑用户的某些字段。但是避免某些字段被更新（电子邮件），并且“密码”字段是可选的。我尝试呈现相同的注册表，但是$form->handleRequest($request)抛出错误：
在属性路径中给出的类型为“字符串”，“ NULL”的预期参数 “密码”。
我想知道是否有办法吗？
我尝试了$form->submit($request->request->get($form->getName()),false);
而不是$form->handleRequest($request);，但没有用。
//这是我的控制器。
