Rails 5，Undefined method`for'for＃< Devise on line devise_parameter_sanitizer.for [英] Rails 5, Undefined method `for' for #<Devise on line devise_parameter_sanitizer.for

问题描述

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_pa​​rameters 
 
 protected 
 
 def configure_permitted_pa​​rameters 
 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'你的意思是？ fork

跟踪：

NoMethodError（未定义的方法`for'为＃
你的意思是fork）：

  app / controllers / users / registrations_controller.rb：7：在`configure_permitted_pa​​rameters'

谁能帮忙？如何解决这个问题？

解决方案

根据文档：

参数Sanitaizer API已经改变了Devise 4

  class ApplicationController< ActionController :: Base 
 before_action：configure_permitted_pa​​rameters，如果：：devise_controller？ 
 
 protected 
 
 def configure_permitted_pa​​rameters 
 devise_parameter_sanitizer.permit（：sign_up，keys：[：username]）
 end 
 end 
  

I am working with Rails 5

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

During registration is displayed error: undefined method `for' for # Did you mean? fork

Trace:

NoMethodError (undefined method `for' for # Did you mean? fork):

Who can help? How solve this problem?

解决方案

According to the documentation:

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
