Rails 5，行devise_parameter_sanitizer.for上#<Devise的未定义方法‘for’
提问于 2016-05-20 16:40:34
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注册过程中显示错误：未定义#的方法‘for’你是指什么？fork
跟踪：
NoMethodError (#的未定义方法‘for’你是指？fork)：
app/controllers/users/registrations_controller.rb:7:in `configure_permitted_parameters'

According to the documentation:
Devise 4的Sanitaizer参数API已更改
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

如果您只需将.for更改为.permit，它也可以正常工作。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中运行

别忘了devise_parameter_sanitizer.permit(:account_update, keys: [:username])
