Rails设计不会将额外的输入字段保存到数据库

我在使用Devise gem将额外的用户字段值插入数据库时​​遇到问题。 我错过了什么？

我正在使用

ruby 2.1.5p273 Rails 4.1.8 

这是我的user.rb模型

 class User  [:login] attr_accessor :login, :name, :last_name, :address, :post_number, :city, :mobile validates :username, presence: true, length: {maximum: 25}, :uniqueness => { :case_sensitive => false } validates :name, presence:true validates :last_name, presence:true validates :address, presence:true validates :post_number, presence:true validates :city, presence:true validates :country, presence:true validates :mobile, presence:true def login=(login) @login = login end def login @login || self.username || self.email end def self.find_for_database_authentication(warden_conditions) conditions = warden_conditions.dup if login = conditions.delete(:login) where(conditions).where(conditions).where(["username = :value OR lower(email) = lower(:value)", { :value => login }]).first else where(conditions).first end end end 

我的应用程序控制器

 class ApplicationController < ActionController::Base # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. protect_from_forgery with: :exception before_action :configure_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up) << :username << :email << :password << :password_confirmation << :remember_me << :name << :last_name << :address << :post_number << :city << :country_id << :mobile devise_parameter_sanitizer.for(:sign_in) << :login << :username << :email << :password << :remember_me devise_parameter_sanitizer.for(:account_update) << :username << :email << :password << :password_confirmation << :current_password << :name << :last_name << :address << :post_number << :city << :country_id << :mobile end end 

应用控制器（V2，我试过船方）

 class ApplicationController < ActionController::Base # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. protect_from_forgery with: :exception before_action :configure_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password, :password_confirmation, :remember_me, :name, :last_name, :address, :post_number, :city, :country_id, :mobile) } devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :username, :email, :password, :remember_me) } devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:username, :email, :password, :password_confirmation, :current_password, :name, :last_name, :address, :post_number, :city, :country_id, :mobile) } end end 

Registratiions / new.html.erb

这是一个日志，当我提交表单时会发生什么

我有两个问题：

1. 我必须做什么，所以设计将扩展他的INSERT SQL查询以插入额外的数据库字段值？
2. 编写应用程序控制器devise_parameter_sanitizer的方法是正确的？

谢谢你的帮助

我找到了解决方案！ 在rails 4中，您必须在控制器中指定user_params

这是我的users_controller（添加了user_params）

 class UsersController < ApplicationController def index @users = User.all end def new @user = User.new end private def user_params params.require(:user).permit(:username, :email, :password, :password_confirmation, :remember_me, :name, :last_name, :address, :post_number, :city, :country_id, :mobile) end end 

这是我的用户模型（删除了attr_accessor）

  class User < ActiveRecord::Base belongs_to :country # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :confirmable, :authentication_keys => [:login] validates :username, presence: true, length: {maximum: 25}, :uniqueness => { :case_sensitive => false } validates :name, presence:true, length: {maximum: 30} validates :last_name, presence:true validates :address, presence:true validates :post_number, presence:true validates :city, presence:true validates :country, presence:true validates :mobile, presence:true def login=(login) @login = login end def login @login || self.username || self.email end def self.find_for_database_authentication(warden_conditions) conditions = warden_conditions.dup if login = conditions.delete(:login) where(conditions).where(conditions).where(["username = :value OR lower(email) = lower(:value)", { :value => login }]).first else where(conditions).first end end end 

这是我的应用程序控制器

 class ApplicationController < ActionController::Base # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. protect_from_forgery with: :exception before_action :configure_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up) do |u| u.permit(:username, :email, :password, :password_confirmation, :remember_me, :name, :last_name, :address, :post_number, :city, :country_id, :mobile) end devise_parameter_sanitizer.for(:sign_in) do |u| u.permit(:login, :username, :email, :password, :remember_me) end devise_parameter_sanitizer.for(:account_update) do |u| u.permit(:username, :email, :password, :password_confirmation, :current_password, :name, :last_name, :address, :post_number, :city, :country_id, :mobile) end end end
