创建新用户时的 ActiveModel::ForbiddenAttributesError

本文介绍了创建新用户时的 ActiveModel::ForbiddenAttributesError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在 Ruby 中有这个模型，但它抛出一个 ActiveModel::ForbiddenAttributesError

I have this model in Ruby but it throws a ActiveModel::ForbiddenAttributesError

class User < ActiveRecord::Base attr_accessor :password validates :username, :presence => true, :uniqueness => true, :length => {:in => 3..20} VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i validates :email, presence: true, :uniqueness => true, format: { with: VALID_EMAIL_REGEX } validates :password, :confirmation => true validates_length_of :password, :in => 6..20, :on => :create before_save :encrypt_password after_save :clear_password def encrypt_password if password.present? self.salt = BCrypt::Engine.generate_salt self.encrypted_password= BCrypt::Engine.hash_secret(password, salt) end end def clear_password self.password = nil end end

当我运行此操作时

def create @user = User.new(params[:user]) if @user.save flash[:notice] = "You Signed up successfully" flash[:color]= "valid" else flash[:notice] = "Form is invalid" flash[:color]= "invalid" end render "new" end

在 ruby 1.9.3p194(2012-04-20 修订版 35410)[x86_64-linux].

你能告诉我如何摆脱这个错误或建立一个正确的用户注册表吗?

Can you please tell me how to get rid of this error or establish a proper user registration form?

推荐答案

我猜你正在使用 Rails 4.如果是这样，必须将所需的参数标记为必需.

I guess you are using Rails 4. If so, the needed parameters must be marked as required.

你可能想这样做:

class UsersController < ApplicationController def create @user = User.new(user_params) # ... end private def user_params params.require(:user).permit(:username, :email, :password, :salt, :encrypted_password) end end
