Ruby on rails 4 获得；“不允许的参数”；deivse的错误

嗨，我正在开发示例应用程序，我正在使用Desive进行身份验证。 我在注册时添加以下额外参数

:first_name, :last_name, :mobile, :gender, :address

但我得到了以下

未被允许的参数：名字、姓氏、密码确认

注册新用户时出错

我推荐了以下链接

但它不起作用。这里不是代码集

user.rb

class User < ActiveRecord::Base

  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  validates_confirmation_of :password, :only => :create
end

class RegistrationsController < Devise::RegistrationsController

  before_filter :configure_permitted_parameters

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|      
      u.permit(:first_name, :last_name, :mobile, :gender, :address, :email, :password, :password_confirmation)
    end
    devise_parameter_sanitizer.for(:account_update) do |u|
      u.permit(:name,
      :email, :password, :password_confirmation, :current_password)
    end
  end
end

class ApplicationController < ActionController::Base

  protect_from_forgery with: :exception

  private
  def after_sign_in_path_for(resource)
    user_landing_page
  end

  def user_landing_page
    contact_us_path      
  end
end

Rails.application.routes.draw do
  root :to => 'landing#index'  
  devise_for :users, :controllers => {:registrations => "registrations"}
  get '/about_us' => 'statics#about_us', as: :about_us
  get '/contact_us' => 'statics#contact_us', as: :contact_us
end

谁能告诉我我错过了什么。

我正在使用Rails 4.1.4、ruby 2.1.2和Desive 3.4.1。

据我所知，您正在注册新用户。这是你的错误

= form_for(resource, as: resource_name, class: "form-signin input-medium", url: session_path(resource_name)) do |f|

您使用的是

session\u path

，这意味着您要“登录”而不是“注册”。所以改变它

= form_for(resource, as: resource_name, class: "form-signin input-medium", url: registration_path(resource_name)) do |f|
