Ошибка при добавлении имен значений для разработки

Question

У меня ошибка при попытке добавить имя значения для разработки, я думаю, что все сделали все, чтобы заставить его работать, но он не работает.

NoMethodError in Devise/registrations#new 

undefined method `name' for #<User:0x00000002e4e038> 

Вот моя модель пользователя:

class User < ActiveRecord::Base 

    include Gravtastic 
    gravtastic :size => 165, :filetype => :png, :rating => 'R' 

    # Include default devise modules. Others available are: 
    # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable, :confirmable 

    validates :email, :username, :presence => true, :uniqueness => true 

    # Setup accessible (or protected) attributes for your model 
    attr_accessible :name, :username, :email, :password, :password_confirmation, :remember_me 

    has_many :topics, :dependent => :destroy 
    has_many :posts, :dependent => :destroy 

    def admin? 
    true if self.username == 'admin' 
    end 

end 

Вот мой вид регистрации:

<h2>Sign up</h2> 

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %> 
    <%= devise_error_messages! %> 

    <p><%= f.label :name %><br /> 
    <%= f.text_field :name %></p> 

    <p><%= f.label :email %><br /> 
    <%= f.email_field :email %></p> 

    <p><%= f.label :password %><br /> 
    <%= f.password_field :password %></p> 

    <p><%= f.label :password_confirmation %><br /> 
    <%= f.password_field :password_confirmation %></p> 

    <p><%= f.submit "Sign up" %></p> 
<% end %> 

<%= render :partial => "devise/shared/links" %> 

А вот мой взгляд регистрация Разрабатывают:

div class="module" style="padding:15px 25px 0px 25px;"> 

    <div style="float:right; width:100%; padding-left:30px; border-left:1px solid #e2e2e2;"> 
    <%= form_for("user", :as => resource_name, :url => registration_path("user")) do |f| %> 
     <%= devise_error_messages! %> 
     <p> 
    Nome: <br /> 
     <%= f.text_field :name, :style => "font-size:2.0em", :autocomplete => "off" %><br /> 
     </p> 
     <p> 
    Usuario: <br /> 
     <%= f.text_field :username, :style => "font-size:2.0em", :autocomplete => "off" %><br /> 
     </p> 
     <p> 
     Email: (apenas emails @usp.br sao aceitos) <br /> 
     <%= f.text_field :email, :style => "font-size:2.0em", :autocomplete => "off" %><br /> 
     </p> 
     <p> 
     Senha:<br /> 
     <%= f.password_field :password, :style => "font-size:2.0em", :autocomplete => "off" %><br /> 
     </p> 
     <p> 
     Confirmar senha:<br /> 
     <%= f.password_field :password_confirmation, :style => "font-size:2.0em", :autocomplete => "off" %><br /> 
     </p> 
     <p><%= f.submit "Criar" %></p> 
    <% end %> 
    </div> 
    <div class="clear"></div> 
</div> 

Я уже tryied rake db: migrate, но это s до этого не решает мою проблему. Извините, я все еще ноб на рельсах.

EDIT: Вот мой миграции файла:

class DeviseCreateUsers < ActiveRecord::Migration 
    def self.up 
    create_table(:users) do |t| 
     t.database_authenticatable :null => false 
     t.recoverable 
     t.rememberable 
     t.trackable 
     t.confirmable 

     # t.encryptable 
     # t.confirmable 
     # t.lockable :lock_strategy => :failed_attempts, :unlock_strategy => :both 
     # t.token_authenticatable 


     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 
    drop_table :users 
    end 
end 

EDIT 2: Вот мой schema.rb

# This file is auto-generated from the current state of the database. Instead 
# of editing this file, please use the migrations feature of Active Record to 
# incrementally modify your database, and then regenerate this schema definition. 
# 
# Note that this schema.rb definition is the authoritative source for your 
# database schema. If you need to create the application database on another 
# system, you should be using db:schema:load, not running all the migrations 
# from scratch. The latter is a flawed and unsustainable approach (the more migrations 
# you'll amass, the slower it'll run and the greater likelihood for issues). 
# 
# It's strongly recommended to check this file into your version control system.

По крайней мере, из этого файла миграции, похоже, вам не хватает name стол для пользователей.

Добавить столбец имен для таблицы пользователей.

rails g migration AddNameToUsers

class AddNameToUsers < ActiveRecord::Migration 
    def change 
    add_column :users, :name, :string 
    end 
end 

Run rake migrate.

Перезагрузите сервер, чтобы быть в безопасности.

ОКОНЧАТЕЛЬНОЕ ИЗДАНИЕ. Больше никогда!!

В миграции файл завещать, раскомментируйте

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

rake db:drop db:create db:migrate

перезагрузка сервера
