最近从Rails 3更新到Rails 4，我目前在Devise中遇到自定义字段的问题。我已经在stackoverflow上阅读了文档和许多帖子，但似乎仍有问题。
我在服务器日志中看到的错误如下：
Unpermitted parameters: f_name, l_name, phone
ArgumentError (wrong number of arguments (0 for 1)):
有人能在这里发现问题吗？
# controllers/users/registrations_controller.rb
class Users::RegistrationsController < Devise::RegistrationsController

def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:f_name, :l_name, :phone) }
end
end
