我的代码片段如下

views/users/new.html.erb

<center>
  <h1>Enter your data</h1>
  <% if @user.errors.any? %>
      <div id="error_explanation">
        <h2><%= pluralize(@user.errors.count, "error") %> prohibited this post from being saved:</h2>

        <ul>
          <% @user.errors.full_messages.each do |message| %>
              <li><%= message %></li>
          <% end %>
        </ul>
      </div>
  <% end %>
  <div class="form-div">
   <%= form_for :user,:url => {:action => 'create'} do |f|%>
    <p>
      <%= f.label :Name %>
      <%= f.text_field :name,placeholder:"Enter your name" %>
    </p>
        <p>
          <%= f.label :Email %>
          <%= f.email_field :email,placeholder:"Enter your Email" %>
        </p>
        <p>
          <%= f.label :Password %>
          <%= f.password_field :password,placeholder:"Enter your password" %>
        </p>
        <p>
          <%= f.label :password %>
          <%= f.password_field :con_password,placeholder:"Enter your password again" %>

        <p>
          <%= f.label :content %>
          <%= f.text_field :content,placeholder:"Enter your content" %>

class User < ActiveRecord::Base
  attr_accessible :content, :email, :name, :password
  EMAIL_REGEX = /\A[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\z/i

迁移\20150128062543\u创建\u用户.rb

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|
      t.string :name
      t.string :email
      t.string :password
      t.string :content

      t.timestamps
    end
  end
end

请帮助我解决此问题。

您应该将您的字段密码命名为“确认”，而不是“确认”，因为如果您的模型具有validates:password，confirmation:true:

---

您还必须向模型中可访问的属性添加密码确认

否，在添加行@Marek后再次显示相同的错误。你还有其他解决办法吗？@Subhra\u代理忘记了attr\u。检查我编辑的答案。将所有数据放在适当的位置后，现在它工作正常。

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|
      t.string :name
      t.string :email
      t.string :password
      t.string :content

      t.timestamps
    end
  end
end

<%= f.password_field :password_confirmation, placeholder: "Enter your password again" %>
