Ruby on rails 要获得一个包含地址、头像、电话号码等附加字段的个人资料页面，我缺少什么

我使用RubyonRails并使用Desive进行登录和注册。注册后，我收到以下错误消息：

NoMethodError in Devise::SessionsController#create undefined method profile_path' for #<Devise::SessionsController:0x007f9425b1f9c0>

谢谢。

您需要在

application\u controller.rb

中使用复数：

profiles\u path

而不是

profile\u path

，要添加新字段，您必须编写迁移。我看不出你面临什么错误或问题。你能解释一下你的问题吗？你的错误信息在哪里？我很抱歉忘了发布错误：Desive:：SessionController#为提取的源创建未定义的方法
