【问题描述】：
我正在尝试在使用 devise 时自定义我的输入参数。在我的能力范围内，我已经关注了devise doc 的主题。我还广泛搜索了一些有用的文章，例如this one。最后，当我填写表单并点击提交时，会返回新用户页面上的“sign_up”表单。当我在控制台中检查数据库时，没有添加新用户，下面列出了服务器日志和相关代码。如果您想查看任何其他代码，请告诉我并更新问题。非常感谢任何和所有帮助。
服务器日志：

我的应用程序控制器：

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

def account_sign_in
default_paramiters.permit(:first_name, :last_name, :handle, :email, :password, :password_confirmation, :current_password)
end

编辑(1)
创建新文件 app/controllers 中的registrations_controller.rb 类 RegistrationsController
private
def configure_devise_params
devise_parameter_sanitizer.for(:sign_up) do |u|
u.permit(:email, :password, :password_confirmation)
end
end
end
修改了 routes.rb 中的 devies_for 路由以指向新的控制器。
devise_for :users, :controllers => {:registrations => "registrations"}
最后，我在应用程序控制器中注释掉了对 devise_parameter_sanitizer 的引用并删除了
require "#{Rails.application.root}/lib/user_sanitizer.rb"
在 sanitizers.rb 中
