我提交时收到此错误，但我无法弄清楚。因为参数发送正确

在此处输入图像描述

应用控制器

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

 before_filter :configure_permitted_parameters, if: :devise_controller?

protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit! }
  end

用户.rb 

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable, :omniauthable

  validates :role, inclusion: { in: ['player', 'team', 'fan'], message: "%{value} can be player, fan or team!" }

注册页面 

<div><%= f.label :role %><br />
<%= f.select :role, ['fan', 'player'].map{|r| [t(r), r]} %>

<%= f.submit "Sign up" %>

注册页面（生成）

<select id="user_role" name="user[role]"><option value="fan">Fan</option>
<option value="player">Pro Player</option></select>

为 Rails 4 设计https://github.com/plataformatec/devise/tree/rails4

gem 'devise', github: 'plataformatec/devise', branch: 'rails4'

对于其他控制器如何使属性允许更改：

例如在用户控制器中

class UsersController < ApplicationController
  def create
    @user = User.create(user_params)
  end

private
  def user_params
    params.require(:user).permit(:email, :role, ...)
  end

使用 Devise 时为用户添加自定义字段的好教程：

编辑

尝试覆盖方法，我认为sign_up_params应该是。registations controller

def sign_up_params
   params.require(:user).permit(:email, :password, :password_confirmation, :other, :etc)
end
