Question

我已经检查了其他答案，但是没有找到解决我问题的答案，因为从我的验证中删除“attr_accessor”会给我一个错误，指出“password_confirm是一个未定义的方法”。我构建了这个应用程序，最初能够从登录/注册页面创建新用户。现在，当我尝试创建一个新用户时，我得到两个相互矛盾的错误，我无法弄明白。一个是回滚，显示“用户存在”，但用户没有显示在我的数据库中。另一个是我收到错误消息“密码不能为空”和“密码确认不能为空”，尽管两个字段都已填写。

这是我的控制器代码：

    def create
    user = User.create(name:params[:name], alias:params[:alias], email:params[:email], password:params[:password], password_confirmation:params[:password_confirm])
    if !user.errors.messages.empty?
      puts '********'
      puts user.errors.full_messages
      puts '********'
      flash[:errors] = user.errors.messages
      redirect_to '/users'
    else user && user.authenticate(params[:password])
      puts '********'
      puts user.errors.full_messages
      puts '********'
      session[:id] = user.id
      redirect_to "/ideas"
    end
  end

这是HTML：

    <div class="">
  <h3>Register Here:</h3>
  <form action="/users/create" method="post">
    <input type="hidden" name="authenticity_token" value="<%= form_authenticity_token %>">
    Name:<input type="text" name='name'><br>
    Alias:<input type="text" name='alias'><br>
    Email Address:<input type="text" name='email'><br>
    Password:<input type="text" name='password'><br>
    <p>* Password must be at least 8 characters.</p>
    Confirm Password:<input type="text" name="password_confirm"><br>
    <input type="submit" value="Register">
  </form>
</div>

这是我的模特：

class User < ActiveRecord::Base
  has_secure_password
  has_many :ideas
  has_many :likes
  attr_accessor :password_confirm, :password
  email_regex = /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]+)\z/i
  validates :name, presence: {message: ["Name can't be blank"]}
  validates :alias, presence: {message: ["Alias can't be blank"]}
  validates :password, presence: {message: ["Password can't be blank"]}, :on => :create, length: {minimum: 8}
  validates :password_confirm, presence: {message:["Password Confirmation can't be blank"]}, :on => :create
  validates :email, presence: {message: ["Email name can't be blank"]}, :format => { :with => email_regex}, :uniqueness => { :case_sensitive => false}, :on => :create
  def total_likes
    self.likes.sum(:count)
  end
  def total_posts
    self.ideas.sum(:user_id)
  end
end

删除此行，会弄乱ActiveRecord如何为您处理事情。

attr_accessor :password_confirm, :password

Ruby中的输入字段返回“不能为空”错误
