ActiveModel::MassAssignmentSecurity::Error in Devise::RegistrationsController#create

[mzaragoza]

i am trying to update Divice so my Usermodel has a firstname, lastname, and not just a email and password

so i created a migration

db/migrate/20120521142938_add_username_fistname_lastname_to_users.rb

class AddFistnameLastnameToUsers < ActiveRecord::Migration
def change
add_column :users, :fistname, :string
add_column :users, :lastname, :string
end
end

i also did

rails generate devise:install

To be able to modify the views

This is the new account view
app/views/devise/registrations/new.html.erb

Sign up

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

<%= f.label :email %>
<%= f.email_field :email %>

<%= f.label :password %>
<%= f.password_field :password %>

<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation %>

<%= f.label :fistname %>
<%= f.text_field :fistname %>

<%= f.label :lastname %>
<%= f.text_field :lastname %>

<%= f.submit "Sign up" %>

<% end %>

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

my Error
When i submit this form i get a error that reads

ActiveModel::MassAssignmentSecurity::Error in Devise::RegistrationsController#create
