我正在尝试向我的注册页面添加一个使用设计的字段。我按照设计文档中的说明进行操作。新字段是“角色”字段。我已经成功地将它迁移到数据库中。我现在正在努力使注册工作。这是新的应用程序控制器:

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

    def devise_parameter_sanitizer
        if resource_class == User
          User::ParameterSanitizer.new(User, :user, params)
        else
          super # Use the default one
        end
    end
end

这是更改后的用户模型:

class User::ParameterSanitizer < Devise::ParameterSanitizer
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  def sign_up
    default_params.permit(:email, :role)
  end
end 

一旦我添加了这两个文件,服务器甚至无法加载。如何成功添加角色字段?

编辑

这是我的 routes.rb 文件

devise_for :users
root 'static_pages#home'
get 'student' => 'static_pages#index'

您还可以使用以下方法在设计用户表中添加自定义字段。

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

  before_filter :configure_permitted_parameters, if: :devise_controller?

  def configure_permitted_parameters
   devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:firstname, :lastname, :email, :password, :password_confirmation) } # The :firstname and :lastname are my custom fields.
  end

  protect_from_forgery with: :exception
end
