问题描述

我正在使用 Rails 5

I am working with Rails 5

我在模型用户中添加了新的字段用户名.

I aded new field username in model User.

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:undefined method `for' for # 你的意思是?叉

推荐答案

根据文档:

Devise 4 的 Parameter Sanitaizer API 已更改

The Parameter Sanitaizer API has changed for Devise 4

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
