Rails 3 Error message

i got the error DEPRECATION WARNING: error_messages_for was removed from Rails and is now available as a plugin. Please install it with rails plugin install git://github.com/rails/dynamic_form.git. (called from _app_views_user_register_html_erb__195833478_79197384_0 at C:/Users/rod/connect-my-friends/app/views/user/register.html.erb:5)

i got the plugin and did a rake but i still get the error did i not do something right?

here is what the page code looks like

<%= form_for :user do |form| %>
 <fieldset>
  <legend>Enter Your Details</legend>
  <%= error_messages_for "user" %>
  <div class="form_row">
   <label for="screen_name">Screen name:</label>
   <%= form.text_field :screen_name,
        :size => User::SCREEN_NAME_SIZE,
        :maxlength => User::SCREEN_NAME_MAX_LENGTH %>
  </div>

i believe that should be enough info if ya need more ask and I'll edit this and add it

    require File.expand_path('../boot', __FILE__)

require 'rails/all'

# If you have a Gemfile, require the gems listed there, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env) if defined?(Bundler)

module ConnectMyFriends
  class Application < Rails::Application
    # Se开发者_C百科ttings in config/environments/* take precedence over those specified here.

    config.encoding = "utf-8"

    # Configure sensitive parameters which will be filtered from the log file.
    config.filter_parameters += [:password]
  end
end

this is all new to me so i added the aplaction.rb file not sure how to put that in

Check the plugin's README

My guess is that you should use form.error_messages instead of error_messages_for "user".

--edit

Other guesses:

• Have you restarted the server after installation?
• Are you loading all your plugins? Check config/application.rb -> config.plugins.
