在rails中保存自定义字段rails中的用户模型4 [英] Saving custom fields in devise User model in rails 4

问题描述

我做了一个设计用户模型，并添加了其他字段。当我创建和帐户一切正常，只有通过电子邮件，pw和pw conf。

I made a devise User model and added additional fields to it. When I create and account everything works fine, only with email, pw and pw conf.

然后我想允许用户去编辑页面并填写可选附加字段。
但是，当它们提交时，所有内容都保存为nil。

I then want to allow the user to go to edit page and fill in the optional additional fields. But, when they submit, everything is saved as nil.

 class RegistrationsController < Devise::RegistrationsController

   before_action :configure_permitted_parameters, if: :devise_controller?

   def configure_permitted_parameters
     devise_parameter_sanitizer.for(:sign_in){ |u| u.permit(:email, :password) }
     devise_parameter_sanitizer.for(:sign_up){ |u| u.permit(:name, :username, :about,  :email, :password, :password_confirmation)}
     devise_parameter_sanitizer.for(:account_update){ |u| u.permit(:name, :username, :about, :email, :password, :password_confirmation) }
   end

   def update
     self.resource = resource_class.to_adapter.get!(send(:"current_#{resource_name}").to_key)
     if resource.update_with_password(user_params)
       if is_navigational_format?
         flash_key = update_needs_confirmation?(resource, prev_unconfirmed_email) ? :update_needs_confirmation : :updated
         set_flash_message :notice, flash_key
       end
       sign_in resource_name, resource, :bypass => true
       respond_with resource, :location => after_update_path_for(resource)
     else
       clean_up_passwords resource
       respond_with resource
     end
   end

   def user_params 
     params.require(:user).permit(:email, :password, :current_password, :password_confirmation, :name, :username, :about) 
   end
 end

我在控制台中得到这个输出，

I get this output in the console,

 ActiveRecord::SchemaMigration Load (0.1ms)  SELECT "schema_migrations".* FROM "schema_migrations"
 Processing by Devise::RegistrationsController#update as HTML
 Parameters: {"utf8"=>"✓", "authenticity_token"=>"EG8FtCTBohuG2uwUvIqmY7KTsmYY1nMAXqTfc0Li+eQ=", 
 "user"=>{"email"=>"[e-mail]", "name"=>"Aaron", "username"=>"", "about"=>"", 
 "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "current_password"=>"[FILTERED]"}, "commit"=>"Update"}

User Load (2.2ms)  SELECT "users".* FROM "users" WHERE "users"."id" = ? LIMIT 1  [["id", 1]]
Unpermitted parameters: name, username, about

但是，当我在控制台（使用User.last）登录时，数据库中没有保存任何内容。我陷入困境，并且不知道有什么问题...

But nothing is saved in the database when I check in the console (with User.last). I am stuck, and have looked and have no idea what is wrong...

推荐答案

在Rails4中，我们有很强的参数，所以请

In Rails4 we have strong parameters so please

将以下行添加到您的application_controller.rb中

Add following line to your application_controller.rb

before_filter :configure_devise_params, if: :devise_controller?
  def configure_devise_params
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:first_name, :last_name, :gender, :email, :password, :password_confirmation)
    end
  end
