Rails 5，未定义的方法`for'for＃<在devise_parameter_sanitizer.for上devise
我正在使用Rails 5
我在模型用户中添加了新的字段用户名。
class Users::RegistrationsController < Devise::RegistrationsController before_action :configure_permitted_parameters protected def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up).push(:username) end end 在注册过程中显示错误： 未定义的方法`for'for＃你的意思是？ 叉子
跟踪：
NoMethodError（未定义的方法`for'for＃你的意思？fork）：

谁可以帮忙？ 如何解决这个问题？
According to the documentation:
Devise 4的Parameter Sanitaizer API已经改变
class ApplicationController < ActionController::Base before_action :configure_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.permit(:sign_up, keys: [:username]) end end
如果您只是将.for更改为.permit它也可以。 例如：
devise_parameter_sanitizer.permit(:sign_up) { |u| u.permit({ roles: [] }, :email, :password, :password_confirmation, :username) }
它可以在Rails 4.2.x和Rails 5.0.x中使用
别忘了devise_parameter_sanitizer.permit(:account_update, keys: [:username])
或者，使用Devise gem version 4.1：
gem 'devise', '~> 4.1.0'
class ApplicationController < ActionController::Base before_action :configure_permitted_paramters, if: :devise_controller? protected def configure_permitted_paramters devise_parameter_sanitizer.permit(:sign_up, keys: [:fullname]) devise_parameter_sanitizer.permit(:account_update, keys: [:fullname, :phone_number, :description, :email, :password]) end end
