我正在为用户使用 Devise，但是当我尝试显示用户名和姓氏时，在视图页面中我只看到 0。

看法：

    <% if user_signed_in?%>
        <div id="admin_bar">
            <ul>
                <li>Lapini lūgti, <%= current_user.name %> <%= current_user.surname %> administratora panelī!</li>
            </ul>
        </div>  
    <% end %>

用户迁移：

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|

      t.integer :name,      :null => false
      t.integer :surname,   :null => false

      t.timestamps
    end
  end
  def self.down
    drop_table :users
  end
end

将设计添加到我的用户的设计迁移：

class AddDeviseToUsers < ActiveRecord::Migration
  def self.up
    change_table(:users) do |t|
      ## Database authenticatable
      t.string :email,              :null => false, :default => ""
      t.string :encrypted_password, :null => false, :default => ""

      ## Recoverable
      t.string   :reset_password_token
      t.datetime :reset_password_sent_at

      ## Rememberable
      t.datetime :remember_created_at

      ## Trackable
      t.integer  :sign_in_count, :default => 0
      t.datetime :current_sign_in_at
      t.datetime :last_sign_in_at
      t.string   :current_sign_in_ip
      t.string   :last_sign_in_ip

      ## Confirmable
      # t.string   :confirmation_token
      # t.datetime :confirmed_at
      # t.datetime :confirmation_sent_at
      # t.string   :unconfirmed_email # Only if using reconfirmable

      ## Lockable
      # t.integer  :failed_attempts, :default => 0 # Only if lock strategy is :failed_attempts
      # t.string   :unlock_token # Only if unlock strategy is :email or :both
      # t.datetime :locked_at

      ## Token authenticatable
      # t.string :authentication_token


      # Uncomment below if timestamps were not included in your original model.
      # t.timestamps
    end

    add_index :users, :email,                :unique => true
    add_index :users, :reset_password_token, :unique => true
    # add_index :users, :confirmation_token,   :unique => true
    # add_index :users, :unlock_token,         :unique => true
    # add_index :users, :authentication_token, :unique => true
  end

  def self.down
    # By default, we don't want to make any assumption about how to roll back a migration when your
    # model already existed. Please edit below which fields you would like to remove in this migration.
  end
end

和我的用户模型：

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :name, :surname
  # attr_accessible :title, :body
end

我在这里缺少什么？

通常人们的名字和姓氏是字符串，而不是整数。而不是这个：

t.integer :name,      :null => false
t.integer :surname,   :null => false

用这个：

t.string :name,      :null => false
t.string :surname,   :null => false
