Error adding value names to devise - ruby-on-rails

Question

Im getting an error trying to add the value name to devise, I think all did all things to make it work, but it doesnt work.
NoMethodError in Devise/registrations#new
undefined method `name' for #<User:0x00000002e4e038>
Here is my user model:
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
Here is my registration view:
<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" %>
And here is my devise registration view:
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>
I already tryied rake db:migrate but it still doesnt solve my problem. Sorry, Im still a noob on rails.
EDIT:
Here is my migration file:
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:
Here is my 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.

Answer 1

At least from that migration file, it seems like you are missing name column for users table.
Add the name column for users table.
rails g migration AddNameToUsers
class AddNameToUsers < ActiveRecord::Migration
def change
add_column :users, :name, :string
end
end
Run rake migrate.
Restart server just to be safe.
FINAL Edit. NEver again!!
In the devise migration file, uncomment
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
restart server
